Drywall estimating software is bought by a hanging and finishing contractor whose bids are lost or won on the board count and the finish level. The takeoff is wall and ceiling area from the plan, divided by the board size and rounded up per room with a waste allowance for cuts; mud, tape, corner bead, screws and adhesive follow from the board count; the hours are hanging per board and finishing per square foot at the level the specification asks for, from the crew's own record. Priced at the supplier's sheet and a loaded rate, with the lift as equipment, then overhead and markup, the bid is a number the crew can meet, and the estimate template on this site prints its lines.
Boards from the area, by room and by board size
Count each room's wall and ceiling area from the plan, choose the board length that minimises butt joints, and round up per room rather than across the job, because the offcuts from one room rarely fit the next. Add a waste allowance the crew has measured on its own jobs; openings are counted as board because the cut-out is waste too. Software that scales the plan does the areas; the estimator chooses the board sizes and the waste.
Mud, tape and accessories follow the boards
Joint compound by the bucket or bag, tape by the roll, corner bead by the length of outside corners, screws by the board and adhesive by the tube all scale from the board count and the finish level; a level five finish takes more compound and more hours than a level three. Fasteners and consumables are small money but a real line, and the estimate should carry them rather than bury them in the markup.
Hang and finish hours, the lift and the price
Hanging is priced per board from the crew's record for that ceiling height and board size; finishing is priced per square foot by level. Load the hourly rate with taxes, insurance and the van, charge the lift and the scaffold by the day, add any subcontracted texture or insulation at quote, then the overhead percentage and the markup. Pro keeps every estimate against the customer and the job with the board count, so the boards bought and the boards hung can be read together when the job closes.
Questions people ask about drywall estimating software
How is drywall estimated?
Boards from wall and ceiling area per room with waste, mud, tape and accessories from the board count, hanging hours per board and finishing hours per square foot by level, at a loaded rate, plus equipment, overhead and markup.
Should openings be deducted from the drywall area?
Small openings are usually not deducted, because the cut-out becomes waste; large openings such as garage doors are deducted and the waste allowance covers the rest.
Does the finish level change the estimate?
Yes. A higher finish level takes more compound, more coats and more hours per square foot, and the bid should name the level it is priced at.
