Fog between the panes means the seal on your sealed unit has failed. In Saint-Laurent, the sealed units of houses and older plexes are often reaching the end of their life.
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
Saint-Laurent: from postwar bungalows to Bois-Franc condos
Saint-Laurent mixes very different eras. Around Old Saint-Laurent and the CEGEP you'll find plexes and older houses; Norgate and Chameran are mostly postwar bungalows and duplexes; Bois-Franc and Nouveau Saint-Laurent add newer townhouses and condos. Each area has its own window sizes, from narrow sliders to wide terrace patio doors, so we never assume a standard size and measure every opening on site.
The borough borders Montréal-Trudeau airport and has large industrial zones, and those wide-open spaces let wind sweep freely around buildings. In newer condos, big glazed areas sometimes fog up after only a few years when a seal fails. Depending on the case, we install double or triple glazing with argon and Low-E, plus tempered glass for patio doors and large windows.
In a condo, window rules vary: check with your syndicate or property manager whether the unit is common property, and book the elevator if needed. In Norgate or Chameran, a private driveway makes parking simple. Côte-Vertu metro and Highways 13 and 40 make the area easy to reach, and both the assessment and travel are free. Weekday and Saturday appointments are available.

FAQ
Questions about Saint-Laurent

Do you replace the sealed unit of houses?

I own a condo in Bois-Franc — who has to approve the replacement?
It depends on your declaration of co-ownership. In many buildings, windows are common areas for restricted use, so the syndicate has to sign off. We can email the quote to your property manager to help move the decision along.
My Norgate bungalow has unusual window sizes — is that a problem?
Not at all. Every unit is custom-made to the exact measurements taken during the free assessment, in 24 to 72 hours. Whether the window is narrow or extra wide, we replace only the thermos in the existing frame.
