Flood-Cut Demolition Take-Off

Drywall area removed, 4x8 sheet count, baseboard linear feet, and batt-insulation area from wall run and cut height.

Run the calculator

Example

You enter

Affected wall run (linear ft) 60
Cut height (in) 24
Two sided false
Insulated true

You get

Drywall removed 120 ft^2
4x8 sheets to replace 4
Baseboard 60 LF
Batt insulation 120 ft^2

Details, formula, and sources

drywall_ft2 = wall_run_lf * (cut_height_in/12) * faces (faces = 2 if both sides); sheets_4x8 = ceil(drywall_ft2 / 32); baseboard_lf = wall_run_lf; insulation_ft2 = insulated ? wall_run_lf * (cut_height_in/12) : 0. 4x8 sheet = 32 ft2.
