Seal leaky ductwork from the inside with Aeroseal duct sealing for Marin and Sonoma County homes with weak airflow, dusty rooms, and high energy bills.
Leaky ductwork can waste conditioned air before it ever reaches the rooms where your family needs it. Aeroseal duct sealing helps close hidden gaps inside the duct system without tearing open walls or ceilings.
John Owens Services evaluates airflow, duct leakage, filtration concerns, and comfort complaints so Marin and Sonoma homeowners get a practical plan instead of a guess. If Aeroseal is the right fit, our team seals the ducts and verifies the improvement.
Our licensed local team understands older North Bay duct systems, remodel history, crawlspaces, attics, and comfort complaints that show up room by room.
Aeroseal seals many small leaks from inside the duct system, helping more heated or cooled air reach the rooms instead of escaping into attics, crawlspaces, or wall cavities.
No. Large disconnected ducts, damaged runs, or crushed sections may need repair first. We inspect the system and recommend the practical path.
It can help reduce the amount of dusty, smoky, or unconditioned air pulled from dirty spaces into the duct system, especially when paired with filtration and airflow corrections.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
