Thermos replacement in Saint-Eustache

Old Saint-Eustache, around the church scarred by the 1837 battle and the Légaré mill, still has older stone and wood houses with windows in all sorts of proportions. Beyond it, the city spread out into neighbourhoods of bungalows and two-storey homes, then newer developments near Highway 640. That means anything from renovated older sashes to modern patio doors, each needing its own approach.

Several streets run along the Mille Îles River or the Rivière du Chêne, where there's more moisture in the air than further inland. Once a thermos seal weakens, that moisture gets in and condenses between the panes on cold days. We replace it with a brand-new unit — new spacer, new seal — in double or triple glazing, with argon and Low-E depending on which way the room faces.

In Old Saint-Eustache, streets are narrow and parking is tight, so let us know if access is through the yard. For a heritage home, we keep the frame and its trim: only the sealed unit changes, so the façade looks the same. If your building sits in a heritage area, check with the city before any visible change. Elsewhere, private driveways keep things simple. Assessment and travel are free, Monday to Saturday.
