How Do I Estimate Drywall Installation?
Estimating drywall installation costs is essential for budgeting your home renovation or new construction project. Whether you’re hiring a contractor or planning a DIY installation, knowing the materials, labor, and additional expenses involved can help you accurately estimate the total cost.
Step 1: Measure the Area
Start by calculating the total square footage of the walls and ceilings where drywall will be installed.
🔹 Formula:
Length × Height = Square Footage (per wall)
Add up all walls and ceilings for total square footage.
For example, if a room is 12 ft. x 10 ft. with 8-foot ceilings:
- Each wall: 12 × 8 = 96 sq. ft.
- Two walls: 96 × 2 = 192 sq. ft.
- Other two walls: 10 × 8 = 80 sq. ft.
- Two walls: 80 × 2 = 160 sq. ft.
- Ceiling: 12 × 10 = 120 sq. ft.
Total drywall needed: 192 + 160 + 120 = 472 sq. ft.
Step 2: Calculate Drywall Sheets Needed
Standard drywall sheets come in 4×8 ft. (32 sq. ft.), 4×12 ft. (48 sq. ft.), and other sizes.
🔹 Formula:
Total Square Footage ÷ Drywall Sheet Size = Number of Sheets Needed
For 472 sq. ft. with 4×8 ft. (32 sq. ft.) sheets:
472 ÷ 32 = 15 sheets (round up to 16 for waste).
Step 3: Estimate Material Costs
💰 Drywall Sheets: $10–$20 each (16 sheets = $160–$320)
💰 Joint Compound & Tape: $20–$50
💰 Screws & Fasteners: $10–$30
💰 Sandpaper & Tools: $20–$50
🔹 Total DIY Material Cost: $200–$450 per room
Step 4: Estimate Labor Costs
If hiring a contractor, labor costs typically range from $1.50–$3.50 per sq. ft.
💰 For 472 sq. ft.:
- Low-end: 472 × $1.50 = $708
- High-end: 472 × $3.50 = $1,652
🔹 Total Cost with Labor: $900–$2,000 per room
