Duct Repair & Sealing in Charleston, WV
In a typical house, 20–30% of the air moving through the ducts leaks out. In a 140°F Las Vegas attic, that leak means paying to cool the attic. A duct leakage test finds out how bad it is, then techs repair the disconnects and seal the joints with mastic or an aerosol sealant.

Duct Repair & Sealing in Charleston: what's different
Duct Repair & Sealing in Charleston is shaped by local conditions. Damp basements: River-valley humidity and older foundations keep basements damp, which rusts furnace cabinets, corrodes flue pipes and feeds musty air into return ducts.
Older homes often have basements with gas furnaces or converted boilers and ductwork added decades after construction. Hillside lots mean outdoor units sit on retaining walls or steep yards, and river-level neighborhoods in Kanawha City and the West Side deal with damp basements. For duct Repair & Sealing, that means the contractor should start with inspect and test and confirm what is actually installed before quoting. Another local pattern worth mentioning to the tech: retrofitted ductwork. Ducts added to older homes are often undersized or snake through tight chases, leaving upstairs rooms hot in summer and cold in winter.
The City of Charleston issues mechanical permits inside city limits; Kanawha County handles unincorporated areas. Furnace work books up after the first October cold snap, so schedule heating checks in September.
