French drain and sump pump system.

Product and service are great. Thanks.

Great experience from start to finish

I'm so glad I chose Keystone Basement Systems to do my interior French drains and exterior surface trench. I had 3 different estimates and Keystone was in the middle price wise. Here are 3 reasons I chose Keystone: 1. Jeff the salesman was very informative, wasn't pushy and didn't try to upsell any other products/services. He said the products sell themselves and he was right. 2. Keystone was able to do interior and exterior work 3. The Pump Spy app for smartphones. It tells you if your sump pump is working properly, alarms you if the backup battery clicks on, shows total pump cycles, gallons pumped etc. The crew that did the actual work was great too. They were on time, worked hard and were very professional. I wasn't able to take off work when they were at my house. After meeting them the first day, I felt fine leaving them alone at my house while I was at work.

Great Work

Completely satisfied - workers arrived on schedule - did a great job - cleaned up dust and debris at end of work. I haven't had any water problem in basement since they finished the project . Fully satisfied and recommend them.

Highly Recommend

We had a great experience with Keystone and will use them for all of our future waterproofing needs. I met with Brian at one of our rentals and he was very thorough in explaining the process. The crew showed up as scheduled and finished early. I received several quotes prior to deciding on Keystone. They were not the cheapest proposal but their level of professionalism left me confident in my decision to choose them and I’m pleased with the results.

Accurate pricing, no overselling, great results

I am a geologist who studied hydrology so I had have a good idea how hydrostatic pressure and whatnot works. Found I had a small leak in my basement which a wall is against a hill entirely so I shopped around for basement work. A couple other companies tried to sell me an entire circumference inner and outer French drain for more than 16k. These guys came in and gave me their evaluation to just 52 feet inteiror drain as all I would need given both the precipitation in my area and location (I live at the top of a hill) along with how my property slopes... when I told them I was quoted by two other companies for an entire inner and outer drain, they did offer it to me with the cavat I would be doing overkill. Can't say many companies don't try to get you to spend more! Needless to say, I went with these guys. Their assessment was similar to mine and a personal engineering friend's and they did not try to oversell me with aluminum siding on brick walls!

Above and beyond

We hired Keystone Basement Systems to install an internal French drain in our basement that ran along the perimeter of three walls (68 lineal feet total). The work included the French drain, installation of a sump pump system, and finishing work: replacing framing and insulation, rewiring, new dry wall with taping/finishing, painting, etc. Overall, we were very pleased with the quality and performance of Keystone’s work. Installation of the French drain was completed quickly, in a professional and timely manner; and their team of workers were dependable, professional, highly skilled, and hardworking. Their attention to detail, and not cutting corners, was specifically noted and appreciated. From start to finish, Keystone’s business practices were exemplary. It was a pleasure dealing with all of Keystone’s representatives who were involved in the job – including Keystone’s job inspector, estimator, designer, and lead carpenter. Keystone should take great pride in its employees and each one’s level of competence!
