How Much Does It Cost to Repaint an Ottawa Home Exterior That Is Peeling Badly?

A badly peeling exterior is one of the most common reasons Ottawa homeowners call a painter — and unfortunately, it's also one of the most expensive exterior paint jobs because of the extensive preparation required. The good news is that once it's done properly, you won't be dealing with this again for 8-12 years. Let me give you honest Ottawa pricing.

Ottawa Pricing for Peeling Exterior Repaints

For a badly peeling exterior on a typical Ottawa home:

• Small bungalow (1,000-1,200 sq ft footprint): $6,000-$10,000
• Standard two-storey (1,200-1,800 sq ft footprint): $8,000-$15,000
• Large two-storey or split-level: $12,000-$20,000
• Heritage home with detailed trim (the Glebe, Rockcliffe, New Edinburgh): $15,000-$30,000+

Compare these to a non-peeling exterior refresh (light prep, 2 coats): $4,000-$8,000 for the same size home. The difference — often 50-100% more — is entirely driven by preparation labour.

Ottawa prices are roughly 10-15% below Toronto for comparable work, though extreme prep cases narrow that gap because labour hours are similar.

Why Peeling Exterior Paint Costs So Much More

Preparation on a peeling exterior consumes 50-70% of the total project cost. You can't just paint over peeling paint — the new coating will peel right off the failing layer underneath. Every square inch of loose, flaking, or bubbling paint must be removed down to a sound surface.

Here's the typical preparation process and what each step costs:

• Pressure washing (2,500-3,000 PSI): $300-$600 — removes loose paint, dirt, mildew, and chalking
• Scraping (hand scraping with carbide scrapers): $1,500-$4,000+ — this is the big labour item; a badly peeling home can take 2-4 painters 2-3 days just to scrape
• Sanding (feathering scraped edges smooth): $500-$1,500 — where scraped and unsound paint meets sound paint, edges must be feathered so they don't show through the new finish
• Caulking (windows, doors, trim joints): $300-$800 — Ottawa's temperature extremes open caulk joints regularly
• Wood repair/replacement (rotted trim, fascia, window sills): $500-$3,000+ — peeling paint almost always means some wood has been exposed to moisture and rotted
• Priming (bonding primer on all scraped areas): $500-$1,500 — bare wood and previously painted surfaces need different primers

Ottawa's Climate: Why Exteriors Peel in the First Place

Ottawa is arguably one of the hardest cities in Canada on exterior paint. The combination of:

• Extreme temperature range: -30°C to +35°C means paint films expand and contract dramatically
• UV exposure: Ottawa gets surprisingly strong summer sun that degrades paint binders
• Freeze-thaw cycles: 100+ freeze-thaw cycles per year (more than most Canadian cities) — moisture gets behind paint film, freezes, expands, and pushes paint off the substrate
• 200+ cm of snow annually: Snow piled against siding, ice dams on eaves, and spring melt all drive moisture into exterior surfaces
• High summer humidity: Prevents proper drying between rain events

These factors mean Ottawa exteriors need higher-quality paint and more thorough preparation than homes in milder climates to achieve reasonable longevity.

Paint Quality Is Non-Negotiable

On a peeling repaint, using cheap paint is throwing money away. You've already invested heavily in preparation — protect that investment with premium exterior paint:

• Benjamin Moore Aura Exterior: $75-$90/gallon — the gold standard, exceptional adhesion, fade resistance, and flexibility
• Sherwin-Williams Duration Exterior: $70-$85/gallon — excellent self-priming properties, great for repaint work
• Benjamin Moore Regal Select Exterior: $60-$75/gallon — solid mid-premium option
• PPG Timeless Exterior: $55-$70/gallon — good value performer

A typical Ottawa two-storey exterior requires 12-20 gallons for two coats. Spending an extra $200-$400 on premium paint adds years of life to the job.

Lead Paint Considerations

For Ottawa homes built before 1978, there's a significant chance the peeling paint contains lead. Many homes in Centretown, the Glebe, Sandy Hill, Old Ottawa South, and Lowertown are well within this era. Ontario's Occupational Health and Safety Act and federal regulations under Health Canada guidelines require specific handling of lead paint:

• Lead paint test: $30-$50 for DIY kit, $200-$400 for professional testing
• Lead-safe work practices: adds $1,000-$3,000+ to the project (containment, HEPA filtration, proper disposal)
• Full lead abatement (if required by condition): $5,000-$15,000+

This isn't optional — a painter who scrapes lead paint without containment is violating Ontario regulations and creating a health hazard for your family and neighbours.

Timing Your Project

Ottawa's exterior painting season is May through September, with the sweet spot being June through early September. For a peeling repaint specifically:

• Book early — peeling repaints take 5-10 days (vs. 2-4 for standard repaints), so painters have limited slots
• Avoid spring — Ottawa homes are often still damp from snowmelt through May
• Best months: June and September — moderate temperatures, lower humidity

Finding the Right Contractor

A peeling exterior repaint is not a job for the cheapest bidder. You need painters who:

Carry full WSIB coverage (required for working at height in Ontario)

Have experience with badly deteriorated surfaces — ask for before-and-after photos

Will provide a written warranty — reputable Ottawa painters warranty exterior work for 3-5 years

Use proper fall protection for second-storey work

Browse Ottawa Paint Contractors through the Ottawa Construction Network directory to find experienced exterior painters who handle full prep-and-repaint projects. Get at least three quotes, and be wary of any quote that seems dramatically lower — they're almost certainly planning to cut corners on preparation, which means you'll be doing this again in 2-3 years.
