We purchased our house from someone who had hired them initially. So we are a license transfer of warranty. We had them come out to our house twice to service some water issues and they very prompt, courteous and did an excellent job. It’s been around three years now and all is dry.

“It was very good. They were prompt, came exactly when they were supposed to, did what they were supposed to do, and the crew was pleasant. It was the type of experience that you’d want if someone was doing work in your home. The job took a couple of days and it has worked just fine.”

Very good customer service and communication about the project at hand. I would highly recommend Great Lakes Waterproofing.

Very quick turn-around on work. Helpful people. Finally, I’m excited to be a home-owner!

I researched this company and discovered it invented the outside-injection process in the 1970s for sealing basements without having to dig up the ground/foundation. They understand the concept that, if the water is coming from the outside, you need to treat it from the outside to keep the water off the wall! Other companies only have the inside systems that don't address the source (external) of the water. Great Lakes has a variety of options, and the volclay-bentonite they provided for my house permanently stopped the water and mold!
