Fog between the panes means the seal on your sealed unit has failed. In Saint-Léonard, the sealed units of bungalows, duplexes and apartment buildings built in the second half of the 20th century 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-Léonard: brick duplexes and half-basement windows

Much of Saint-Léonard was built in the 1960s and 1970s, which gives it a fairly consistent look: brick duplexes and triplexes, bungalows and small apartment buildings, often with a half-basement flat. Sliding and casement windows dominate, with patio doors opening onto backyards and balconies out front, especially around Jean-Talon Street and along Lacordaire and Langelier boulevards, where similar buildings line block after block.

Half-basement windows sit almost at ground level, where they get snow, runoff and moisture from the soil, so their thermos units can fog up before the ones upstairs. Units put in during earlier renovations are also reaching the end of their life. We replace them with double glazing, argon and Low-E, and build back patio door units in tempered glass.

In winter, clear the snow in front of half-basement windows before we arrive so outdoor access is safer. In a duplex, the upper flat is often reached by an outdoor staircase, and we plan the handling accordingly. Street parking is usually easy in residential areas. Whether you live in the building or rent it out, a single quote can cover several units at once.

My half-basement window is foggy — do you replace those too?
