Mario was very prompt and personal. He completed the repair and asked us to review his work. We are very pleased with Mario’s performance
Fast and good!
A sump pump was installed very quickly.
Gerry and Davan were excellent. They protected the house and basement from extra dust and just going in and out to get the tools.
Digging up the yard to install the pipe...they replaced the sod and cleared the extra yard waste. Also they were very friendly with our dog.

Gerry, Davan, and Mario came to check the new installed sump pump. Made sure everything was working.
I'd give everyone 10 stars if I could!!!!
Quick response and quick estimate. Enjoyed everything so far.

Work performed was excellent. Jesse was very thorough and did a great job explaining everything during the work
Jesse, Keith, and Trenton did a great job. I'm very proud of the quality of work that they did on both projects and would highly recommend them as your team if you were to have any work done.
the guys came in and very polite and professional and got the job done
Excellent service and work! I’ve worked with KC Waterproofing and Foundation Repair twice now (for foundation work and most recently window well/waterproofing work). I have been satisfied with their work both times. Always easy to schedule and Recently Riley helped with a quote and was not pushy about moving forward; which was my experience a few years ago too. They don’t take up hours of time to give a quote which I appreciate. The team that did the recent work (main contact was Schuyler) were easy to work with and talk too, very kind. You can tell this group of people works together and works together well. They had a lot of hand digging and they did it very quickly. When an unexpected issue arose (removing some sidewalk) Schuyler laid out the what/why/how plainly in an easy to understand way. They did replace the sidewalk concrete. It was a big job and they got it done in a day and a half and were in high spirits throughout. They cleaned up a lot after the project too, which is appreciated. Schuyler did a final walk-through and answered any questions I had. Pricing was good too, I got another quote that was astronomical for pricing and the other company wasted 3 hours of my time to provide a quote. If I need anything in the future I won’t bother with a second quote as I’ve always had excellent experiences with KC Waterproofing. The support staff is very kind and helpful too, as well as prompt. Overall, excellent experiences; highly recommend!
Mario fixed a crack in my foundation. Great work and super nice guy?
