What Affects the Cost of Painting a House in Hamilton?
Two Hamilton houses of the same size can get very different painting quotes. A century home in Kirkendall with plaster walls and decades of old paint needs far more prep than a recent build in Binbrook, even if the paint and the square footage are identical.
Published price ranges are a useful starting point, but they can't see your home. This guide starts with national figures, then explains what goes into interior and exterior painting quotes, what pushes the cost up or down, and when to book each kind of job, so you know what you're comparing when the quotes come in.
How much does it cost to paint a house?
HomeStars' 2026 Canadian cost guide gives these typical ranges:
- Full interior, 1,500 to 2,000 sq ft: $2,000 to $5,000
- Full interior, 2,500 to 3,500 sq ft: $4,000 to $8,000
- Exterior repaint, 1,500 to 2,000 sq ft: $3,000 to $8,000
- Interior and exterior, 1,500 to 2,000 sq ft: $6,000 to $15,000 or more
These are HomeStars' national estimates. They don't necessarily reflect Bay City Painters' prices, and your home could come in higher or lower. For a price based on your home, contact us for a free quote.
What goes into an interior painting quote
An interior painting quote is built from the surfaces being painted and the work it takes to get them ready. A typical quote covers:
- Walls, the biggest part of most jobs.
- Ceilings, usually quoted on top of the walls.
- Trim, baseboards, window casings and doors, which are slower, detailed work.
- Repairs and prep: filling holes, sanding, caulking and priming.

What goes into an exterior painting quote
An exterior painting quote depends on how much surface there is, what it's made of, and how hard it is to reach. A typical quote covers:
- Exterior walls, whether they're wood, vinyl, stucco or brick.
- Trim, soffits, fascia and doors.
- Prep: washing, scraping loose paint, repairing wood, caulking and priming.
- Access: ladders, plus scaffolding or lifts for tall walls.
Two- and three-storey homes, dormers and steep rooflines take more ladder and scaffold work, which adds time.
What drives the cost of painting a house
HomeStars puts labour at 60 to 70% of a typical painting quote, so anything that adds time adds cost. The biggest factors:
- Prep work. This is the biggest variable. Peeling paint, wood rot or moisture problems can double the labour cost.
- Size and height. More wall area, high ceilings and extra storeys all add hours.
- Colour changes. Going from dark to light usually takes a tinted primer plus two coats.
- Paint quality. Premium paint costs more per litre, but it covers better and holds up longer.
- Access. Tight side yards, landscaping and steep rooflines slow the work down.
Why older Hamilton homes need more prep
Neighbourhoods like Durand, Kirkendall and Corktown are full of century homes, and they usually need extra prep. Plaster walls crack, old trim carries many layers of paint, and original wood needs careful scraping and priming.
Health Canada says a home built before 1960 probably contains lead-based paint, and that the exterior of a home built between 1960 and 1990 may too. It's a serious hazard when it's chipping, flaking or within reach of children, and sanding it or using a heat gun creates toxic dust and fumes. Ask any painter how they handle prep on an older home.
Interior or exterior: when to book each
Book interior work in winter, and line up exterior work early for spring.
- November to April: interiors. With exterior season over, winter is usually the easiest time to get on a painter's schedule for indoor work.
- Winter and early spring: get exterior quotes. Many standard exterior paints need about 10°C or warmer, overnight lows matter too, and some products are rated for colder conditions, so check the can. In Ontario that makes the practical season roughly May to October. Demand peaks from June to August, when painters book up weeks ahead.
- Peeling paint or bare wood outside? Do that first. Interior paint is mostly about looks. Exterior paint protects your siding and trim from water, so a failing exterior shouldn't wait.
Temperature, humidity and freeze-thaw all play a part, and we cover them in the best time to paint your exterior.
How to compare quotes and stretch your budget
Every home is different, so a painter needs to see yours to give you a real number. When you collect quotes:
- Get three to five written quotes. Be wary of outliers at either end. A quote far below the rest usually means prep is being skipped.
- Compare what's included. Each quote should spell out the prep work, the number of coats, the paint brand and product, and whether ceilings, trim and doors are covered.
A few ways to save without cutting corners:
- Paint the whole interior at once rather than room by room, so setup and cleanup only happen once.
- Do the easy prep yourself: move furniture, take down pictures and remove outlet covers.
- Use premium paint in kitchens, bathrooms and hallways, and mid-range paint in low-traffic rooms.
