How to estimate a drywall job?
Short answerMeasure the wall and ceiling area, divide by the area of one sheet to get the count, and add waste. Then add screws, tape, joint compound, corner bead and primer, and price labor by stage: hang, tape, mud, sand. Include ceiling height and layout, since high ceilings and many cuts slow the crew.
The explanation
Start with area. Measure each room's wall lengths and heights, add ceilings, and subtract large openings. Convert to sheets using the sheet size you stock, commonly four by eight or four by twelve feet. Round up per room and add a waste allowance for cuts.
Next, list the supplies that scale with the job: screws, paper or mesh tape, joint compound in the weights you buy, corner bead and sanding supplies. Compound is often underestimated, since three coats plus a skim add up on larger jobs.
Then price labor in stages, because each stage has a different pace and a drying gap between coats. Note ceiling height, number of corners, texture matching and access. Write the scope with finish level, and state whether paint, patching of old walls and cleanup are included.
Steps
- Measure each room's walls and ceilings and subtract large openings.
- Convert the area to sheets and add a waste allowance.
- List screws, tape, compound, corner bead and sanding supplies.
- Price hang, tape, mud and sand as separate labor stages.
- Write the finish level and exclusions in the scope.
What to watch for
- Underestimating compound for multiple coats.
- Ignoring ceiling height and complex layouts.
In drywall contractor
Drywall runs in stages with drying time between coats, so one job occupies the crew across several visits. The estimate should show hang, tape, mud and sand so the customer understands the calendar. All drywall contractor scheduling questions.
