Drywall installation cost dataset
This is the complete dataset behind the drywall calculator, at national rates. Its central claim is a geometric one rather than a price: a house holds three to five times its floor area in board, and until you know which, no price per square foot means anything. The table below is that conversion, worked out for eight house sizes. Last reviewed 2026-08-23.
Board area by house size
National figures. Single storey, rectangular footprint, eight-foot ceilings, typical partition density, ceilings boarded, finished to a level 4.
| Floor area | Board | Multiplier | Sheets | Trade hours | Cost | Per sq ft of board |
|---|---|---|---|---|---|---|
| 800 sq ft | 4,149 | 5.19× | 146 | 93 | $11,754 | $2.83 |
| 1,000 sq ft | 4,744 | 4.74× | 167 | 105 | $13,318 | $2.81 |
| 1,200 sq ft | 5,301 | 4.42× | 186 | 118 | $14,863 | $2.80 |
| 1,500 sq ft | 6,085 | 4.06× | 213 | 135 | $16,970 | $2.79 |
| 1,800 sq ft | 6,823 | 3.79× | 239 | 151 | $18,966 | $2.78 |
| 2,000 sq ft | 7,295 | 3.65× | 256 | 161 | $20,237 | $2.77 |
| 2,500 sq ft | 8,420 | 3.37× | 295 | 187 | $23,364 | $2.77 |
| 3,000 sq ft | 9,485 | 3.16× | 332 | 211 | $26,283 | $2.77 |
Two things are worth reading off that table. The multiplier falls as the house grows, because floor area rises with the square of a dimension while the perimeter rises linearly — so a big house has proportionally less exterior wall to board. And the last column barely moves. That is the finding: the price per square foot of board is nearly constant while the price per square foot of floor is not, which is why quotes should be compared in board area and almost never are.
Finish levels
Finishing hours per square foot of board, and what each level costs on the default 1,500 square foot house. The levels are an industry standard defined by trade associations; the hours are our estimate.
| Level | Hours per sq ft | On a 1,500 sq ft house | What it is |
|---|---|---|---|
| Level 3 | 0.007 | $15,886$-1,084 | Tape and two coats over fasteners and joints, no skim. Acceptable under a heavy texture, and visible under anything else. |
| Level 4 (residential standard) | 0.010 | $16,970 | Tape and three coats, sanded. What almost every residential quote assumes, and what looks right under a flat paint in ordinary light. |
| Level 5 (skim coat) | 0.016 | $19,195+$2,225 | A thin coat over the whole surface, not just the joints. Needed under a satin or gloss paint, or where morning sun rakes across a wall. About 60% more finishing time. |
Sheet size and waste
| Sheet | Coverage | Trade-off |
|---|---|---|
| 4 × 8 ft sheets | 32 sq ft | Two people can carry one up a stair. More sheets and therefore more joints to tape, which is more finishing. |
| 4 × 12 ft sheets | 48 sq ft | Fewer joints on a long wall, which means less taping and a flatter result. Heavy, awkward and not going round a tight staircase. |
Every quantity here carries a 12% waste allowance, which is our estimate of normal offcut loss. It is not padding: board is cut around every opening and every sheet ends somewhere, and the offcuts from a window are rarely big enough to use elsewhere. The default job in this dataset is 6,085 square feet of board, which is 213 sheets after that allowance.
Partition density
Internal walls are boarded on both faces, so they carry twice their own area. This is the assumption most responsible for the spread between the multipliers above, and it is our estimate: linear feet of partition per foot of exterior perimeter.
| Layout | Factor | What it looks like |
|---|---|---|
| Open plan | ×0.8 | Few interior walls: a great room, a couple of bedrooms. Least partition to board, and it shows. |
| Typical layout | ×1.3 | Bedrooms, bathrooms, hallways and closets in the usual proportions. This is the baseline. |
| Many small rooms | ×1.9 | An older layout, or a house with a lot of closets and corridors. Every partition is boarded on both faces, so this is where the sheet count runs away. |

The reasoning behind each figure
Written out so a drywall contractor can point at the exact assumption that is wrong.
- Gypsum boardestimated, ±33%
- Sheets are the unit the trade buys in, and the count comes out of the geometry: total board area plus 12% for cutting, divided by 32 square feet for a 4 × 8 sheet or 48 for a 4 × 12.
- The band covers half-inch standard board at the bottom and five-eighths fire-rated at the top, which is what a garage ceiling under living space and most multi-family work require.
- Gypsum board is heavy and low-value, so its delivered price is mostly haulage: the same sheet costs meaningfully different money near a plant and far from one.
- Moisture-resistant board upchargeestimated, ±43%
- The extra over standard board in bathrooms, laundries and behind a kitchen sink, modelled at 12% of the sheets — which is about what those rooms come to in an ordinary house.
- Worth knowing that moisture-resistant board is not waterproof board. Behind a shower it is the wrong product entirely: that wants a cement or foam tile backer, which is not modelled here.
- Joint compound, tape and fastenersestimated, ±40%
- Compound, paper or mesh tape and screws, priced over the board area rather than the sheet count, because compound is consumed by joint length and joint length follows area.
- A level 5 finish uses noticeably more compound than a level 4, since it skims the whole surface rather than the joints. That is inside the band rather than modelled as a separate line.
- Corner bead and trimestimated, ±45%
- Metal or paper-faced bead on every outside corner and at every window and door return. Modelled at 0.35 linear feet per square foot of board, which is what a normal layout comes to.
- It is the detail that decides whether a room looks straight. A bead set out of true is visible from across the room and cannot be corrected with paint.
- Texture materialestimated, ±52%
- Spray or hand-applied texture. Cheap as a material and not cheap as a decision: a textured wall is much harder to patch invisibly later, because matching an existing texture is a skill in itself.
- Texture also lets a lower finish level pass, which is exactly why builders use it. That is not dishonest, but it is worth knowing that a textured level 3 and a smooth level 5 are very different specifications sold under the same word, "finished".
- Drywall installer: hang the board
- Four hours of set-up plus 0.009 hours per square foot of wall and 0.014 per square foot of ceiling — about three and a half sheets an hour for one pair of hands, which is what a two-person crew hanging sixty sheets a day works out at. Ceilings are slower and it is not close: every sheet is held overhead while it is screwed off.
- Larger sheets hang slightly faster per square foot on a long wall and slower in a cut-up layout, which is inside the rate rather than modelled separately.
- ⚠️ The wage is official BLS data adjusted to your area, with the caveat this page will not hide: BLS publishes drywall and ceiling tile installers for only 209 of the 530 areas in our index, so across most of the country this hour is priced from the broader construction group for your own area. The hours are our estimate either way.
- Drywall finisher: tape, coat and sand
- Three hours of set-up plus a per-square-foot rate that depends entirely on the finish level: 0.007 hours at level 3, 0.010 at level 4 and 0.016 at level 5. Ceiling area is charged at 1.25× because a ceiling shows every defect under its own light.
- This is the line where a cheap quote and an expensive one actually differ. Board is board; what you are buying is coats and sanding, and there is no way to tell from the invoice unless the level is written on it.
- It is also several days rather than one, because each coat has to dry before the next. Anyone promising board and finish in a day is promising a level 3.
- Drywall finisher: apply the texture
- One hour per 220 square feet plus two hours to mask and set up the sprayer. A hand-applied texture such as a knockdown or a skip trowel is slower and sits at the top of that.
- The wage is official BLS data adjusted to your area; the hours are our estimate.
- Labourer: strip out the old board
- One hour per 110 square feet plus three hours of set-up and protection. Pulling board is quick; pulling the several hundred screws or nails it was fixed with, and getting it out of the house, is not.
- ⚠️ In a house built before 1978, stripping painted board disturbs paint, and paid work that does so has to be done by an EPA lead-safe certified firm under the Renovation, Repair and Painting rule. That is a real change to how the job runs, and it is priced on the line below.
- Lead-safe containment, cleaning and verificationestimated, ±46%
- Plastic containment, HEPA vacuuming, wet cleaning and the cleaning verification the rule requires, on a pre-1978 house where old painted board is being removed.
- This is routine regulated work done by a certified renovator, and it is not the same thing as lead abatement — abatement is the permanent removal of a lead hazard, it is a separate licensed specialty, and nothing on this page prices it.
- EPA also publishes that roughly three quarters of United States homes built before 1978 still contain some lead-based paint, which is why the rule is written by date rather than by test result.
- Skip and disposalestimated, ±47%
- Offcuts on a new installation, and the old board as well where it is being stripped out. Gypsum is heavy and it is charged by weight at the transfer station.
- Some jurisdictions will not take gypsum in ordinary construction waste at all, because it produces hydrogen sulphide in a wet landfill. Where that applies it goes to a separate facility, which is at the top of the band.
- Delivery and stockingestimated, ±49%
- Boom-truck delivery and carrying the sheets into the rooms where they will be hung. A 4 × 12 sheet of five-eighths board is around 95 pounds, which is why stocking is a priced service rather than something the crew does on the way in.
- Getting sheets to an upper floor without a boom lift adds real time, and a house with a tight stair is the case where 4 × 8 sheets win despite the extra joints.
Not included in this dataset
- Priming and painting
- A finished drywall surface is bare board and compound, and it must be primed before paint. Painting is a separate trade with its own quote, and the level of finish above is what decides how much work the painter has to do to make it look right.
- Framing, insulation and anything behind the board
- This prices hanging and finishing on studs that already exist. Framing, insulation, vapour barriers, and running electrics or plumbing in the wall all happen before the board goes on and are priced separately.
- Tile backer behind a shower
- Moisture-resistant board is not waterproof board. Behind a shower or a tub surround the correct product is a cement or foam backer with its own waterproofing, and using green board there is a mistake that shows up as a soft wall in a few years.
- Lead paint abatement
- The lead-safe line above is routine regulated renovation work by a certified firm. Abatement — permanently removing a lead hazard — is a separate licensed specialty priced after an inspection, and putting a cheap number on it would be worse than putting none.
- Imported drywall problems
- Between roughly 2001 and 2009 some imported board emitted sulphur compounds that corroded wiring and fixtures. CPSC identified the manufacturers involved. If a house of that vintage has blackened copper and a persistent smell, that is an investigation rather than a drywall quote.
- Permits
- Boarding out existing framing rarely needs one. Anything that changes the framing, or fire-rated assemblies between a garage and living space, usually does. Fees vary with no national source.
