Duct Sealing (Mastic, Accessible Runs) in Schertz, 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 Schertz (3 ZIP codes, 42k residents) and surrounding neighborhoods with same-week scheduling.

Local dossier · Schertz, TX
Schertz is unusual in two ways that matter for ductwork. Almost every home is detached single-family, with very little attached or stacked housing anywhere in the city, and almost every one of them heats with electricity rather than gas. That means no flue, no heat exchanger, and one cabinet doing all the work: blower, evaporator coil, filter rack and strip heaters in a single box that is where nearly every real air-quality issue in this city begins. It also explains the burning smell people report on the first cold morning, which is dust scorching on the heat strips rather than a failure. The other local factor is turnover. With Randolph and the wider joint base next door, houses here change hands and tenants often, and a system inherits whatever the last household did to it. We find that history in the cabinet before quoting anything.

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.
