What hidden costs should I watch out for with window replacement?

Most window replacement projects have additional costs beyond the basic window price that homeowners don't initially consider. The biggest surprise is often the extent of trim work and finishing required after installation.

Structural and preparation costs can add significantly to your budget. If your existing window frames are rotted or damaged, you'll need carpentry repairs before new windows can be installed. Older Ottawa homes often have settling issues or non-standard openings that require custom sizing or structural adjustments. Asbestos or lead paint remediation in pre-1980s homes can add $200-500 per window in specialized removal costs.

Interior and exterior finishing work is frequently underestimated. New windows rarely fit the exact dimensions of old ones, leaving gaps in drywall, siding, or brick that need professional repair. Interior trim replacement or refinishing can cost $100-300 per window, while exterior caulking, painting, and siding repairs add another $150-400 per window. Many contractors quote "installation only" and treat finishing as separate line items.

Permit and disposal fees vary by project scope. While most replacement windows don't require permits in Ottawa, structural changes or new openings do, adding $200-800 in permit costs. Old window disposal isn't always included and can cost $50-100 per window. Some installers also charge extra for difficult access situations, like second-story windows or tight spaces.

Energy efficiency upgrades often seem optional until you realize the long-term costs of skipping them. In Ottawa's Climate Zone 6, choosing double-pane over triple-pane windows might save $200 per window upfront but cost hundreds annually in heating bills. Quality Low-E coatings and proper air sealing are essential for maximizing your Canada Greener Homes Grant eligibility.
