Attic insulation in Blainville
In Blainville, 36% of homes date from 1981 to 2000, in a city that Highway 15 and Route 117 have gradually turned into a bedroom community since the 1980s. Isolation Cornerstone redoes the insulation in those attics, and the visit is free.
Houses from 1981 to 2000 and their original insulation
Blainville was built on the St. Lawrence lowlands, north of the Mille Îles River, in what was once a strongly agricultural area. Building carried on after 2001: 45.2% of homes date from that period, and only 3.2% from before 1961.
In the first wave of houses, the original insulation may have packed down, and heat then passes right through.
The job always follows the same order: ceiling air leaks sealed, a baffle at every soffite, the hatch insulated with weatherstripping, then the insulation, blown in last. See also our page on attic ventilation.

Almost two homes in three are single-detached houses
Blainville has 64.2% single-detached houses and 77.7% of households owning their home. That sits close to the audience Hydro-Québec’s LogisVert measure is aimed at: houses heated mainly with electricity, with a roof at R-50 over its whole surface and caulking done together.

Hi! Pick a question and we’ll answer right here.
Choose a question
- My house in Fontainebleau was built around 1995: is its insulation still holding up?
- After thirty years, insulation can settle. The visit is free, at your address, and a written quote follows with no pressure. After the work, depth rulers stay set in the insulation, so you read the thickness yourself.
- 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.
- How long does the work take?
- The exact time is given with the quote, once the attic has been seen. On the day of the work, the house is protected with tarps and cleaned before the crew leaves.
