Air Duct Mold Removal in San Mateo, CA

What air duct mold removal involves in San Mateo

Winter fog sits in these neighborhoods for days. Under 1940s-60s ranches, the original galvanized trunk runs through an open crawlspace. Uninsulated metal gets cold. Humid crawl air condenses on it. Mold does not eat sheet metal. It eats the settled dust film on top of it, and that film is thick here after a six-month rainless season.

So the first job is finding the water. Disconnected or sagging flex at a boot pulls raw crawl air into the system. A missing vapor barrier over bare soil feeds the whole space. A coil pan that drains slow wets the supply plenum. Bay-adjacent slab tracts with attic distribution have their own version, usually summer condensation on cold flex.

Bare metal and rigid board respond to mechanical cleaning: agitation, contained negative pressure, then inspection. Porous fiberglass flex liner is different. Once growth is in the liner, scrubbing it shreds the material. That run gets replaced, not cleaned.

Fogging a disinfectant through dirty ducts is the shortcut we avoid. It masks odor and leaves the dust. If the moisture source stays, growth returns within a season, and you have paid for a reset instead of a repair.

What happens after you call us

Call us and tell us what you're noticing, dust on the registers or a weak push of air. We'll give you a two hour window instead of an all day wait, and the estimate is free.

We show up, open a few registers, and look at the trunk line before we say a number. The quote is firm and depends on your runs, the age of the branches, and the buildup.

We seal off the rooms, clean the runs and the return, then check the airflow at each register with you watching. Your floors get swept, and you pay the quoted number, not a dollar over.
