How much does it cost to paint window frames and casings on an Ottawa home?

Window frames and casings are one of those detail jobs that really make a home look sharp when done right — and pretty rough when they're neglected. Here in Ottawa, where our freeze-thaw cycles punish every exposed surface, keeping your window trim properly painted isn't just cosmetic, it's protective.

Typical Ottawa Pricing for Window Trim Painting

Most Ottawa painters charge $35 to $75 per window for painting the frame and casing, depending on size, condition, and accessibility. For a standard three-bedroom home with 15 to 20 windows, you're looking at roughly $525 to $1,500 for the full job. That's about 10-15% less than what you'd pay in the GTA for comparable work.

Here's how the costs generally break down:

• Standard single-hung or double-hung windows: $35-$55 per window
• Large picture windows or bay windows: $65-$120 per window
• Casement windows with multiple panes: $50-$75 per window
• Second-storey windows requiring ladder work: add $15-$25 per window
• Heritage windows with muntins and detailed profiles: $75-$150 per window

What Affects the Price

Prep work is the big variable. If your casings have peeling paint, moisture damage, or old caulking that needs to be stripped and redone, expect prep costs to add 30-50% to the base price. Ottawa's brutal winters — where temps plunge to -30C and back — cause wood trim to expand and contract constantly, which means more cracking and peeling than you'd see in milder climates.

Paint type matters too. For exterior window frames, your painter should be using a high-quality acrylic latex rated for Canadian winters. Products like Benjamin Moore Aura Exterior or Sherwin-Williams Duration hold up well against our 200+ cm of annual snowfall and the ice buildup that forms along window sills. Budget roughly $50-$70 per gallon for premium exterior trim paint.

For interior casings, a semi-gloss or satin finish is standard — it's durable, easy to clean, and highlights the trim work nicely. Interior trim paint runs $40-$60 per gallon, and a gallon typically covers 15-20 windows.

Interior vs. Exterior Considerations

If you're doing interior casings only, the job is more straightforward — no weather concerns, no ladder surcharges. A full interior window trim repaint on a typical Ottawa home runs $400 to $1,000.

Exterior frames require more attention. Your painter needs to check for wood rot, failed caulking, and any gaps where moisture could infiltrate. In Ottawa, water getting behind trim paint in October becomes ice by November, and that ice will lift paint right off the wood. Proper prep includes scraping, sanding, priming bare wood, and re-caulking all joints with a paintable silicone or polyurethane caulk.

Heritage District Considerations

If your home is in a heritage conservation district — places like the Glebe, Sandy Hill, New Edinburgh, or Rockcliffe Park — you may face restrictions on colour choices and materials. The City of Ottawa's heritage guidelines generally require colours that are historically appropriate for the architectural style. Your painter should be familiar with these requirements, and some heritage jobs require a permit application before work begins.

When to Schedule the Work

Exterior window painting in Ottawa has a tight season — ideally mid-May through September when temperatures stay consistently above 10C. Paint applied in cool or damp conditions won't cure properly and will peel within a season. Interior work can be done year-round.

Getting It Done Right

A proper window trim paint job should last 5-8 years on exteriors and 8-12 years on interiors in Ottawa conditions. The key is thorough prep and quality materials — cutting corners on either means you'll be repainting sooner than you'd like.
