Air Duct Mold Removal in San Mateo, CA

Air duct mold removal in San Mateo homes

San Mateo crawlspaces stay damp most of the year. Marine air sits under raised foundations near the creeks and baylands. Bare galvanized trunks sweat in that air. Growth shows up on the duct exterior first, then at boot connections where the metal meets subfloor. Most calls we take are this, not interior growth.

So the first job is diagnosis, not fogging. We look at where moisture came from. Sagged flex off its hangers holds water in the belly. Rodent-torn jacket lets crawlspace air into the liner. A panned floor-joist return pulls straight from the crawlspace because it was never sealed. Clean a duct with the source live and it comes back.

Fiberglass liner and flex that have grown through cannot be cleaned. Porous material gets replaced. Hard metal gets brushed, vacuumed under negative pressure, then treated with an EPA-registered product labeled for HVAC surfaces. Blower wheel and coil face matter too, since spores settle there.

Asbestos tape on 1920s-40s octopus trunks is common here. That is abatement work, not duct cleaning, and we stop and say so.

Ask any company to show you photos before and after, and to name the moisture source. If nobody can name it, the mold is coming back.

What Happens After You Call Us

Step 1

Call and tell us what you're seeing, dust on the registers, weak airflow in the back bedrooms, a dryer that needs two cycles. We book a two hour arrival window and text you when the van is twenty minutes out.

Step 2

We open the furnace closet, pull a register or two, and look at the crawlspace or attic runs first. The estimate is free, and you get one firm number for the supply and return count we actually find.

Step 3

We clean the lines, check airflow at each register, vacuum up anything we tracked in, and show you before and after photos. You pay the number we quoted, even if the crawlspace runs longer than expected.
