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.
Mississauga's renovation costs track closely with Toronto but are typically 5–10% lower due to slightly reduced labour demand. The city's mix of condos, townhomes, and detached houses from the 1970s–2000s means many properties are entering their first major renovation cycle. Proximity to Toronto gives homeowners access to the GTA's large contractor pool.
Mississauga requires permits for structural, plumbing, and electrical work. The city offers express permits for simple projects like water heater replacements. Standard permit processing takes 10–15 business days.
Mississauga shares Toronto's humid continental climate with cold winters and warm summers. Lake Ontario proximity moderates temperature extremes slightly but adds humidity, making ventilation important in any renovation.
