Local expert
Your thermos specialist in Sainte-Anne-de-Bellevue
Fog between the panes means the seal on your sealed unit has failed. In Sainte-Anne-de-Bellevue, the humidity of Lac des Deux-Montagnes increases condensation on the windows of both old and recent homes.
Good news: replacing the whole window is rarely necessary. We replace only the faulty sealed unit within the existing frame, preserving the character.
Custom glass for non-standard dimensions, free diagnosis, transparent pricing from $150.

Local context
Sainte-Anne-de-Bellevue: thermos units facing two lakes
At the western tip of the island, Sainte-Anne-de-Bellevue centres on Sainte-Anne Street and its boardwalk along the canal, lined with older houses and shops with apartments upstairs. Beyond it, residential streets hold single-family homes and small apartment buildings, while McGill's Macdonald Campus and John Abbott College take up a large part of the territory. Windows range from small older panes to large bays looking out over the water.
The town sits where Lake of Two Mountains meets Lac Saint-Louis, so waterfront homes take steady wind and constant humidity — conditions that wear down a thermos seal. Large panes facing the water are the most exposed. We often recommend triple glazing, or double glazing with argon and Low-E, plus tempered glass for patio doors and oversized panes. Each option is explained during the free assessment, room by room.
Near Sainte-Anne Street, parking is limited, especially in summer when the boardwalk is busy, so plan a spot or rear access. If you rent, we can email the quote directly to your landlord. At the junction of Highways 20 and 40, the town is easy to reach. Assessment and travel are free, weekdays 8 a.m. to 6 p.m. or Saturdays 9 a.m. to 4 p.m.
