This Union County, NJ crawl space had water seepage on one wall. The moisture in the crawl space was a huge problem in this home due to the stack effect. The stack effect refers to air from the bottom of the home traveling through the rest of the house and out of the attic. The musty air was in all areas of the home. Quality 1st Basement Systems treated the leaking crawl space with CleanSpace vapor barrier and a waterproofing system. The crawl space is now dry and healthy!
