Estimating job

Tony Delprete was sent to look at our job and submit an estimate. He was very polite and professional. He took the time to explain exactly what he saw and how to remedy the situation. We have accepted his bid and are looking forward to working with the company.

Very Satisfied

Jeff came out in response to my call. He took time to explain everything to me and answer all my questions. He didn’t think I needed any work done presently, but if any changes develop I wouldn’t hesitate to call again.

So far so good

I had an inside French drain installed in my basement after being flooded a few times in the 28 years I have lived in my home. Jeff who gave me my estimate was very professional and kind. It did take a while to get it scheduled, but understandable considering all the flooding in our area. The foreman on the job, Tony, was also very professional and knowledgeable. They were able to finish the job in two days and did a good job. I can't comment on the actual system because it has not had to come on yet.

Great Service 18 Months In

Keystone Basement Systems installed an interior french drain and sump pump at my house in 2018. In an exceptional show of tenacity the crew was able to do the work while huge volumes of water continued to enter the foundation. It was only after the work was done that we learned this was due to mine subsidence. Because of the mine subsidence our pump is active 24/7. Despite this heavier than normal workload the basement stayed dry and the pump is working well. We had one issue recently where the float needed replaced. Renee was extremely helpful and added us to the service schedule same day. Chuck did great work and we were back in business without issue. A huge thanks to the whole KBS team for their great service over the past year and a half!

Field Inspector

Scott arrived on time and is very knowledgeable about waterproofing and repair. He gave me different options to choose and no rush or high pressure. I will highly recommend him to others!!


Scott was ver nice to work with. They finished the job in one day!! They explained what they were going to do and answered any questions that I had. Great company to work with.

Michael Garber

I had an appointment with Michael Garner yesterday 9/16/19 and all I can say is he gave me a lot of great information about my basement situation. I really appreciate all that he and his company has done for us to help us find a financial resolution to help us get our basement in tip too shape. He even gave me advice on other questions I had that didn't pertain to what he was here for. Thank you Michael and The Keystone Basement Co. For doing all you can for your customers.

Initial Visit

Mike Garner was super professional and very knowledgeable. He listened to our needs and was able to help us with our water issue. Thanks Mike.


The number one complaint about contractors is the customer not getting what they thought they were… There was a difference in expectations…
