    Kevin Sweeney came out to look at our front porch which I thought was going to be able to be replaced and actually is a more complex job than just ripping it out and putting something else in .. he was very honest with me and said because we have pavers which is something that they don't specialize in and was kind enough to point me in the right direction to someone that can do that type of work. I really appreciated the honesty and in the future if I do have any concrete work I will definitely reach out to him based on his honesty.

    I agreed with said company to have wall anchors installed in my basement, installation included a 3 year service contract. Installation was completed in July 2025. A deposit was made at the time of contract creation and balance of payment due was made it full at the time of completion. Said company came out on april 11, 2026 to maintain installed wall anchors and determined one anchor was improperly installed/not connected outside and would require additional service involving digging up the existing anchor and re-attaching it. I have repeatedly called to schedule the needed service, but the company either does not return calls or simply does not answer the phone. When I was able to actually talk with a rep, they scheduled service twice and have failed to show up for either instance. I tried to follow up after the second missed appointment and now they are no longer answering calls or responding to text messages. I have attempted repeatedly, through various means and phone numbers to resolve this issue to no avail. I would avoid this company if you are considering having basement/foundation work done.

    Our project began on July 6, 2026 and we’re told it should be completed in 2 weeks, including the drywall being put up, painting, etc. it is now October 3rd, still need completion. Now, basement Authorities work was completed in a timely manner, however, there demo crew, as we found out from the drywallers caused them to do more work. The demo crew also cut into some electrical wires, now we needed an electrician above what we thought we would need. Our salesperson told us the we can do 2 years, no payment, no fees if we complete payment within the 2 years. We opted for that. Imagine our surprise when Basement Authority showed up the first day and couldn’t begin until we made the first payment. Our salesperson was shocked! He was unaware of that, we felt we had been a bit scammed. The list goes on, I’ll stop here.

    Google reviews are not to be written by employees but that is exactly what is going on. All of these reviews with full names are made by employees of Groundworks which is the parent company of Ohio Basement Authority. Our 25,000 mistake was to take a look at the review from the Better Business Bureau which gives it an A+. We FAILED in spades to read the actual reviews. Go to BBB for Virginia and READ the actual reviews for Groundworks. Same with Ohio Basement Authority. My elderly parents contracted to have structural damage taken care of. We presumed the guy who did the assessment had a structural engineering degree. Not the case at all. Before you allow any Ohio Basement Authority representative on the property, google their full name. Ask about their degrees and professional qualifications…a “certified field inspector” as they call themselves is an in-house label used to deceive people about their non-qualifications. They financially exploited my elderly parents, failed to follow-up, and the work that was done relapsed within six months. They ruined my parents property including the driveway, the brick house, block windows, fencing and the most important part....the house became destabilized within 6 months. Reported in September 2025 but they said no inspections occur until November. In December they sent CJ out to inspect and said they would repair it. Never happened The initial salesman Jake/Jacob didn't have a degree in structural engineering and Joel Went to Kent for music. They told my parents they needed work done that they didn't. We presumed when it comes to major structural work that the assessors will have college degrees in engineering. Google every person you speak with at Ohio Basement Authority as they train in-house which does not make them engineers. Instead it is fraudulent representation. Within six months the driveway was cracking and buckling, the cracks they made in the brick part of the house were getting worse, and the addition (which is what was sinking) went back to sinking to the point the door wouldn't shut. They sent CJ out in December who agreed it was sinking. Never heard from him again. Then in February another guy, Joel, came out and we asked why the work hasn't been scheduled and he said the other guy is no longer with them....well the reviews say differently. Joel was there only to do the annual inspection which is a fancy name for a sales call to try and sell unneeded services. He tried to get us to buy more services which after paying 25,000 for work that has basically ruined my elderly mothers property we were not going to buy more of the same. This was last February. We were told that Aaron was the only one to talk with about scheduling and that he would reach out. He didn't. Joel R made it clear that once we said we weren't going to pay for more services that he was done with whatever fake inspection he did. The lifetime contract was not honored, they didnt reply to any emails, and a year after reporting this we got a lawyer....then the calls and email came. This is a fraudulent company that took financial advantage of my elderly parents and is a pattern that is very consistent when you read the reviews on the BBB. Again, anyone you speak with ask them to prove their “certifications” (not the in-house sales based nonsensical certification) but professional accredited certifications and the degrees they have allowing them to determine structural needs of a house. Unfortunately the company seems to spend most of its time working on fake reviews to boost their poor image. The A+ rating through the Better Business Bureau is because they have answered every complaint and there are over 700 to read. They will try and sell you services you don't need and they will not be honoring the contract. Damage was done throughout the property, unnecessary work was done, and within six months it was obvious we were scammed. Don't trust the words of any employee but instead google them to find out their qualifications. Dont believe any reviews with a name in it.

    Edit as of Sept 17, 2026. After posting a review and emailing, another employee called me Tuesday Sept 15 to apologize for the lack of communication and offered to come out this Friday or Saturday to look at the basement. He stated he would call me back the next day (Wednesday Sept 16) to confirm time. As of Thursday Sept 17 at 6:30 pm, still no call and my voicemail is unanswered. So I’m sure the apology for the lack of communication was sincere since he is doing the same thing everyone else has done - apologized and then ghosted me. This company will over promise and under deliver every time. Original Post: We hired this company in June 2025 to complete basement waterproofing (including vapor barrier, interior drainage, sump pump, exterior concrete sealing, exterior concrete lifting). Unfortunately, since the work was completed, we have continued to experience intermittent water intrusion, and we are now also dealing with what appears to be a failing sump pump. The vapor barrier is nothing more than a mold cover… one wall has vapor barrier and the adjacent wall does not. The mold is spreading from the wall with the vapor barrier to the wall without the vapor barrier. Each time it rains, we have water coming in around a stoop on the side of our house and each time the sump pump attempts to run it trips the GFCI and relies on the backup battery. Additionally the sump pump now has a constant siren/alarm that goes off nonstop unless you leave the battery in the machine unplugged. Which consequently means this pump will not work and will not pump the water out of my house. On August 3, we had someone from the company come out to inspect the situation. After evaluating the problem and attempting to seal up additional exterior areas, he requested that his manager come out as well. The manager came out on August 21. At that visit, we were promised that by the manager that he would personally contact us within a few days (that following Wednesday August 24) to arrange the necessary repairs. They proposed resealing the stoop, fixing how the stoop is attached to the house behind the siding and adding additional drain footage in the basement to tie into the sump pump. It has now been three weeks since that promised phone call, and we have still heard absolutely nothing from the company other than a text message saying they can’t find a siding guy (see attached image). Today is September 14, and despite repeated attempts to get a response, we have been unable to get anyone to return our calls or provide us with a schedule for addressing the water intrusion and sump pump issue. I called the corporate office in Twinsburg two times. I spoke with two additional employees who both stated they would get someone in contact with me and they have failed to do so. The man I spoke with on Friday September 11 promised to call me today, Monday September 14, and as of 6:30 PM September 14. I have not received a phone call. The most frustrating part is that this is not a minor cosmetic issue. This is an issue that will affect the structural parts of my home and is also a mold breeding ground. We paid for professional waterproofing specifically to prevent problems like this, and we are now left with continued water coming into our basement and a system that needs attention—with virtually no communication from the company. Problems can happen with any installation, but what matters is how a company responds when something goes wrong. The lack of communication, follow-through, and urgency has been extremely disappointing. We should not have to repeatedly chase a company to get a response about repairs to work that we already paid for. At this point, we simply want the company to stand behind its work, the warranty, the product you sell, communicate with us, and schedule the repairs that we have been waiting weeks for. Based on our experience, we are very disappointed with both the service and the customer support after the sale. I would not recommend this company solely based on how you are treated if you have a problem.
