Looking for an experienced glazier to restore the insulation of your windows or bring an architectural design project to life? Vitrerie Justalex combines local service, fast turnaround times and industry standards to serve the entire Montreal’s South Shore area.
Our reputation is built on two core residential and commercial services:
An eco-friendly alternative that involves replacing only the fogged or broken sealed glass unit, without replacing your existing frames.
Custom-designed glass showers, transparent railings, modern wine cellars, lacquered glass backsplashes and custom mirrors.
The climate on Montreal’s South Shore exposes our buildings to extreme temperature variations. Over the years, window seals can fail. Rather than investing large sums in removing your existing window frames (PVC, wood or aluminum), our team carries out a targeted energy-efficiency upgrade.
Our replacement insulated glass units are manufactured to the highest standards and feature a low-emissivity coating that blocks UV rays and keeps heat where it belongs.
This table summarizes the value of our work for residential and commercial projects in the region:

Custom glass creates an unparalleled sense of space while enhancing your home’s architecture. We bring the most ambitious projects of Sainte-Julie residents to life.
Custom enclosures, fixed walk-in-style panels, and pivot or sliding doors. We use 10 mm or 12 mm safety glass combined with premium-grade hardware (matte black, polished chrome, satin gold).
Perfect for modernizing an interior staircase or mezzanine, or securing an outdoor balcony without blocking the view of your surroundings.

Thanks to our service locations in Varennes and Saint-Bruno-de-Montarville, we provide rapid service across a wide area that includes Boucherville, Longueuil, Sainte-Julie, Verchères, Belœil, Mont-Saint-Hilaire, Saint-Lambert, and surrounding South Shore municipalities.
Not necessarily. Depending on your installation, adding a system consisting of a self-closing cylinder and a suitable latch may allow you to secure your access without completely replacing your patio door.
Absolutely. Our technicians travel throughout the South Shore to conduct a technical inspection, take precise measurements, and provide you with a clear, transparent quote—whether for replacing a sealed glass unit or installing a custom glass shower.
