Duct Sealing (Mastic, Accessible Runs) in Katy, TX
Where the ductwork is reachable — attic trunks, crawlspace runs, the takeoffs and boots at the air handler — the honest fix is a brush and a bucket of mastic. We locate and photograph the leaks first, then hand-seal each connection: takeoff collars, boot-to-drywall joints, plenum seams, and every place foil tape has dried out and curled away. Mastic with fabric mesh embedded over the wider gaps, UL 181-listed tape only where the manufacturer specifies it. This costs a fraction of aerosol sealing and does the same job on connections a technician can reach. It cannot touch a leak buried in a sealed chase — if that is where your losses are, we will say so and quote the aerosol method instead. Price follows joint count and how much of the system is genuinely accessible. Serving Katy (7 ZIP codes, 22k residents) and surrounding neighborhoods with same-week scheduling.

Local dossier · Katy, TX
Katy is a young housing market with an old water story, and both shape what your ductwork needs. A large share of homes inside the city were finished after 2010, which means the systems have not been running long enough to collect much of anything from use. What they carry instead is construction debris left in the boots before the registers went on, and that is a single cleanup rather than a recurring service. The water part matters differently. Homes in the reservoir and bayou watersheds have taken on floodwater in the past, and duct liner, insulation and air handlers that were submerged cannot be restored by cleaning. They get replaced. Katy also leans heavily on gas furnaces, most of them mounted in the attic, where nine idle humid months leave dust on a cold cabinet and produce a strong burning smell on the first cold morning. That smell usually starts at the furnace, not in the duct.

Scoped from a camera inspection
At Prime Air Duct Experts, a duct sealing (mastic, accessible runs) is never guesswork. We scope every job from a camera look inside the ducts first — weighed against EPA guidance on when the work is actually warranted — so what you approve is matched to what your system actually needs, with the photos to prove it. And if the camera says the work isn't needed, we tell you that instead.
