Interior painting: walls, ceilings, trim and doors
The core of the work. Furniture centred and covered, floors protected wall to wall, hardware and switch plates removed rather than cut around, holes and cracks filled and sanded flush, water stains sealed with a stain-blocking primer so they do not ghost through, bare filler spot-primed, then two finish coats cut and rolled. On older Ottawa plaster we test for adhesion and chalking before committing to a topcoat, because a premium paint applied over a failing substrate fails with the substrate. In newer Barrhaven, Kanata and Riverside South builds the usual issue is the opposite: a single thin builder coat over unprimed drywall that soaks up the first coat unevenly and needs a sealing primer to level the porosity.
Indicative range: about $2 to $4 per square foot of wall area for walls only, rising to roughly $3 to $6 per square foot once ceilings and trim are included. By room, published Ottawa guides put a standard bedroom at $400 to $800, a larger primary bedroom at $600 to $1,200 and a living or family room at $800 to $1,600. A whole-home interior repaint commonly lands between $4,000 and $8,000, and a fully scoped two-thousand-square-foot Ontario home covering walls, ceilings, trim and doors is published between $8,000 and $14,000 including HST. Ceilings add roughly $1 to $3 per square foot; trim, baseboards and casings run about $1.50 to $4 per linear foot.
