The French Connection

Having used Keystone previously for another job, I was hoping that I would have a similar satisfying experience. I am pleased to say that Keystone delivered once again. From the time I scheduled an inspection and estimate I was pleased. Kelly came and provided me a very detailed explanation of the work that needed to be done. The crew that completed the job: Juan, Shawn, Austin, and Scott were punctual, friendly, professional, and thorough! These guys were amazing and completed the job in no time. I am totally satisfied…just waiting for a nice rain storm to see the French drain that they installed do its job!

Troubleshooting sump pump

Technician was professional, knowledgeable and courteous. He had the issue diagnosed and remedied with 10 minutes. We are very happy with the outcome.


Brian was very nice and easy to talk to. He explained the whole process from beginning to end. Also, he answered all of my questions. I feel confident that I selected the right company.

Quick and clean.

The two man crew that hooked my basement up were early on the job and clean with wrapping it up at the end. Very good experience and my basement is dry as a snare drum. Thanks!

Warranty repair

I’ve had several jobs done by keystone and happy with them all .. this is the first time I’ve had to deal with them on a warranty repair .. To me this is the real test of a company cause anymore no one stands behind their warranty anymore. It’s something that makes me crazy angry when dealing with a company that promises the world and doesn't . In this case keystone did indeed stand behind their warranty no questions asked.. it wasn’t seamless, it took some back and forth over 3 days but in the end they sent a guy out and they swapped out the failed pump no questions no charges .. Thats how warranty repair should be handled .. Not this crap I see from HVAC companies and such where they then tell you parts are covered but labor is still charged and they charge you such high rates you basically just paid for the warranty parts too - lol Keystone came out and replaced the entire pump , put a brand new one in and no charge for anything !! Yes how warranties should be !!! Thanks Renee, Barry, and Brian

Cracked concrete/pump float

Barry did a great job fixing the crack and replacing the float. Highly recommended.


I received an estimate from Brian today for my foundation and internal french drains. He was professional, personable, and very informative. He explained everything in complete detail making my decision to book with Keystone Basement Systems easy. They have lots of financing options and the process was quick and smooth. I'm looking forward to them fixing up my basement!


The number one complaint about contractors is the customer not getting what they thought they were… There was a difference in expectations…
