How It Works

What the Estimate Includes

The calculator uses the room's centre-line wall perimeter, deducts the area of doors and windows, accounts for wall thickness, and then adds your selected wastage allowance.

Estimating a complete house?

Rooms can share walls, so adding separate room totals may count some walls twice. For a complete home or commercial project, request an itemized BOQ from our team.
