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!

Foundation Repair in Chicago, IL

During the last 3 months, I have been attempting to solve a water leakage problem at my property in Chicago. It is an expensive single family home that I have been fortunate enough to rent to very nice, responsible people. Unfortunately, I have had sewer smelling water entering the lower level every time it rained. It is a finished living area. Let me tell you something, I have been rehabbing and building for 20 years. I have been a Real Estate broker for 20 as well. I tell people all the time, You can never have all three…speed, competence and price. You always have to pick two. Well, for the first time in my career, Dan McGowan gave me all three. He was fast, considerate, competent and did not try to rip me off. I also felt Steve was out for my interest every minute. This was a rare experience for me. I just wanted to let you know that you have some great employees. However you found them, I would write it down. I will always call your company first. I am also putting your numbers in my newsletter for all to see.

Basement Windows Replacement in Bartlett, IL

We needed our single pane basement windows replaced. I scheduled several companies for bids, Perma-Seal had the lowest bid by a few thousand dollars, but the quality of the windows is just as good if not better than the competition. The install was great, no real mess to speak of. The installers took their time and did the job right. I will use Perma-Seal again in the future if needed. Very pleased with the whole experience.

Basement Waterproofing in Antioch, IL

You are very fortunate to have Dan McGowan, Maurillio and crew in your employ. Dan was very informative and answered all my questions. It was his demeanor compared to another company that I decided to go with your company. I would also like to add that Maurillio and crew were on time and very polite and worked very diligently. Maurillio made sure everything was cleaned before leaving. Thank you. You have a great company and I will “pass it on.”

Basement Waterproofing in Lombard, IL

I cannot even begin to thank you enough for all of your help with the location of the entry point of the water seepage in my basement. Your professionalism, friendliness and kindness are so very much appreciated. Perma-Seal is the best ever because of people like you! Thank you very much for all of your help.

Foundation Repair in Willowbrook, IL

I requested an estimate for a leak in foundation. Dan McGowan came out,did a preliminary review and came back to dig out my foundation to find the crack. He only found a poor job by the previous owner in some brick work at the top of the foundation. He spent a couple of hours and would not bill me. A welcome experience with an honest contractor. I would definitely recommend Perma-Seal for giving a honest foundation repair estimate and being extremely helpful even when there was no apparent monetary gain to be had.

Crawl Space in Arlington Heights, IL
I had a top notch experience with the Perma-Seal folks... from estimating, through installation, and subsequent warranty work and followup. It was almost 2 years ago when I had all the work performed. Everyone was punctual for their appointments, very knowledgeable and informative on what to expect, how things would work, and what to watch. The end result looks very similar to the other "after" pictures posted... very clean and professional. No mess left after the work. I no longer have that musty smell in the crawl, and I actually store things in there now. After the first year I did have an issue with the pump. They responded quickly and took care of the issue (replaced pump) at no cost. Everything continues to work like a charm. On top of it... after another year went by... I recently received a call to schedule a free inspection and checkup. They just were here and checked everything out... all still working great.... and free inspection as well. Can't beat that... they just checked everything out, made sure all was working fine, mentioned a few things I could do for added services but was not "pushy" by no means on the sell... just let me know what was available. Excellent customer focus, followup and support. I am extremely happy I went with these folks.... as I said, my experience has been top notch.
