I just had a gentleman, Jordan Moses come to my house because I have water seeping into my basement. I was so very much elated and impressed that he was totally honest with me. He could have written up an estimate ($$$) for me to waterproof my entire home, like others I've called have done. But instead, he checked things out and told me that the problem is a sewage issue, most likely a broken pipe, thus explaining the gray matter and the odor. No other company even mentioned this, they just wrote up a very expensive proposal for waterproofing, that is not at all necessary. Kudos to Ohio State Waterproofing and thank you Jordan for driving all the way out here and being so honest!!
