Honest Evaluation

Brian arrived on time, was friendly and took the time to answer all of my questions. Turns out my concerns were larger than my actual issues and instead of providing me a quote for costly work, provided me a shopping list for some simple DIY fixes. Appreciate the honesty and if I need anything in the future, I will definitely be calling Keystone! Thanks again!!

Dry feet

I live in a townhouse and all of a sudden had a really wet basement! Since it is a townhouse my exterior options are pretty limited . I tried to get hold of several companies looking for help. Keystone was super fast with their response and within minutes had a call back and an appointment scheduled! Scott came to my house and patiently explained the whole process to me, showed me how it would happen AND left me a proposal right their on the table! No question who is going to fix my basement!

Excellent Work

The team from Keystone did a great job and the service was fast and efficient.


I needed a foundation inspection. I called several companies and Keystone was the only one who immediately responded to my needs. Their representative Scott was on time, personable, and extremely knowledgeable. I explained to him that 15 years ago I had another company come in and “waterproof” my basement (Everdry) only to realize that I paid for work that had not been done. So for the last 15 yrs I have had to repeatedly had things repaired. He inspected the basement and educated me on what was done and what should have been done; what Keystone would have done and would have guaranteed. Needless to say I was amazed at how honest and up front Scott was with me. I asked for his suggestions and he did point out a few things that may be addressed, but was honest enough to tell me that since it was another company’s installation they could not guarantee the results. He found no problem with the foundation and offered me a free device which would indicate if something would begin to shift in the future. He put my mind at ease. I would definitely hire this company to do any work in the future. I felt totally secure and confident that they know what they are doing and will completely stand behind their work.


Wish we would have had Josh from the beginning. He was excellent and fixed my wifi . He is a wonderful representative for your company.

Blairsville crew

We had Josh J and crew. Great workers and it was a wicked day as far as heat and humidity. They took great care of the area around the work for which we are grateful. We are very pleased with the job and the clean up was excellent

outstanding service

I would highly recommend this company. Very good work at reasonable prices. Scott McGregor was especially helpful with my unique problem. I would definitely use them again!

Foundation repair

Our experience with Keystone was fantastic. They were professional, quick, clean, and did a great job. Brian came out for the inspection/estimate, and Charles repaired our foundation. Both guys were great. We had another waterproofing/foundation repair company at our home several years ago, and we were not impressed. We highly recommend Keystone.

Internal basement system

Josh J and crew came out did an excellent job. They were in and out job done in 8 hours. Very pleased with the work and system that was installed. They left my basement clean ,and just the way it was when they came. I used keystone in my old home. I just purchased a new home, and used them again in this house. Customer satisfaction is diffently pleased. Thank you kestone.

Good Job!

Josh and Robert did a great job installing a sump pump in the basement entrance under my Bilco doors. The concrete was incredibly thick and difficult to remove. Ron was great on the ditch witch with minimal landscape damage. Would hire again any time.
