"We wanted to finish part of our basement but had concerns about a few areas where there were leaks during long sustained or heavy rains. We knew the risk of mold and other unknown damage behind finished walls was too high of a risk for our investment and health safety. We did research of basement waterproofing companies in the Cincinnati area and settled on Everdry after determining they had the best reputation and track record based on review we read. The job was way bigger than we ever anticipated, but the workers were careful and considerate of our space inside and outside the house, and they returned everything to as normal as could be considering the level or work required when they were done. There were a few times over the first few years when we needed Everdry to come back to repairs some chimney leak issues in one of the unfinished areas of our basement, but they were efficient and persistent in resolving the issue. 15 years later, we are still enjoying a dry and comfortable finished basement. We are very satisfied customers."

"Will H and his team Corey B and Christian H, were polite professional redo my waterproofing my basement and, putting in a new sump pump. Will walk me through the whole process step by step if you had questions or if he had questions they were answered immediately the process was very smooth due to Will's knowledge and professionalism. What was thought to be a two-day job and ended up being a one-day job. I would hire Ohio basement authority if I again if I had any more problems and I'd certainly recommend them to anyone who does have a problem."

"Overall, we had a great experience. The waterproofing job was great and works perfectly. The only downsides to our job were: 1) they were suppose to seal off the things in our basement so they didn't get dusty - the seal job wasn't good though so we are still cleaning everything off as we have time weeks later. 2) they were supposed to cosmetically fix some cracks, but it looks sloppy. They just took a caulk gun to it... In our consultation, they had mentioned they would do this pretty, smooth coating thing, which was not done. 3) they did not clean up well. Our floors had dirt all over them when they left and I had to sweep/mop myself. While the above things were annoying, the important parts of the job (the actual waterproofing) were great and look and work perfectly. So I would still give them an A."

"ErieHome waterproofed my basement. The crew was polite, kind, and came in, did an excellent job in 3 days by digging a trench on the inside of the basement, removing the dirt from the bottom of the foundation, installed corrugated tubing, rock and then cement. They also installed a Humidex airpurifier and new sump pump with a backup pump. They cleaned up afterward. Any questions I had were answered in a respectful manor. I now have peace of mind knowing that I no longer have to monitor weather forecasts for rain or have to clean up anymore incoming water. The system is warranted for the life of the house and included within the price, which increased the value of my home."

"I felt like Bluegrass was the most honest in regards to the actual work that needed to be completed. I was quickly able to get on the calendar for the foundation repairs that were needed on my home. I was very impressed with the team and the quality of their work. I highly recommend them!"

"I dealt with Tim for the price and project details and then Jeff was the man who came out to do the job. The deck had previously been done by a guy who did not know what he was doing so Jeff power washed the entire deck and let it dry for 24 hours, then he sanded the deck and scrubbed it down with denatured alcohol to help remove any remaining paint from before. When the deck was dry, Jeff taped off everything and proceeded to edge everything before he rolled a nice thick layer of paint on the deck. We waited another 24 hours and Jeff returned to apply a nice second coat of paint on the entire deck. Tim and Jeff are very easy to work with and I will most certainly come back to them for future projects."

Me and my wife had recently purchased our home. Shortly after we discovered there was water damage in the basement we didn't know how serious it was until Brian (One of the owners of Basement Armor) came out to inspect. He found the home had concrete steps, which were covered by a wooden deck, and the steps began to sink and created a void to which water was filling our crawl space and eventually making its way into our basement.  (Previous contractors didn't even mention the steps)

The first good thing about Brian and Basement Armor is the price was very affordable for the amount of work he did! We had two other companies come out and the prices they quoted us was unbelievable and their work did not include the French drain in the basement. Brian offered me references and I was able to contact them and even view the work he performed. Everyone I spoke to had nothing but nice things to say and viewing the work he performed had me sold.

The next thing that really stood out was Brian, the owner, was actually in my basement performing the work WITH his guys! This I have never seen. This made me feel at ease about the work being performed, he was approachable and kept me and my wife in the loop about everything going on. Brian made sure the work being performed was to his satisfaction. He even took care of a few things that was not in the contract.

There are so many good things I can say about the work performed by Basement armor. Its the little things that count and Brian takes pride in those little things. While disconnecting my washer and dryer he noticed we had a leak from the kitchen down into the basement. He took care of it for us without charging extra! Other companies would have not even acknowledged there was a leak, let alone fix it with no additional charge. I hope I am making it clear Brian did an outstanding job for us! We are on his list of references and we highly recommend Basement Armor!

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in California, KY

Yes, crawl space encapsulation is a good investment. It improves your home's energy efficiency and air quality, boosting its value. With routine inspections and maintenance, encapsulation provides a long-lasting solution to moisture and pest issues. Regular check-ups protect your investment, enhance energy efficiency, and maintain your home's structural integrity. If your home is prone to pests or moisture seepage, encapsulating your crawl space is definitely worth it.

A vapor barrier is a thin sheet of plastic that prevents moisture from seeping into your crawl space, while insulation prevents unconditioned air from entering. Combining both insulation and a vapor barrier creates a dry, temperature-stable environment. Some insulation products serve both purposes, enhancing energy efficiency and protecting against moisture and temperature fluctuations.
