Air Duct Mold Removal in Houston, TX

What air duct mold removal actually involves in Houston

Houston attics stay humid for most of the year. That matters more than anything else here. Insulated flex duct has a torn or stapled-through outer jacket. Humid attic air reaches the cold inner core. Condensation forms inside the insulation. Growth follows at that one spot, not through the whole system.

So we look where moisture lands first. Plenum seams and boot connections at ceiling registers. The first few feet off the air handler. Drain pan overflow leaves a stain down the plenum, and that stain tells you the coil is the source. Cleaning branches while the coil is loaded is wasted motion.

Galvanized trunk lines in older homes hand-brush fine. Fiberglass ductboard plenums from the sixties through eighties often do not. Once the interior surface has eroded, growth sits down in the fiber and no brush reaches it. That section gets cut out and rebuilt off-site or replaced, not scrubbed.

Work is done under negative pressure so debris leaves the house. Flex interiors get agitated. Registers and boots come off and get washed separately. Then the leaks get sealed. Unsealed attic access panels and open chases pull blown-in insulation straight into the return.

Fogging a sanitizer over damp fiberglass accomplishes nothing. Fix the water path or it returns.
