The questions below address what Renfrew County homeowners most commonly ask when evaluating painting projects — from licensing (or its absence) to how climate affects exterior paint longevity, what to know about lead paint in older homes, and whether any tax credits apply.
Do painters need a licence in Ontario?
No — painting is not a regulated trade in Ontario. There is no provincial painting licence, and anyone can legally operate a painting business. The Ontario College of Trades does not include painting as a regulated or voluntary trade.
This makes verification of other credentials more important. Before hiring:
- Request WSIB Clearance Certificate (verifiable at wsib.ca)
- Request certificate of commercial general liability insurance
- Ask for references and examples of completed work
The absence of a licensing standard places more responsibility on the homeowner to vet qualifications.
When is the best time for exterior painting in Ontario?
The ideal exterior painting window is May through September, when temperatures are consistently above 10°C and humidity stays below approximately 85%. Most exterior latex paint products require temperatures above 10°C during application and for several hours afterward for proper film formation and curing.
Conditions to avoid:
- Painting in direct, hot afternoon sun — causes rapid drying and blistering
- Application before rain or when rain is forecast within 24 hours
- High humidity periods — paint will not cure properly and adhesion suffers
- Temperatures dropping near or below 10°C within 24 hours of application
In Renfrew County, July and August offer the most reliable conditions, with May–June and September providing adequate windows in most years.
How long does exterior paint last in Renfrew County's climate?
With quality product and proper prep, 6–10 years — generally toward the lower end compared to milder Ontario regions. Renfrew County's climate presents three main challenges to exterior paint durability:
- Freeze-thaw cycles — water that penetrates any surface imperfection expands as ice, accelerating peeling
- Extended cold winters — paint becomes brittle and is more susceptible to cracking and impact damage
- UV exposure — south-facing surfaces experience significant UV degradation over time
The single most effective way to maximize exterior paint longevity in this climate is thorough surface prep and premium paint products. A budget paint job on Renfrew County housing stock may show early failure at the 3–4 year mark.
What should I know about lead paint in older homes?
Homes built before 1978 are likely to contain lead-based paint. Lead was a common ingredient in residential paint products in Canada until it was substantially restricted. Renfrew County has significant housing stock from before 1978, particularly in Pembroke, Renfrew town, Arnprior, and throughout rural townships.
Key facts:
- Intact lead paint that is in good condition is generally not an immediate hazard
- Disturbing lead paint through sanding, scraping, or abrasive cleaning creates hazardous lead dust
- Health Canada classifies deteriorated or disturbed lead paint as a health hazard
- Children and pregnant women are at highest risk from lead exposure
Professional testing — using XRF (X-ray fluorescence) equipment or laboratory analysis of paint chip samples — is recommended before any mechanical surface work on pre-1978 homes. Do not allow surface sanding or scraping before testing on an older home.
How many coats of paint are needed?
The standard for most painting projects is one coat of primer plus two coats of finish paint. This applies to:
- New surfaces or bare wood
- New drywall
- Significant colour changes (especially going lighter over dark or vice versa)
- Surfaces where existing paint has been stripped or is in poor condition
For same-colour refreshes on surfaces in good condition with intact, sound existing paint, two total coats may be adequate. Skipping primer on bare wood, new drywall, or water-stained surfaces is a common cause of early paint failure — a spot primer at minimum is typically needed on problem areas even in refreshes.
Can I paint my home's exterior myself?
Yes, in many cases. Exterior painting quality depends more on prep and product than on who applies it. If you are comfortable working at heights, have time for proper surface preparation, and invest in quality exterior paint, DIY exterior painting is achievable on most single-storey homes.
Consider hiring a professional when:
- The home is two storeys or more, requiring scaffolding or extended ladder use
- The home has complex ornate trim, multiple substrate types, or heritage features
- The home was built before 1978 and has not been tested for lead paint — lead-safe work practices require specific training and equipment
Can I claim painting on my taxes?
Generally no — routine residential painting is not eligible for personal tax credits as a standalone expense. Two potential exceptions:
- Home Accessibility Tax Credit (HATC): If painting is part of an accessibility renovation for a senior or person with a disability (for example, repainting a bathroom after grab bar and ramp installation), a portion may qualify. Consult a tax professional.
- HST Rebate for Substantial Renovations: If painting is part of a qualifying substantial renovation (as defined by CRA — generally renovating more than 90% of a residential unit's interior), HST paid may be partially recoverable.
For rental property owners, painting is generally deductible as a maintenance expense. See the HST Rebate for Renovations page for more detail.
