Blower Door Tests: Find the Leakage… Fix the Leakage!

Did you know that every residential project in Washington State now requires a blower door test to be performed on it if the permit was pulled after January 1, 2011? Insulation Northwest has the training, staff and equipment to provide these tests, find any problem areas, and provide assistance to correct any over limit air leakage from your project!

We can even provide a same-day follow up test at little or no charge in many cases!
