Customer Reviews and Testimonials

Excellent service and professionalism from start to finish, not to mention the lifetime guarantee! Will continue to recommend this company to friends!

I felt dumb because I didn’t know what I needed for my house. My front door had a gap at the bottom and its made my utility bills higher. I was compaining to a guy friend and he said call Perma-Seal. They were very helpful and explained every thing perfectly. Not only that but they were able to fix that and a problem with my foundation I didnt know I had.

Very courteous and knowledgeable staff. Very helpful when my old sump pump gave up the ghost during a heavy rain.

My basement is as dry as can be after they waterproofed it. I am completely thrilled with the results I had. There’s not one negative thing about this whole experience.

I live in Tinley Park and I called Perma-Seal because my basement was leaking after every rain and they came out and gave a price quote. It was a lot of money to spend so I called another waterproofing company to get a second opinion. They was only dollars difference but there attitude and willingness to fix the problem made me choose them over the other people. They were all so nice and professional and worked quickly. We had our first big rain yesterday and there is no water in my basement.

We had a great experience using Perma-Seal. The sales guy was really professional, took plenty of time to explain why the water seepage happens, showed us a really well designed computer presentation offered solutions and then followed up with a written bid. We compared 3 other companies and checked out references before having the work done by Perma-Seal.

Had my foundation repaired – I just had my foundation repaired by them. They worked very quickly for the middle of winter and I was very impressed by the way they worked and surprised me by the outcome.

Always had great service! – I had a great experience with Perma-Seal,both times that I used them. They repaired a leak in the basement of my previous home 17 years ago, and they did work in my current home in the fall of 2009, and I have never had water in my basement after their repairs. The estimators are always very thorough and make sure that I understand the process and cost involved, and the crew always delivers. Highly recommended!

Everything was great!! Very Professional. Price was MUCH less than I expected it to be. Would very highly recommend.

Professionals that saved me from wasting a lot of money, and they did high quality, on time, professional work. I received other bids for over $3,000 to fix a leak that I had. Dan McGowan, the Perma-Seal,representative quickly explained that Perma-Seal’s proprietary process would get the job done with a warranty for around $200.Crew showed up on time. Done in 25 minutes. Work area left cleaner than before they started. Lifetime warranty on the seal. What could be better? You can trust Dan with his estimates and suggestions. You can trust that Perma-Seal,will deliver the goods.
