Pro Tip: For 8-foot ceilings, use 4×8 sheets hung horizontally. For 9 or 10-foot ceilings, 4×12 sheets hung horizontally minimize joints. Fewer joints = less taping = faster finish = higher profit.

Pricing Drywall Jobs as a Contractor

  • Hang only: $0.75–$1.25/sq ft
  • Tape & finish only: $0.75–$1.50/sq ft
  • Hang + tape + finish: $1.50–$3.00/sq ft
  • Level 5 finish (skim coat): add $0.50–$1.00/sq ft
  • Texture (knockdown, orange peel): add $0.30–$0.75/sq ft

A standard 12×12 room (walls + ceiling ≈ 528 sq ft) should take 1 person about 2 days to hang and 3 days to tape/finish (waiting for mud to dry between coats). Price accordingly — if you're fast, you make more per hour.
