Local expert
Your thermos specialist in Sainte-Thérèse
Fog between the panes means the seal on your thermos has failed. In Sainte-Thérèse, from Old Sainte-Thérèse to the newer residential neighbourhoods, many double-glazed windows are reaching the end of their life.
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
From Old Sainte-Thérèse to suburban streets: your windows
Sainte-Thérèse has two sides. Around Rue Turgeon and Collège Lionel-Groulx, the old core mixes older houses, plexes and small apartment buildings, where windows were often replaced a few at a time over the years. Farther from downtown, suburban streets are lined with bungalows and cottages with sliding or casement windows, most of them installed all at once. Each part of town calls for a slightly different approach.
In homes where windows were changed at different times, you often end up with thermos units of different ages: some are holding up, others are fogging. Instead of redoing everything, we target only the failed units and match the right thickness. If your unit faces a busy road, thicker glass or an asymmetric glass build-up can also help cut noise.
In Old Sainte-Thérèse, street parking can be tight near the shops and the train station, so let us know where the truck can park. For an upstairs unit, give your landlord or neighbours a heads-up if we'll be using a shared staircase. In the suburban areas, access is more straightforward; just clear the space in front of the windows. Saturday mornings work well for many households.

FAQ
Questions about Sainte-Thérèse
Do you serve Sainte-Thérèse?
Yes, we work throughout Sainte-Thérèse, from Old Sainte-Thérèse to the residential areas. The assessment and travel are free.
What are the turnaround times in Sainte-Thérèse?
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.
Only two of my windows are foggy. Do I need to replace the rest?
No. During the free assessment we check every thermos and only replace the ones with a failed seal. That's common in Sainte-Thérèse, where many homes have windows installed at different times.
I live near Boulevard du Curé-Labelle. Can a new thermos reduce noise?
A unit built with two different glass thicknesses dampens some traffic noise better than a standard thermos. We'll tell you what your frame can accommodate and give you a clear quote before ordering the unit.
