I wish I had known about Capstone and had gotten their services years ago. We’ve been dealing with water issues in our cemented crawl space for years now. 

My neighbor recommended them and I am very glad I went with them. The fee for their service was reasonable, they were on time and actually finished a day earlier than expected. 

Joe seems knowledgeable and is friendly and professional. They did a great job and we haven’t had any issue with water seeping in since. The crawlspace looks terrific and stays dry.

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.
