Blower Door Tests in Utah — Cost, Value, and Rebate Requirements
When measured leakage tests are worth it, how numbers translate to comfort, and why some rebates require before/after documentation.
A blower door quantifies envelope leakage in CFM at a reference pressure. It is the fastest way to stop arguing about “draftiness” and start prioritizing fixes. Some rebate pathways require pre- and post-tests; others use visual inspection tiers.
Expect to invest in a test when you want proof air sealing worked or when a program demands it. Pair results with thermal imaging so leaks become a to-do list, not a vibe. The dollar cost is usually minor compared to the cost of insulating without sealing first.
