Attic insulation in Sainte-Thérèse
In Sainte-Thérèse, nearly six homes in ten are apartments, and 28.4% are single-detached houses. Isolation Cornerstone insulates the attics of the city’s houses, in the old core and beyond, and the visit is free.
A city of apartments, and a few attics of your own
LogisVert excludes apartment buildings and multiplexes: the Hydro-Québec program is aimed at houses heated mainly with electricity. If you have a house, detached, semi-detached or row, the attic above your ceiling is what this page is about.

The old core, a village in 1849 and a city in 1916
The Village of Sainte-Thérèse came into being on June 1, 1849 and became a city in 1916. That past shows in the census: 15.6% of homes date from before 1961, and 33.9% from 1961 to 1980.
A house from before 1961 may have thin batts, layers added over the decades and, sometimes, vermiculite. If you think you have some, don’t touch it and don’t climb up to check: describe what you saw, and it comes out first.

Hi! Pick a question and we’ll answer right here.
Choose a question
- My duplex is excluded from LogisVert: can I still ask for a visit?
- Yes. LogisVert excludes multiplexes, but the free visit and the written quote are still offered by Isolation Cornerstone. Hydro-Québec decides on LogisVert.
- Is it better to blow new insulation over the old rather than strip it all out?
- Depends on what is underneath. A blocked soffit or warm air leaking through the ceiling would stay hidden under the new layer, so Isolation Cornerstone fixes those first, then blows. Vermiculite is never covered over: it comes out first.
- I think there is vermiculite in my attic. What should I do?
- Leave it alone, and don’t go up to check. Vermiculite can contain asbestos, according to Health Canada. Describe to Isolation Cornerstone what you saw, even from a distance: the crew comes to look at it, and it comes out before any insulation goes in.
