Many air leaks and drafts are easy to find because they are easy to feel — like those around windows and doors. But holes hidden in attics, basements, and crawlspaces are usually bigger problems. Sealing these leaks with caulk, spray foam, or weather stripping will have a great impact on improving your comfort and reducing utility bills.

Homeowners are often concerned about sealing their house too tightly; however, this is unlikely in most older homes. A certain amount of fresh air is needed for good indoor air quality and there are specifications that set the minimum amount of fresh air needed for a house.

CRI Technicians are skilled in evaluating current and needed air flow, systematically reducing excessive infiltration and carefully adhering to important indoor air quality standards.

Blower door testing and blower door guided air sealing is a scientific test that involves the use of a large fan (Blower Door) mounted in an exterior door to measure air filtration into your home. The CRI Technician will be able to seal most of the major sources of leakage while on-site.

The result of this test will be reviewed with you by the CRI Technician. Properly sealing the leaks in your home’s structure is a technically demanding and often time consuming process, one that is best done using state-of-the-art, blower door technology.
