What is Air Sealing, and why is it essential to improve my home's comfort and performance?

Air Sealing is the most critical retrofit activity and should be considered first in your home retrofit/upgrade strategy.

Air Sealing is essential every time you insulate or make changes to the building envelope to ensure moisture does not enter the insulation or building envelope.

Air Sealing involves identifying and sealing as many air leakage paths as possible with weather-stripping and caulking or applying gaskets and tape.

How can I find out the airtightness of my home?

A blower door test can be a powerful tool in helping understand how air-tight your home is; this is included in your pre-retrofit EnerGuide Assessment.

Are there other things to consider while improving the airtightness of your home?

As leakages are controlled, household humidity levels rise (impacting indoor air quality). Consider installing heat recovery ventilators (HRVs) or energy recovery ventilators (ERVs) to improve your home's indoor air quality.

Unfortunately, HRVs and ERVs are not reimbursable under the Canada Greener Homes Grant. However, some of the provincial or municipal programs may cover these under their grants (e.g. the Home Energy Retrofit Accelerator in Edmonton)

What are some of the major areas where air leakage occurs?

Some of the critical problem areas for air leakage in your home include:

  1. Attic hatch
  2. Ceiling penetrations into the attic
  3. Door
  4. Exhaust vent(s)
  5. Mail slot
  6. Sill and header
  7. Service entry
  8. Floor drain(s)
  9. Foundation crack
  10. Electrical outlet(s)
