Your thermos specialist in Boisbriand
Fog between the panes means the seal on your thermos has failed. In Boisbriand, the housing stock — from established bungalows to the newer homes of the Faubourg Boisbriand — includes many ageing thermos units.
The good news: there's no need to replace the whole window. We replace only the failed sealed unit in your existing frame, with custom-made glass.
Custom glass for non-standard sizes, free assessment, transparent pricing starting at $150.

Local context
Boisbriand: from the Faubourg to the Mille Îles shore
Boisbriand has two sides. On one, established neighbourhoods of bungalows and split-levels, with sliding and picture windows that have often been upgraded over the years. On the other, the Faubourg Boisbriand, built on the former GM plant site, with townhouses, condos and glass-heavy façades. The first sealed units installed in these newer buildings are already reaching the age when seals start to weaken and fog appears.
Near the Rivière des Mille Îles, along Chemin de la Grande-Côte, being close to the water keeps the air more humid. When a thermos seal has aged, that moisture builds up between the panes and stays there. Rather than attempting to defog it, we build a brand-new unit. For the large windows in Faubourg condos, Low-E glass with argon is a sensible choice to keep glass-heavy rooms from overheating.
In condo buildings, check the house rules before booking a date: elevator reservations, parking access and permitted work hours. For houses along Chemin de la Grande-Côte, a private driveway is usually all we need. If you have both a foggy window and a foggy patio door, mention both when you call so everything gets measured during a single visit to your home.

FAQ
Questions about Boisbriand
Do you serve Boisbriand?
Yes, we work throughout Boisbriand, from the Faubourg Boisbriand to the residential areas. The assessment and travel are free.
What are the turnaround times in Boisbriand?
The assessment is done quickly on site, then your thermos is custom-made within 24 to 72 hours.
Do you replace thermos units in houses?
Yes, we cut custom glass to the exact dimensions of your windows and install it in the existing frame.
My Faubourg Boisbriand condo is less than 20 years old. Can a thermos fail already?
Yes. How long a sealed unit lasts depends on sealant quality, sun exposure and indoor humidity. Fog between the panes means the seal has failed, whatever the building's age. The assessment and travel are free.
Do you defog windows near the Rivière des Mille Îles?
No. We don't offer injection defogging, since the seal itself stays broken. We replace the complete sealed unit, custom-made in 24 to 72 hours, and install it in your existing frame.
