Montreal window replacement — warmer rooms, lower bills
Full-frame and retrofit replacement for drafty, failed or dated windows across Montreal. ENERGY STAR® triple-pane glass with two Low-E coatings and argon fill drops the U-factor, keeps the inside glass warm, and stops the condensation that soaks sills on cold winter mornings. Most homeowners feel the difference the first cold snap and see it on the heating bill by spring.
If a window is drafty, fogged or painted shut, the honest first question is whether a sealed-unit repair buys a few more years or a full replacement is the smarter spend. We give you both numbers at the estimate and say which way we would go on our own house — one fogged pane is often just a glass swap, but a wall of 1980s aluminum sliders is throwing good money after bad.
A full-home energy-efficient replacement with triple-pane, Low-E and argon glass pays you back every winter in a warmer house and a lower heating bill, and lifts resale value at the same time. We size the glass package to each wall, so the west side that takes the wind gets the performance it needs without over-spending elsewhere.
Choose full-frame replacement when the frames, sills or surrounding wood show rot or water damage — we take the opening back to the studs and re-flash it properly. Choose retrofit replacement when the existing frames are sound, for a faster, tidier, less costly install. Either way you get one written price with tear-out, haul-away and a frame-and-glass warranty.

Montreal window replacement — cost, rebates, glass, timing
Cost, glass, timing and full-frame vs retrofit for Montreal.
Expect roughly $650–$1,200 per standard-size vinyl replacement window supplied and installed in Montreal, with casement, bay/bow and triple-pane units at the higher end and simple double-hungs at the lower. A whole-home project of 8–12 windows usually runs $8,000–$18,000 installed. The exact figure depends on your window styles, the glass package and whether any openings need full-frame work behind the old units — all of which we confirm in a written, itemized quote after a free in-home measure. Tear-out, haul-away and the written warranty are already included, and financing is available on approved credit.
Retrofit fits a new window into your existing, sound frame — it is faster, tidier and less costly because we are not disturbing the interior or exterior trim. Full-frame removes everything down to the rough opening, which is the right call when the frames, sills or surrounding wood show rot, water damage or air leaks that a new insert cannot fix. Full-frame also lets us re-insulate and re-flash the opening properly, so it is the more thorough long-term fix. At the measure we check the condition behind your current windows and tell you which one each opening actually needs — often a mix of both across one house.
For most Montreal homes, yes. Triple-pane glass with two Low-E coatings and argon fill noticeably cuts the cold-glass draft, lowers heat loss and reduces the condensation that forms on the coldest mornings. The difference is biggest on north- and west-facing walls that catch the winter wind and in rooms where you sit close to the glass. It is not automatically right for every opening, though — at the estimate we show you the U-factor gain and the price gap side by side so you can decide room by room instead of paying one spec across the whole house.
Most 8–12 window homes are a one- to two-day project once your windows arrive. Larger homes, full-frame replacements that need re-capping, and bay or bow units add time. Weather and the condition of the existing openings move the number a little, too. We give you a realistic day count in the written quote up front, confirm the schedule before your windows are ordered, and on multi-day jobs we seal every opening we start so the house is never left open overnight or through a cold snap.
Yes — tear-out and haul-away of the old windows is included in the quote, and we leave the site cleaner than we found it.

What Montreal homeowners say after replacement

★★★★★
Swapped twelve tired old windows for triple-pane. The heating system runs far less and the west rooms finally hold their heat.
B. Thiessen
Homeowner, Montreal
★★★★★
They explained full-frame versus insert honestly instead of pushing the pricier option. Replacement went in over two tidy days.
C. Janzen
Homeowner, Laval
★★★★★
No more frost on the glass in the morning. The new sealed units made a bigger comfort difference than we expected.
D. Warkentin
Homeowner, Longueuil
★★★★★
Old aluminum frames were sweating and rotting the sills. The crew fixed the rot and sealed it right — bills already down.
