Why insulation matters in Mississauga

In Mississauga, the average January low is -8°C, colder than 74% of the 123 cities we track. Sealing air leaks and topping up the attic usually pays back fastest here. Basement walls and rim joists are often the next biggest heat loss in older homes.

Most rebate programs pay only after an energy assessment, and some need one before the work too. Book it first.

Before you hire a insulation installer

  1. Ask whether they will air-seal before insulating, and what they will seal (attic hatch, pot lights, pipes, top plates).
  2. Ask for the R-value before and after for each area, and the material and depth they will install.
  3. Ask whether your rebate needs an energy assessment before and after the work, and who books it.
  4. Ask how they handle ventilation and any old insulation that could contain vermiculite (asbestos risk).

Before you call anyone, check what insulation rebates you can get in Mississauga. Many programs require approval or a registered contractor before work starts.
