We had a musty smell coming up through the kitchen floor for a while and finally had the crawl space checked. The vapor barrier had torn in a couple spots and mold had spread along several joists. They removed it and were careful around our radon system the whole time.

The crew showed up on time, contained the work area, and showed me the moisture readings before and after. Tidy, careful work.
Happy with the remediation. Would have liked a quicker callback, but the crew did excellent work.

Good to know
Crawl Space Mold Removal in Hidden Hills, CA: common questions
How do I know if my crawl space has mold?
The most common sign is a persistent musty smell in the rooms above, especially near the floor. Discoloration on exposed joists, if you can see into the crawl space, is another clear indicator.
Do you install vapor barriers?
We assess vapor barrier condition during inspection and can perform full crawl space encapsulation as a separate service if your space needs more than mold removal alone.
How long does crawl space mold removal take?
Most jobs run one to a few days depending on the size of the space and how much wood is affected. Low clearance can slow the physical work down even on a relatively small area.
Do I need to leave my Hidden Hills home during the work?
Usually no. We seal the work area under negative air, so most of the Hidden Hills home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Is it safe to work in a crawl space with a radon system?
Yes, our crew works carefully around existing radon mitigation piping, sealing, and fan units. We won't disturb an active system, and we'll flag anything that looks compromised.
Can crawl space mold affect the air I breathe upstairs?
It can, since air moves between a crawl space and the living area above through gaps, ductwork, and flooring seams more than most people realize. That's part of why persistent odor complaints often trace back down there.
How do you keep the mold from coming back after crawl space 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 Hidden Hills home.
Do you serve Hidden Hills?
Yes. We cover all of Hidden Hills, including Calabasas Highlands, Agoura, Topanga, and the rest of the Hidden Hills area. We are based in Oak Park, about 10 minutes from our Oak Park base, and answer our own phone around the clock.
