What to know about Basement insulation
Basement insulation covers the concrete foundation walls, the rim joist at the top of the foundation and sometimes the floor slab. In many older Canadian houses these surfaces are bare, and the upper part of the foundation wall, which faces cold soil and winter air, is where much of the basement's heat escapes. Insulating it makes the lower level warmer, more comfortable and usable year-round, and it eases the load on the heating system.

How to choose insulation contractors in Le Plateau-Mont-Royal
- Choose a contractor who talks about air sealing and ventilation, not only adding more insulation.
- Ask them to check the attic or walls for moisture, mould, old wiring or insulation that may contain asbestos before starting.
- Get a written quote that states the type of insulation, the areas covered and the target insulation level.
- For spray foam, ask about their training, curing time and when it's safe to be back in the home.
- Consider an energy audit before and after the work to see where heat is being lost.

- What will you do if you find old insulation that may contain asbestos, mould or old wiring?
