Our sump pump failed during a spring melt and we came home to a wet, musty basement. They pulled up the affected carpet and drywall, dried everything properly, and explained why our window well needed better drainage.

Rated 4.9 by Newport Beach-area neighbors
Fast to respond and easy to reach. The technicians were tidy, respectful of our home, and explained what caused the growth so it would not come back.
Honest company. They told us the mold patch was small enough to clean ourselves and even explained how.
Our process
Our basement mold removal process in Newport Beach, 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 Newport Beach, 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.
How do you keep the mold from coming back after basement mold removal?
We fix the moisture source first, not just the mold, then dry the structure and recheck it. That is what keeps mold from returning to a Newport Beach home.
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.
Is the basement mold removal you do in Newport Beach to a real standard?
Yes. Our crew follows the IICRC S520 standard for mold remediation, the same framework insurers and inspectors recognize across Orange County.
Do you serve Newport Beach?
Yes. We cover all of Newport Beach, including Costa Mesa, Huntington Beach, Fountain Valley, and the rest of the Newport Beach area. We are based in Corona Del Mar, about 5 minutes from our Corona Del Mar base, and answer our own phone around the clock.
