Permanently Waterproofing and Sealing a Nasty Crawl Space in Lancaster, OH

Tuesday, October 17th, 2017 by Holly Richards-Purpura


While many homeowners tackle improvements before moving into their homes, it’s never too late to create a healthier and safer living environment.

They have lived in their house for less than one year, but homeowners in Lancaster, OH, recently began to question the condition of their living environment, specifically the area under their home. The owners never ventured into the crawl space, but they recently discovered an access point in a closet to this area under their house. Once they peeked inside, they found standing water in the vented crawl space, as well as the lack of insulation.

After observing these nasty conditions, the homeowners were motivated to address these problems. As they began to research how to do this, they saw Ohio Basement Authority’s TV ads which prompted them to contact us for assistance. They met with Inspector John Dean, who completed a thorough evaluation of the crawl space. After discussing his findings with the owners, as well as their goals, John then presented the owners with our reliable crawl space repair solutions.


Foreman Jose de Jesus Tellez Ortiz then led his crew in waterproofing and encapsulating the crawl space.

The crew first installed the CrawlDrain drainage system in the floor along the crawl space perimeter. This special drainage system is designed to accept seeping water from the crawl space walls and floor. This water is then directed to the SafeDri Pro sump pump to be pumped out of the crawl space.

Additionally, a FreezeGuard was attached to the exterior sump pump discharge line. This special attachment allows draining water to continue to escape the discharge line if the line freezes or becomes blocked. This line also was tied into a new downspout conductor line that was installed in the ground. A YardWell was placed at the end of the line to camouflage it in the yard.

Next, the crawl space was sealed with thick and durable CrawlSeal liner, which is similar to swimming pool liner. This liner completely isolates the crawl space from the earth, prevents moisture and vapor intrusion, and helps insulate the crawl space. The crawl space was further insulated with spray foam that was applied to the band joists. This area also was further sealed from outside air, precipitation and pests by placing vent covers over the vents. A door also was installed to replace the former exterior access door.

The homeowners now have peace of mind knowing these trustworthy repairs have helped them create a safe and healthy crawl space and home.
