Great Customer Service

Barry arrived to do a 5 year inspection on my Sump Pump and Battery Backup. The inspection went well, everything working as expected. Thank you Barry ! Also a big thank you to Renee, what a pleasant and personable lady 😀

True professionals!

Brian was just out to inspect our basement. We were pleased to learn that our basement is in solid shape and we don’t need any significant work. A true professional and they did not try to sell us something we don’t need! Highly recommend this company.


We were very pleased with his professionalism and knowledge regarding our situation with our foundation. He was thorough and explained our options clearly. We appreciate his estimate and his time.

Top notch company and service

I called with a basement water issue at my mom’s house and Jeff Martello came out. He was extremely knowledgeable and explained everything very thoroughly, my 92 year old mom felt so comfortable. She decided right then, this was the company she wanted to correct her issue. The installers were very competent and neat. My mom was impressed with their work. She has not gotten any water in since their work was completed. She doesn’t even have to use her dehumidifier any longer. This company is highly recommended.

Good guy

Friendly and professional

Keystone assessment of basement issues

Brian was friendly, courteous and informative. He answered all questions asked thoroughly.

Highly satisfied

Basement was in deplorable condition. Tony came with his crew and with a minimal amount of dust did an excellent it has been five years and we have never has a drop of water. Keystone also came in to do a five year inspection and clued the french drains to ensure there was no obstruction and working properly. I highly recommend keystone for their expertise in doing the job and for their excellent customer service.

Refreshing professionalism

Brian McWhirter came to our home for an estimate. He put us at ease that our floor problem wasn’t due to the foundation but sagging joists. He advised me to pull down an area of the garage ceiling so we could better see the problem. Then he could return to give us a more detailed estimate. So refreshing to find a contractor who is honest and goes the extra mile. Thanks, Brian for your professionalism!

Brian is professional and honest!

Brian McWhirter came to our home for an estimate regarding our sloping floor and wall crack. We were afraid that it was a very expensive foundation issue but Brian explained that it was actually a structural problem with the joists that will cost far less to repair. Thank you Brian for your knowledge and honesty!


Very nice and kind service today. Answered all my questions and concerns.
