Blower door testing which depressurizes a home can reveal the location of many leaks. A blower door test locates air leaks by using a special fan to depressurize a house. Blower door tests are conducted before and after air sealing to measure the effectiveness of the work.
This testing will provide a thorough and accurate measurement of air leakage in your home. QCS technicians will then determine areas in your home that need better sealing or caulking.
