Love the business model and service

I had the privilege of working with Jeff Martello when my husband suspected our foundation was shifting. The experience we had with Keystone has been top notch. It was between them and another business when we learned our wall was shearing. Keystone was very helpful in educating us on what was going on, didn't put the usual pressure on us that can be typical of salesmen and even was flexible with our schedule. When they did the work, we had a crazy storm that resulted in loss of power and the road being blocked by a felled tree. I was very impressed with their professionalism and determination to get the job done. Even when they finished, they made sure to bag the trash up. It was very professional. We've had a lot of rain and in the past this meant water coming through, our garage being slightly wet, and mildew. Now, it's much drier and there's only one small spot on the wall that we're working on and I'm expecting will soon be resolved. They're very responsive and very thoughtful about the kind of work they do. I think that the thoroughness of their work, their emphasis on education and willingness to work around crazy obstacles really set them apart from the other place. I would definitely recommend Keystone.

Great service

Recently bought a home and had some issues with warranty. Renae took the time to call me from home and get a person out to me in a timely fashion. Thank you

Excellent service

Renee and Ron have been great through this whole process and made our experience wonderful. They give us confidence to remain working with them for the entire time we own our home!

Homeowner assesment

We had Keystone Basement Systems out to check our basement water back-up due to heavy rains. Scott McGregor came out to evaluate our problem. He was very professional, honorable and courteous. He helped us determine that our original plan was not feasible and suggested that a master plumber was what we needed. This recommendation was outside of Keystone's area of expertise so there was no business for Keystone. Scott was still very willing to discuss our situation. We greatly appreciate this and would recommend Scott and Keystone to others.

Good at 1st

We hired this company twice. The first job they did was ABSOLUTELY perfect. They came on time and completed on schedule. So we hired them for a larger job at another property. This job would pay almost three times the price of the first one. But things have gotten a little hard. We paid our deposit in March and our project was tentatively scheduled for June but we were told no later than July for sure. After several emails asking for a start date (we are in June,)we are now being told our job has been moved to September. Yes, they offered us our deposit back if we wanted to go somewhere else but we really just hoped as repeat customers, spending a lot of money, that we would have been handled a little better. (They do amazing work though)

Waterproofed my basement

I highly recommend this company. They returned my call right away. Started within 3 days of hiring. Came on time. Finished that day. Area was clean and neat when they left.


I selected Keystone for basement work four years ago and then again this year. I interviewed other companies; some were cheaper but not better. Keystone stood out for competence in all regards. They spent a lot of time with me discussing the causes and remedies for my basement water issue. They recommended preliminary exterior steps I should take even though those steps involved using contractors other than themselves. When I eventually did hire them they did a detailed assessment of the project and emailed me three firm quotes with three different options. They give you the specs of their sump pumps, which I compared to other companies' quotes and to recommended specs on internet sites. When I selected an option they provided me with a written contract. They show up when scheduled and the crews are businesslike and efficient, yet gracious in answering questions during the work. When they are done they give you a warrantee in writing. The pumps they installed post email notices to me anytime power goes out (they have battery backups) or they begin or stop working, along with how many gallons of water have been pumped out. Even now if I have a question I just talk them and everyone at every level of the company is what they have always been: customer-oriented, knowledgeable, and patient. I would sum them up by saying they deliver their services the way I wish all residential contractors would: professionally, in writing, competently, and cordially.

2nd Time Around

Ten years ago I had two out of the three basement walls at my home repaired by Keystone. When the remaining wall started to move out of place I did not hesitate to call Keystone to fix. From sales to service you could not go with a better company. I’m extremely satisfied with the work and impressed with how quick and cleanly the job was performed. I’d recommend to anyone.

Excellent service! The job went perfectly!

On May 20, 2019, I had a post installed in my basement. The entire experience was wonderful. From my inspection and quote with Brian, to the completion of the project with Ron, Duane, and Robert, everything was perfect! Special shout out to the guys that did the job- they were AWESOME. Every employee I interacted with was delightful, including scheduling with Anna. Keystone is easy to work with, and their customer service was excellent. I will be recommending your company to my neighbors and friends. Thank you for a job well done!

Exterior french drain installed !

We had an exterior french drain installed in our yard, because of spring water continuously running from a hillside. Josh and his crew, Duane and Robert did an outstanding job. They were all very professional from start to finish. The job went exactly as planned, and all my questions and concerns were answered in a very timely manner. I was really impressed with the cleanup, as I expected to have a messy yard afterwards and that was not the case. I would recommend Keystone to anyone needing this type of french drain installation.
