Attic insulation in Saint-Constant
In Saint-Constant, 40.6% of homes date from 1981 to 2000, the period when a house’s first insulation may have aged. Isolation Cornerstone comes up to the attic for free, then sends a written quote with no pressure.
A city since 1973, built mostly after 1980
Saint-Constant gained city status in 1973, after two decades of housing growth. The Saint-Régis and Saint-Pierre rivers cross its territory, but most roofs are newer than those first streets: 40.6% from 1981 to 2000, 34.6% since 2001, and only 5.3% from before 1961.
In a 1990 house, the original insulation may have aged. The bathroom, range hood and dryer ducts are directed outdoors before the insulation is blown in, and the hatch gets weatherstripping.

Hi! Pick a question and we’ll answer right here.
Choose a question
- Which comes first in a 1990 house, the insulation or the caulking?
- Both are done in the same project, since LogisVert targets roof insulation and caulking together. In the attic, the ceiling air leaks are sealed before the insulation is blown in.
- Blown-in fibreglass or batts: which is better in the attic?
- Blown-in fibreglass, at Isolation Cornerstone. It reaches the corners nobody can crawl into and forms an even layer from wall to wall, at R-51 minimum, with depth rulers left standing in it so you can read the depth yourself.
- 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.
