Garage door cost dataset

Size against construction

National figures with new springs sized to the door, new weatherseal, the old door taken away and the existing opener reconnected.

The 20 ft column rises more than its width alone would justify, and that is deliberate rather than a rounding artefact: past the standard catalogue the track, the shaft and the springs all step up a grade and the panel needs more reinforcement to span the opening. Size factors are 0.9, 1, 1.72, 1.9 and 2.35 against a 9 × 7 baseline, and they are our estimate.

The weight factor, which is what sizes the springs

This column is why a “door only” price is not a discount. On the default 16 × 7 in insulated steel, carrying the old springs over shows as $2,684 instead of $3,073. The door it was sized for weighed something else, and the difference is made up by the opener, every time the door moves, for as long as it lasts.

When R-value is worth paying for

This is not modelled as a cost, because it does not change what the door costs. It changes whether the upgrade is worth buying, which is a different question and one the industry has no interest in asking.

Uninsulated garage

Bare walls and ceiling, and usually a gap under the door into the house. An insulated door here changes very little, because the heat leaves through everything else.

Partly insulated, or a room above

Insulated ceiling under a bedroom, or insulated walls. This is where the door starts to matter, because it becomes one of the weaker surfaces rather than one of many.

Insulated and heated or cooled

A workshop or a garage that is part of the conditioned envelope. Here the door is a wall, and its R-value earns its money.

Line items

The five door lines are alternatives, never more than one. Everything measured in “door equivalents” is scaled by size and multiplied by the number of doors.

The reasoning behind each figure

Written out so a door installer can point at the exact assumption that is wrong.

Single-layer steel door sectionsestimated, ±38%

• Priced as a 9 × 7 single and then scaled by size: 0.9 for an 8 ft, 1.72 for a 16, 1.9 for an 18 and 2.35 for a 20. The 20 ft step is deliberately more than its width, because past the catalogue sizes the panel needs more reinforcement to span the opening.
• A steel skin with nothing behind it. It dents from the inside if a bicycle falls against it, and every gust of wind is audible in the garage.

Two-layer insulated steel door sectionsestimated, ±38%

• Priced as a 9 × 7 single and scaled by the same size factors. Steel with bonded polystyrene, nominally R-6 to R-9.
• The step up from single layer buys stiffness and quiet more reliably than it buys warmth, and stiffness is what stops a door bowing over its own width.

Three-layer insulated steel door sectionsestimated, ±37%

• Priced as a 9 × 7 single and scaled by the same size factors. Steel, polyurethane, steel — nominally R-12 to R-18.
• It is around three quarters heavier than a single-layer door of the same size, and that weight is the reason its springs have to be sized for it rather than carried over.

Composite or carriage-house door sectionsestimated, ±45%

• Priced as a 9 × 7 single and scaled by the same size factors. An overlay on a steel or composite core, made to read as a pair of hinged carriage doors while working as a sectional one.
• The band is wide because this is where the catalogue stops being about performance and starts being about appearance, and appearance has no ceiling.

Solid wood door sectionsestimated, ±51%

• Priced as a 9 × 7 single and scaled by the same size factors. Real timber, usually built to order, and around two and a half times the weight of a single-layer steel door the same size.
• It also carries a maintenance commitment that the steel doors do not: a south-facing timber door wants refinishing on a cycle, and neglecting that is how it ends up warped rather than merely faded.

Track, hinges, brackets and rollersestimated, ±43%

• Vertical and horizontal track, the hinges between sections, the end and top brackets and the rollers. Scaled by size along with the door, because a wider door needs more of all of them and a heavier one needs a better grade.
• Reusing old track is a false economy that shows within a year, because the track is bent in exactly the places the old door taught it to bend.

Torsion springs sized to the new doorestimated, ±43%

• ⚠️ This is the line that separates a real price from a cheap quote. Springs are a counterweight calculated for the weight of the door they carry, and a new door rarely weighs what the old one did — a three-layer steel door can be close to twice a single-layer one.
• Priced by weight equivalent: the size factor multiplied by the construction weight factor (1 single-layer steel, 1.35 two-layer, 1.75 three-layer, 1.6 composite, 2.4 wood).
• Carrying the old springs over does not make the job cheaper; it makes it a different job, one where the door is out of balance and the opener spends its life making up the difference.

Shaft, cable drums and bearingsestimated, ±44%

• The tube the springs wind onto, the drums the cables wrap around and the bearings at each end. Replaced where the existing shaft is worn, or where the new door is heavy enough to want a better grade.
• On an oversize or a timber door this is not optional in practice, because the shaft that carried a light steel door is undersized for one twice its weight.

Glazed top sectionestimated, ±55%

• A row of lights across the top panel. It is the commonest option taken and the one that adds most to the look of the house from the street.
• It also adds weight at the top of the door, which is where the opener pulls, so it is one more reason the springs are sized to the finished door rather than to the catalogue base.

Bottom, side and top weathersealestimated, ±49%

• The bottom astragal and the stop moulding with its seal down both jambs and across the head. Cheap, and by a distance the best value per dollar on this page for keeping weather and leaves out.
• On an uninsulated garage, sealing the perimeter does more for comfort than the R-value of the panel does, which is the opposite of how doors are sold.

New jambs and header trimestimated, ±54%

• The timber the track and the stop fix to. On a garage where water has run down the opening for years, the bottom foot of both jambs is usually soft, and it is discovered on the day the old door comes off.
• Fixing rotten jambs is not optional if the new track has to bolt to them, which is why it is here rather than in the exclusions.

Door technician: strip out, set track, hang sections, wind and balance

• Four hours for a single and five and a half for a double, plus an hour for a removal, an hour for jamb work and half an hour to reconnect and re-set an existing opener. Multiplied by the number of doors.
• The wage is official BLS data adjusted to your metropolitan area, and this is solid ground: BLS publishes maintenance and repair workers in all 530 areas of our index, so there is no fallback anywhere. The hours are our estimate.
• The hours that matter are at the end, not the beginning. Setting the track plumb and then winding the springs until the door stays put halfway is what separates a door that lasts twenty years from one that binds.

Take the old door awayestimated, ±49%

• Sections, track and hardware to the transfer station. A steel door is largely scrap metal, which is why this line is smaller than the bulk of the thing suggests.
• A timber door is not scrap and costs more to tip, which is inside the band rather than modelled separately.

What a new door does to your resale value

The figure everyone quotes for this comes from a proprietary annual study that we have not read and cannot verify, so we do not repeat it. What we can tell you is what the job costs, which is the half of the equation that is actually knowable.

The opener

This page assumes an existing opener is reconnected and re-set to the new door, which is a half hour of the technician’s time and is included. A new opener is a separate job with its own choices, and it is worth knowing that any operator sold in the United States since 1 January 1993 has had to ship with entrapment protection under the federal standard.

Federal tax credits

The energy efficient home improvement credit could be claimed for improvements made through 31 December 2025, which is what the IRS publishes. Work carried out after that date is not covered by it. We state the published fact and nothing more; what your own return should say is a question for a tax professional.

Structural work on the opening

Widening an opening, replacing a header or repairing the framing around it is construction, not door fitting. The jamb line here replaces the timber the track bolts to and nothing behind it.

Insulating the garage itself

On an uninsulated garage the door is one of several weak surfaces, and upgrading it alone changes less than the marketing suggests. Insulating the ceiling under a room, or sealing the door into the house, is separate work and often the better first dollar.

Permits

Some jurisdictions require a permit for a garage door replacement, particularly in high-wind areas where the door has to meet a pressure rating. Fees vary with no national source and are excluded rather than averaged.

On the tax credit in particular: IRS, Energy Efficient Home Improvement Credit states it could be claimed for improvements made through 31 December 2025. Work after that date is not covered, so any guide still promising a percentage back is out of date. Retrieved 2026-08-22.
