Basement Drywall Cost 2026: Sheets, Board Types & Calculator

Drywall in a basement isn't quite the same job as upstairs. Concrete walls sweat, ceilings are full of pipes and ducts, and many codes want fire-rated board near the furnace. Plan for that and the job goes smoothly. In 2026, most homeowners pay $2.00–$3.50 per square foot of board to have basement drywall hung, taped and finished.

Basement drywall cost in 2026

• Materials only: $0.60–$1.00 per sq ft (mold-resistant board costs about 40% more than standard)
• Hang, tape and finish labor: $1.50–$2.50 per sq ft on walls, more on ceilings
• A 750 sq ft basement with ceiling (about 2,000 sq ft of board): roughly $4,500–$7,000 installed
• Soffits around ducts and beams: add $15–$30 per linear foot

Which board to use below grade

• Mold-resistant (paperless or purple board) for all exterior walls — the safe default
• Fire-rated 5/8 in Type X around furnaces, under stairs and where local code asks
• Never set drywall directly on concrete: leave a 1/2 in gap at the floor

How to count sheets

Add up the wall area (perimeter × height), add the ceiling if you're covering it, then add 10–15% for cuts. Divide by 32 for 4x8 sheets or 48 for 4x12 sheets. Plan one 5-gallon bucket of mud for every 450 sq ft.
