"We used Perma Seal for several big projects—waterproofing our basement and replacing our concrete back yard and sidewalks. We had drain tiles, sump pumps and a dehumidifier installed, along with extensive concrete work outside. We dealt with a variety of crews and found everyone to be very communicative, professional, and knowledgeable. They did great work and kept us informed at every step of the process. When we had a questions, they were very responsive. All in all, we'd recommend and use them again."

"I’m extremely satisfied with Regional. We had three sump pumps that needed to be replaced (primary, secondary, and water powered backup). The quote was very reasonable, and they were able to do the work shortly after their initial visit. They replaced everything with Liberty pumps. Justin and Erich did the work and they were very professional. We had them quote out a couple of other items (replacing water heater, etc) and those quotes were also very reasonable. I will definitely hire them for future jobs."
