After my basement flooded from a drain back up, in July of 2023, and Pure Clean Water Removal Company with excellent results, dried my basement and noticed some mold in the corner, I called Ohio Basement Systems, and set an appointment with Joel Rhoads within days. I also called Ohio State Waterproofing and it took 2 weeks for an appt. To make a long story short, Joel Rhoads, an honest man that he is, advised to try a water backup plug that lets water drain, but it also plugs backup water from back flowing from a heavy rain. I only had water backup twice in 35 years. I never had actual water seepage through the foundation blocks. He also advised lifting the concrete, because it sunk a little from the outside corner where the mold was, and digging to waterproof that corner. On the other hand, Ohio State Waterproofing Co, with all their bells and whistles tried selling me their complete system, for an absorbent amount of money, and it was all (inside AND outside) or nothing for water seepage that I never had. All I may have been interested in was just outside waterproofing the foundation in that corner. I’m the type of person who tries by baby steps first. In this day of age, it is so hard to trust anyone, and to have come across Joel Rhoads, was a blessing. I believe he saved me a ton of money! I sincerely recommend Joel from Ohio Water Basement Systems for his honesty over greed.

Ohio Basement Systems sent Kevin out to look at our basement to see what we needed to do about our mini flooding. He was so professional and was able to get us financed at a reasonable rate and payment plan.The team of professionals they sent to do the job was so professional, understanding, and seemed like genuine people to have in your home. I was thoroughly impressed with their work. They work very well as a team. They are super respectful. They speak and greet you with a smile. They were fast and efficient. They even cleaned up after themselves. They were patient with explaining everything so I understood what their job entailed. They did such good work and I was so pleased I wanted to rave about their service.If you are needing anything done Ohio Basement Systems is your company, and be SURE to request by name the team of: Sean, Justin, and Ferro. They are a really, really, a good team. Since I have owned my home for a year their team work and presence was the best I have had in my home thus far. God forbid I need anything else done I am definitely be requesting them by name.

Your technician Chris Shewell did the annal maintenance inspection for our basement waterproofing system installed last year. He was very thorough and set up the air system for a more efficient flow and relocated the control panel to a more convenient location on top. He explained how the air system could be put in an enclosure with ducting if we so desired. He told me the average life span I could expect for the pump backup battery and a replacement during the warranty period needs to be done by OBS to insure proper installation. Very appreciated information. We were quite pleased with the 5 star service he provided. Scott and Joanne Krebs

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!

The business was responsive to my needs, communicated clearly and promptly. The team (Wynn and Mike) that did the work was efficient and thorough. They told me what to expect (noise, time). They did the work then explained it to me in a way that I can understand. They cleaned up and left the place cleaner than it was before. Wynn and Mike did an excellent job, I am glad that I went with Ohio Basement Systems.
