If you’ve been getting quotes that all look different, you’re not imagining it. So, how much does it cost to paint a house Ontario wide in 2026 – 27? Most homeowners pay somewhere between $3,000 and $25,000, depending on whether the job is interior, exterior, or both, and how much prep the surfaces need. At MPK Painting GTA, we quote projects across the region every week, and this guide breaks down exactly what drives that number so you can budget with confidence before you request a quote.
Painting is still one of the highest-return home upgrades available, but pricing only makes sense once you understand what’s behind the per-square-foot number. Below, we cover interior costs, exterior painting cost GTA homeowners can expect, commercial painting GTA rates, deck staining Brampton pricing, cabinet painting Oakville costs, and the best paint colours 2026 has to offer.
Note: Every figure in this guide is a 2026-27 planning range based on typical GTA projects. Your exact price depends on your home’s size, surface condition, and scope, so treat these numbers as a starting point rather than a fixed quote.
How Much Does It Cost to Paint a House in Ontario? Quick Answer
For most Ontario homes, a full interior repaint runs $2 to $5 per square foot of wall area, while exterior work runs $2.50 to $6 per square foot. A whole-home project covering both typically lands between $7,000 and $25,000. Smaller jobs, like a single room or a bungalow exterior, sit well below that range. Labour makes up 60 to 80 percent of any painting quote in Ontario, which is why prep work and surface condition affect price more than the paint itself.
Interior Painting Costs in Ontario
Interior painting across the GTA generally costs $2 to $5 per square foot of wall surface, depending on paint quality, ceiling height, and how many coats the walls need. A single bedroom typically runs $300 to $800, while a full-home interior for a mid-size detached house lands between $4,000 and $9,000.
A few things push interior pricing up:
- Ceilings and trim. Adding ceilings typically adds $1 to $2 per square foot on top of wall rates, and trim or baseboards add $1 to $3 per linear foot.
- Older homes. Plaster walls and surfaces that have been repainted many times need more prep, which means more labour hours.
- Paint quality. Premium lines cost more per gallon, but they usually mean fewer coats and a longer-lasting finish.
- Dark or saturated colours. These often require extra coats to achieve full, even coverage.
Exterior Painting Cost GTA Homeowners Should Expect
Exterior painting cost GTA wide runs $2.50 to $6 per square foot of paintable surface in 2026. That translates to real project totals of:
- Bungalow or small home: $3,500 to $7,500
- Standard two-storey home: $6,000 to $12,000
- Large or detail-heavy home: $10,000 to $20,000+
Exterior pricing isn’t based on your home’s floor area; it’s based on the actual paintable surface, which includes peaks, dormers, porches, railings, and trim. Two houses with identical floor plans can have very different exterior quotes depending on roofline complexity and access. Siding material matters too: vinyl siding is generally the most affordable to prep, while wood and aluminum siding take longer to clean and prime before the first coat goes on.
Commercial Painting GTA Pricing
Commercial painting GTA businesses budget for typically falls between $1.50 and $5 per square foot, depending on the space type and how much of the work needs to happen outside regular business hours. A few working examples:
- A 3,000 sq. ft. office with standard ceilings usually lands between $7,500 and $13,500.
- A small 1,200 sq. ft. retail unit painted overnight often runs $2,400 to $4,800.
- Warehouses and industrial spaces with high ceilings can add 15 to 40 percent to the baseline rate because of lift and scaffolding requirements.
Evening, overnight, and weekend work commonly adds 15 to 30 percent to a commercial quote, since crews work shorter shifts and buildings often require added security coordination. Scheduling a commercial repaint for late fall or winter, when demand is lower, can also help keep costs down.
Deck Staining Brampton Costs
Deck staining Brampton homeowners typically pay $2 to $4 per square foot for professional work, which lines up with pricing across most of the GTA. For a standard 300 to 400 sq. ft. deck, that works out to roughly $600 to $1,600 in total.
A few factors that move the price:
- Surface condition. A weathered deck with peeling old stain needs sanding and pressure washing first, which can add $1 to $2 per square foot.
- Stain type. Oil-based and solid stains cost more per gallon than semi-transparent options but generally last longer.
- Railings and stairs. These are priced separately (often per linear foot) because they take more labour time relative to their surface area.
Most professionals recommend restaining a deck every two to three years to protect it against Ontario’s freeze-thaw winters.
Cabinet Painting Oakville Pricing
Cabinet painting Oakville homeowners request most often falls into three general tiers based on kitchen size and door count:
- Small kitchen (15–20 doors/drawers): $2,000 to $3,800
- Medium kitchen (20–30 doors/drawers): $3,800 to $5,500
- Large or custom kitchen: $5,500 to $8,500+
Cabinet refinishing is priced by door and drawer count, not square footage, because prep work drives most of the labour. A typical job spends roughly five out of six working days on degreasing, sanding, masking, and priming, with only a fraction of the timeline spent on the actual topcoat. That’s also why DIY cabinet jobs fail more often than people expect: skipping the prep stages is the single biggest reason a fresh coat peels within the first year.
Best Paint Colours 2026: What’s Trending in the GTA
If you’re repainting anyway, 2026 is a good year to update your palette. The best paint colours 2026 has brought to the forefront lean warm and grounded rather than the cool grays that dominated the last decade:
- Warm greige tones: a blend of gray, beige, and taupe that reads softer than a flat gray
- Muted sage and smoky greens: inspired by Behr’s 2026 Color of the Year, a smoky jade-green shade
- Warm neutrals like khaki and wheat: including Sherwin-Williams’ 2026 Color of the Year, a warm khaki tone
- Terracotta and clay accents: used on front doors, shutters, and feature walls rather than full exteriors
- Colour-drenched rooms: walls and ceilings painted the same tone for a cocooned, intentional look
For exteriors specifically, warm greiges and soft sage greens are proving popular choices for GTA homeowners looking to refresh curb appeal without following a trend that will feel dated in five years.
What Affects Your Final Painting Quote
Regardless of the project type, four variables move your price the most:
- Size and layout of the space being painted
- Condition of existing surfaces, since repairs and heavy prep add labour hours
- Paint quality, as premium products often reduce the number of coats needed
- Access and scheduling, including height, occupied spaces, and after-hours work
A detailed, itemized quote should always break out labour, materials, prep, and the number of coats included, so you can compare estimates on equal footing.
