Customer Reviews and Testimonials

I had the option of using another contractor, but I chose to have Perma-Seal perform the interior crack repairs because I trust their years of experience and excellent reputation as a foundation repair company in Chicago.

I was very satisfied with the drain tile and sump pump installation that was done by the Perma-Seal waterproofing crew. Jim went out of his way to make sure that I was happy and stayed informed with the work that they did.

The Perma-Seal consultant was very informative and patient, and the crew was quick and very clean when they worked on my basement. The finished product looks beautiful!

Juan from Perma-Seal was very helpful when he and his waterproofing crew worked on my basement. I would gladly welcome them back!

The Perma-Seal crew did a good job waterproofing my basement. You waterproofed my basement one week before our record rainfall and I had not one drop through those fixed cracks!

Bill Nicholson of Perma-Seal was very professional, polite and thorough. He did not rush, and even asked me if I had any concerns or questions. I will have him come back on next year when I have a new sump pump installed!

A+ for Perma-Seal! They were so likable, courteous and well-mannered when they were in my home. They really went beyond my expectations and everything was as clean as a whistle when they left!

The Perma-Seal service tech was professional and he completed the sump pump exchange without a problem. I will continue to recommend your company!

Dealing with Perma-Seal was a great experience from the small repair price to dealing with the people. Our basement consultant answered every questions and explained everything clearly. Awesome job on our basement!

If I ever need Perma-Seal’s services again, I would appreciate it if you would send out the very same foreman – Mr. Blas and crew. Thank you for your help on my basement!
