I absolutely loved working with Joe and his team. They did an excellent job on my property. I got a sump pump put into my home after years of having excessive water and flooding. Joe is extremely professional.
Anytime I have any questions I can call Joe and he will answer the phone. My sump pump runs so smooth I can barely even hear it. His team is also very clean and neat. I would definitely recommend them for any waterproofing services that you may need.

From the initial assessment until the work was completed—-to include ensuring my full satisfaction with a final walkthrough, Capstone’s owner and his knowledgeable team were very thorough, detailed and professional.
I’ve already shared his information with my immediate neighbors, family and friends. Thank you, Capstone Waterproofing for a job well done!

Capstone Waterproofing did a stellar job. It was a very challenging situation, but Joe was rigorous and transparent the whole time as we problem-solved and came up with the best and most cost-effective solution.
The quality of the work was excellent. We had to grit our teeth through the DC permitting process, but the job was done as quickly and thoroughly as possible given all the obstacles we faced.
I’m very glad that I could rely on Capstone and that Joe had my back. Thanks!
