Duct Sealing (Aerosol) in New Braunfels, TX
Leaky ducts dump conditioned air into attics and wall cavities, and in most homes the worst leaks sit where nobody can reach them. Aerosol sealing works from the inside out: we mask the registers, pressurize the duct system, and release an atomized sealant that the escaping air carries to every gap, where it builds across the opening until it closes. The equipment measures duct leakage before and after, so you get a number on paper rather than a claim. We start with the test — if your system is already tight, we tell you and you pay for the test alone. Starting price covers a typical single-system home; it moves with system size, a second or third system, and how much accessible damage has to be repaired first, since sealant closes gaps but not a disconnected run. 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 (aerosol) 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.
