Duct Sealing (Mastic, Accessible Runs) in The Woodlands, 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 The Woodlands (7 ZIP codes, 114k residents) and surrounding neighborhoods with same-week scheduling.

Local dossier · The Woodlands, TX
The Woodlands was designed around its forest, and the forest is why air quality here behaves differently from the rest of Montgomery County. Loblolly pine pollen in late winter is heavy and highly visible, but it is also relatively large, and a competent filter catches most of it, provided air is actually going through the filter and not slipping around a loose frame or in through return leaks. That is the first thing worth checking, because it determines whether your filter is doing anything at all. The canopy has a second effect: shade keeps attics cooler than in the open subdivisions nearby, but it also keeps them damper for longer, and cool damp attic air condensing on supply boots is what produces the staining people notice at register edges. Most homes here were built between the 1990s and the 2010s and run gas furnaces, so the cabinet and flue come into the inspection alongside 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.
