Job Stories From De Graff, OH
Keeping a Leaking Bank Basement Dry in De Graff, OH
As the managers of a bank in the Village of De Graff, OH, they wanted to make sure employees and customers would have a safe and healthy business environment. The basement of the building is used for storage, and the managers recently noticed evidence of water intrusion and damage. The managers started to research how to address these problems, and they came across Ohio Basement Authority’s website. They were eager to contact us to meet with one of our inspectors and learn more about how we could help them. After evaluating the condition of the basement, our inspector recommended some of our reliable basement waterproofing solutions. One of our crews then installed the BasementGutter interior drainage system, replaced the older sump pumps with the SafeDri Battery Backup System, and installed a dehumidifier. Any seeping water from the walls and floor will be intercepted by the BasementGutter system and directed to the SafeDri sump pumps. Each system features two powerful pumps inside the liner, as well as an external backup battery that ensures the systems will always operate to pump water out of the basement. The dehumidifier will clean and filter the air, control moisture and humidity, and prevent odors and potential mold growth. The managers are pleased these trustworthy solutions were installed to keep the property dry and healthy for many years to come.

I decided to go with Ohio Basement Authority because of the information online. Everything was easy to find and easy to understand due to the presentation and content of the site.

The foreman, Jose, went over everything with me before the crew started. After that, they immediately started working and worked nonstop until the end of the day. I told Jose that I was impressed with the clean-up. They left my yard just as I had it.

The crew was very courteous. The foreman introduced himself and explained what they would be doing. They got right to work and did a great job. The cleanup was meticulous. They even wiped the support beam down. I am very happy with the product so far, and the crew was a very hard-working group of guys.
