The first owners of our house had the basement waterproofed by Ohio State Waterproofing. The previous owners did not work with Ohio State Waterproofing, but the company was still willing to transfer the warranty to us when we moved in. Since then we had a small drip in the basement near the sump pump. The tech who came to investigate had a hunch and fixed it right then without needing to schedule a crew. I really appreciated that, he went above and beyond.

When we bought our house over 17 years ago, the basement had already been waterproofed by Ohio State Waterproofing. We were able to transfer the warranty seamlessly, and have never had any water issues in our basement! We pay a modest yearly fee to continue the warranty. Any time I've had to contact Ohio State Waterproofing with any questions I have always had very friendly and professional people to talk to. Thank you!

We had Ohio State Waterproofing come out to our home at the beginning of April to do a complete waterproofing of our basement. The process from the beginning to the end was very smooth and we are definitely happy to have our basement safe from water damage. The crew who did the work was very professional and knowledgeable, especially the foreman Carlos.

He answered any and all questions I had and walked me through each step of the process. We are also very happy with the follow up care we've received ensuring everything they did was up to our liking.

We used Ohio State Waterproofing about 11 years ago. This high quality service is excellent. They came out on time, we're very knowledgeable and professional, and friendly. They solved the water problem coming through the walls and into our basement. I don't have to worry anymore when it rains hard because our basement doesn't flood anymore either. To top it off, they have a lifetime warranty! I would highly recommend this company.

My basement was waterproofed by Ohio State Waterproofing when I bought it 20 years ago. I was allowed to transfer the warranty that the previous owner had on the waterproofing. I did need some additional work done and they were eager to correct the issue I had. The men who did the work were polite and friendly. They worked hard and they cleaned up the work area when they were finished.

They did a great job inside my basement. Basement waterproofing is an important step for a homeowner to take to protect their home. Call this company! They will do a great job!

I first spoke with Paul at their office about getting an estimate and they were very flexible in scheduling. Lee just came out this afternoon to inspect my basement. Very professional and knowledgeable. After the inspection he sat down with my wife and I to explain everything. Lee was very thorough in explaining what the causes were and our options for repair. I think I made a smart choice going with Ohio State Waterproofing. I already have peace of mind knowing my basement will be dry.

Shortly after purchasing our home, in 2003, my husband and I contacted Ohio State Waterproofing. We had our entire basement waterproofed and we have no regrets. The company delivered professional workmanship and quality materials. The team arrived on schedule, they were courteous and professional. To my surprise, they did an excellent clean up, upon completion. We highly recommend this company.

We had Ohio State Waterproofing waterproof our home a few years ago and the overall experience was great. The salesman was very professional and explained the whole process. The crew was prompt and worked hard. Waterproofing is a very dirty job. They covered everything they could and cleaned up very well afterward. It snowed while they were performing the job but they didn't miss a beat. I have not needed any follow up service. The walls are dry enough that we were actually able to paint them with no issues! The transferable warranty is a plus.

We had Ohio State Waterproofing waterproof our basement. We had many appointments with companies to do this project. OSW was our last appointment and by far the best appointment we had. Their prices were unbeatable and the transferrable warranty was a huge seller. In the 20+ years since they did the project they have only had to come back out 2 times to replace a part in the sump pump. Never at a cost to us and both times the service person was top notch! Thank you for being such an amazing company to work with!

We had water in our basement. The technicians came out the same day to give us an estimate. They were professional, prompt, honest, and we were prepared for a large job along with the price. They took the time to assess every area and let us know that there was a simple fix we could do ourselves, saving us thousands of dollars. I would recommend them to anyone - Thank you Ben!

I had another waterproofing company with a forever warranty waterproof half my home many years ago. I could not afford to do the complete home. The only problem was that they went out of business a few years later, and my basement needed attention. Called Ohio State, got a very reasonable quote for the entire house. I had the work done in 2007. I recently needed some touch up work. A team came out and completed the work in no time. Very happy.

I bought a home that had been waterproofed by Ohio State Waterproofing. I have continued the warranty as the new homeowner. Their product has performed well so far, and they have been responsive and thorough during my interactions with them Service: Waterproofing

13 years ago, Ohio State Waterproofing came to my home and FIXED the water issues in the basement that I had experienced for over 8 years. Also installed the EZ-Breathe air system. Their work was exceptional (completed on-time, cleanup, covered items in basement & flowerbeds for protection). The professionalism from their office personnel and work crew was very impressive.

I chose Ohio State Waterproofing after comparing others in the same market as well as from existing customers. The annual low-cost warranty gives peace of mind and is transferable. One does not find that combination in too many places today. HIGHLY, HIGHLY recommend this company!

The basement was waterproofed in 1984, and we moved in to the house in 1990, continuing to pay the yearly warranty. We have had work done to an outside corner and are so happy with the quality of work and terrific service. Also, had a new sump installed under warranty. All workers are knowledgeable and professional. Service: Waterproofing

I would like to compliment Ohio State Waterproofing for this excellent value for thier service. We have enjoyed a dry basement for many years in our home. Several years ago we had a small problem. I called them and they followed up and it was quickly fixed. Service: Waterproofing

Several years ago, my husband and I had water in our basement and Ohio State Waterproofing was recommended by a family member. We could not be happier with our decision to go with the company. They were on time, informative and respectful of our time and space. The yearly fee to continue coverage is well worth the peace of mind we are provided. We highly recommend this company to anyone looking for waterproofing!

11 years ago our basement was waterproofed. They have a cheap warranty plan that is worth keeping active for any unforeseen problems. We only had to call when the sump pump stopped working. They were out right away to replace the pump. It's nice knowing this company truly stands behind their work and customers needs. Service: Waterproofing
