Great Service

The whole process was wonderful. I am not very good with computers and was having issues with my WiFi. I called my inspector, Jeff M, and he walked me through a couple things. It was honestly all above my head so he offered to come by and correct the issue for me. It is service like this you don’t get any more these days. Highly recommend Keystone Basement Systems and Jeff.

Good Job

Crew arrived on time and ready to work. All interactions were respectful and businesslike. They cleaned up and took away all waste and excess materials. End result is bone dry after full day of rain. 100% satisfied. I would call them again.

Terrific job.

The guys from Keystone Basement did an excellent job in extending my waterproofing into the basement den. With the water table close to my foundation I needed two pumps to keep up with the water when it storms.

Great work

The team was awesome! Dylan and Dewy were top notch and answered all of my questions! They did amazing work. I had a big job for them and they came through for me! The team was professional and courteous. I had stains put in, I beams in for a bowed wall, cement work done and took out a huge slab of concrete that was making the wall now in! Great job guys!




I had work done last year and wanted to do some additional work. Dylan Stewart explained what needed to be done to complete project. He was courteous and knowledgeable. Work is scheduled to be done in January. No more water worries.

Fantastic Honest Service -- Twenty Stars!

Had periodic water in basement in basement corners and against walls. Scott McGregor came out and inspected the basement and then inspected the outside of the house. Scott determined my problem could probably be fixed or at least minimized by putting an extension on my downspouts and if this worked I could put an exterior French drain that would run from the downspout to the yard. Other companies wanted to install a vapor barrier, interior French drain nd sump pump in the basement. I had estimates from four other companies that ranged from $9,000 to $23,000. It is rare to find an honest company that works with you to save you money. Obviously I highly recommend Keystone and they will be the first call I make for any services they provide. Highly recommend! Thank you Keystone Basement!

Downspout and Rain Conductor System

Upon discovering substantial dampness and mold behind our wainscoting in our finished basement, we called Keystone to come take a look. Jeff was very friendly and professional, and spent a great deal of time with us explaining our options and how everything would work. As it turned out, our project was a moving target and Jeff ended up coming out a few more times to talk to us about it and was very patient with the process. After we settled on what we actually wanted done we got scheduled pretty quickly. When the work started, I found Chuck to be very courteous and took the time to explain the work that he was doing as he went. All-in-all, I’m very happy with the work that was done. Now just have to wait for the next big rain fall to see how it goes. I would definitely recommend KBS.

Great job

Jeff originally came out to give me an estimate. He was very professional and on time. It took a little while for the job to start due to all the rain we experienced in our area. The foreman on the job, Tony, was very professional and kept me posted on what they were doing. They were able to complete the job in two days. The crew cleaned up and did a nice job. I can't comment on how the system works because it hasn't had to work yet.
