How your duct sealing service works
Assessment & inspection
We inspect your ductwork, attic, basement and airflow balance. No detail is overlooked before we begin.
Initial pressure test
We pressurize the system to measure the exact amount of air escaping. This provides a clear baseline.
Aerosol sealing
A non-toxic, water-based sealant is released as fine particles. They collect around the edges of each leak and seal it from the inside.
Certification & report
A computerized report compares duct leakage before and after the service, often showing a reduction of up to 95%. You receive measurable proof of the work completed.
