Frequently Asked Questions
What is the best insulation investment?▾
The attic, in the vast majority of homes from that era, combined with air sealing. Cost is moderate and the effect shows on the heating bill.
How do I insulate a basement without creating mould?▾
By treating moisture first, then choosing an assembly that lets the wall dry. An experienced contractor will explain why some older methods are avoided.
Do I need an air exchanger after insulating?▾
If the house becomes noticeably tighter, yes. Without air renewal, humidity and pollutants build up.
Is financial help available?▾
Energy efficiency programs exist and evolve. Check current conditions with official bodies before starting 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 Laval: what to know
Laval bungalows and cottages from the 1960s to 1985 were built to insulation standards far below today's. That is where the most interesting gains sit.
The attic
Most of these homes have an accessible attic where adding insulation is simple and cost-effective. The work must come with air sealing around hatches, recessed lights and ducts, otherwise moisture rises and condenses.
The basement
Finishing a basement without solving moisture and without suitable insulation causes mould problems. The chosen assembly must let the foundation wall dry, which rules out some traditional build-ups.
Ventilation
A better insulated, tighter house has to renew its air. The air exchanger belongs to the project, not to a later step.
Licence
The contractor must hold a Régie du bâtiment du Québec licence, liability insurance and a CNESST clearance.
