How Much Does Drywall Installation Cost in 2026?
Drywall material runs $0.40–$0.65 per square foot — genuinely cheap. The finishing (tape, mud, sand, prime) typically costs 2-3x the board itself, which is why professional installed quotes land at $1.50–$3.50 per square foot.
The material side
A standard 4×8 sheet of 1/2" drywall runs $12–$18; 5/8" fire-rated runs a bit more. For a 500 sq ft room (walls + ceiling), that's roughly 18 sheets — call it $250–$350 in board alone. Our drywall calculator sizes sheets, screws, and joint compound from your room dimensions.
Why finishing costs more than the board
Hanging drywall is mechanically simple; finishing it to an invisible, paint-ready surface is a genuine skill that takes practice to do without visible seams or sanding marks under raking light. Professional tapers charge accordingly — this is the part of the job where hiring out often makes sense even for otherwise-confident DIYers.
The DIY reality
Hanging: very doable for a first-timer with a helper. Finishing to a flawless level-5 finish: expect your first attempt to show some imperfection under certain lighting — acceptable for a garage or utility room, less so for a formal living space. A middle path: hire out just the finishing, DIY the hang, and split the savings.
