Fog between the panes means the seal on your sealed unit has failed. In Saint-Lambert, the large windows of upscale homes and refined duplexes, often old, fog up over time.
Good news: replacing the whole window is rarely necessary. We replace only the faulty sealed unit within the existing frame, with custom glass that preserves the character.
Custom glass for non-standard dimensions, free diagnosis, transparent pricing from $150.
Local context
Saint-Lambert: big windows, mature trees and the Seaway
Just across the St. Lawrence from downtown Montreal, Saint-Lambert is known for its tree-lined streets and character homes, many of them from the first half of the 20th century. Around Victoria Avenue you'll also find duplexes and small apartment buildings, while the Préville sector is more purely residential. Windows tend to be generous here, sometimes divided-light or set in a bay.
A large sealed unit goes through more expansion and contraction: on a bay window or a wide living-room pane, the seal eventually gives out and fog blurs the view of the garden. Mature trees also keep some walls shaded, and damp, for longer. We build each unit to measure, in tempered glass for large panes, with argon and Low-E for year-round comfort.
On residential streets, parking in front of the house is usually possible; near Victoria Avenue, a spot on a side street works fine. For divided-light or decorative windows, point out the details during the assessment so we can confirm the best way to keep the original look. Right by the Victoria Bridge, Saint-Lambert is quick to reach from Montreal, and travel is free.

Why it happens here
Saint-Lambert: why your windows fog up
Bays & big panes
Large units flex more with frost, putting extra stress on their seal.
Mature trees
Shaded walls dry slowly, and that moisture tests the seals.
Character homes
We keep the original frame and look; only the sealed unit is replaced.
Tempered glass
Large glazed areas get a unit made with tempered glass.

FAQ
Questions about Saint-Lambert
Do you serve Saint-Lambert?
Yes, we work throughout Saint-Lambert, from downtown to the residential areas. Diagnosis and travel are free.
What are the timelines in Saint-Lambert?
Diagnosis is done quickly on site, then your sealed unit is custom-made within 24 to 72 hours.
Do you replace the large windows of upscale homes?
Yes, we custom-cut glass to the exact dimensions of your windows and install it in the existing frame, preserving the character.
I have a big bay window — can you replace it without a new window?
Yes, as long as the unit sits in a frame that's in good shape. We measure the opening during the free assessment, then build a custom tempered-glass unit in 24 to 72 hours. The frame, trim and interior finish all stay put.
Do the trees out front affect which glass I should choose?
They can. A heavily shaded wall gets less winter sun, so the right Low-E coating helps keep heat inside. A wide-open south-facing room, on the other hand, can use a Low-E that limits overheating. We advise you wall by wall.
