Carpenter Bee guide cover: interior painting cost in Ontario

Quick answer

In short

Painting a bedroom in Ontario costs $450 to $800 for walls only, or $700 to $1,300 with the ceiling and trim. A three-bedroom house of 1,800 to 2,200 square feet runs $6,500 to $13,000.

Here is the thing that changes how you read every painting quote: labour is 70 to 85 percent of the cost. A gallon of good paint is $60 to $80. The days of masking, patching, priming and cutting in are the invoice.

Which means the cheapest quote usually is not cheaper paint. It is fewer hours of preparation — and preparation is the part you will be looking at for the next eight years.

Does the grade of paint matter?

It changes how long you go before doing this again.

GradePer gallonTypical life
Builder or contractor grade$38–$553–5 years
Mid-tier premium$60–$806–8 years
Top-tier premium$85–$1158–12 years

On a house needing fifteen gallons, the gap between builder grade and top tier is roughly $750 — against a labour bill of eight thousand. Upgrading the paint is the cheapest decision in the whole project, and the one most likely to be quietly downgraded on a low quote.

What makes one quote higher than another?

  • Coats. Going from a dark colour to a light one needs primer plus two finish coats. That is three passes over every wall instead of two.
  • Ceiling height. Nine-foot ceilings add about 12 percent more wall area than eight-foot, before any scaffolding.
  • Repairs. Patching, sanding and filling before any colour goes on. This is the line that separates a finish that looks new from one that looks painted over.
  • Trim and doors. Slow, fiddly, and often quoted separately. Check whether it is in or out.
  • Furniture and floor protection. Some quotes include moving and covering; some charge for it.

Ceilings and trim: in or out?

This is the single most common reason two painting quotes are not comparable. Walls only is $1.75 to $3.25 per square foot; walls, ceilings and trim is $3.50 to $6.50 — roughly double.

Decide before you call, and tell all three companies the same thing. If you are not sure, ask each of them to price both, which costs them nothing and tells you a lot about how they work.

Red flags in a painting quote

What you seeWhy it mattersWhat to do
No mention of prepPrep is most of the labour and all of the final qualityAsk what patching, sanding and priming is included, in writing
Paint brand and line not namedPaint grade decides whether you repaint in four years or tenAsk for the brand, the product line and the sheen per room
Number of coats not statedOne coat over a colour change looks fine wet and patchy dryAsk for the number of coats to be written into the quote
Ceilings and trim ambiguousIt roughly doubles the price and it is easy to leave vagueGet an explicit yes or no for each, per room
A price far below the othersAlmost always fewer prep hours or thinner paint, not efficiencyAsk what they are doing differently; a good painter will tell you plainly
Cash only, no invoiceNo receipt, no warranty, no recourse if it peelsPay traceably and keep the invoice

What to do next

Walk the rooms and write down two things: which rooms, and whether ceilings and trim are included. Then ask three companies to quote that exact list with the number of coats and the paint line named.

Check each company with our contractor checklist — painters work at height and on ladders, so liability insurance matters — and read your rights on a renovation contract. If painting is the last step of a bigger job, our flooring guide covers the order of work.

Frequently asked questions

Usually yes. Top-tier paint lasts 8 to 12 years against 3 to 5 for builder grade, and on a whole house the upgrade costs a few hundred dollars against a labour bill in the thousands.

Paint first, then floors, then touch up the baseboards. Painters are messier than floor installers, and touching up trim is quicker than protecting a finished floor.

Two finish coats is standard. Changing from a dark colour to a light one needs primer plus two coats, which is a third pass over every surface and shows up in the price.

A three-bedroom home of 1,800 to 2,200 square feet costs roughly $6,500 to $13,000 in 2026, depending on whether ceilings and trim are included and how much repair work the walls need.

Because labour is 70 to 85 percent of the bill. Masking, patching, sanding, priming and cutting in take days, and painters charge $40 to $75 an hour for them.

A standard 10×12 bedroom costs $450 to $800 for walls only, or $700 to $1,300 including the ceiling and trim. Open-concept living and dining areas run $1,400 to $3,200.
