Doug Secrest, from Ohio Basement Authority, explains what work was done to this crawl space to get rid of excessive standing water, mold and mildew. To combat the crawl space moisture problems we installed an interior drainage system with perforated holes to allow proper drainage to the sump-pump. The water channeling to the sump-pump will pump the water up and out of the home, keeping the crawl space dry and functional for the home.
