What Affects Your Price

Several factors move your cost up or down:

Window size — A small bathroom window costs less than a large living room picture window

Glass package — Low-E coatings, argon fill, and triple-pane all add cost but improve efficiency

Frame material — Vinyl is most affordable, fibreglass costs more, wood is premium

Installation type — Insert (retrofit) installation costs less than full-frame replacement

Accessibility — Second-floor or hard-to-reach windows may cost more to install

Custom sizes — Non-standard dimensions require custom manufacturing

Quantity — Replacing all windows at once typically gets you a better per-window price

Hidden Costs to Watch For

These often surprise homeowners:

Rotted frames or sills — If discovered during installation, repairs add $100-500 per window

Interior trim replacement — Often needed on older homes, $50-150 per window

Permit fees — Usually not required for like-for-like replacement, but changing window sizes needs a permit ($100-300)

Exterior capping — Aluminum cladding to cover old wood trim, $30-75 per window

Screen replacement — If existing screens don't fit, new ones cost $30-75 each

Budget 10-15% contingency for unexpected issues, especially in older homes.

How to Get the Best Value

Smart strategies for managing your window budget:

Get multiple quotes — Prices vary 20-30% between contractors for the same product

Compare apples to apples — Ensure quotes specify the same glass package and installation method

Consider timing — Late fall and winter may offer better pricing due to lower demand

Bundle the job — Replacing all windows at once costs less per window than doing them in stages

Don't overbuy — Triple-pane is excellent, but double-pane with Low-E may be sufficient for your needs

Check rebates — Greener Homes Grant and Enbridge rebates can offset $2,000-5,000 of your costs
