Duct sealing in Shasta-Hanchett

Bungalows and small ranches with retrofitted air and tight access.

Attic access is tight and ceilings should stay closed. Internal sealing is how we reach those joints in a day.

The visit is the same across San Jose: leakage test, internal seal if the ducts are intact, and a written before-and-after. You do not need to empty the attic or open ceilings.
