We handle crawl space encapsulation for Downers Grove 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.

Good to know
Crawl Space Encapsulation in Downers Grove, IL: 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.
Is the crawl space encapsulation you do in Downers Grove to a real standard?
Yes. Our crew follows the IICRC S520 standard for mold remediation, the same framework insurers and inspectors recognize across DuPage County.
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.
Will my insurance cover crawl space encapsulation in Downers Grove?
It depends on the cause. When the mold follows a sudden, covered event, there is often coverage. We bill your carrier directly and document the loss so your Downers Grove claim moves.
