Thank you George H for getting my crack fixed the next day ! Quick service thank you!

Great communication skills very professional and Informative

From start to finish, my experience with Perma-Seal was top-notch. First off, Matt was very professional and thorough in assessing the overall situation and was excellent at explaining why the things needing repair had gotten to be a problem, and how the recommended repairs would fix things and keep them from happening again. As it turned out, neither he or I had noticed the sump pump problem, and when I finally saw it some days later, Matt came out on a Sunday morning to figure it out and get that included in the other work Perma-Seal was going to be doing.

On the day the work was scheduled to be done, Marcos and his crew of 5 showed up right on time and got right to work. Everyone was professional, polite and happy to answer the questions I had – which truth be told were not many because the crew had given me detailed explanations of what they’d be doing up front. It was easy to tell by watching these guys that they were well trained and knew exactly what they were doing. They were also very hard working and got everything done in one day – which was surprising to me given all they had to do, but apparently not to them. Overall, I’d be happy to have a crew like this one to do any work I needed done.

Jesse was very through in identigying and explaining the problem

John was terrific! From the very start when he came out to my home to talk about the basement waterproofing needed in my home to the numerous times I called him with follow up questions and concerns after signing the contract for Perma-Seal to do the job. John was always available and reassuring. He took the time with me and explained things very well for me to understand. He never was pushy with me. I never felt pressured with him unlike some salespeople I have encountered in the past with other companies. Thank you, John!

I want to thank Crew Chief Guillermo for all of his hard work on waterproofing our basement. He and his crew worked very hard over the two days they were here. Guillermo kept me informed of the progress of the work being done. He was patient and gave me his time for me to ask questions and raise any concerns I had along the way. He and his crew were professional in the way they worked. He and his crew were respectful of my property and cleaned up well after finishing their work. My wife and I are now feeling relieved that we will finally have a dry basement! Thank you.

Jim G was out today. He performed a hose test and found the leak. He showed a presentation on how we can fix. Very professinal.

Jim G was out today. He explained about wall liner and the battery back up system with defender. He was very professional and easy to talk to.

On 4/25/25 we received service from Manual & Jorge to install a new Basement Defender System and flush out current pipe system. We were advised by Manual that this flushing was not needed due to the area we are in and our bill was reduced by $730. We would like to thank Manual and Jorge for the excellent service, and friendly manner in which they took care of our questions and their honesty. We feel that it is necessary to recognize good service and honesty in good employees.

Perfecto showed up on time and ran the job and was professional and worked hard in a difficult environment and was able to add support to my beam and completed job in a timely manner. I highly recommend permanent-seal for great customer service. Thank you!

George H came out for an estimate on my settling foundation. The solution for piers will fix the issue. Thank you Perma-Seal

I recently had piers installed to correct a problem of the foundation sinking. I was consistently provided with updates and detail explanation of the project.
From the original assessment conducted by Jim G, to the actual construction overseen by project leader Hugo M, the project was professionally performed. I would recommend use of Perma Seal for similar projects.

Thank you George H for the estimate on crawlspace insulation !

Thank you George H for the free inspection !

Thank you George Heller would give 10 stars ! Sealing up my crawlspace / crack repairs

Perfecto and his crew were considerate when working on my crawl space. They wore covers on their shoes and put a tarp on their path to keep my house clean. They worked hard to be done by the time I had to leave.

Jessie was awesome!

Antonio Garcia provided a lot of great information and was very knowledgeable in what is required for waterproofing my crawl space. He answered all my questions and made me at ease. He presented great customer service and exhibited professionalism.

Antonio Garcia was great! He was knowledgeable and polite. He was always on time. We would recommend to anyone who need your services.

I worked with Josue Hernandez on a project to encapsulate our crawlspace. Upon arrival, he assessed what needed to be done, and was very thorough in explaining the issue so that I felt well informed on our options. There were some very difficult aspects to our project (shape and entries to our crawlspace) but he did a great job to accommodate. We are pleased with the final result.

Jake Showed up early and was able to explain and assuage our fears after discovering our underground discharge line had failed. Getting it replaced will give us peace of mind and security that our crawlspace stays dry. 5 Stars!

George H helped me seal my crawlspace and encapsulate ! Insulation for the walls

George Heller quote for my battery backup sump system !

Andres Rincon completed a very careful and thorough installation of my nee Defender Back-Up system. He also provided a clear and concise explanation of how the new system operates.

I have been very happy with Perma-Seal’s overall services over the years. Having Andres on the Perma-Seal team is definitely a continued reason to be happy!

Great job done by Victor and his crew.

Very pleasant, efficient service with Tomas. Explained procedure, showed all the steps as completed. Cleaned inside area, outside area professionally completed. Highly recommend Permaseal.

Alejandro Lopez did a great job. I was happy that he let me watch him work and explained each device and walk me through how everything works. Great work thank you!

Christian was a pleasure to work with. Explained everything thoroughly and we look forward to the work being done.

George Heller was great with estimate on our concrete – thank you for your great service !

Met with Mike B. and Jack regarding concrete lifting and leveling at two separate residences. This was after receiving two competitive bids in the two days prior.

Hands down, the level of knowledge and detail that Mike B. brought to the table were unparalleled. I am extraordinarily detail oriented and as a result asked hundreds of questions and raised dozens of challenges. Mike rose to the occasion and patiently and thoroughly addressed every one of my concerns.

There were no high pressure sales tactics, and pleasantly, no focus drift to all the other services that Perma-Seal offers. The quotations / proposals provided same-day by Mike were far and away the most comprehensive I received, including site diagrams and itemized work to be performed. Despite heading into the Easter holiday weekend, Mike “burned the midnight oil” and revised the proposals to alleviate any concerns I had, and he and the Team at Perma-Seal were willing to work on pricing to meet comparable bids. I expected a large firm like Perma-Seal to be generally inflexible, but was very pleasantly surprised to be proven wrong in this regard.

Finalization of the contract(s) and scheduling work were also a breeze. I’ve already recommended Mike B. and the Perma-Seal team to a co-worker.

Jim G came out and was great. He was very quick and efficient. He showed me a video on poly level that was very informative. A very professional appointment.

Christian gave us a fair price to level our front walkway. And it’s getting done tomorrow.

Thank you George H for the great experience ! Look forward to having a new egress window / concrete lifted and leveled !

George H was efficient and quick to respond tp our needs. It is appreciated as we move to sell the home.

Dick was friendly, showed up in a timely manner and took the time to explain each step in the process. He was honest and did not try to oversell us things we didnt need. He knows his products very well and was great to work with.

Jim G arrive to my house on time. He was very professional. Inspected my garage and sidewalk and found the garage to be structurally sound. Only the sidewalk and garage floor was settling. Appreciate the honesty.

Jim G was out today and discussed different areas we can lift concrete to help keep water away from the foundation. He was very professional and courteous.

Jake Baron recently performed annual maintenance check. Jake has tremendous business acumen and was very thorough in his review and recommended service. I was very appreciative of his professionalism and attention to detail.

Anthony gave a great explanation of options, and did a very thorough inspection. I was very impressed!

My technician, Alejandro Lopez, was professional, thorough, knowledgeable, friendly, and honest. He encouraged me to accompany him while inspecting my property (interior and exterior), answered all my questions, then gave pressure-free recommendations based on his inspections. A+++

The PermaSeal representative that came out today was very friendly and knowledgeable. He gave me a lot of different options for upgrading an existing sump pump. He also performed the maintenance service quickly and efficiently. Great experience!

Shane was always honest with us, in the course of his investigation, step-by-step: It was a confusing situation: the blue transmitter box was giving a false reading: The “WIFI” indicator was green, even though we do not have a WIFI subscription – so it should have been red. The “Active” indicator was red, which was correct, since we do not have a subscription. The “Alert” indicator was red, which was incorrect, since the system was operational, so it should have been green.

(1) Shane swapped-out the blue transmitter box with a new one that was working. The original blue transmitter box was still under warranty (2024). “Alert” indicator is now green, which is correct. The “WIFI” and “Active” indicators are red, which is correct.

(2) In the course of his testing, Shane noticed that the Primary pump was erratic, sometimes working, sometimes not (Intermittent). It had been installed by Perma-Seal in July 2018, so it was nearly 7 years of age and had seen a lot of use in the past few seasons. So Shane recommended replacing it now, instead of waiting for something to happen and being suddenly helpless in an emergency flooding situation. After due consideration, my wife and I both agreed with Shane’s assessment, so we decided to have Shane install the new Zoeller Primary Pump. The Battery Backup Pump is already operational.

Antonio was very thorough. He explained exactly what he was doing which made feel very comfortable. He did a great job and he also has good customer service skills

Christian gave a thorough inspection. Very pleasant to talk with as well.

BIG thank you to Anthony Modica. I like the way he built different options for me instead of saying “I NEED” to do something. He was not pushy, and he was very knowledgeable

Antonia was on time helpful in his evaluation & recommendations was very pleased!!

Alejandro Lopez was very attentive and on time. It was a busy day. He called 1st, arrived and took care of my inspection. Great job Mr. Lopez!

Nick was thorough and very informative. Explained each step of the evaluation process and the insulation process.

Nick was thorough and efficient. He explained everything to the satisfaction. I was pleasantly surprised a the affordable cost.

Nick gave a very thorough exam of our attic and an explanation of what will necessary to bring our home up to code and health standards. He was helpful and informative. Thank you!

Victor did a great job. He thoroughly explained the process, was very personable and professional.

Antonio was a real pro in installing my foam spray into my knee wall, I think that’s what you call it….I pulled out all of the old 50 yr old fiberglass insulation to make his job that much easier. He took me for a tour of his work after he was done, using his flashlight to point out everything.

Very informative

Enrique Morales and his crew did an excellent job at insulating the attic above the garage and the whole house! They had to remove the existing old insulation, seal everything up, and then install new insulation in the attic above the house as the garage and house are separate. He allowed and offered me to see after each step of the process as they went along. They were very respectful, pleasant to work with, and they cleaned up everything nicely once they were finished. I am looking forward to reaping the benefits of having this done to our home. Thank you Permaseal and your staff for yet another job well done!!

Thank you to Chuck, our sales rep, Eric, our lead installer, and Kyle, we appreciated your professionalism, strong work ethic, dependability. We would trust Permaseal for all of our needs. Thank you for your patience with our scheduling demands all the way in Somonauk. Just all around excellent experience. A++

Jesse was thorough and explained everything!

Alejandro Lopez was professional, knowledgeable, and friendly. We really appreciate his help in with this process.
