Duct Sealing (Aerosol) in Round Rock, 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 Round Rock (6 ZIP codes, 120k residents) and surrounding neighborhoods with same-week scheduling.

Local dossier · Round Rock, TX
Round Rock carries more attached and rented housing than the Williamson County towns around it, and that shifts the practical advice. If you are in a townhome or apartment here, the duct is not yours to modify, but filter size, filter schedule and reporting a sweating vent or a whistling return grille are, and those three account for most of the improvement actually available to you. If you own a detached house, the odds are it was built in the 2000s, which puts the system at roughly two decades: old enough for a first genuine inspection, young enough that the answer is frequently that nothing needs cleaning yet. What we find in that vintage is fairly predictable, flex sagging between straps, a coil nobody has ever opened, and a return undersized for whatever equipment the last contractor installed. Only one of those three is fixed by cleaning duct.

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.
