Interior Renovation Calculators
Drywall goes up, insulation goes in before it, and flooring goes down — all three bought by area rather than volume, no depth, no density, just a room's or attic's square footage converted into a sheet, bag, box, or tile count. This hub covers what an interior renovation puts inside the walls and over the surfaces of a home: drywall for walls and ceilings, insulation for what goes into the cavity behind it, and flooring — laminate, luxury vinyl plank, hardwood, and tile — for what goes underfoot. Paint has its own calculators for coats, coverage ranges, and primer; see the Paint Calculators hub for those.
