What a insulation costs in Calgary

Why insulation matters in Calgary

In Calgary, the average January low is -12°C, colder than 91% of the 123 cities we track. With winters this cold, the attic is usually the best place to start. Ask the installer to seal air leaks around lights, pipes and the attic hatch before adding insulation, or much of the benefit is lost.

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 Calgary. Many programs require approval or a registered contractor before work starts.
