Your thermos specialist in Côte-des-Neiges–NDG
Fog between the panes means the seal on your sealed unit has failed. In Côte-des-Neiges–NDG, internal condensation affects both NDG duplexes and apartment buildings.
Good news: replacing the whole window is rarely necessary. We replace only the faulty sealed unit within the existing frame, with custom glass cut to your exact dimensions.
Custom glass for non-standard dimensions, free diagnosis, transparent pricing from $150.

Local context
Côte-des-Neiges–NDG: plexes, rentals and Mount Royal slopes
The borough spreads across the western slope of Mount Royal, from the Université de Montréal and Saint Joseph's Oratory to the residential streets of Notre-Dame-de-Grâce. Housing is dense: brick duplexes and triplexes, three- and four-storey walk-ups, row houses and a few larger detached homes. A large share of homes are rentals, and windows have been replaced in waves, so thermos units of very different ages often sit side by side in the same building.
In a rental building, indoor humidity varies a lot from one apartment to the next: frequent showers, laundry dried indoors, limited ventilation. Bathroom and bedroom thermos units are often among the first to fog up. We replace only the affected units, window by window, inside their frames. Along the Décarie Expressway and the main arteries, triple glazing can also help cut down traffic noise.
In Côte-des-Neiges, steep streets and permit parking can make it hard to stop in front of the building, so reserve a spot if you can or point us to an accessible lane. Building owners are better off checking every apartment before the visit, so all the foggy windows go into a single quote. Remember to give your tenants enough advance notice for both measuring and installation.
