Took care of our water problem. Alleviated a lot of stress and saved our finished basement.

Like a previous customer noted Rick does the sales and Wendell and team so the work. Rick has zero knowledge. And the work was sloppy, unprofessional and Wendell only came back to look at the work since I complained. After being told he would fix it, he never did. He also said he would return material that his people told me to order - and was incorrect - and never gave me the money back. Dishonest, poor quality. Dont use them

A+!!!! Stephen was at my home same morning I contacted him and scheduled the work right away. His partner Wendell and his crew arrived on time, was very efficient, installed the sump pump system, and added a drain below the bulkhead stairs. I’m super happy with their work, they did it in 1 day and cleaned up the area very nicely. The system was installed as described and with high quality. I highly recommend Key Waterproofing if you need to address water in your basement.

Later Edit: The company followed up with me and ultimately came back out to address the issue. It's not a perfect repair, but it does allow me to connect my dehumidifier, which was my main priority in asking them to return. I have been trying to resolve a problem for 6 months regarding part of the job that the workmen had mishandled. It was a minor, quick fix, but once I paid, they were gone for good. There were also some questionable communication practices, where the workmen would question a piece of the contract and try to negotiate a better solution than had been proposed for cash on top of the contract amount.

Very satisfied with our experience - they came in and were able to fix our water issue to get our construction back on track within a week of my first call and provided a comprehensive multifaceted solution. Very impressed and would hire them again no question. Highly recommended.

Always prompt: both for the quote and the work. Very clean. Knowledgeable and offered clear explanation. I can't give 5 stars for the work quality because it hasn't rained yet. Very good price point for this work.

The workers installed a vapor recovery system in a crawl space that was heavily littered with deteriorating plastic and debris from twenty years of neglect(old insulation ,plumbing debris etc.). They cleaned out the space and installed a beautiful new system. The workers were focused , hardworking, and pleasant. I recommend this company whole heartedly.

It took many calls to get the team out to bury the exhaust pipe for the water. They were hampered by COVID staffing issues, but other than that the crew was great, and the work was well done. I did look when we had rain after the work and I saw no water in the basement.

Wendel's team worked extremely efficiently to complete my full perimeter interior french drain and sump pump installation after a previous contractor stopped showing up for the work. They were done in a day when the previous project was taking months.

Wendel and his very hard working team did an excellent job and I will submit another review after our next significant rain event. I was especially impressed with team 1 lead by Emanuel and the great clean up they did as well. They finished in a day and a half versus 2 day estimate. Drywall phase completed in a timely manner as well. The only suggestion I have would be is to better set expectations during sales phase so the client will better know on what to expect. II was not expecting the amount of dust and debris created but as I mentioned it was handled very well. I highly recommend Wendel and this company!
