Drywall Installation Cost Calculator

A full drywall installation — hanging the board plus taping, mudding, and sanding it paint-ready — typically runs $1.50 to $3.50 per square foot of drywall surface. A single room with about 500 sq ft of surface lands around $1,000 to $1,750, and a whole house is much more. The finish level is the biggest driver (Level 3 cheapest, Level 5 with a full skim coat priciest), then ceiling height, and any add-ons like demolition of old walls, insulation, or texture. Enter your area and finish level in the calculator above for a localized number.

Installation is the whole job: hanging (measuring, cutting, and screwing the sheets to the studs and joists) plus finishing (taping the seams, spreading multiple coats of joint compound, sanding smooth, and any texture). Finishing on its own is just that second phase — hired when the board is already hung. Because a full install includes both the hanging labor and the finishing labor, it costs more per square foot than finishing-only. This calculator prices the complete install; if your board is already up, use a finishing-only estimate instead.

Contractors think in square feet of surface even though board is sold in sheets. A standard sheet is 4x8 (32 sq ft) or 4x12 (48 sq ft), and your quote is the total wall-and-ceiling area to be covered multiplied by a per-square-foot rate. Some pros quote per sheet installed, but it converts to the same thing. The calculator uses surface area, so measure the walls and ceilings you want covered; don't subtract normal window and door openings, since the offcuts are waste you still pay for.

They're the Gypsum Association's standard (Levels 0-5) for how smooth and complete the finish is, so you and the installer agree on the result. Level 3 is texture-ready — the right choice under a heavy texture that hides imperfections. Level 4 is the most common for painted walls: sanded smooth for flat or eggshell paint. Level 5 adds a thin skim coat over the entire surface for a flawless, glass-smooth result under critical light or glossy paint. Higher levels take more coats and labor, so they cost more; the calculator lets you pick 3, 4, or 5.

Not by default. The base estimate assumes you're drywalling open framing or over an existing surface. If old drywall or plaster has to come down first, add the Demo Old Drywall option — it covers tearing out the existing wall and is charged per square foot because it's labor plus disposal. On a remodel that's almost always needed; on new construction it isn't. Toggle it in the calculator if your job starts with removal so the estimate reflects the full scope.

It's often the smart move. When the studs are exposed before the board goes up, it's the cheapest, easiest time to add batt insulation for warmth and soundproofing — you'll never have better access. The calculator includes Install Batt Insulation as a per-square-foot add-on so you can see the combined cost. If you're finishing a basement, garage, or building an interior partition for a quieter room, doing insulation and drywall together in one pass saves you from opening the wall again later.

Yes. Ceilings above 8 feet mean scaffolding, lifts, or stilts to reach and hang heavy sheets safely, which slows the crew and raises the risk — so most installers add a surcharge (the calculator applies about 20% for ceilings over 8 ft). Vaulted, stairwell, and two-story spaces are the usual culprits. Enter your actual ceiling height so the estimate accounts for the access; a great room with 12-foot walls costs meaningfully more to hang and finish than a standard 8-foot room of the same footprint.

It's part looks, part cost. Smooth walls read modern and high-end but need a better finish (Level 4 or 5) because nothing hides flaws, so they're more labor. Sprayed texture — orange peel or knockdown — hides minor imperfections and seams, pairs with a cheaper Level 3 finish, and is easy to touch up, which is why builder homes use it. The calculator has a Texture Spraying add-on so you can price it in. If you want the contemporary smooth look, budget for the higher finish level; if you want forgiving and economical, texture over Level 3.

The base install is priced to a paint-ready state — hung, taped, mudded, and sanded — but priming and painting are usually a separate trade. New drywall should be primed before painting so the paint goes on evenly and the seams don't flash a different sheen. The calculator offers a Prime & Paint 1st Coat add-on if you'd like the installer to handle the first coat right after finishing, which is convenient and reveals any spots to touch up. Full painting beyond that first coat is typically quoted by a painter.

Location matters. Standard 1/2-inch board is fine for most walls; ceilings and damp-prone areas want thicker or specialized board. Moisture-resistant 'green board' or 'purple board' belongs in bathrooms, laundry rooms, and basements, and cement board goes behind tile in showers. 5/8-inch 'Type X' fire-rated board is required between a garage and living space and helps with soundproofing. Tell your installer where each wall is so they hang the right product; the calculator prices standard installation, and specialty board can shift material cost.

Longer than people expect — because compound has to dry, not because the labor is slow. A standard room usually spans 3 to 5 days: hang the board on day one, then apply and dry successive coats of mud, sand, and texture over the following days, since each coat has to cure before the next. A whole house runs one to two weeks or more. Humidity and temperature affect drying, higher finish levels need more coats, and demolition or high ceilings add time. Rushing the drying is what causes cracks later, so the schedule is mostly patience.
