Local expert
Your thermos specialist in Saint-Jérôme
Fog between the panes means the seal on your sealed unit has failed. In Saint-Jérôme, the sealed units of both old homes and recent constructions 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-Jérôme: thermos units built for Laurentian winters
As the regional capital of the Laurentians, Saint-Jérôme pairs an older downtown, around the cathedral and the Rivière du Nord, with large residential areas that came with the merger of Bellefeuille, Lafontaine and Saint-Antoine. Downtown has older townhouses and apartment buildings, while the outer sectors have bungalows, two-storey homes and newer builds, often on bigger lots than in the suburbs closer to Montreal.
Further north than Montreal Island, Saint-Jérôme generally gets colder, snowier winters. The gap between a heated interior and freezing outdoor air is hard on sealed units: fog, then frost between the panes, then lost insulation. In these conditions, triple glazing with argon and Low-E is often a smart choice, especially on north-facing walls where the January sun offers little help.
Bellefeuille and Lafontaine have plenty of homes on large lots, sometimes set well back from the road, so keep a clear path to the door, especially in winter. Saint-Jérôme is an easy drive up Highway 15, and travel is still free. Tip: use the assessment to check every window in the house; grouping replacements saves you from going through it all again next year.

FAQ
Questions about Saint-Jérôme

Do you replace the sealed unit of houses?
