What the camera finds in Saint-Jean-sur-Richelieu houses
Of Saint-Jean-sur-Richelieu's 26,960 houses (single-detached, semi-detached, row houses and duplexes), 19% were built before 1961 and 60% before 1991, according to the 2021 Census. Older houses are where the camera earns its keep: empty or settled wall cavities, gaps at the top of walls, and cold corners where framing bridges the insulation. Run it with the blower door test depressurizing the house and every leak shows up as a cold streak.

When is the best time for a thermal imaging inspection in Saint-Jean-sur-Richelieu?

Can a thermal camera see through walls?
No. It reads surface temperatures. Missing insulation or an air leak shows up because it changes the temperature of the wall or ceiling surface.
