Transform Your Home with Our Energy-Efficient Windows

In Quebec, window installation doesn't require a specific installation license - but the work must comply with the building code set by the Regie du batiment du Quebec (RBQ). That's why hiring an RBQ-licensed contractor matters: it protects you legally, satisfies your insurer, and ensures the work qualifies for programs like Reno-Climat. Our installers are fully licensed and compliant. Ask us for documentation during your free quote visit.

Ask whether they're RBQ-licensed and insured, how long they've been installing windows in Quebec, what brands they carry, how they handle air sealing and flashing, and what the warranty covers for both product and labour. Also ask about cleanup, timeline, and what happens if there's an issue after installation. A good installer answers all of this without hesitation. If they're vague on the warranty or can't give a firm timeline, that's a red flag. We address all of it upfront during your free quote visit.

Window warranties come in two parts: the manufacturer warranty (typically 10-25 years, covering glass seal failure, frame defects, and hardware) and the installation workmanship warranty we provide separately. Most quality windows carry a lifetime warranty on the frame and 10-20 years on the sealed glass unit. Our installation warranty covers air leakage, water infiltration, and anything related to how the window was fitted. We walk you through both before any work begins.

The biggest single improvement is replacing single-pane windows with double- or triple-pane units with a low-E coating and argon fill. If replacement isn't in the budget right now, window film, interior insulation kits, and heavy curtains can reduce heat loss temporarily - but for Montreal winters, those are stopgaps. Properly installed new windows with a low U-value (0.25 or lower) can cut heat loss by 30-50% and qualify you for Reno-Climat rebates. We can run the numbers for your home during your free quote.

Window installation costs in Montreal depend on window size, type (casement, double-hung, bay, etc.), glazing (double vs. triple pane, low-E coating), and frame material. For a standard double-hung or casement window, expect $400–$900 per window installed. Bay or bow windows run $1,500–$3,500+. Triple-pane windows cost more upfront but qualify for Reno-Climat rebates that offset a significant portion. Labour typically adds $150–$350 per window. We give you a fully itemized quote - no vague estimates - so you can see exactly what you're paying for before committing.

For Montreal homes, the key factors are: glazing (double vs. triple pane - triple is worth it for north-facing windows or rooms that are always cold), frame material (vinyl, fibreglass, or wood - each with different maintenance needs), U-value and energy rating (lower is better; aim for 0.25 or below), window operation type (casement seals tighter than double-hung - important in our climate), and whether your existing frame is in good condition or needs replacing. Also check if the window qualifies for Reno-Climat rebates - we'll confirm eligibility during your free quote.

Our window installation process: first, we measure and confirm the rough opening at your free quote visit - this prevents ordering the wrong size. Once the window arrives, we remove the old window and inspect the rough opening for rot, moisture damage, or structural issues. We install the new window with proper shimming and levelling, apply flashing tape around the exterior, seal with low-expansion foam on the interior, and finish with interior and exterior trim. Every install gets tested for smooth operation and air leakage before we leave. Typical single window takes 1–2 hours; a full house of windows is quoted as a multi-day project.
