Local expert
Your thermos specialist in Boucherville
Fog between the panes means the seal on your sealed unit has failed. In Boucherville, the sealed units of houses and bungalows 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
Boucherville: heritage homes and riverside neighbourhoods
Boucherville is one of Quebec's oldest towns, and Vieux-Boucherville still has heritage homes built of stone and wood. Around that historic core, the city spread out into neighbourhoods of detached houses, semis and split-levels, then into newer developments. Windows range from traditional divided-light styles to modern casements, but they all have one thing in common: sealed units that eventually break down and cloud over.
In renovated older homes, thermos units often have grilles set between the panes to keep the original look. When the seal fails, condensation collects around those bars and dulls them. If your unit has built-in grilles, mention it when you ask for a quote and we'll go over the options for the new unit. Near the river, where the wind often blows hard, triple glazing with argon and Low-E makes exposed rooms much more comfortable.
Streets in Vieux-Boucherville are narrower and parking can be limited, so tell us where we can leave the vehicle near your door. For a heritage property, check with the City about any rules before making visible changes; replacing only the thermos, without touching the frame, is often the most discreet option. Elsewhere in town, access through a private driveway is usually straightforward.
