Duct Sealing (Mastic, Accessible Runs) in New Braunfels, 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 New Braunfels (5 ZIP codes, 98k residents) and surrounding neighborhoods with same-week scheduling.

Local dossier · New Braunfels, TX
New Braunfels has grown quickly, with a large share of its homes going up since 2010, but it also keeps a meaningful stock of manufactured housing and a river-corridor geography that changes the work. Manufactured homes have no attic duct at all; the runs sit in a belly board beneath the floor inside a moisture barrier, and the first thing to establish is whether that wrap is torn and whether anything has moved in. That is a repair question before it is ever a cleaning question. Along the Comal and the Guadalupe, lots hold humidity longer, and cool supply surfaces sitting in damp crawl and slab-edge air will condense and stain. Heating here is nearly all electric, so there is no flue or heat exchanger in the picture. Attention goes to the coil where moisture collects, and to the strip heaters that scorch settled dust every first cold morning.

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.
