Whole-house finishing estimator
List your rooms once and get one shopping list.
Board, compound, tape, screws and paint for every room in one roll-up, with a priced total if you enter what you pay.
Example: a small two-bed flat
Four spaces listed at their real sizes, walls and ceilings, openings deducted. This is what the roll-up produces:
Why a roll-up beats estimating room by room
Rounding up per room is the expensive habit: four rooms each rounded up to the next whole bucket can add two buckets you did not need. The roll-up adds the areas first and rounds once, which is what a contractor's takeoff does. The saving on a whole house is usually one to two buckets of compound and a couple of sheets.
The other reason is the shopping trip. Buying board, mud, tape, screws and paint in one order means one delivery, one batch of mud, and one colour batch for the paint. Mixing batches mid-job is how a wall ends up with a visible band in it.
What this does not include
Corner bead, which is priced by the linear foot of external corner; setting-type compound for the first coat, which some finishers prefer; sanding sheets and poles; plastic sheeting and tape for dust control; and any labour. It also assumes rectangular rooms with flat ceilings: a vaulted ceiling or a bay window needs measuring by hand.
