CrawlSeal, ExTremeBloc, & Dehumidifier Improve the Health of a Crawl Space in Worthington, OH

Tuesday, May 28th, 2019 by Holly Richards-Purpura


After living in her house for 30 years, a homeowner in Worthington, OH, began to experience health issues due to the air quality in her home. Along with the bad air quality, she also noticed a foul smell. This was because the crawl space was in extreme disrepair. It leaked during heavy rains, resulting in puddling near where the bottom block and footer meet.

She contacted Ohio Basement Authority because she was concerned about her breathing problems and cold floors. She said she selected Ohio Basement Authority because of its professionalism and good ratings on Angie's List.

Inspector Matthew Wojciechowski found damp, fallen insulation, an inadequate vapor barrier, and lots of moisture and mold growth.


It was an extensive project, but the crew completed it within two days. It took a lot of work to remove the deteriorating fiberglass insulation and clean up the area.

The CrawlDrain drainage system was installed around the perimeter of the crawl space. It led to a SafeDri pump, which was also installed. Then CrawlSeal liner with drainage matting was then placed on the floor. The drainage matting allows any water to flow to the CrawlDrain and SafeDri, and the CrawlSeal liner completely encapsulates the area, keeping the surface dry.

ExTremeBloc insulation panels were installed on the walls, and a dehumidifier was installed to help eliminate damp, musty odors. Several vent covers were also installed to keep excess moisture out of the crawl space.

These products provided a complete solution to the homeowner's issues because they isolate the earth, eliminate moisture, fix the ground water seepage problem, improve the air quality, and help with energy savings. The crawl space is truly sealed, and the products have Lifetime Transferable Warranties.

The homeowner is ecstatic and loved the quality of the work in her totally transformed crawl space.
