Drywall pricing in 2026 runs $13-$18 per 4x8 sheet of ½-inch standard board, $18-$25 per sheet for moisture-resistant (green board) or Type X (fire-rated). Hang-and-finish labor averages $1.80-$2.80 per sq ft of board for level 4 finish (standard); level 5 (smooth, for flat paint or dramatic lighting) runs $3.50-$5 per sq ft. A typical 500 sq ft room with 8-ft ceilings uses 20-22 sheets.

Level 4 vs Level 5 finish — what you're actually paying for

Level 4 is standard residential — seams taped and mudded, screws filled, corner bead installed, sanded smooth enough for eggshell or satin paint and orange-peel texture. Level 5 adds a full skim coat across the entire wall surface, producing a glass-smooth finish that holds up under flat paint and raking light. Level 5 runs $1.50-$2.50 per sq ft more than Level 4 — worth it in living rooms with large windows and hallways with floor lamps where Level 4 flaws become visible.

Sheet types and when each applies

Standard ½-inch for walls and ceilings in dry areas. 5/8-inch Type X (fire-rated) required on garage walls and ceilings that share with living space, around furnaces, and on multi-family party walls. Moisture-resistant green board or cement board for bathroom and shower surrounds. Mold-resistant paper-faced board for basements and damp spaces. High-impact board for rental properties and high-traffic commercial.

DIY vs hiring a drywall crew

Hanging is DIY-friendly with a helper and a T-brace for ceilings. Finishing is where DIY goes wrong — proper 3-coat mudding with correct feathering takes practice, and poor finishing shows up permanently once paint goes on. Hybrid approach: DIY the hang (save $0.80-$1.20 per sq ft), hire a pro taper/finisher ($1.20-$2.00 per sq ft). Most homeowners save 30-40% versus full hire while avoiding the steepest skill curve.

Frequently asked questions

How many sheets of drywall do I need?
Calculate total wall area (perimeter × ceiling height) + ceiling area, subtract window and door openings, divide by 32 (4x8 sheet), and add 10% waste factor. A 12x14 room with 8-ft ceilings: walls 416 sq ft, ceiling 168 sq ft, total 584 sq ft. Minus 40 sq ft for openings = 544 sq ft. Divided by 32 = 17 sheets, plus waste = 19 sheets.
How much does drywall cost per sq ft installed?
2026 pricing: Level 4 finish (standard) $2.80-$4.00 per sq ft installed, Level 5 (smooth) $4.50-$6.00 per sq ft. New construction rough-in tends toward the low end; remodel work with protection, demo, and coordination runs 20-35% higher.
How long does drywall take to finish?
Hanging: 1-2 days for a typical 500 sq ft room. Finishing: 4-5 days with 3 coats of mud (first coat day 1, second day 3, third day 5 with sanding between). Full drywall + paint-ready room: 7-10 days including cure time. Rushing mud coats leads to cracking.
Should I use green board or cement board in bathrooms?
Cement board (Durock, HardieBacker) for any surface behind tile in wet areas — showers, tub surrounds, floor tile substrate. Green board (moisture-resistant drywall) for bathroom walls and ceilings outside wet areas. Standard drywall fails quickly in bathrooms. For high-moisture applications like steam showers, use cement board with waterproof membrane.
What's the warranty on drywall installation?
Workmanship warranty is typically 1 year on most residential jobs. Nail pops, minor crack at corners, and settling cracks within the first year are the installer's responsibility to repair. After year 1, repairs are your cost. The drywall material itself has no warranty — it's considered a commodity.
