Concrete Foundation - Repair
The job was done by Victor. When he came to the house he introduced himself in a professional manner. He looked at the area of repair and did a test to confirm the cause of the problem. He showed me the problem and advised what the solution would be. He took extreme measures to lay plastic liner on the floor to prevent from damaging the floor and collect any debris. When finished, he explained what he had done and what we should look for in the next few days when testing the repair. I would ask for him to come again if I had any other repairs to be done .

I have had smaller critters under concrete porch for years but this year a groundhog moved in and commenced tunneling, so had to ‘void fill’ the space. The crew, Jose Martin and Alex, were very professional and thorough and did an excellent job! I am very pleased with the outcome!

Inspection Service
This is not your average complaint; I sincerely hope this review saves other consumers from doing business with the incompetent team at Permaseal. After 3 long years of battling Permaseal to do the right thing, I am conceding to the fact that they are a classless business with terrible leadership. Suffice it to say, if you?re looking for a company that actually solves problems, keep looking; there are other more reputable and capable waterproofing companies out there. My experience has been a masterclass in misdiagnosis, short-term fixes, and a complete failure to address root cause issues. Instead of identifying and resolving the underlying problem, they repeatedly chased symptoms?confidently assuring me each time that the issue was ?fixed,? only for it to return again and again. What?s most frustrating isn?t just the inconvenience?it?s the cost of their incompetence. Their repeated missteps directly led to significant, avoidable expenses on my end. Decisions were made based on th

"We take feedback like this very seriously, and we strongly disagree with the characterization that your concerns have been ignored or dismissed. Over the past three years, our team has made multiple attempts to work with you, assess the situation, and provide solutions based on the conditions observed at the time of each visit. Waterproofing and foundation-related issues can be complex, and in some cases conditions evolve, requiring adjustments to the approach. That said, our intent has always been to address the problem thoroughly and responsibly?not to provide temporary fixes. We understand your frustration, but it is not accurate to suggest there has been a lack of effort or unwillingness to engage on our part.

Doro was a pro when it came to doing the work. He saw what was needed, explained the work process and what caused problems. Would want Doro to be the person to come out again if I needed any work.

Concrete Foundation Raise
$1,300
Per my landscape contractor I requested a quote on patio leveling with a 1" raised pitch toward the back of the yard. After 2 conversations with salesman about this specific request, I put a downpayment and the install crew came out. Before work began I again said the scope was leveling with 1" pitch toward back of the yard. The crew foreman acknowledged. After work was done, I expressed concern that there was no 1" pitch, rather 1/4" pitch. After expressing my concerns to the office, they offered to come bacf out with increased risk of cracking the existing cement. I declined for obvious reasons. The collections agent said page 10 of the contract says this process is only to 'stabilize' the concrete. After BBB complaint, Bill Jirsa said the 1" is only a 'target'. No one discussed this during estimate discussions or installation. Nowhere on their website does it discuss this is only to 'stabilize' or it only guarantees 'target' raising. The water is still pooling on my patio.
Response from Perma-Seal Basement Systems
"Thank you for taking the time to share your feedback. We understand how frustrating it can be when the outcome of a project does not meet expectations, and we appreciate the opportunity to address your concerns. Our team strives to be transparent about the nature of concrete lifting work. Because this type of service involves existing slab conditions and other variables, certain adjustments are approached as best-effort targets rather than precise guarantees. These factors can sometimes impact the final results. That said, we have made several attempts to work with you in good faith and explore a reasonable resolution. As discussed previously, we even offered a goodwill adjustment in an effort to help bring the matter to a close. We remain committed to finding a constructive path forward. The project work has been completed, and there is still an outstanding balance related to the services provided. We would welcome the opportunity to speak with you directly and continue working toward a mutually agreeable resolution. Please feel free to contact Bill Jirsa 630-432-1779 so we can assist further."

I am very impressed and extremely satisfied with the professionalism, expertise, competence, and customer orientation the whole Perma-Seal team displayed during recent work completed on sidewalk leveling and basement sealing projects on my home. Work scope, costs, and timing were explained patiently and in detail by George Heller up front. The sidewalk leveling work from Doro went routinely, everything on time with excellent results. The basement sealing work was a bit trickier, as electrical wires and a pipe bundle all bunched together around the main sewer line provided multiple leak paths and required a second attempt to completely resolve. Doro, Ramon, and Waldo went beyond the originally contracted scope to ensure all potential leak paths were sealed off. They didn?t care what the contract said, their focus was on my complete satisfaction, no excuses, no shortcuts. Perma-Seal stands behind their commitments and I would not hesitate to call on them again.

"Thank you for the thoughtful review, [Consumer Name Removed] . We?re glad you were impressed with the team?s professionalism and communication, and that George, Doro, Ramon, and Usbaldo delivered great results on both the sidewalk leveling and basement sealing. We appreciate your patience as we worked through the tougher leak paths, and we?re proud that the crew went the extra mile to make sure everything was fully resolved. Thanks again for trusting Perma-Seal?we?ll be here anytime you need us."

Insulation - Install or Upgrade
Perma-Seal was out to insulate my attic this week and did an excellent job. David did a thorough inspection, explained everything, answered our questions, and even told us that we didn’t need certain work that we thought we needed. He was very honest, polite and personable, and gave us a fair quote with some options without being pushy. Luis and his crew began the work two days later. They were prompt, courteous, professional and knowledgeable. Luis explained how the project would be done and shared progress photos with me along the way. He even curtained off the area around the attic ladder to contain any waste and cleaned up everything perfectly. I would highly recommend Perma-Seal to anyone who is considering their services.

Concrete Foundation Raise
We have lived in our house for 10 years. Right after we moved in there was water in the crawlspace and we hired Permaseal to do drain tile. We've had no water issues for 10 years. This year we finally decided to do something about the settling in the addition and again hired Permaseal to install piers around the foundation (interior and exterior). Hugo M. and his team did an outstanding job, working through some very cold days, installing everything as planned and at each moment stopping to show us the work and the progress. The work required going through the drain tile on the interior pier locations and the team reinstalled the drain tile system before pouring the final concrete. The work was really well done and everything was left clean and picked up, which is remarkable considering the scope of the work.
Response from Perma-Seal Basement Systems
"Thank you for sharing your experience with us! We are delighted to hear that you chose Perma-Seal again for your foundation needs and that Hugo and his team provided outstanding service. It's great to know that they kept you informed throughout the process and ensured everything was installed as planned, even in challenging weather conditions. We're also pleased that the team maintained a clean work area despite the complexity of the job. Your satisfaction is our top priority, and we appreciate your continued trust in Perma-Seal. If you need anything else in the future, please don't hesitate to reach out."

The crew came out on this cold January day and fixed the crack in my foundation and sealed it to prevent seepage. I’ll know for sure when the spring rains come if it was a success. From the pictures they sent me, I’m very confident there’ll be no more water coming into my basement.
