Your glazier in Côte-Saint-Luc for thermos glass replacement: we replace only the sealed unit in your existing frame — custom glass, free diagnosis, transparent pricing.
Local expert
Your thermos specialist in Côte-Saint-Luc
Fog between the panes means the seal on your sealed unit has failed. In Côte-Saint-Luc, internal condensation affects both duplexes and apartment buildings.
Good news: replacing the whole window is rarely necessary. We replace only the faulty sealed unit within the existing frame, with custom glass.
Custom glass for non-standard dimensions, free diagnosis, transparent pricing from $150.

Local context
Côte Saint-Luc: sealed units for towers, condos and homes
Côte Saint-Luc packs a lot of apartment living into a small city. Rental buildings and condo towers line Cavendish Boulevard and Kildare Road, while quieter streets are home to post-war single-family houses and duplexes. Nearly every apartment has a sliding patio door onto a balcony, plus casement or slider windows. In the houses, you'll usually find a large picture window in the living room and smaller units in the bedrooms, each with its own dimensions.
Higher up, sealed units take more wind and a bigger temperature swing between the heated interior and the outdoors. Over time the seal lets moisture in, which shows up as foggy windows or a whitish film between the panes. For balcony patio doors, we build the replacement thermos in tempered glass, the standard for that kind of door. On west-facing windows that bake in the late-day sun, Low-E glass with argon keeps rooms cooler in summer and warmer in winter.
If you live in a tower, book the service elevator and let your property manager or condo board know before we come. Visitor parking near the larger buildings can be tight, so tell us where to park. Houses are usually straightforward. One tip: list every foggy thermos by room, floor and side of the building, and snap a photo if you can. It makes the quote more accurate and the visit shorter.

FAQ
Questions about Côte-Saint-Luc
Do you serve Côte-Saint-Luc?
Yes, we work throughout Côte-Saint-Luc, from Westminster Avenue to the residential areas. Diagnosis and travel are free.
What are the timelines in Côte-Saint-Luc?
Diagnosis is done quickly on site, then your sealed unit is custom-made within 24 to 72 hours.
Do you replace the sealed unit of apartment buildings?
Yes, we replace the sealed unit of building windows, coordinating with the association when needed.
Do I need my condo board's approval to replace a thermos in Côte Saint-Luc?
Windows are often treated as common property reserved for your use, so check your declaration of co-ownership and notify the board. Because we keep the existing frame, the building's exterior looks exactly the same, which usually makes approval simple.
My balcony patio door is foggy. Does the whole door need replacing?
Not if the frame and rollers are still in good shape. We make a new tempered-glass sealed unit to the exact size of the panel and install it in your existing frame. The in-home assessment costs you nothing.
