What Affects Window Replacement Pricing?
Several key factors influence the final cost of your project:
1. Window Size & Shape
Larger windows or custom shapes (arches, bays, oversized units) increase material and labor costs.
2. Frame Material

Vinyl is more affordable and low maintenance.

Fiberglass costs more but offers superior durability and stability in Ottawa’s freeze-thaw climate.

Upgrades such as:
-
Triple-pane glass
-
Low-E coatings

Argon or krypton gas fills
-
Warm edge spacers
increase upfront pricing but can reduce heating costs long-term.

Are Energy Efficient Windows Worth It in Ottawa?
In most cases — yes.

Heat loss

Condensation buildup

While triple-pane windows cost more initially, many homeowners find that lower heating bills and improved comfort justify the upgrade.
