Window replacement in Canada should prioritize energy efficiency — look for ENERGY STAR® certified windows rated for your climate zone. Double-pane is minimum; triple-pane is recommended for zones 2 and 3 (most of Canada). Argon or krypton gas fill between panes adds 10–15% to cost but significantly improves insulation. Replace all windows at once if possible — contractors offer better per-window pricing for full-house jobs.
Window frame material is the largest cost factor: vinyl ($400–800/window), fiberglass ($600–1,200), aluminum-clad wood ($800–1,500), and full wood ($1,000–2,000+). Unusual sizes, bay/bow windows, and casement styles cost 30–100% more than standard double-hung. Installation complexity (brick vs. wood siding, second-floor access) affects labour costs.
💡 Pro Tip
Check for federal and provincial rebates before purchasing — the Canada Greener Homes Grant and provincial programs can cover $125–250 per window for ENERGY STAR® upgrades, potentially saving $2,000–$5,000 on a full-house replacement.

Saint John's coastal climate brings heavy fog, salt air, and maritime moisture. Exterior materials must be corrosion-resistant — vinyl and fiber cement siding perform better than wood in this environment. The Bay of Fundy's extreme tides can affect coastal property drainage.
