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.

Concrete Foundation Raise
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."

Foundation, Basement or Crawlspace - Waterproofing / Encapsulation
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.
Response from Perma-Seal Basement Systems
"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.

I have hired Permaseal to fix my unleveled patio concrete floor that was and still causing rain water to get to my basement, I have paid them $2,014.33 as down payment, they showed up one month later for the job, which is injecting foam under the concrete slab to lift it back to its original correct level. I came back home that day to find out that they have left and that the concrete slab was not only still unleveled, but they cracked it and patched it on multiple locations. I have called their customer care number more than a dozen times in attempt to understand what is going on, and on each occasion, I was told that the project manager was going to contact me back, which never happened until i made the next call, They have finally explained to me over the phone that it was the best they could do and that they could not fix my patio floor. I asked for a refund and did not hear back. I have documented pictures of before and after showing that the job was not done and cancelled the check with the remaining balance. I have not heard anything back from them since then, until i started getting debt collectors' emails on December the 5th from a business called FCR Services.

review update 3/12/26
This has been the biggest waste of time and money. I do not recommend this company for anything, do not bother even asking for a quote. They sent one of their reps over to give me an estimate. I initially wanted to get concrete put in instead of this but they insisted they could do a better job for cheaper so I accepted. The crew came and were nice and polite but as soon as I inspected their work issues started to appear. First I was told they would leave room for Ethernet to be run when they did not, now I have to remove a bunch of spray foam and reapply it. I was told they would seal (not fill) the joists from the outside, they did not (air can be felt whenever its windy, so much so the plastic bags they used to seal the flooring can be seen moving in the wind with the door closed). My crawl space now has higher humidity and worse temperatures than ever before. They have been over several times since and refuse to fix their poor installation.
I am deeply disappointed with Perma-Seal's crawl space encapsulation service. Despite being promised a significant increase in overall temperature, the $2,500 system has delivered, at best, a negligible 2-degree change only visible on a thermometer. The quality of installation is shockingly poor for a professional company. Within three days, the sealing tape is already peeling, the vapor barrier was improperly installed around the frame (leaving gaps where I can feel a cold breeze), and spray foam is falling off. The materials feel cheap?the R-11 insulation shows its low quality, and the liner is so flimsy it can't be walked on without risking tears. The most frustrating part is that fixing their sealing errors would require removing and ruining all the insulation, leaving me stuck with a fundamentally flawed installation. I regret not choosing another company or a different solution altogether, as this experience has been a complete waste of money and trust.
Response from Perma-Seal Basement Systems
"Thank you for sharing your experience with us. We're truly sorry to hear about the issues you encountered with the encapsulation project. It's important to us that our customers feel heard and are satisfied with the services provided. We understand the frustration caused by the installation process as well. To address your concerns, we have scheduled a warranty service call for January 5, 2026, to reassess the situation and work towards a resolution. We appreciate your patience and are committed to resolving this matter to your satisfaction. If you have any further questions or need additional assistance, please don't hesitate to reach out to our Customer Experience Manager, Bill Jirsa, directly at 630-432-1779 or bjirsa@permaseal.net."

Make the following review as professional sounding as possible...The employees that came out to raise our sunken garage floor and footing were wonderful but beware of corporate. I am extremely happy with the work the men did on my foundation but corporate is another matter. They raised my foundation in early December and they were to place the poly level undeneath the concrete the next week to fill the void between the raised floor and earth. However corporate put end of the year sales and managerial bonuses ahead of the customer. I'm not to receive the poly level until April as it stands now because of the frost line. This oversight on corporate's part makes my garage unusable for the entire snowy Chicago winter. The company left me without the use of my garage for the entire upcoming winter season. If I would have been told that only half the job could of been completed I would have postponed the work until spring. No one informed me of the oversight on the company's part
