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.

Sump pump installation

Timely, good communication, basement walls still get mold/mildew despite internal drain and pump and dehumidifier ran 24 hours a day. So not sure if worth it.

Awesome service

Keystone Basement Systems installed carbon fiber straps for me twice now - 2 difference residences. Their expertise and great work mitigated some movement issues in my basement walls. They are phenomenal- from pricing the job to completion, they were professional, detail oriented, and meticulous. I will most definitely hire them if/when I have future needs. They are a fantastic company to work with.

Excellent work

We had a sump pump installed. I am very pleased with the work that we received. I was told would take 2 days to complete and was very surprised coming home from work at 2pm the they were finishing and cleaning up. Job was finished. There was little mess and they dis a great job cleaning up. Pump is running great!!! Would definately refer my friends and family.


The crew was very professional and cleaned up after the job was completed. I would recommend Keystone Basement Systems.

Peace of Mind

I am very satisfied with the work Keystome Basement Systems did. I no longer have to be home every time it rains, the expanded drains and the pump keep our home dry. I call this peace of mind!

Water problem solved.

About 50 feet of interior drain was installed in one day with relatively little mess. Despite all the rain last year, no water damage to the finished basement.
