FAQs — Drywall Cost in New Hampshire
How many sheets of drywall do I need for a 12x12 room?
A 12×12 room with 8-ft ceilings has roughly 384 sq ft of wall surface. Deducting one door and two windows, you need about 11–12 sheets of 4×8 drywall (32 sq ft each), plus 10% waste.
How much does drywall installation cost per square foot?
Professional drywall installation (hanging, taping, finishing, and sanding) typically costs $1.80–$3.50 per square foot. A standard 12×12 room costs roughly $800–$1,400 labor-only.
What thickness of drywall should I use?
1/2 inch (12.7mm) drywall is standard for most walls and ceilings. Use 5/8 inch for fire-rated walls, ceilings under heavy loads, or where soundproofing matters. Use 3/8 inch only for curved surfaces.
Can I hang drywall myself?
Yes — hanging is the easiest part. The hard part is taping and finishing (mudding). A DIY job can save $1–$2 per sq ft in labor, but achieving a smooth finish takes practice.
