After one year of owning their vacation home, homeowners in Nelsonville, OH, began to notice various issues such as cold floors and water collecting in the crawl space. These issues can lead to an uncomfortable and unhealthy atmosphere within the home.

The owners wanted to be sure this home away from home would be a safe and healthy living environment, so they contacted Ohio Basement Authority after learning more about our crawl space repair services online.

We completely transformed this unhealthy area underneath the home by installing several of our reliable crawl space repair products.

The crawl space was encapsulated in CleanSpace liner, which acts as an insulating water and moisture barrier. This liner is also compatible with the SmartSump sump pump that was installed to pump any seeping water out of and away from the crawl space. Spray foam insulation also was added to the rim joists for extra insulation.

The sump pump discharge line was tied into a new downspout conductor line. Exterior vent covers were also placed over the vents to prevent pests, outside air, and precipitation from entering the crawl space.

The homeowners were excited these various permanent solutions were installed so their vacation home will be a healthy place to visit for many years to come.

Job Stories From Nelsonville, OH
Waterproofing a Leaking Basement in Nelsonville, OH

While they have lived in their house for only a few months, homeowners in Nelsonville, OH have already experienced some problems with the home. Water was seeping into the basement and attached garage at the wall-floor joint during heavy storms. This resulted in several areas of puddles that they were constantly cleaning up.

Tired of worrying about this every time it rained, the homeowners wanted to fix this problem once and for all. They found information about Ohio Basement Authority online and they were eager to contact us to learn more about how we could help them. They met with one of our inspectors who completed a thorough evaluation of the leaking basement and garage. Our inspector then recommended some of our reliable basement waterproofing solutions.

One of our crews then waterproofed the basement and garage with the WaterGuard drainage system and TripleSafe sump pump. WaterGuard is placed in the sub-floor to catch any seeping water from the walls and floor. This water is then drained to the TripleSafe sump pump. The TripleSafe is equipped with three powerful pumps inside a large liner, as well as an external backup battery.

Additionally, IceGuards were attached to the exterior sump pump discharge line, and LawnScapes were used to camouflage the ends of the exterior drainage lines in the back yard.

The homeowners can rest easier knowing these trustworthy repairs will keep their basement dry for many years to come.

Sealing a Nasty Crawl Space in Nelsonville, OH

Maintaining a safe and healthy vacation home away from home for their family is very important to homeowners who frequently say at their log cabin in Nelsonville, OH. After owning the home for about one year, the owners began to notice problems with the dirt crawl space underneath the house.

This area was very wet from taking in a lot of water during heavy rains, and it was filled with debris and failing insulation. This concerned the homeowners, and they wanted to address these issues right away. They were eager to contact Ohio Basement Authority after learning more about our company online. After meeting with one of our experienced inspectors, the owners were equally excited for one of our expert crews to transform the nasty crawl space.

After removing the debris and other nuisances from the crawl space, we encapsulated the area in CleanSpace liner. This thick and durable liner completely isolates the crawl space from the earth, acts as a moisture and vapor barrier, and helps insulate the crawl space.

Additional installations included the SmartSump sump pump that replaced the portable sump pump the homeowner previously installed, spray foam insulation that was applied to the band joists, and exterior vent covers to further seal the crawl space from outside air and precipitation.

The homeowners now have peace of mind knowing these reliable permanent solutions have not only improved the health and appearance of the crawl space, but the health of the home as well.

Need crawl space sealing/waterproofing.
Vicinity of Bessemer Rd. in Nelsonville
We have a semi finished basement that with heavy rainfall water seeps in where floor and wall meets. Our basement has drywall up and I haven't seen any wet dry wall so not sure if leaking in anywhere else but it for sure does at bottom on floor. And occasionally in odd spots on floor. Has happened in different areas of the basement so not sure if it is fixable without a definitive spot where coming in but there is one area that it does the most. Also a garage under the house does leak as well but more concerned about the living area of the basement right now. Just a little bit stressed every time it is supposed to rain and know it will rain this week and next week according to forecast and ground is already so wet.
