Upon moving into their house in Granville, OH, homeowners noticed the partial crawl space adjacent to the basement was not finished. Even though it was insulated, the fiberglass insulation and plastic liner was beginning to fail.

The owners would like to finish the basement area and use it for storage, so they were eager to improve the health and function of the crawl space before moving on to other projects. After seeing a commercial for Ohio Basement Authority on TV, the owners knew they had to call us.

After removing the older insulation and liner, the crawl space was encapsulated in durable CleanSpace liner. This thick liner is similar to pool liner, and it completely isolates the home from the earth. It also prevents moisture and vapor intrusion and helps insulate the crawl space. CleanSpace is tough enough to crawl on, and it automatically brightens and improves the appearance of the crawl space.

The homeowners now have peace of mind knowing this permanent solution has created a healthier and more functional crawl space they will be able to enjoy for many more years to come.

Vicinity of Williamson Rd. in Granville
My home is 7 years old and has a walkout basement. We've never had any water in the basement until last Monday. I've had two contractors (working on an unrelated project) and a builder (from new construction next door - not my builder) here investigating possible reasons for my problem. There has been a lot of new construction in the area, and perhaps the water table has been affected. Regardless of the cause, the best solution at this point may be to install a sump pump.
