How much should I budget for painting all the window sills in a large Ottawa home?

Window sill painting costs in Ottawa typically range from $15 to $40 per linear foot depending on the condition, material, and level of prep work required. For a large Ottawa home with 25 to 35 windows, you're looking at roughly $1,200 to $3,500 for professional window sill painting.

The wide cost range reflects the reality that window sills take more punishment than any other painted surface in Ottawa's climate. South and west-facing sills endure intense UV exposure during summer, while all sills face brutal freeze-thaw cycles that crack paint and allow moisture infiltration. Many Ottawa homes built before 1980 have wood sills that may need extensive repair or replacement of rotted sections before painting can begin. If your sills require wood filler, caulking replacement, or partial board replacement, expect costs toward the higher end of the range.

Material type significantly impacts pricing. Wood sills require the most prep work and benefit from oil-based or hybrid alkyd primers for superior adhesion and moisture resistance. Vinyl and aluminum sills need specialized bonding primers but generally require less repair work. Stone or concrete sills may need masonry primer and elastomeric paint to handle thermal movement.

The biggest cost driver is prep work intensity. Simple cleaning and light sanding might add only $5 to $10 per linear foot, while extensive scraping, wood repair, and priming can double the total cost. Many contractors price window sills as part of full exterior painting projects, which often provides better value than standalone sill work.

Critical warning: If your home was built before 1978, window sills are high-probability locations for lead paint due to friction from window operation. Professional lead testing and possible abatement add significant cost but are legally required for contractor work and essential for safety.
