Blower Door Testing
What is a Blower Door?
A blower door is a powerful fan that a trained energy professional mounts into the frame of an exterior doorway of a building. The fan is used to pull air out of the house, also known as negative pressure, or is used to push air into the house, also known as positive pressure. Once the fan is activated, the air pressure flows through all unsealed gaps, cracks, and openings, such as wire or plumbing penetrations.
Why Perform a Blower Door Test?
Simply put, a leaky house is an inefficient house with poor indoor air quality. This means higher energy costs, a greater toll put on the grid or larger amounts of fossil fuels consumed, and poor health outcomes for the occupants. Performing a blower door test allows a trained energy professional to diagnose leaky areas of the building. Think of a this like an emissions test. Newly adapted building codes and tax incentive programs are now requiring blower door testing.

Does LBS Perform Diagnositc Blower Door Testing?
Yes we do! A diagnostic test is included with our Air Sealing Service. Although these tests are critical for understanding how airtight a building is, the test itself does not seal up the gaps and cracks. Traditionally, a tradesperson follows up a blower door test by manually air sealing with caulk or spray foam, which includes a lot of guesswork and is very time consuming.
It’s Time for the Construction Industry to Ditch Manual Air Sealing!
Our Air Sealing Division guarantees that you hit your targeted airtightness goals. An AeroBarrier installation is an automated, effective, and efficient process that removes all the guesswork. For new construction projects, renovations, or vacant buildings, we recommend bringing in our Air Sealing Division from the get-go, as a baseline diagnostic blower door test is always the first step. Step two, we make the building airtight in less than a day!
