Duct Sealing (Mastic, Accessible Runs) in Austin, 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 Austin (60 ZIP codes, 975k residents) and surrounding neighborhoods with same-week scheduling.

Local dossier · Austin, TX
Austin is the rare Texas city where most housing units are not detached houses, and that single fact changes the conversation. In a condo tower, a stacked fourplex or an East Austin ADU, the system is usually a closet air handler with short runs and one hallway return grille. There is not much duct to clean, and the real leverage is filter fit and whether the return is pulling air from a plenum or corridor instead of your rooms. Detached houses split their own way here: an older core around Hyde Park and Travis Heights with retrofit routing, and a post-2010 ring built tight enough that indoor air is close to whatever the equipment makes it. Then there is cedar. Ashe juniper pollen arrives in December fine enough to pass an ordinary filter and stay airborne indoors for weeks. Cleaning removes what has settled. It does nothing about what is coming, and we would rather say so.

Duct Sealing (Mastic, Accessible Runs) in Austin (Travis County) — what's local
Austin sits in Travis County (county seat: Austin). For duct sealing (mastic, accessible runs) that means our Austin crew sizes up the local housing stock before quoting — and follows Travis County permit requirements for any work that needs an inspection sign-off.
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.
