What changes the price of sealing in London
- Colour change and detail work - going dark-to-light, using multiple colours, or painting lots of railings, spindles, and trim adds coats and slow cutting-in time.
- Home size and number of storeys - more surface area means more paint and labour, and tall or steep spots need ladders, scaffolding, or lifts that add hours and equipment cost.
- Surface condition and prep - peeling, cracked, or weathered wood and chalking siding need scraping, sanding, power washing, and priming; heavy prep can add $1-$2 per sq ft and is usually the biggest swing in a quote.
- Surface material - smooth vinyl, aluminum, or wood siding is cheaper to coat than rough stucco, brick, or fussy wood trim, which soak up more paint and take longer.
- Paint or stain quality and number of coats - premium exterior paint and solid stains cost more per can but last longer, and two coats cost more than one.
- Labour is 60-75% of the bill - access difficulty (multi-storey walls, steep rooflines, tight landscaping) drives the labour hours that dominate the total price.
How sealing prices vary across Canada
Big cities run meaningfully higher, almost entirely on labour. Metro Vancouver and BC are typically the most expensive - deck staining runs $3-$8 per sq ft there versus $2-$5 nationally, and exterior jobs sit at the top of every range. Toronto and the GTA carry a similar urban labour premium. Alberta tends to be the most competitive of the big-city markets, and smaller towns and rural areas trend about 10-15% below the national range.
These are typical London-area price ranges based on 2026 Canadian market data, not quotes. Your actual cost depends on the size and details of your project. Post your project on Bidmii to get free quotes from the 7 sealing contractors listed in London above.

How much does it cost to paint the exterior of a house in Canada?
Most homeowners spend $3,000-$8,000 for a full two-storey repaint, or roughly $3.50-$6.50 per square foot of paintable surface. Smaller bungalows often run $1,800-$4,500, while large or premium homes can top $12,000.
Is it better to stain or paint a deck or fence?
Staining is usually cheaper upfront, soaks into the wood, and is easy to refresh without heavy scraping - about $2-$5 per sq ft on a deck. Paint can cost a bit more and hides flaws well, but when it fails it peels and needs more prep next time. Most people stain wood decks and fences and paint siding.
How often do I need to repaint or re-stain?
Good exterior paint typically lasts 5-10 years depending on sun and weather exposure. Deck and fence stain wears faster because those surfaces take direct sun and foot traffic, so plan to re-stain every 2-4 years to keep the wood protected.
