What is a Home Airtightness Assessment?

A Home Airtightness Assessment is a diagnostic tool used to measure how much air is entering or escaping from your home.

Our Registered Energy Advisor will perform a blower door test, which involves a frame, fan, and air pressure gauge fitted to your doorway. The fan creates a controlled depressurization, drawing air through gaps and cracks in your home’s structure. The advisor will also walk through your home with you to help identify and strategize about areas of leakage. After the assessment, you'll receive a detailed report with findings and recommendations for enhancing your home's airtightness.

How Can a Home Airtightness Assessment Help?

A home airtightness assessment offers numerous advantages. It helps identify and minimize air leaks, leading to lower heating and cooling costs. Homes lose heat through conduction (directly through building materials) and convection (air movement). Sealing air leaks is as crucial as adding insulation. Air leaks can also contribute to moisture problems, so effective air sealing helps reduce moisture movement and protect building materials.

Improving airtightness can enhance indoor air quality by preventing the infiltration of pollutants and allergens, creating a healthier living environment. It also improves comfort by ensuring consistent temperatures and reducing drafts.

An airtightness assessment can uncover areas where animals or pests might enter the home and prevent unpleasant odors from seeping in through shared walls.

Overall, enhancing your home's airtightness promotes greater comfort, efficiency, and well-being.
