Concrete Repair With PolyRenewal®!

If you have a concrete sinking problem, we also offer concrete leveling so you can enjoy your driveway, sidewalk or patio again without worry. In the past, contractors relied upon mud jacking (also known as slab jacking, concrete lifting, concrete raising, grout pumping and slab leveling) to level concrete that had settled over time. This entailed pumping concrete slurry under the settled slab to raise it and hoping that the settlement wouldn't continue. At Ohio Basement Authority we use PolyRenewal® because it is a fast & efficient method to raise sinking concrete. This simple foam injection can stabilize your concrete slab for years to come!

Job Stories From Williamsport, OH
Permanently Waterproofing a Leaking Basement in Williamsport, OH
After living in their house for three years, homeowners in Williamsport, OH, noticed water seeping into their finished basement. This was especially concerning because of the media room and workout areas in the otherwise pristine basement. The homeowners wanted to address their leaking basement and prevent any potential damage to their home. They were eager to contact Ohio Basement Authority after learning more about our company through our website. After one of our experienced inspectors completed a thorough evaluation of the home, the owners were equally excited for one of our expert crews to install several permanent basement waterproofing solutions. We installed the BasementGutter interior drainage system in the sub-floor to catch any seeping water. This water is then drained to the reliable SafeDri Triple sump pump, and from there it is pumped out of the basement and away from the home. Two FreezeGuards were attached to the exterior sump pump discharge line, and new downspout conductor lines were installed on the property. The owners now have peace of mind knowing these reliable repairs have helped them create a safer and healthier home that they will be able to enjoy for many more years to come.
Stabilizing and Leveling Sagging Floors in Williamsport, OH, with IntelliJacks
While they have lived in their house for almost 20 years, it wasn’t until the last few years that homeowners in Williamsport, OH, began to notice structural issues with their home. Several areas of the floor seemed to be sagging and unlevel. These issues could be the result of foundation settlement or improper supports beneath the floors. The owners wanted to fix these problems once and for all, so they began to research how to best address them. They contacted Ohio Basement Authority after finding information about our company online. They met with one of our inspectors who completed a thorough evaluation of the floors and the support system in the crawl space under the house. Several floor joists and shimmed colulmns were failing to properly support the above floors, so our inspector recommended one type of our many reliable foundation repair solutions. One of our crews then installed several IntelliJacks in the crawl space. IntelliJacks appear similar to typical jack posts, but they are far superior. These heavy-duty supports are made of galvanized steel, which enhances their durability and makes them resistant to rust, corrosion and rot. IntelliJacks permanently stabilize the above floors and offer the best opportunity to lift them back to level. They are designed to stop settlement, but can easily be adjusted if any settling occurs. The homeowners now have peace of mind knowing this trustworthy solution has helped them create a safe and stable living environment.

I looked online, and your website, along with others, came up.

The company representative I first met with was very professional and knowledgeable, and did a very informative presentation, answering all my questions.

I had already scheduled a job when I discovered that a rental unit that I am building and the dirt under it had settled. The floor was basically hanging in midair. I contacted my inspector, and he made sure the office got in touch with me. You found an open spot and scheduled both jobs the same day.

The installation crew was very prompt, went right to work, and was very professional and courteous. Mike explained everything he was doing, and never left me uncomfortable at any time. You need to hang onto this employee and his trainee!

The clean-up was also very thorough. They even cleaned up my mess, along with theirs.

I am very satisfied with every aspect of your operation – from the very first inspection to the last piece of dirt swept from my floor. I would and will recommend your service and product highly to friends and other customers.

Our inspector's honesty and helpfulness, as well as the guarantee on putting together a plan to fix our problem, were the main reasons we chose to work with Ohio Basement Authority. He was excellent and went through all the information and analysis of our water issues, helping us with our decisions. The great reviews from other customers online also solidified it for us.

The office staff also was very helpful and courteous.

I can’t say enough about the crew. They were on time every day, and I appreciated the courtesy calls letting me know they were on the way. They were very courteous and worked with me on making sure we had the best solution. We are very satisfied with the work from Milton, Daniel, and the rest of the crew. They cleaned up when they were done, kept the dust contained, and sprayed down the basement and driveway.

We are very satisfied with the end product and would recommend using your company to our friends, family and co-workers.

Your representative was very thorough and answered my questions both when he was here and later when I had additional questions. His presentation and willingness to work with me sold me on the job.

The crew called and told me when they would be here. But with the extreme cold and snow I asked them just to take their time and be careful. I think they may have been five minutes late, but it was sooner than expected in those conditions. They were extremely courteous and the work was very, very satisfactory.

The BBB rating and the extensive information on your website concerning French Drain systems and similar products/methods is why I chose Ohio Basement Authority. And I was surprised to receive a phone call less than an hour after I submitted my online inquiry. Very responsive. Matt did a great job explaining the process and products, and working within the constraints imposed. The crew was very courteous and friendly, and also took the time to explain as the work progressed. All company representatives that I was in contact with were very helpful, friendly and courteous. I appreciated how quickly my work was done, due to early wrap-up of another job. I am very pleased with the work.

I chose to work with Ohio Basement Authority because of the company’s reputation and the representative that I dealt with.

John was great. He was very thorough, explained the process well, and outlined my options without pressuring me. He was a big part of why I went with the system I did.

I’ve seen your commercials during the Channel 10 newscasts. Jacob did our inspection and was professional and friendly, and all of the crews surpassed our expectations. All three crews called an hour or so before arrival to tell us they were on the way, and showed up as stated. They all were courteous and told us what they would be doing, and continued to ask us if we had any questions. They all did as much as they could to keep things clean.

After hearing about Ohio Basement Authority on a TV commercial, I chose to work with the company because of the representatives’ promptness and the customer reviews. My inspector was awesome! He was courteous and very knowledgeable. And the crew was amazing! They would talk with me about what they were going to do and wanted to make sure I was 100% satisfied with everything they were doing. It was cleaner when they left than it was before they ever started the work.

I heard about Ohio Basement Authority on a TV commercial, and I chose to work with the company because of the BBB ratings alone. The office staff helped get my concerns addressed quickly, and the inspector, John Tongol, had great personal interaction skills. The installation crew was very courteous. Brian Thom was also very professional and courteous. Great guy!

I really enjoyed Ohio Basement Authority making corrections from the first install and making it right. This really proved that your company is indeed in tune with customer satisfaction, and it is your No. 1 priority.

The company representative I met with was very professional and informative, evaluating my crawl space and giving his thoughts on what to do.

I was so impressed with Jose Tellez and his counterpart. They called to let me know when to expect them, and they were very professional. They worked non-stop, and the clean-up was great. They even mopped the basement floor. You would never know someone had been working in the crawl space.

I can honestly say I was so impressed from the start to finish with this install and results. I feel it was a value for the cost.
