Frequently Asked Questions
Where should I start insulating?▾
With the attic and air sealing, almost always. That is where cost versus gain is best, and it is also what reduces ice dams.
My attic has old granular insulation. What now?▾
Have it tested before any work. Some vermiculite installed before the 1990s contains asbestos, and disturbing it without precautions is dangerous.
Can more insulation cause condensation?▾
Yes, if ventilation is blocked or air sealing is neglected. Moisture rising into a poorly vented attic condenses and damages the structure.
Is financial help available?▾
Energy efficiency support programs exist and change regularly. Check current conditions with the official bodies before ordering work.
How do I verify a contractor is licensed?▾
Ask for the RBQ licence number and search the Régie du bâtiment du Québec public registry.
Insulation in Québec: what to know
In a region with a long heating season, insulation is the first lever on the energy bill. It is also what solves ice dams at the roof edge.
The attic first
It is almost always the best return for the cost. Heat rises, and an under-insulated attic lets a large share of your heating escape. Adding insulation is not enough on its own: ventilation from soffit to ridge must be preserved and air leaks sealed, otherwise moisture gets trapped.
Vermiculite
If your attic holds a beige or golden granular insulation installed before the 1990s, have it tested before touching it: some vermiculite contains asbestos. A serious contractor refuses to work in an uncharacterised attic.
Crawl spaces
A cold, damp crawl space chills the floor above. Treating it combines insulation, moisture management and sometimes ventilation.
Licence
The contractor must hold a Régie du bâtiment du Québec licence, liability insurance and a CNESST clearance.
