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.
Laval offers renovation costs 5–10% lower than neighbouring Montreal, with easier contractor scheduling and less competition for skilled trades. The city's predominantly post-1960s housing stock — many bungalows, split-levels, and early condos — is now entering its first or second major renovation cycle. Laval homeowners benefit from Quebec's large network of RBQ-licensed contractors and competitive material pricing from big-box stores clustered along the autoroutes.
Laval issues permits through its Service de l'urbanisme. Residential permits typically take 5–15 business days depending on complexity. As in all of Quebec, contractors must hold an RBQ licence for work exceeding $5,000. Laval's urban planning regulations are generally more flexible than Montreal's, especially for suburban properties.
Laval shares Montreal's cold continental climate with harsh winters (-10°C average in January) and warm, humid summers. The city's flat terrain and proximity to the Rivière des Prairies means some areas are prone to spring flooding — basement renovations should include sump pump installation and proper waterproofing.
In 2026, a windows renovation in Laval costs between $4,025 (budget) and $21,160 (premium). The average standard cost ranges from $5,750 to $13,225.
