Paint is the cheapest transformation in renovation: a few hundred dollars and a weekend can make a dated room look new. Professionally painted, Ontario interiors in 2026 typically cost $300–$800 per room or $2–$6 per square foot of floor area, with whole-house repaints of a 2,000 sq ft home running $4,000–$10,000.
Painters charge for prep as much as for paint — patching, caulking, taping and priming decide the finish far more than the brand in the can. Figures below are NorthPeak planning estimates for professional work including standard prep and two coats.
Cost by room and project size
| Project | Typical range | What affects it |
|---|---|---|
| Bedroom / office | $300–$600 | Wall condition, ceiling included or not |
| Living room / open concept | $500–$1,000 | High ceilings, stairwells, cut-in work |
| Kitchen / bathroom | $400–$800 | Cabinet-adjacent masking, moisture-resistant paint |
| Whole house (2,000 sq ft) | $4,000–$10,000 | Colour changes need extra coats; dark-to-light is pricier |
Why quotes vary so much
- Prep is the job: filling, sanding, caulking and priming can be half the labour. A painter who quotes without looking at the walls is guessing.
- Paint grade ($30–$70 per gallon): premium paints cover in two coats; cheap paint can need three, erasing the savings in labour.
- Ceilings, trim and doors: often quoted separately — ceilings $1–$2/sq ft, trim $4–$8 per linear foot.
- Colour changes: going from dark to light (or to bold colours) typically needs a primer coat plus two finish coats.
- Ontario labour rates: painters run roughly $30–$60/hour; GTA crews trend higher.
DIY vs. hiring: the honest math
A DIY room costs $80–$200 in paint and supplies versus $300–$800 hired — a real saving if your time is flexible. But professional crews paint a room in a day; DIY takes a weekend per room once you count prep, drying time and cleanup. DIY wins for single rooms with good wall condition. Hire out for whole houses, stairwells, high ceilings, and anything involving plaster repair or wallpaper removal.
Quote tip: always ask whether the quote includes ceilings, trim, the number of coats, and the specific paint brand and line. Two quotes at the same price can describe very different jobs.
