I just want to say that Tim did an outstanding job with the installation of my radon system.  He and his staff are professionals and experts in the field. If you feel as if you need to protect yourself and your family from radon exposure, Tim Poffenbarger is the person to call.  Do not hesitate to contact him and set up an onsite inspection.  After all, there is nothing more important than protecting our loved ones.

Dear Homeowners, First let me say you should never get an estimate over the phone if your house has different or unique foundation types. You need a company like Tim's that sends out a representative to examine your exact situation. Tim was easy to talk to over the phone, asked many questions about our house characteristics and answered many of my questions before he decided that it would be necessary to come out to inspect the house in order to give me an estimate that addressed our home characteristics. He examined our home and listened to my concerns. His estimate was based on the facts of our two different types of foundations. Everything about his company and crew was absolutely first rate. When they pulled up in our driveway to mediate our radon and opened their work trailer,  I knew instantly what type of job they were going to perform. The work trailer is so well equipped, organized, and clean that I had trailer envy. Their approach matched the inside of that trailer. They worked well as a team, were very organized, and cleaned up after the work was completed. They paid particular attention to making sure the radon vents were aesthetically pleasing on the outside of our house. They matched our siding color and securely fastened the equipment to our home.   I highly recommend this company.  I have family in the trades and expect quality work for money spent. I received quality work and feel that is the way Tim's other customers also feel. Please take the time to get an estimate from Tim.

Sincerely, Barbara R., Barrington, Il

I wanted to take a quick minute to say thank you for the great service on the installation of our radon mitigation system. And I wanted you to know  how impressed we were with your work ethic and I will be happy to refer you to anyone who could use your services in the future.

 Thanks again,

Timmit Radon did a terrific job installing the radon system at my new home in Kildeer. The work was Professional, on Budget and on Time. Man was I pleased! Great work.

We were pleased with the radon system Timmit installed. They arrived early to start our installation and discussed our options of the best area for the system. They explained how the system worked and what to watch for. They cleaned up perfectly and were finished in half a day. A couple of years later we did notice a slight leak where a pvc pipe had a crack. Tyler came the next day after working a 12-hour shift all night at the firehouse and replaced the pvc pipe. Tim definitely stands behind his company. We have had 2 friends we recommended Timmit to, who also used their service. Timmit has given us peace of mind and our home is much safer now. Thank you for all you do.

We used Timmit Radon Systems when getting ready to put our house on the market.  I contacted Tim and scheduled the mitigation a week after he came out and gave me the estimate. Tim brings his own self-contained trailer that has everything he needs to complete the work. He and his son had everything done in a very short time and it was a very high quality job. Everything matches, the siding, soffit, etc. I had the radon test performed the next week and our levels were brought down to 0.5 pci/l, which is extremely low even with a mitigation system in place. I would highly recommend Tim and his team for your mitigation as they are very professional and you will get a high quality mitigation system installed. We are happy with our results and know that when we sell our home it will be safe for a family to live in.

We evaluated a number of radon mitigation services but chose Timmit because they advertised a guarantee on their work.  Our house posed some challenges in mitigation so this was important to us as a family.  Tim and his team stood by their word every step of the way, even coming back multiple times at their expense to ensure the job was done correctly.  It can be daunting to let strangers into your home but the team at Timmit was not only respectful of our time and privacy but they even got to know our family and we looked forward to their visits.  I'd recommend Timmit to anyone looking for radon mitigation, especially for the peace of mind in knowing they're going to get more than they pay for.  Thank you Timmit!

Tim provided excellent, professional service.  He was very prompt about providing a quote and then installing the system.  All questions were answered and a full report was provided detailing the services.  His pricing was also very reasonable.  I highly recommend him for radon system installations.

Tim was excellent from start to finish.  He is knowledgeable, takes prides in his craftsmanship and is a pleasure to deal with.  We compared other contractors before hiring Tim.  He was not only competitively priced, but used higher grade components than the rest would have." Thanks again, Tim,

Dave K., Mokena, Il


Tim, I just left you a message but also wanted to let you know what a GREAT job Tyler and John did this morning. They were so courteous and so kind. I would like you to tell them for me that it was a job well done and it was a pleasure to have had them in my house. I will certainly pass the word on to neighbors and friends about your company because of the experience I had. 

Susan D., New Lenox, Il

Timmit installed two radon systems for us - one in the house we were selling and one in the house we were buying.   Tim provided a written quote and when it was time for the install they arrived on time, explained the process and completed the work with a high degree of professionalism.  Tim is a personable man who is willing to stop and explain anything you might need clarified and will give you updates on the progress. Timmit Radon Systems does quality work.  I highly recommend their service.

Sincerely, Barbara S., Orland Park, IL


We had a radon abatement system installed by Timmit Radon, and we are very happy with the process and the result. The work was performed on time with no fuss - and at a very reasonable cost. They were highly professional and courteous.  We could ask for nothing else!

Doug E., Serena, IL


I had a contract on my home and the buyer had it tested for radon. It came back positive. I had 6 days to close. Timmit was recommended to us by a friend who had used them also. I checked with my realtor and they also recommended Timmit. It was a quality job with no mess and I was still able to close on time. Go with Timmit, you won't be disappointed.

Mike O., Ottawa, Il

After finding out we needed to remediate, we contacted Timmit Radon and they arrived to review our situation.  Our house was earth-sheltered and there were limited areas to install the system suction.  Tim gave us the best alternative without having to go through the protective seal on the house ... all within their original estimate.  Would give recommendation to use Timmit to anyone.

Fred C., Plainfield, Il

I have referred Timmit’s radon services many times and my customers have never been disappointed. They go above and beyond to please each and every customer.

We had a radon reduction system installed by Timmit Radon Systems in Sept. 2014. The installation went very well and was done on time. The system dropped the radon level from 4.4 pci/l to .7 pci/l. We have not had any problems since the installation. We live in Lockport,Il. and we would definitely recommend using Timmit Radon Systems to our friends and family.

Sincely, Ed F., Lockport, Il

After learning the Radon levels in our home had far exceeded the accepted level, our neighbors referred Timmit Radon Systems to us.  Once we saw first-hand how professionally the radon mitigation system had been installed in their home and how immaculate the Timmit team left their basement, we were sold.  Considering the amount of work and time involved with installing our system, we felt the cost was very reasonable.  We are extremely pleased with the installation they performed in our home and would be more than happy to refer their services to anyone else. Our home is now safe and we are so happy we made that call!  

Ken & Arlene E. - Morris, Il

This is the second radon reduction system I have had Timmit Radon Systems install.  The first system was already installed in my home when I moved in and I was impressed by the overall look.  This is why I chose to have Timmit install a new system in the home we just purchased.  The installers were on time, did an excellent job with the install, and cleaned up after themselves when they were finished.  The job took a day to complete and I was impressed by their attention to detail and again how the system looked when they were finished.   The owner made sure I was completely satisfied by following up with me.  I would highly recommend this company to anyone who is in the market for a Radon Reduction System.   F.Y.I.  I tested my basement with my own testing kit before and after.   After having the radon reduction system installed, it brought my levels of radon down where they should be.  Again, if you are looking for an installer, look no further than Timmit Radon Systems.

Professional and fast service!  Thank you for responding to our request for a radon mitigation system installation.  We were under a time constraint due to a closing on our property.  You came to us as a reference from a reputable real estate agent in the Plainfield, IL area.  You responded to the call quickly and within a few short days you installed the system.  We are thankful for your knowledge and professionalism.  We highly recommend Timmit Radon Systems!
