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!

Interior and Exterior Waterproofing Solutions Create a Dry Home for New Homeowners in Caledonia, OH
After moving into their house in Caledonia, OH, new homeowners noticed water intrusion in the basement. They wanted to address this issue as soon as possible so their home will always be dry. The owners contacted Ohio Basement Authority after learning more about our company online, and we installed various reliable waterproofing products products. These included the BasementGutter interior drainage system. We replaced the older sump pump with the trustworthy SafeDri Triple sump pump system, which will always work to keep water out of the basement. We also updated the exterior drainage line, installed a YardWell outlet to camouflage the end of the buried pipe, and attached FreezeGuards to the exterior sump pump discharge lines. The homeowners were excited to have these permanent solutions installed so their longtime home will be a safe and dry living environment for many more years to come.
Permanent Waterproofing Solutions Will Always Keep an Older Home Dry in Caledonia, OH
While completing various construction projects in an old home in Caledonia, OH, a local restoration company noticed evidence of water intrusion in the basement. This company worked with Ohio Basement Authority on several other projects, so the contractors felt confident in contacting us to provide the best solutions. To address the issue of seeping water, we installed some of our many reliable basement waterproofing products. These included the BasementGutter interior drainage system and SafeDri sump pump, which will always work to keep the basement dry. Exterior products were also installed including an FreezeGuard that was attached to the sump pump discharge line, and a YardWell outlet that camouflages the end of the buried line. The 115-year-old home’s stone foundation walls were sturdy, but still concerning because of the seeping water. CrawlSeal liner normally used in crawl spaces was used to cover the walls. Not only does this durable liner help direct water from the walls down to the BasementGutter system, it instantly brightens the basement and improves its appearance. The home will now be a safe, healthy, and dry living environment for many years to come. Permanent Waterproofing Solutions Will Always Keep an Older Home Dry in Caledonia, OH - Photo 2
BasementGutter and SafeDri Super Sump Installations Correct a Leaking Basement in Caledonia, OH
Homeowners in Caledonia, OH, have lived in their home since it was built 45 years ago. For the last 10 of those 45 years, the owners have noticed water seeping into the basement and puddling on the floor during periods of rain. The owners were tired of dealing with this constant issue in their finished basement, and were ready to address it once and for all. They received estimates from various repair companies, but felt more confident in Ohio Basement Authority’s solutions. We installed the sub-floor BasementGutter interior drainage system, which intercepts any water that may seep into the basement. This water is then directed to the SafeDri Super sump pump that was installed to pump the water out of and away from the home. A FreezeGuard was attached to the exterior sump pump discharge line to prevent flooding from frozen or blocked pipes. A YardWell outlet also was added to camouflage the end of the buried portion of the discharge line. The owners are pleased to have a reliable basement waterproofing system that will keep their home dry for many more years to come.
Waterproofing a Leaking Basement in Caledonia, OH
Upon moving into his house, a new homeowner in Caledonia, OH, noticed a glaring problem in the basement. Water was leaking inside through the walls and floor, leaving visible damage behind. The owner wanted to have this problem fixed right away, so he turned to the Internet for research. After finding information about Ohio Basement Authority, the owner was eager to contact us to learn more about how we could help him. He met with one of our inspectors who evaluated the condition of the leaking basement. Our inspector then recommended some of our reliable basement waterproofing solutions. One of our crews then waterproofed the basement with the BasementGutter drainage system, a SafeDri Triple sump pump, and CrawlSeal wall system. BasementGutter is specially designed to sit in the sub-floor and atop the footing to catch seeping water from the walls and floor. A section of grated grated drainage was placed in the floor in front of the walk-out access point and connected to the BasementGutter system. Any water intercepted by the BasementGutter is then directed to drain into the SafeDri Triple sump pump system. The SafeDri Triple features three powerful pumps inside its liner, as well as an external backup battery. The CrawlSeal wall system also was used to help seeping water from the walls flow behind the liner and down into the BasementGutter system. The new homeowner now has peace of mind knowing these trustworthy repairs have helped him create a safe, healthy and dry living environment that he will be able to enjoy for many years to come.
Mitigating Elevated Radon Levels for a Healthier Home in Caledonia, OH
As they moved into their house, new homeowners in Caledonia, OH, wanted to ensure the health and safety of their living environment. This included addressing potential radon in the home. Radon is a naturally occurring radioactive gas that is produced by the decay of uranium in rocks and soil. It is found in homes across the globe. While it cannot be seen, smelled or tasted, its effects are very real. Radon is the second leading cause of lung cancer, and prolonged exposure to this gas also has been linked to more than 20,000 annual deaths. These factors greatly concerned the homeowners, so they started to research how to best address the issue. They contacted Ohio Basement Authority after learning about our company through online resources like Home Advisor. They met with one of our inspectors who helped them administer a test to gauge the level of radon in the house. They were surprised to learn the test results indicated the home’s level was 34 picocuries per liter (pCi/L). This is more than eight times higher than the level at which the Environmental Protection Agency recommends mitigating radon. The owners were then eager for one of our crews to install a radon mitigation system. This involved drilling a hole into the basement’s concrete floor to create a suction point to draw radon from the home. Thick ventilation pipe was connected to this hole and directed up into the attic where it connected to a ventilation fan. More pipe was extended through the roof for safe and effective radon expulsion. The existing sump pump pits also were utilized as suction points, and domed and sealed lids were placed on the pits to prevent radon intrusion. The homeowners are happy this reliable repair was completed to help them create a safer and healthier forever home.

I chose to work with Ohio Basement Authority because of the company’s ratings and the cost of repairs.

The inspector I met with was very thorough in his presentation, and he described exactly the procedure used and the expected results.

The crew answered all my questions and proceeded with the installation without delay. The three-man team had the installation down to a science. Each took a portion of the job and proceeded seamlessly in their work to work very efficiently.

I've heard about Ohio Basement Authority through TV commercials and yard signs, and I chose to work with the company because of very good online reviews and the professionalism of the staff.

My inspector was very friendly and made sure I understood everything he explained regarding my problem and the solution. The crew did a very nice job. They were both very courteous and friendly. I was very appreciative of the extra time they took to protect my home during the installation. There was absolutely no mess left behind at all. Top-notch technicians!

We saw Ohio Basement Authority's television ad. We were so excited that the day we called to schedule an appointment there had been another customer that had to reschedule. We were able to take that appointment and our basement was completed that week!
 
OBA did not try to sell us on having more work done than was necessary, but told us what was recommended at a minimum as well as other options we could add if we wanted. Dave was extremely respectful, thorough and informative. 
 
Ben and Eric with the crew were great! They were very respectful and friendly. Everything was cleaned up and looked just like it did before they started.

I first heard of Ohio Basement Authority from the Spring Home and Garden Show 2014. Then I read two of Lawrence Janesky's books, "Dry Basement Science," and "Crawl Space Science."

Your office staff was very professional, and the representative was very thorough in evaluating the needs of my home. His experience and knowledge game me confidence to trust his judgement and staff in completing the job.

The books and photos written by the CEO were very helpful for me. My son-in-law watches "This Old House," Bob Vila, and TV shows that feature the best research info. James verified and recommended these procedures, so my decision was easy...Ohio Basement Authority.

The crews worked constantly and together as a team. They obviously have an excellent work ethic and want to provide the best job possible. They were absolutely courteous and helpful in every way. In fact, I had a huge branch fall overnight, and they offered to cut and dispose of it. The house was cleaned up daily with very minimal dust and no extra work on my part.

Justin was the foreman, and he kept me posted on the work completed daily by the crew. He explained work clearly, asked if there were any questions I might have, and responded thoroughly.

I will be recommending OBA to anyone interested.

I heard about Ohio Basement Authority on a TV commercial, and I chose to work with the company because of the customer service and the pricing.

The office staff was very accommodating, and Matt, the inspector I met with, was great. He was very informative, yet no pressure to buy anything. The installation crew arrived on time and cleaned everything up well. The crew members were very good at their jobs. They answered every question I had, and they were persistent in their efforts to get the job done right despite a couple of hiccups.

The representative was awesome! We were so overwhelmed, but not once did he put pressure on us and was ALWAYS there to answer our many questions. The experience was great from the very first phone call. Questions were always answered and no sale pressure.

The crew was awesome. Our foreman was the best! We saw him treat his crew with respect. The entire crew was respectful to one another. I never expected it to be so clean after a project of this size. We are VERY pleased!

We would highly recommend your company to anyone with basement needs. We were amazed at what they did for us and how smoothly it went. We were very comfortable with the entire process.

The representative you sent out was very thorough and had an obvious interest and concern in listening to and meeting our specific needs.

We chose Ohio Basement Authority because you were prompt to return calls and followed up with us. You also generally seemed more interested in the job than other companies.

The crew led by Jose was fantastic! They went above and beyond our expectations. When the water-damaged basement steps started to come apart after pulling them away from the wall, Jose took it upon himself to attach replacement stringers and replace the bottom two steps that were unsafe to use. That's incredible!

The clean-up was also exceptional! They left it cleaner than when they arrived!

The office staff has been fantastic with complete follow up and excellent communication. All of the reps that I have dealt with were excellent, professional, courteous and personable. The crew was professional and polite. I requested they call me on my cell phone prior to coming so that I could meet them at the house, and they did. I have worked with other contractors and requested the same thing, and it never happened. So I was very pleased with the follow-up.

My inspector did a great job. He was knowledgeable and responsive. His professionalism and the fact that your own employees would be doing the work made me choose Ohio Basement Authority.

The foreman and the two guys he had with him were excellent. They installed a drainage system around the whole house for all of the seven downspouts, sump pump and three window wells. We had a very good experience and they did what it took to do the job correctly. We would recommend them.

The company representative I met with was friendly and professional. Another company seemed like a hard sell, and one other was expensive and I didn’t like their solution as well.

The installation crew was very careful. They put down a plastic runner where they would be walking. They had to dig a ditch in the lawn, but didn’t disturb the lawn or plants surrounding the ditch.

They cleaned up the water in the basement from a previous storm and sump pump failure, and they were very friendly.
