Attic insulation in Sainte-Julienne
In Sainte-Julienne, 91.1% of homes are single-detached houses, which means almost as many attics as households. Isolation Cornerstone visits them at no charge, then sends a written quote.
Rue Cartier and the streets named for his children
Joseph-Édouard Beaupré, originally from L’Assomption, went up the Saint-Esprit River and founded a settlement that lived off the waterfalls, with eight mills. The heart of the village is a residential development he planned at the foot of the church, with Rue Cartier, and the neighbouring streets carry the names of his children.
Nearly one home in two predates 1981: 15.1% from before 1961 and 32.9% from 1961 to 1980. When the insulation in one of those attics is thin, packed down or uneven, heat passes right through.
- 15.1% Before 1961
- 32.9% 1961 to 1980
- 19.5% 1981 to 2000
- 32.6% Since 2001
Single-detached houses: 91.1% · semi-detached or row houses: 1%

Nine houses in ten
LogisVert targets houses, and that is almost all the municipality has, with only 5.5% apartments. If the house is heated mainly with electricity, the roof insulation and the caulking are done in the same project. The order in the attic stays the same: air leaks sealed, a baffle at every soffit, ducts vented outside, the hatch weatherstripped, insulation blown in last, with safety clearances kept around the chimney, the light fixtures and the ducts.

Hi! Pick a question and we’ll answer right here.
Choose a question
- Which comes first in my Sainte-Julienne house, the caulking or the roof insulation?
- Ceiling air leaks first, then the blown-in insulation last. Isolation Cornerstone does the roof insulation and the caulking in the same project, which is what LogisVert asks for, and Hydro-Québec decides who qualifies.
- 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.
- Is the visit for the quote really free?
- Yes. Isolation Cornerstone comes to look at the attic at your address and gives you a written quote, at no charge and with no pressure.
