They did our radon mitigation on the place we bought. They walked us through everything, were very detailed, and always on time.

There is no way that you could have a better experience having a Radon mitigation system installed. Everyone was helpful, polite, thorough and neet in their work, and on time. I highly recommend using them! read more

I highly recommend Elliott & Associates (which is now part of Protect Environmental). They showed up when they promised and completed installation of a new mitigation system that morning. Radon level dropped from 5.0 to 0.4. There were 2 nitpicky items noted by the village inspector. Elliott promptly returned and addressed these and the system was approved on repeat inspection. They were a pleasure to deal with every step of the way. read more

I called Elliott and Associates when a mitigation system installed by another company failed to lower the radon readings in our basement to acceptable levels. Elliott's years of experience enabled him to diagnose the problem quickly; his technicians installed a second system in our garage, which dramatically reduced our radon levels and enabled us to reclaim our basement at long last. The technicians were prompt, professional, and informative. I would recommend that anyone with persistently high radon readings contact Elliott and Associates immediately; their work is simply first-rate! Charles C., Park Ridge, IL read more

Not all Radon mitigation companies are the same. I moved to my home in Sandwich IL. We worried about Radon causing Lung Cancer, and Radiation in the soil. We have 3 grandkids playing in our basement. Our existing system was installed with a 3 inch pipe and after googling the fan, the worst fan anyone could get. Rated Inexepensive. I hired Elliott for my parents home in Wheaton, therefore I used them again for Sandwich. Using Airthings Radon detector for 160 dollars from Home Depot online order only, our readings were 8.89 to 7.6 long term. Elliot Associates gave advice where to place it for a week, I had Radon everwhere . Elliott investaged found I needed two pipes one in our wine celler door opening, and pipes were undersized. They replaced the system with 4 inch pipe, and discovered no fire stopper openings were placed between the garage and the ceiling and wall. The system they installed was in side our garage to the rool. A properly sized fan in the attic. Our readings droped to .5 Pci from 8.89 long term measurements greater than a 2 day test. 50cm above the floor. Exact spot measured originally. Its been a week and they exceeded our expectations =average .5 PCi Our family is safe from Radiation and drinking water is safe, as well as Free from Radon causing Lung Cancer. My gradkids can safely play in our basement. This company not only mitigates, but redesigns using proven math and squarefootage. Drawings. Nothing is more important your family especially your wife with the grandkids. Nothing means more. Imagine what could happen to the family if Elliot and Associates are not helping? Cancer is nothing to ignore. Dave Hurd Sandwich read more

I want to say Elliott & Associates did a fantastic job very nice and neat and clean and looks very professional we couldn't be happier with the work and very responsible and we are grateful for his great service. Bill LoB read more

My original test results for my basement locations were 4.4 and 8.8. After they installed the system, the results were 0.7 and 0.8 which is absolutely amazing, especially since outside air is 0.5. The crew was fantastic and put up with all my dumb questions throughout the whole process. Elliott delivered more than he promised. read more

I had a very good experience with this company. They showed up on time, the crew was professional, and they explained the entire process in detail. The final cost came in at the low end of their estate range. read more

Elliott and Associates is one of the most positive experiences I've ever had with a contractor. I had a radon mitigation system put in in Feb. 2022. My experience: 1. Most importantly, the work was stellar. They went out of their way and spent extra-time to make the system exhaust piping inconspicuous on the exterior. In the basement, the work was minimally disruptive and the PVC pipe runs were efficient and well done. They did a good job of remembering to seal out of the way cracks that were found in an initial consultation. The work site was left very clean. HEPA vacuums were used for the safety of the workers and me when working with drilling (through the concrete slab and older toxic building materials). Finally, preliminary readings (with the caveat that its early still) from my home monitoring system show significant radon reduction. 2. I have never seen a contractor provide so much (relevant and insightful) documentation. There was a lot of specific information on the system to be installed and contextual information about radon and the system in the proposal, as well as pages of references (Elliot has worked on many, many houses in my area) with starting radon level, among other things. I work in consulting , a documentation-heavy industry. Usually contractors are fly by the seat of their pants, but Elliot runs a well-oiled and sophisticated client-communications operation. This is a good thing. I found all of it enriching. Every aspect of the install was photographed and I received a report within 30 minutes of completion; I didn't even need to leave work to see how the installation had went. The tech sent me text updates on his progress. They came out quickly. I received appointment reminders. Everything was painless. 3. All my needs were relayed to the techs installing the system. Oftentimes, the person you communicate with on a job is removed from the actual execution of it. This is usually an issue because any specifics you discuss with your contact do not get relayed to those who will implement it. If you have unique circumstances, it can be hard to get those taken care of. Elliot had relayed my detailed instructions to the tech who introduced himself and immediately rattled off the requests I had asked the office. In closing, and as the length of this review probably shows, I was very enthused by the work done by Elliot and Associates. read more

The technicians were personable, professional and worked quickly. They cleaned up thoroughly and we're out of the house in 2 1/2 hours. We will sleep better knowing the work is done and highly recommend them read more

Elliott & Assoc did Radon Mitigation in our home recently and they did a very good job. Dan and Dave were the technicians and that did an Excellent job. Efficient, Professional, Neat, Courteous and they explained exactly what they were doing. Great Job ! RP Orland Park read more

Just needed a radon retest after system installation, Elliott was recommended by my realtor. They were easy to schedule and prompt to show up, easy pickup and results same day as pickup! I'd recommend them for testing. read more

This company is the finest for anything associated with radon. I've used them for over 15 years and honestly if they don't know how to fix something than no one does--they truly are the experts in this field read more

Elliott & Associates provided personal service from the very first phone call. I was referred to them by a restoration company, which said they could evaluate the site, and install an exhaust system for a crawl space... which is similar to a radon system. Elliott took a personal interest in our issue, which turned out through no fault of theirs too require multiple visits and additional work. All the staff were helpful and courteous and reported back to Elliott their findings. Elliott followed up each time, and did not charge us for the extra trips to make sure everything was working properly. Elliott & Associates would be my first call if I were purchasing a house and needed a Radon test, a Radon system installed, or an exhaust system installed. Always appreciate when the owner of a business is available, returns your calls, and is fair in his dealings. Great job!!!! read more

I recently had a radon mitigation system installed by Elliot & Associates and honestly I could not be happier. They were quick, professional, etc. but what was most important to me was a significant reduction of radon level in my basement. These guys know what they do and they've done it for a long time. Look no further, call them. read more

If it were possible to give less than one star on yelp I would. I had an awful experience with Elliott and Associates. I understand the initial proposal is just an estimate with additional costs to be added in once the pros get a firm understanding of the work required. However, my quote more than doubled when Elliot's crew arrived at my home! When I expressed my concern, Elliot directed me to his "contract." Unfortunately for Elliot, his contract is as vague as his proposal. NOTHING in the contract prepares the customer for such a vast difference in price. Dealing with Elliot on the phone to discuss the misleading information I received was just as shady and confusing as his "contract." There are plenty of companies in the Chicagoland area that provide the same service at a reasonable price without the fraud and dishonesty of Elliot and his associates. Be warned. read more

Exceptional service. Communication was above and beyond expected. Service prompt and radon remediation system installed and explained with care. Results spectacular, both efficient and as aesthetically pleasing as possible. I only wish I had been aware of the increased radon levels in my home of 25 years prior to selling. Owner Elliott, his associate Ken, and the two technicians were professional and respectful of the stress and disorder involved with moving. Ken even called back a week after their service to be sure I was able to print copies of my invoice and work order although my issue was with my computer and not Elliott and Associates. I would recommend this company without reservation. read more

They have a great reputation in the area for all things radon, and it's warranted. We needed a new fan installed on our system. Our tech, Brandon, was extremely knowledgeable and really took the time to answer any questions we had, put us at ease, as we are new homeowners with two little kids. The system is working great. Couldn't recommend the company more. read more

We contacted Elliott & Assoc after our new home failed the radon test. As we were concerned for what the mitigation process would be, we were put at ease as soon as Tom answered the phone. That was the first contact, and it was just great. When Elliott came to our home, what he suggested was exactly what the home inspector had also suggested for the radon mitigation. That was the second contact with this company, also great. Phil showed up to do the actual work, on time and as scheduled. Third point of contact, and this company is batting a thousand! Kristine, in the office, is both pleasant and professional. Each contact with Elliott & Associates was remarkable. When you need radon mitigation, don't waste your time calling around. Other companies didn't even call us back. These guys are simply THE BEST! Elliott even called the next week, following up to ensure we were satisfied. We will recommend them to everyone. From the first point of contact to the follow up from the owner, this is a remarkable company. They deliver honest work for a fair price. read more

AVOID THIS COMPANY!!! Elliott & Associates does horrendous work with ZERO accountability. We have WATER IN OUR BASEMENT because of a job that was done improperly and unprofessionally, and the company has offered NO SOLUTION. I've never written a Yelp review before, but am so enraged and furious that I want other potential customers to know just how cheap, stingy and awful these guys are. Bottom line: After paying a premium, we got water in the basement. Why? It came in from the hole that Elliott & Associates had cut to install their radon pipe -- and then -- filled with foam. FOAM!!!!!!! ARE YOU KIDDING ME? When the water came in, it couldn't drain because Elliot & Associates had replaced our floor drain with a sealed one raised 1/4 inch off the floor. Immediately after the installation, our contractor noticed the botched job and suggested that we call back the radon guys to do the job right -- or else face the potential of water. We called many times after the installation to voice our disapproval, but got nowhere. Finally, when the worst-case scenario came true -- when water back coming through the hole where it very clearly read "Elliott & Associates," I got a callback. Immediately, the company's attitude was "This isn't my problem." After insisting that Elliott himself come out to explain the rationale behind why his company had designed the radon system the way they had, it became clear that the answer was pure, unequivocal laziness. (Me: "Please help me understand why you installed your radon system through here?"/ "Because there was an existing opening." / "Opening to what? Where does this go?" / "We think it's an old ventilation system." / "You think, or you know??!" Not only did Elliot not know, but he had no choice when faced with evidence of water coming in through where his men had cut into the wall except to begrudgingly, half-heartedly admit fault. ("If you want, we can take out the foam and put in concrete instead. That should water seal it.") And if it doesn't? I insisted. What are we supposed to do if water comes in again? I showed him the floor drain in the basement where his company had installed a raised drain. Elliot's response? There was "no other choice" except to use a raised one because the drains his company uses don't fit in our pipe. (Me: "Using a drain that is raised above the floor negates the purpose of having a drain. Why didn't you install this properly? // Elliot's reply: "Look, I'm a radon guy. Plumbing issues are not in the scope of our contract." // "Wait a minute," I said. "You mean making a basement properly sealed so that radon doesn't come in through the floor drain isn't the responsibility of the radon company?" He back-peddled. "What I'm saying is that we didn't know when we gave your quote that the drains we usually install didn't fit. It's not in the scope of our contract to fix your drain." WHY WEREN'T WE TOLD THIS?? WHAT KIND OF A PROFESSIONAL HIDES INFORMATION FROM A CUSTOMER? Only a company that cuts corners and races through jobs instead of telling their customers what's going on and trying to find a solution. I reminded him that we had a dry basement UNTIL ELLIOTT'S IMPROPERLY DONE JOB CAUSED WATER IN OUR BASEMENT... and now, because of him, it had no place to drain! Without offering an apology, he offered to send one of his men to put in another drain. Today, that worker arrived. When I walked into my kitchen, I saw him at the kitchen sink. THE WORKER WAS MIXING CONCRETE IN MY KITCHEN SINK. I said, almost in shock - "Are you mixing concrete over the dishes in my sink?" His response: "I couldn't find a water source in the basement. I'll clean up after I'm done." He then proceeded to carry the mixture in his bare hands, dripping wet concrete as he went over the kitchen floor and down the carpeted basement stairs. WHAT???? Maybe at the beginning of his 30-year career, Elliot was professional. Perhaps back then he actually cared about the jobs that he did or gave consideration to the customers whom he served. But those days are long, long gone. The job completed in our basement is not only a horrible eye-sore, but the lack of professionalism is absolutely abhorrent. And the worst part has been that any of our questioning of his company's work has been met with "I've been in this business for over 30 years." The last interaction we had ended in raised voices from both of us. Elliot repeated to me, again and again, that it's "not in his scope of work" to fix the problems HE CAUSED and suggested that we "go back to using the drain we had before." Then, he dismissed me, saying that this conversation was going nowhere and that he had "another potential customer waiting." This is beyond-the-pale kind of unprofessionalism. If you are considering hiring Elliott & Associates, look elsewhere for a business owner willing to stand by their work and help find solutions for their customers. DO NOT DO BUSINESS WITH THIS COMPANY!. read more

Professional, timely, courteous and good workmanship! If you need a radon mitigation system, consider this company.

Elliot inspected my home and came with a plan for the system installation. He promised to install "premium" system for premium price. I decided to go with this company even though they are charging lot more than others and end result is disaster. There is zero communication between owner and workers. The installed system is not as promised. I am surprised that they made some fundamental mistakes even though they are in business for 30 years and charge top dollar. Elliot recommends 4 inch system and you think it is 4 inch all the way but only part of system is 4 inch and rest is 3 inch system. This does not make any engineering sense as the system efficiency is pretty much limited by 3 inch pipe. Elliot charges around $400 more for 4 inch system! They did not even install energy star rated fan which costs just $10 more than the fan they installed (~$150). Radon mitigation seems like highly profitable business! It just costs less than $300 for parts and rest $1400 is profit and 2 hours of labor. These companies make it sound lot more complicated than it is! read more
