Same-day response when our basement flooded. They dried it out and removed the damaged drywall before mold could spread.
Fast response when we discovered mold in the attic. Remediation was done in two days and the air test came back clean.
Our process
Our basement mold removal process in San Diego, CA
Inspect
We check foundation walls, the sump pit, and window wells for the moisture path, not just where mold is visible.
Contain
The basement is sealed off from the stairwell and upper floors before any material is disturbed.
Remove
Affected drywall, baseboard, and framing come out; masonry and concrete are cleaned and treated in place.
Dry
Air movers and dehumidifiers run until the space hits a safe moisture reading, not just until it looks dry.
Verify
We recheck moisture at the original problem spots before finishing, since basements can hide slow seepage.

Good to know
Basement Mold Removal in San Diego, CA: common questions
Is basement mold dangerous if the basement is unfinished?
Unfinished basements aren't automatically safer, they're just easier to inspect. Mold on concrete, framing, or stored items still needs to be addressed, especially if there's an active moisture source.
How do I know if my basement mold is from spring rain or a pipe leak?
Location is the biggest clue. Mold concentrated near foundation walls or window wells usually points to outside water; mold near a water heater, laundry area, or overhead pipe usually points to plumbing.
Do finished basements cost more to remediate?
Finished basements typically involve more removal, drywall, flooring, framing, which adds time and material compared to an unfinished space. We'll give you a specific scope after inspection.
Do I need to leave my San Diego home during the work?
Usually no. We seal the work area under negative air, so most of the San Diego home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Can you fix the water problem, not just remove mold?
We identify likely sources like foundation cracks or drainage issues and explain what we're seeing, but structural repairs like crack sealing or grading are outside our scope. We can point you toward what needs attention.
Will you move stored items out of the basement?
We'll help clear the immediate work area as needed. Heavily contaminated porous items like cardboard boxes or old carpet often can't be salvaged and we'll flag those before disposal.
How soon can you start basement mold removal in San Diego?
We answer our line 24/7 and can usually reach a San Diego home the same day you call, sooner for an active leak.
Do you serve San Diego?
Yes. We cover all of San Diego, including Coronado, National City, Chula Vista, and the rest of the San Diego area. We are based in Del Mar, about 30 minutes from our Del Mar base, and answer our own phone around the clock.
