David came out and explained about Real Seal waterproofing service and process, all went very smoothly and the company provided the estimate along with their information in a timely manner - within a few days George came out and he communicated everything he was doing and was very nice and respectful of our lawn. Working with David & George was a great experience and would recommend this company. Mike & Geri Golonka Service done 9/2025

We have worked with Real Seal on multiple projects on our home. They offer top-notch service, responsiveness, follow-through, and most importantly, great work. We had them polyjack some of our sidewalks, replace a couple of areas of sidewalk, and seal a leaky side of our home, and we are so pleased with how it turned out. Real Seal is our go-to for all foundation/flood mitigation needs, and I have recommended their services to others countless times. They are the best!

I like that I felt everyone was straight up and honest. No gimmicks, gotchas, or sales pitches. Just this is how we would fix it and here is the price. The guy who did the work did an amazing job and the price was reasonable.

Greg, sales, did a great job determining what work was needed. All communications were helpful. Juan & his team did a great job performing the work checking if my wife or I had any questions. They protected our wood floors upstairs and basement flooring. They cleaned up when they were done. Very friendly & helpful.
