The team at key waterproofing did an exceptional job, did the job quickly, and did a better clean up than any other contractor that I've worked with before. We ran into a small snafu and the team quickly made me aware, addressed and corrected things

Stephen was the guy who contacted me first. He was very knowledgeable and direct. I appreciated that. The install guys were not the quickest but very good at their job. The job took time over a couple of days. But when they left you didn't know they were there. Thorough and clean for a basement job. Thank you.

They came out right away even though everyone and their brother is having wet basement issues. It took a little while to schedule but again that is because of all the torrential down pours we have been having - they were really backed up! Problem resolved for less than I what I was expecting. AND the job was in a basement crawl space - which is horrible to work in. Their crew was terrific!!

I knew that I needed waterproofing for the front of my basement as water would sometimes leak in during very heavy rain. After the work began, it was discovered that the entire perimeter of the basement needed the drainage system replace. This meant almost 4 times as much footage needed to be worked on, yet the cost was a little over double, not 4 times as much. I was very relieved when I was given that revised estimate. The work looks to be high quality, but I especially like that the work is guaranteed for the life of the home, even after I sell it.

Very fast and efficient, I had a French drain installed along with a newer sump pump and backup pump that is battery powered so if I lose power can still keep it going. There is a problem with the secondary pump something inside wasn't right (not their fault) but they have been communicative and will come out to fix/replace it for me. Great people ! Steven and Wendell have been very helpful

Soon after recently moving into my new home, a series of storms caused water to rise up across the basement floor. Several contractors assessed the situation and provided estimates. Ed from Key Waterproofing Construction was the most knowledgeable of those inspectors. He clearly explained the cause and recommended solution, and patiently answered all my questions. Also, no hard sell, lifetime warranty and the best price. Wendell and the rest of the crew were professional in all respects from start to finish. My basement is now clean, dry and usable. I would not hesitate to recommend Key Waterproofing to family and friends.

Wendell and Ed are a great team. As a first time home owner who experienced flooding after 1 month of ownership, Iâ ve been extremely stressed over the last year anytime it rains. This team alleviated all of my concerns and continued to support me until I fully understood what they were planning and also any little concerns I had along the way. Their prices were very fair (almost half of the competitors for the same service) because they donâ t try to take extra. They charge a fair price for the work. My basement is finally dry with a working sump pump and I am grateful I hired them!

Both Stephen and Wendell were fantastic! They were happy to answer any and all of my questions and work with me to find the best solution for our space. The price was also over $1K less than the competitors and they didn't try to upsell us on anything that we didn't need. We haven't had any serious rain yet, but the small squalls that have come through haven't shown any signs of leaking like the basement used to.
