Good to know
Crawl Space Encapsulation in Deer Park, WA: 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.
Do I need to leave my Deer Park home during the work?
Usually no. We seal the work area under negative air, so most of the Deer Park home stays livable. For larger jobs we will tell you if it is better to step out for a day.
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 Deer Park?
We answer our line 24/7 and can usually reach a Deer Park home the same day you call, sooner for an active leak.
