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 Nelsonville, OH
Sealing a Nasty Crawl Space in Nelsonville, OH
Maintaining a safe and healthy vacation home away from home for their family is very important to homeowners who frequently say at their log cabin in Nelsonville, OH. After owning the home for about one year, the owners began to notice problems with the dirt crawl space underneath the house. This area was very wet from taking in a lot of water during heavy rains, and it was filled with debris and failing insulation. This concerned the homeowners, and they wanted to address these issues right away. They were eager to contact Ohio Basement Authority after learning more about our company online. After meeting with one of our experienced inspectors, the owners were equally excited for one of our expert crews to transform the nasty crawl space. After removing the debris and other nuisances from the crawl space, we encapsulated the area in CrawlSeal liner. This thick and durable liner completely isolates the crawl space from the earth, acts as a moisture and vapor barrier, and helps insulate the crawl space. Additional installations included the SafeDri sump pump that replaced the portable sump pump the homeowner previously installed, spray foam insulation that was applied to the band joists, and exterior vent covers to further seal the crawl space from outside air and precipitation. The homeowners now have peace of mind knowing these reliable permanent solutions have not only improved the health and appearance of the crawl space, but the health of the home as well.

After living in her house for seven years, a homeowner in Nelsonville, OH, was beginning to notice cracks in one of her foundation walls. She was worried about these cracks getting worse and possibly affecting the safety and resale value of her home.

She knew she could count on Ohio Basement Authority for a permanent solution, and she was eager for one of our reliable repair crews to install several steel I-beams on the cracking foundation wall. These sturdy beams reinforce the wall and prevent further movement.

The homeowner is pleased to have a permanent foundation repair solution that will stabilize her home for many years to come.

Waterproofing a Leaking Basement in Nelsonville, OH
While they have lived in their house for only a few months, homeowners in Nelsonville, OH have already experienced some problems with the home. Water was seeping into the basement and attached garage at the wall-floor joint during heavy storms. This resulted in several areas of puddles that they were constantly cleaning up. Tired of worrying about this every time it rained, the homeowners wanted to fix this problem once and for all. They found information about Ohio Basement Authority online and they were eager to contact us to learn more about how we could help them. They met with one of our inspectors who completed a thorough evaluation of the leaking basement and garage. Our inspector then recommended some of our reliable basement waterproofing solutions. One of our crews then waterproofed the basement and garage with the BasementGutter drainage system and SafeDri Triple sump pump. BasementGutter is placed in the sub-floor to catch any seeping water from the walls and floor. This water is then drained to the SafeDri Triple sump pump. The sump is equipped with three powerful pumps inside a large liner, as well as an external backup battery. Additionally, FreezeGuards were attached to the exterior sump pump discharge line, and YardWell were used to camouflage the ends of the exterior drainage lines in the back yard. The homeowners can rest easier knowing these trustworthy repairs will keep their basement dry for many years to come.

We have a semi finished basement that with heavy rainfall water seeps in where floor and wall meets. Our basement has drywall up and I haven't seen any wet dry wall so not sure if leaking in anywhere else but it for sure does at bottom on floor. And occasionally in odd spots on floor. Has happened in different areas of the basement so not sure if it is fixable without a definitive spot where coming in but there is one area that it does the most. Also a garage under the house does leak as well but more concerned about the living area of the basement right now. Just a little bit stressed every time it is supposed to rain and know it will rain this week and next week according to forecast and ground is already so wet.

The inspector’s presentation was just right. He answered my questions and didn’t oversell or get pushy.

I then chose to work with Ohio Basement Authority because of the company’s professionalism and the belief that I was working with a larger organization that had a great reputation.

Other than the work performed, there was no clue your crew had been there. They worked quickly, professionally, and left no mess. Their use of the plastic wall to control dust was especially appreciated. Martin with the crew also was very nice.

I would call your company first if I ever needed additional services.

Nelsonville Customer Testimonial
John K.
Athens, OH

The company representative I met with was very helpful and professional, and he answered all my questions.

I chose to work with the company because of the thoroughness of the inspection of the issue, the inspector’s explanation of the cause and cure, and why his fix would be better than any other type.

The foundation had a broken corner, due to settling. The work was to raise the foundation of the entire side of the house. The crew was very professional and easy to work with. They stayed to do the job right, even though it took a day longer than expected.

I really liked the thoroughness and the extra time they took to do the job right.

Prior to doing research about basement repair companies, I never paid attention to those types of businesses.

We interacted with two companies, one of which was Ohio Basement Authority. There is a consistency in every interaction with members of your team from the inspector to the service support via telephone, to the installation crew on site.

We chose Ohio Basement Authority because your inspector spoke to us in a cordial manner that established trust and displayed a level of expertise, and because he followed up with us. He was very detailed in his explanation of possible service options.

It was a long drive from Gahanna to Athens each day, but Drew was always clear and accurate with the start time for each of the three days. Each member of the crew was an extension of your staff of inspectors, providing helpful insight about the process along the way. Drew was an excellent leader of his crew and ambassador for your company.

I will certainly keep Ohio Basement Authority in mind if I come across friends or neighbors that need basement repair work.

I was looking on Angie’s List and they contacted me, and I decided to at least talk to them and get an estimate. The inspector’s presentation was very informative and he answered any questions we had. My husband decided to go with them after the presentation.

I chose to work with Ohio Basement Authority because of the knowledge displayed by the representatives and the thorough printed documents left behind to review. I’ve also seen the company’s TV commercials, and we’ve had work done by them at our primary residence in Worthington. They were very helpful and thorough both times.

The office staff was courteous and helpful, and they kept us connected to the appropriate people whether it was getting back to the inspectors or the production staff.

The installation crew was very prompt, and I believe they called in advance to say when they were arriving. All three of them were very nice and friendly, and did whatever they could to please us and do a good job. The clean-up also was excellent.

I heard about Ohio Basement Authority through Angie's List, and I chose to work with your company because of the great reviews I saw online. I also liked the breakdown of the pricing on the products you install so you can see exactly what you are paying for instead of a lump sum cost.

The foreman and the crew were very courteous. He and his crew explained the installation process and went over the job to make sure everything that they had on their paperwork was correct at the beginning before starting the work.

They were always making sure there wasn't any dust getting into my living area. They also answered any questions I may have had about any of their products or the installation process. They went above and beyond everyday cleaning up any work debris.

If I have any more work that I need done in the future, Ohio Basement Authority will be the first one on my list. Also, it is very nice to see such a hard working group of people who seem to enjoy the work that they do, and take pride in the work they do.

I found Ohio Basement Authority on Angie’s List, and I chose to work with the company because of the reviews on that site and the BBB.

Corey did a great job and was very informative. Rich and his crew also did an awesome job! They left my basement cleaner than it was when they started!

There’s no doubt that Corey was part of our decision to work with Ohio Basement Authority. Corey was very professional and knew his product from A to Z. The BBB was also part of our choice, as well as the overall plan as to what was needed and how it would be done.

The crew was great. Each member introduced themselves and shook hands as soon as they arrived. They were friendly, and each knew their job very well. They even were really good with our canine friends who are always in the way.

I chose to work with Ohio Basement Authority because I liked the results and what would be done to fix our problem. The inspector I met with explained the process and warranty to my satisfaction.

The installation crew was very punctual, friendly, and thorough. Thanks, Mike!

I’m a retired Whitehall police chief, having served 37 years primarily in supervision and management, and 16 years as chief.

I learned fairly quickly just how important public relations is. I also learned that people are far more likely to complain about an employee than take the time or put forward the effort to compliment them.

I’ve made it a habit to take the time to compliment exemplary conduct, as well as inferior. I’ve always adhered to the Golden Rule, “Do unto others as you would have them do unto you.”

I can assure you that the inspector I met with embodies the essential characteristics of a model employee/representative. He was punctual and polite, respectful and courteous. He was and is very knowledgeable and informative. He was not pushy. I can’t think of one negative.

I have a high opinion of your company because of my contact with your inspector. I have no doubt he will excel in any assignment he is given. He has much potential.

My compliments for recruiting someone with the potential and demonstrated ability.

Sincerely,

James S.

I’ve seen Ohio Basement Authority’s TV ads, and I chose to work with the company because they had the best price and the best sales presentation.

I waited to respond to any questionnaires to see if heavy rains would cause any basement water to appear. No water!
