Job Stories From Islip, NY
Wet Crawl Space Repair in Islip, NY

This homeowner in Islip, NY had a crawl space that would leak whenever it would rain a lot outside and also had humidity rising up from the dirty and into their crawl space creating a very wet/ humid environment so they gave us a call to come encapsulate their crawl space. Our team came out and was able to make this crawl space completely dry and usable by encapsulating this crawl space with our CleanSpace vapor barrier, our team first put down a layer of draining matting over the dirt of the crawl space and this will help separate the earth from the crawl space while still allowing water to flow underneath it. Our team then put our vapor barrier over the drainage matting which will prevent any water and moisture from rising out of the ground and entering the crawl space, making the space completely dry and usable. To make sure this crawl space remained completely dry we installed our dehumidifier in the crawl space which will filter out any mold and moisture that might be in the air and self discharges that moisture back outside, so you as the homeowner never need to worry about emptying your dehumidifier. Since crawl spaces are normally nasty and dark our vapor barrier system is bright white to help make the space brighter and cleaner, now this homeowner has a crawl space that is completely clean, dry, and usable for many years to come.
