Window replacement cost dataset

What ten windows cost, and what one costs

National figures for a vinyl insert with an ENERGY STAR glass package for the North-Central zone, standard-size openings, capped exteriors, up to four openings upstairs and up to two needing tempered glass. Only the number of windows changes down this column.

The per-window figure falls from $1,918 to $1,080 between one window and twenty, and the reason is not a volume discount that somebody chose to model. It is that three things are paid for once whatever the count: rigging the staging, setting the brake to the profile of the house, and getting the debris to the tip. A single window pays a twenty-fifth of a truck run plus five minutes of handling, not a dedicated round trip, because in domestic work the sashes go out with the rest of the week.

Insert against full-frame

Ten standard openings, everything else identical. Both jobs are sold with the same sentence and they are not the same job: the line count is the clearest way to see it.

The difference is $8,353 on ten windows, and it is not a markup: a full-frame job buys a sill pan and flashing tape, exterior casing and head flashing, jamb extensions, interior casing, stool and apron, three hours of carpentry per opening and the paint that puts the room back. It also produces three and a half times the debris. An insert buys none of that and cannot: the flashing plane is behind the cladding and an insert never opens the cladding. Which one your house needs is decided by whether the existing frame is sound, and that is a question for somebody standing in front of it.

ENERGY STAR is four different windows

ENERGY STAR, Windows, doors and skylights publishes that the performance criteria for windows and skylights are based on ratings certified by the National Fenestration Rating Council and vary for each climate zone. Retrieved 2026-08-22. So “it is ENERGY STAR” does not describe a window until the zone is named. The uplift each zone costs is our estimate; the fact that they differ is theirs.

Frame material, and the size of the hole

Ten standard openings, insert installation. Windows are manufactured goods shipped nationally, so none of these unit prices carries a regional adjustment: what moves with where you live is the labour beside them.

Thermally broken aluminium sits where it does on purpose. The cheap aluminium windows people remember are the ones without a thermal break, and those are a different product that this dataset does not price: without a polyamide or polyurethane barrier the frame conducts and the room gets condensation running down it. Pricing architectural aluminium as a budget option was the single largest correction this dataset has had.

Three factors rather than one, because a bigger window does not make everything bigger in the same proportion. Glass area drives the unit price, handling drives the hours, and anything bought by the joint — foam, backer rod, sealant, flashing tape, coil stock — follows the perimeter. An oversize opening has 2.10 times the glass of a standard one but only 1.42 times the edge, which is geometry rather than opinion: 3 ft by 5 ft is 15 sq ft and 16 linear feet of joint, and 32 sq ft in similar proportion is about 22.6 linear feet.

What comes out changes the hours

Ten standard insert openings. The factor applies to the insert hours only: on a full-frame job the old frame comes out whole whatever it is made of, so what it is made of barely matters.

The wage behind each labour line

Hourly rates come from BLS Occupational Employment and Wage Statistics, May 2025, retrieved 2026-08-20. BLS does not publish every occupation in every area, and this is the table nobody else shows: where an occupation is missing, the model falls back to the wider occupational group for that same area and the calculator says which one it used. A figure adjusted by sector is still local; it is simply not the same promise as one adjusted by trade, and calling the second one the first is the kind of claim anybody can check in a minute.

Read the first row before you read anything else on this page. Glaziers are published in 194 of 530 areas, which means that for most of the country — Atlanta included — the fitting hours are priced from the construction and extraction group instead. The driver is published in all 530, so the haul is the one labour line here that never falls back. The hours themselves are ours in every case: BLS publishes what people are paid, never how long a job takes, and a labour total made of an official wage and an unofficial duration is not an official number.

Line items

Conditional lines appear only when the corresponding answer applies, and several of them are zero on an insert job rather than being charged quietly anyway. Labour lines carry the trade whose published wage pays for them.

The reasoning behind each figure

Written out so a window contractor can point at the exact assumption that is wrong. A number with no reasoning behind it cannot be corrected.

Vinyl replacement window unitestimated, ±47%

• The unit only: frame, sash, hardware and the sealed glass package that comes with it. Nothing to do with fitting it, which is priced in hours further down.
• The band is nearly three to one and that is honest. The bottom is a builder-line double-hung with a single-strength sealed unit and a hollow frame; the top is a heavy-wall extruded frame with fusion-welded corners, a warm-edge spacer, foam-filled chambers and metal-reinforced meeting rails. Both are sold as "vinyl windows" and the floor of this band is what a base-price quote means.
• Windows are manufactured goods shipped nationally, so this line carries no regional adjustment. What moves with where you live is the labour below it.
• Priced per standard-size window of roughly 15 sq ft. A larger opening multiplies this line by the size factor shown with your answer, because glass area is what the unit costs.

Fiberglass replacement window unitestimated, ±40%

• Fiberglass expands and contracts at almost the same rate as the glass it holds, which is the whole argument for it: the seal between frame and glass is not being worked loose every summer and winter.
• The frame sections are narrower than vinyl for the same strength, so a fiberglass unit puts more glass in the same rough opening. That is a visible difference, not a spec-sheet one.
• The band separates a painted stock colour from a factory-finished custom size. Fiberglass is made to order far more often than vinyl, and made-to-order is most of the spread. There is no bargain end to this material: the entry lines start where vinyl stops, which is why the floor of this band sits above the top of a builder-grade vinyl unit.
• Manufactured nationally, so no regional adjustment on this line.

Clad-wood replacement window unitestimated, ±51%

• Wood on the inside to stain or paint, an aluminium or fibreglass skin on the outside so the weather never touches the timber. It is the expensive end of this page and often the only thing a historic district will approve.
• The band is the widest of the four materials because it spans the most product: a stock pine unit in a standard size at the bottom, a factory-finished hardwood interior with a custom exterior colour and simulated divided lights at the top.
• A clad-wood unit is also the one most likely to arrive weeks after it is ordered, which is a scheduling cost this figure cannot contain.
• Manufactured nationally, so no regional adjustment on this line.

Thermally broken aluminium replacement window unitestimated, ±44%

• Aluminium carries the largest openings without a fat frame, which is why it survives in the South and in coastal high-wind construction where vinyl will not span.
• The thermal break is not optional and it is what separates this band from a cheap aluminium window: without a polyamide or polyurethane barrier between the inside and the outside of the frame, the frame conducts and the room gets condensation running down it in winter.
• This is the line where a cost page most often misleads, and this one used to. A thermally broken aluminium window is not a budget product in the 2026 replacement market: the cheap aluminium windows people remember are the ones without the break, and those are a different item that this page does not price. What is left is architectural product, and it costs two to three times a vinyl unit rather than a little more.
• The bottom of the band is a stock mill finish in a standard size; the top is a coastal-rated unit with an anodised or powder-coated finish and impact glazing hardware. Impact glazing for a coastal jurisdiction can exceed even the top of this band, and it is listed in the exclusions rather than averaged in, because it applies to a minority of the country and would distort every other answer.
• Manufactured nationally, so no regional adjustment on this line.

ENERGY STAR glass package for the Northern zoneestimated, ±51%

• The uplift over a builder-grade double-glazed unit, not the price of the glass. ENERGY STAR criteria are based on NFRC-certified ratings and vary by climate zone, so this uplift is different in every zone and this is the dearest of the four.
• What the Northern criterion asks for is a low U-factor, and reaching it normally means two coated surfaces, a warm-edge spacer and a heavier gas fill. Some product lines can only get there with a third pane, which is why this band runs up to three times the Southern one.
• The band is our estimate of what that glass package adds at the order desk. There is no published national price for a glazing option, which is exactly why it is declared as an estimate rather than dressed up as a quote.
• Buying "an ENERGY STAR window" without knowing your zone is buying a label. The zone is what says which window the label means.

ENERGY STAR glass package for the North-Central zoneestimated, ±53%

• The uplift over a builder-grade double-glazed unit. Heating still dominates in this zone, so the criterion that bites is still the U-factor — but it is reachable with a good double-glazed unit rather than forcing a third pane.
• That is the whole reason this band sits below the Northern one for the same badge on the same window: same label, less glass to buy.
• ENERGY STAR criteria are based on NFRC-certified ratings and vary by climate zone. The rating is certified; what the option costs at the order desk is our estimate, and the band says how sure we are.

ENERGY STAR glass package for the South-Central zoneestimated, ±57%

• The uplift over a builder-grade double-glazed unit. This zone is the awkward one: a real cooling season and a real cold snap, so the coating has to hold heat in and keep solar gain out at the same time.
• That double requirement is why the band is wider in proportion than the Southern one — the product that satisfies both criteria is not always the cheapest glass in the catalogue.
• ENERGY STAR criteria are based on NFRC-certified ratings and vary by climate zone. The uplift itself is our estimate.

ENERGY STAR glass package for the Southern zoneestimated, ±57%

• The uplift over a builder-grade double-glazed unit, and the cheapest of the four zones. In the South the criterion that bites is solar heat gain rather than U-factor, so what you are buying is a spectrally selective coating on the outer pane, not more panes.
• This is the zone where a homeowner is most likely to be sold a triple-glazed window they do not need. The label they are shown is the same label; the criterion behind it is not.
• ENERGY STAR criteria are based on NFRC-certified ratings and vary by climate zone. What the coating adds at the order desk is our estimate.

Triple-glazing upgradeestimated, ±45%

• Three panes and two coated cavities, over a builder-grade double-glazed unit. It is the most expensive glass option on this page and, in the warm zones, the one with the weakest case behind it.
• The top of the band is a krypton fill, which is what a narrow triple cavity needs to beat argon, and krypton is the single most expensive gram in a window.
• A triple-glazed sash is heavy. It loads the balances and the hinges harder, and in an insert installation the extra weight goes onto a frame that was sized for a lighter sash decades ago.
• Not every window that qualifies for ENERGY STAR needs three panes, and not every triple-glazed window qualifies. They are different questions and the calculator keeps them apart on purpose.

Tempered safety glazing upcharge on the openings that require itestimated, ±45%

• This is the line the code puts on the order sheet and that almost no cost page carries. Residential building codes require safety glazing — in practice tempered glass — in specific locations: glass close to a door, glass low enough to walk into, glass beside a bath or shower, and glass in or beside a stairway. Which openings those are is decided by your local building department against the code your jurisdiction has adopted, and it is worth asking before the order goes in rather than after.
• On a typical job of eight to twelve windows it is one to three openings, and it is a per-unit upcharge from the manufacturer rather than something the installer adds. It is not optional and it is not negotiable: a supplier will not ship an uncertified unit into a location the code names.
• The band is the spread of what manufacturers charge for the option across product lines. It scales with the size factor because tempering is priced on the glass area being toughened.
• Finding out after the units arrive is the expensive version of this line, because a window that has to be reordered in tempered glass is a second lead time as well as a second price. That is the practical reason it is an input here rather than a footnote.

Grilles and a non-white exterior finishestimated, ±76%

• Two order-sheet options that more than half the replacement market asks for and that a base price never includes: grilles, and any exterior colour other than white.
• The bottom of the band is grilles between the glass — a spacer grid sealed inside the insulated unit, which is the cheap way and the way that never needs painting. The top is simulated divided lights, which are bars bonded to both faces of the glass with a spacer between the panes so the window reads as individual panes from the street. They are the same idea at seven times the price and they are not interchangeable to look at.
• A laminated or coextruded exterior colour on a vinyl frame is fifty to a hundred and fifty dollars a window on its own, because it is a different extrusion running through the factory rather than a finish applied at the end.
• This is one line rather than four because it is one decision made at the order desk. It is priced per opening and scaled by the size factor, since both the grid and the colour follow the size of the unit.

Insert installation consumables: shims, low-expansion foam, sealant and fastenersestimated, ±47%

• Composite shims, low-expansion window foam, backer rod, exterior-grade sealant and the screws that go through the jambs into the old frame. Materials only.
• The foam has to be the low-expansion kind. Ordinary gap foam bows a replacement jamb inward and the sash then binds, which is the most common self-inflicted callback on this job.
• Sealants and foams carry a minimum application temperature on the can. That is a real constraint on winter work and it is why this line does not carry a seasonal discount: we have no source for one.
• This line scales with the PERIMETER of the opening, not with its glass area, because a bead of sealant follows the joint and the joint follows the edge. A 32 sq ft opening has 2.1 times the glass of a standard one but only about 1.4 times the perimeter, so the size factor here is 1.42 and not 2.1.
• Small commodity goods bought nationally, so no regional adjustment on this line.

Full-frame installation consumables: sill pan, flashing tape, housewrap patch, foam and sealantestimated, ±47%

• A sloped sill pan, self-adhered flashing tape at the sill and jambs, a patch of housewrap lapped correctly over the head flashing, low-expansion foam, backer rod and sealant. Materials only.
• This is the half of a full-frame job that nobody sees and that decides whether the opening leaks in ten years. An insert cannot buy it at any price, because the flashing plane is behind the cladding and an insert never opens the cladding.
• The band separates a taped-and-folded sill pan made on site from a moulded pan with end dams, and a straightforward housewrap lap from one that has to be cut into stucco or brick veneer. A moulded pan with end dams is thirty to sixty-five dollars on its own and a roll of good self-adhered flashing does about four openings, which is what sets the floor of this band.
• Like the insert consumables, this scales with the perimeter of the opening rather than its glass area: flashing tape follows the edge of the hole.
• Commodity materials bought nationally, so no regional adjustment on this line.

Aluminium coil stock and trim nails to cap the existing exterior frameestimated, ±56%

• On an insert installation the old exterior wood frame stays in the wall, and it is still the part the weather hits. Capping wraps it in bent aluminium coil so it never needs painting again.
• Materials only: the coil stock, the trim nails and the sealant. The bending is done on site on a brake, and those hours are on the line below.
• Skipping this is the cheapest way to make an insert quote look competitive, and it leaves bare or painted wood exposed at the one place on the wall where water is directed.
• Coil stock is bought by the running foot and bent to the perimeter of the opening, so this line carries the perimeter factor and not the glass-area one.
• Coil stock is a national commodity, so no regional adjustment on this line.

New exterior casing or brickmould, head flashing and sealantestimated, ±52%

• A full-frame replacement takes the old exterior casing off with the frame, so new trim is not an upgrade here: it is what closes the hole. PVC or composite brickmould, a metal head flashing and the sealant that finishes it.
• The floor of this band is set by arithmetic, not by opinion: a standard 3 ft by 5 ft opening has sixteen linear feet of trim around it, and PVC brickmould in 2026 is three and a half to five and a half dollars a foot. That is fifty-six to eighty-eight dollars in mouldings alone before the head flashing and the sealant, which is why nothing below seventy dollars is a real number here.
• The band separates a straight run of stock PVC casing on lap siding from a profile matched to an existing house on brick or stucco, where the trim has to be made to fit what is already there.
• Materials only. Fitting them is carpenter time and it is priced by the hour further down.
• Trim stock is bought nationally, so no regional adjustment on this line.

Jamb extensions, interior casing, stool and apron, caulk and fillerestimated, ±55%

• The inside of a full-frame opening comes back as bare framing, so the interior has to be rebuilt: jamb extensions ripped to the wall thickness, casing, a stool and apron if the house has them, plus caulk and filler.
• This is the line that surprises people. An insert leaves the interior casing untouched and this material is simply not bought; a full-frame job buys it at every opening.
• The band separates paint-grade finger-jointed pine from a stain-grade hardwood matched to existing trim. Matching an old profile is the top of the band and sometimes it means having knives ground.
• Trim is bought nationally, so no regional adjustment on this line.

Drywall return repair: board, corner bead, tape and compoundestimated, ±56%

• Some houses finish the inside of a window with wrapped drywall instead of wood casing. A full-frame replacement destroys that return at every opening, and it has to be rebuilt rather than trimmed.
• Board, metal or vinyl corner bead, tape and compound. Materials only; the hours and the drying time between coats are on the line below.
• This is zero on an insert installation, because an insert never disturbs the return. It is one of the clearest examples of how the same ten windows can be two different jobs.
• Board and compound are national commodities, so no regional adjustment on this line.

Rotted sill and jamb repair: framing lumber, sill stock and fastenersestimated, ±58%

• Only a full-frame replacement can find this, and only a full-frame replacement can fix it. When the old frame comes out and the sill under it is soft, the choice is to replace the timber or to bolt a new window onto rot.
• Materials only: treated sill stock, framing lumber to sister or replace a damaged jamb or cripple, and the fasteners. Structural work beyond the opening itself is not in here and not in this calculator.
• The band covers a soft sill nose at the bottom and a full sill plus a jamb leg at the top. Anything worse than that is a framing repair, and it needs looking at rather than budgeting from a web page.
• Lumber is priced nationally here and carries no regional adjustment; the hours to fit it do.

Lead-safe work practice materials: sheeting, tack pads, HEPA filters, suits, signage and waste bagsestimated, ±57%

• EPA states that the federal government banned the sale of lead-based paint for use in homes in 1978, and that approximately three-quarters of US homes built before then still contain some of it. A window is where that paint was worked hardest: sashes rub, stops get pried, and the friction surfaces are exactly where the dust comes from.
• Under the RRP Rule, anyone paid to perform work that disturbs paint in pre-1978 housing must be certified in lead-safe work practices. This is routine, legal, everyday work by a certified renovator — it is not abatement, and this line is not an abatement budget.
• Materials only, per opening: plastic sheeting and tape for the containment, a tacky mat at the doorway, HEPA vacuum filters, disposable suits, wet wipes, warning signs and the bags the debris leaves in.
• EPA also states that in general the RRP Rule does not apply to homeowners doing these projects in their own pre-1978 homes. That is a fact about who the rule covers, not a suggestion about what anyone should do with lead paint.
• Consumables bought nationally, so no regional adjustment on this line. The time to build and strike the containment is the line below.

Certified renovator: set up containment, work wet, HEPA-vacuum and verify the clean-up

• About fifty minutes per standard-size opening on an insert job and an hour and a half on a full-frame one, both scaled by the size factor: hang and tape the sheeting inside and out, keep the surfaces wet while the stops and sashes come out, HEPA-vacuum the work area, and run the cleaning verification before the containment comes down.
• The full-frame figure is higher for a physical reason, not a paperwork one: taking the whole frame out disturbs far more painted surface, inside and outside the wall, than pulling the sashes out of it.
• Priced at the carpenter wage for your metropolitan area, because the certified renovator on a window job is the carpenter doing the work, not an extra person standing next to them. The wage is official BLS data; the hours are our estimate.
• These hours are what a certified crew actually costs over an uncertified one. A quote that is cheaper because nobody is certified is not the same product, and on a pre-1978 house it is not the legal one either.

Glazier: remove the old window, set the new unit, shim, fasten, insulate and seal

• Two hours per standard-size opening for an insert and four and a half for a full-frame replacement. That gap is the honest shape of this job: the same window, in the same hole, with the cladding and the interior either untouched or completely opened. Both figures are then multiplied by the size factor, so the hours you see are not the hours in this sentence unless your openings are standard.
• The insert figure covers pulling the stops and sashes, cleaning out the pocket, dry-fitting, shimming the unit square and plumb, screwing it off, foaming the perimeter and sealing the outside. It also depends on what is coming out: a wood frame empties with a chisel, an aluminium one has to be unscrewed and cut free of the cladding, and a steel casement is cut out in pieces with a reciprocating saw. Those three cases carry factors of 1, 1.3 and 1.9 on the insert hours, and they are our estimate.
• The full-frame figure adds cutting the cladding back, taking the whole frame and the old flashing out, setting a sill pan, flashing the rough opening in the right order and lapping the housewrap over the head. None of that exists on an insert. What the old frame is made of barely moves the full-frame hours, because it is coming out whole either way, so the existing-window factor is not applied there.
• This is the answer to "what does a big-box store charge to fit a window": we do not publish retailer prices because we have no source for them. What we publish is an hourly wage from official BLS data, adjusted to your metropolitan area, which is a figure any quote can be measured against.
• What that wage IS depends on where you live, and this page will not pretend otherwise. BLS publishes a glazier wage (SOC 47-2121) for 194 of the 530 metropolitan and non-metropolitan areas in our index. Where it exists, that is the wage used. In the other 336 areas — Atlanta among them — there is no published glazier figure and the calculation falls back to the construction and extraction group as a whole (47-0000) for that same area. The result is still local; it is just local by sector rather than by trade, and the page says which one you are looking at.
• The hours are ours, not the BLS’s. BLS publishes what people are paid, never how long a job takes, and any page that presents a labour total as official data is combining an official number with an unofficial one and labelling the pair official.
• Squareness is the whole trade here. A replacement window shimmed out of square binds, and it will bind for the twenty years it is in the wall.

Carpenter: bend and fit the aluminium capping on the brake

• Three quarters of an hour for the first standard-size opening: measure the existing frame, work out the bends, set the brake to the profile the house actually has, fit the cap, nail it and seal the top edge so water runs over the cap and not behind it.
• The openings after the first are quicker and the model says so: about twenty-seven minutes each. Once the profile is worked out and the brake is set, ten identical windows on the same house are not ten first windows. A model that charges the setup ten times is charging for a decision that was made once.
• This is exterior trim work rather than glazing, so it is priced at the carpenter wage (SOC 47-2031). That is also the more honest regional figure: BLS publishes carpenters in 526 of the 530 areas in our index against 194 for glaziers, so this line is almost always adjusted by its own trade rather than by a fallback.
• It is bench work at the truck as much as work at the window, and it is the part of an insert installation that a homeowner cannot judge from the ground once it is done.
• Metro-adjusted wage from official BLS data; the hours are our estimate.

Carpenter: cut out the rotted sill or jamb and rebuild the opening

• Two and a half hours per standard-size opening, scaled by the size factor: cut back to sound timber, work out how far the water actually went, splice or replace the sill and any damaged jamb, and get the rough opening square again before the new window goes anywhere near it.
• This is discovered work. It cannot be quoted before the old frame comes out, which is why an honest full-frame quote carries a stated allowance for it rather than a silent one.
• Metro-adjusted wage from official BLS data; the hours are our estimate.

Carpenter: fit the exterior trim, jamb extensions, casing, stool and apron

• Three hours per standard-size opening across both faces of the wall, scaled by the size factor: brickmould and head flashing outside, jamb extensions ripped to the real wall thickness inside, then casing, stool, apron and the caulking that makes the joints disappear.
• Jamb extensions are the slow part and the reason this is carpentry rather than trim work. Walls are rarely the thickness they are supposed to be, and each extension is ripped to the wall it is going into.
• This line is zero on an insert installation, and that single fact is most of why the two methods do not cost the same.
• Metro-adjusted wage from official BLS data; the hours are our estimate.

Drywall installer: rebuild, bead, tape and finish the returns

• Two and a half hours per standard-size opening, and not in one visit: board and bead go on in one, and each coat of compound has to dry before the next. A window return is four outside corners in a square yard, all of them at eye level and all of them lit from the side by the window itself. Larger openings carry the size factor, so the hours shown are higher than that figure unless your openings are standard.
• That side light is why a return that was finished quickly always looks finished quickly. There is no worse place in a house to leave a wavy corner.
• Priced from official BLS data adjusted to your area. Drywall installers (SOC 47-2081) are published in 209 of the 530 areas in our index; in the rest this line falls back to the construction and extraction group for that same area, which the page shows rather than hides. The hours are our estimate.

Primer, finish paint, tape, masking film and painter’s caulkestimated, ±51%

• Every other trade on this page buys materials as well as hours, and the painter was the one exception: the model had painter time against no primer, no paint, no tape and no plastic. That is not a cheaper job, it is a missing line.
• A gallon of bonding primer and a gallon of waterborne enamel, plus tape, masking film, drop cloths and painter’s caulk, covers roughly four or five openings. The band is what that works out to per opening, from a single-colour repaint at the bottom to a stain-grade or custom-tinted finish with more cutting-in at the top.
• The caulk and filler in the interior trim line are the carpenter’s, used to close the joints before anything is painted. This line is the painter’s own materials and they are bought separately.
• Paint and tape are national commodities, so this line carries no regional adjustment; the hours beside it do.

Painter: prime and paint the new interior trim and the patched wall

• Two hours per standard-size opening, scaled by the size factor: prime the bare trim, caulk the joints, two finish coats on the casing and stool, and cut the wall paint back out to a corner rather than stopping where the patch stops.
• New trim arrives primed at best and bare at worst. Either way it is not finished, and a full-frame job that stops at bare casing has not put the room back.
• This is the trade a cheap quote leaves to the homeowner, which is a legitimate saving if you own a brush and a legitimate surprise if you do not.
• Metro-adjusted wage from official BLS data; the hours are our estimate.

Staging and fall protection for openings above the first floor: plank, jacks, anchors and harnessestimated, ±58%

• Sealing and capping the outside of an upstairs window is work at height, and federal law puts a duty of fall protection on construction work at height. OSHA’s general construction rule states that each employee on a walking or working surface with an unprotected side or edge six feet or more above a lower level is protected from falling. Exactly which standard governs a given setup depends on what the setup is — scaffolds, for instance, are covered by their own subpart with its own trigger height — and that determination belongs to the contractor and their competent person, not to a cost page. What is not in doubt is that this equipment is required and has to be paid for.
• The rental or amortised cost of what makes that possible: staging plank, ladder or pump jacks, roof anchors, a harness and a lanyard. Priced per rig-up rather than per window, with a fresh lot allowed for every eight upstairs openings, because that is roughly how far one setup reaches before it is struck, moved and rebuilt.
• The band separates ladder jacks on a two-storey house with flat ground at the bottom from pipe staging on a steep or landscaped lot where the ladder has nowhere level to stand. Weekly hire of tube-and-clamp staging for a two-storey elevation runs into the high hundreds in 2026 before delivery, which is what sets the top of this band.
• This is the line that quietly disappears from the cheapest quote on the pile, and its absence is not a discount: it means someone is planning to work off a ladder with a caulk gun in one hand.
• Equipment hire is priced nationally here and carries no regional adjustment; the hours to set it up and move it do.

Glazier: set up, move and strike the staging

• Two hours to rig it and half an hour for every opening ABOVE THE FIRST FLOOR that it has to be moved to. Staging is set once and then walked along the wall, which is why part of this is fixed and part is per window.
• The count that drives this line is how many openings are upstairs, not how many openings the job has. The model used to charge half an hour of staging for every window in the house, ground floor included, which on a large house was hours of scaffold time for windows a man can reach standing on the lawn.
• It is also why replacing every upstairs window at once is genuinely cheaper per window than replacing two now and three next year: the rigging is paid for once either way.
• Priced from official BLS data adjusted to your area. Where BLS publishes a glazier wage for your area — 194 of the 530 areas in our index — that is the wage; where it does not, the figure falls back to the construction and extraction group for that same area.

Landfill or transfer-station tipping fee for the old windows and trimestimated, ±50%

• The gate fee for what comes out. This used to be one flat figure per opening that never moved, and it was wrong in both directions: an insert produces sashes and stops, while a full-frame tear-out produces whole frames, exterior casing, interior trim and — where there are drywall returns — board and compound as well. Three or four times the volume for the same money is not a band, it is an average pretending to be a price.
• So the count is not the number of openings, it is the number of standard-window-equivalents of debris: the size factor applies, because the glass out of a 32 sq ft unit weighs a bit over twice what a standard one weighs, and a full-frame tear-out counts for three and a half openings instead of one.
• A pre-1978 house does not change this figure, because lead-safe work practice waste from routine renovation is bagged and disposed of as ordinary construction debris. Abatement waste is a different matter and it is not on this page at all.
• Tipping is a local service, and this is the one line on the page where that locality cannot be modelled: there is no national schedule of tipping fees to adjust against, the way there is for wages. So the variation between a municipal transfer station and a lined private landfill sits inside the band instead of inside a multiplier, and it is declared here rather than implied. The haul beside it IS regionally adjusted, through the driver’s hours.

Dump truck and driver: load out and haul the old windows away

• FEMA cost code 8720, a Freightliner M2 class dump truck, at the published federal reimbursement rate. FEMA states explicitly that the operator’s labour is not included in its rates, so the driver’s hours are added separately from BLS wage data rather than hidden inside the machine rate. Adding them on top of a rate that already contained them would count the same labour twice.
• About twenty-five standard-window-equivalents of debris fill one load by volume, and the round trip for a load — load out, drive, tip, return — is two hours. Those two hours are charged as a SHARE, spread across the twenty-five equivalents, plus five minutes of handling for each one. Ten windows out of an insert job do not get a dedicated truck: they go on the next run with the rest of the week’s work, and charging a whole round trip against one broken window would have been the same flat-fee mistake this line was rewritten to remove.
• A roll-off skip on the driveway is the more common arrangement on a domestic job and lands in the same band. It is priced this way because the FEMA schedule is a published federal rate with a URL and a date, and skip hire is not.
• This is the part of disposal that IS regionally adjusted, because the driver is. BLS publishes heavy and tractor-trailer truck drivers (SOC 53-3032) in all 530 areas of our index, so this line never falls back to a sector average.

Not included in this dataset

Lead paint abatement

This calculator prices lead-safe work practices under the RRP Rule: containment, wet work, HEPA vacuuming and cleaning verification by a certified renovator, which is what routine window work in a pre-1978 home legally requires. Abatement — deliberately removing or permanently enclosing lead-based paint — is a different activity with different certification, and it is not budgeted here at any figure. Putting a low number against it would be worse than putting none.

Asbestos-containing glazing compound and caulk

Older glazing putty and window caulk can contain asbestos. Nothing here budgets for testing it or for the licensed work that a positive result triggers. It is a separate job with separate rules and it has to be looked at before anyone starts pulling sashes.

Changing the size or shape of the opening

Enlarging a hole, adding or resizing a header, cutting in a new egress window, or converting a flat window into a bay or bow is structural work. It is not a window replacement, it is a framing job with a window in it, and the price has almost nothing in common with these figures.

Repairing the wall beyond the opening

The sill and jamb repair line covers rot found in the opening itself. Water that has run down inside the wall and reached the sheathing, the band joist or the framing below is a bigger repair and it needs looking at, not estimating from a web page.

Siding, stucco and masonry repair

A full-frame replacement cuts into the cladding. Putting back lap siding around new trim is inside the carpentry here; matching stucco, repairing brick veneer or replacing damaged fibre cement is not, because the cost depends entirely on what the wall is made of and how well anything new can be matched to it.

Permit fees and historic district review

Many jurisdictions require a permit for window replacement, and a house in a historic district may need its window design approved before it can be ordered. Fees and review timelines vary by jurisdiction with no national source, so they are excluded and declared rather than averaged into a number that would be wrong everywhere.

Federal tax credits

These figures are gross costs and nothing is netted off them. The IRS states that the Energy Efficient Home Improvement Credit could be claimed for improvements made through December 31, 2025 — so for work carried out in 2026 that credit no longer applies. That is a published fact about a date, not tax advice; what your own return should say is a question for a tax professional.

Seasonal pricing

People ask what time of year windows are cheapest and we are not going to invent an answer: there is no publishable source for seasonal window pricing, so this model carries no seasonal factor at all. What is real, and is on the product data sheet of every can, is that foams and sealants have a minimum application temperature, and that a winter installation leaves the opening open to the cold while the work happens. That is a constraint on how the job is done, not a discount.

Retailer and national-brand installed pricing

We do not publish what a big-box chain or a national brand charges for a fitted window, because we have no source we can cite for it and a number without a source is a guess with a logo on it. What this page gives instead is the labour at an official BLS wage adjusted to your own area — the glazier wage where BLS publishes one, which is 194 of the 530 areas in our index, and the construction and extraction group for your area where it does not. That is the figure any quote can be measured against, and the page tells you which of the two you are looking at.

Impact-rated and hurricane glazing

Coastal jurisdictions require windows tested for wind-borne debris, and that is a substantial per-window upcharge on top of everything on this page. It is excluded rather than averaged in because it applies to a minority of the country and folding it into a national figure would make every inland answer wrong. Whether your address is inside such a zone is set by your local building department, and it is the first call to make before ordering anything.

Measuring and site survey before the order

Somebody has to measure every opening individually before anything is ordered, because rough openings in the same wall are rarely the same size. That hour or two is inside the contractor overhead applied to this estimate rather than shown as its own line, and it is named here so it is clear it was not forgotten. What it buys is the difference between ten windows that fit and ten windows that have to go back.

Interior window treatments

Blinds, shades, shutters and curtain hardware come off before the work and rarely go back on unchanged, because a replacement window sits at a different depth in the opening. Refitting or replacing them is separate work.

Energy savings

What new windows save depends on the house they go into, the equipment that heats and cools it, the local climate and the price of the fuel. This page prices the work; it does not model a payback, because a payback figure that ignores any of those things is not a calculation, it is a sales aid.
