Our crawl space had a musty smell for as long as we've owned the house. The team removed the mold that was there and encapsulated the whole space, and they were careful to work around our radon vent pipe the whole time.

We handle crawl space encapsulation for Fountain Valley the right way. We find and fix the moisture source first, because mold always returns if the water problem is left behind, then we contain the area and remove the mold safely.
Our team is based in Corona Del Mar, about 15 minutes from our Corona Del Mar base, so we can usually reach a Fountain Valley home the same day. Our methods follow public guidance from the EPA and the CDC on handling indoor mold safely.

Good to know
Crawl Space Encapsulation in Fountain Valley, CA: common questions
Do you remove existing mold before encapsulating?
Yes, encapsulating over active mold growth doesn't solve the problem. We remove and treat existing mold first, then install the vapor barrier.
How long does crawl space encapsulation take?
It depends on the size of the crawl space and how much remediation is needed first, but most projects are completed within a few days.
Is my crawl space a good candidate for encapsulation?
Dirt crawl spaces with recurring moisture, musty odors, or visible mold on framing are typically good candidates. We can assess yours during an inspection.
How do you keep the mold from coming back after crawl space encapsulation?
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 Fountain Valley home.
Will encapsulation affect my radon mitigation system?
No, we coordinate the vapor barrier installation carefully around existing radon vent piping so the system continues working as intended.
Does encapsulation stop mold from coming back?
It significantly reduces the ground moisture that feeds mold growth, which is the main reason crawl spaces develop recurring problems.
How soon can you start crawl space encapsulation in Fountain Valley?
We answer our line 24/7 and can usually reach a Fountain Valley home the same day you call, sooner for an active leak.
Do you serve Fountain Valley?
Yes. We cover all of Fountain Valley, including Huntington Beach, Garden Grove, Westminster, and the rest of the Fountain Valley area. We are based in Corona Del Mar, about 15 minutes from our Corona Del Mar base, and answer our own phone around the clock.
