After experiencing water in our basement 4 separate times in a single month, we called Ohio Basement Systems and they promptly returned our call and scheduled a visit within 3 days. We were impressed by the company’s lifetime transferable warranty. We were able to schedule the work within 2 weeks and we’re fortunate to have the very professional and knowledgeable crew of Rashawn, Ovid and Cody. They were a pleasure to work with and our dog is really going to miss them!

Ohio Basement Systems were super professional, courteous, price effective, and friendly. Darin DeRosa not only explained things plainly but did not push other services that we did not want. He was also very patient, knowing we were going through a refinance.The crew that came out to do the job actually called when they were running a little late, which was very nice. They did great work, were friendly and cleaned up completely after they were done.A+ to all involved!

We worked with multiple teams from Ohio Basement Systems to resolve the foundation problems on our century home. All teams were communicative, professional, on time and conscientious about the work they were doing to our home. I didn't expect so much professionalism at every point. The teams included: Kevin Townsend, Robert Baser, Rashawn Dickson and their teams: Dylan, Matt and Ovid.

Brian Kingsmore from Ohio Basement Systems came out and did an evaluation and estimate for basement waterproofing for my home. He was extremely thorough in his explanations of the different options for my home. After he left, I felt like I understood why the water problem in basement even exists. Thanks Brian!!
