After another recommended contractor never bothered calling me back, I requested an online quote…read morefro DuPage Radon Contractors. An excellent exerience from start to finish. Tim the designed called me back the next day and scheduled an appointment to come and assess the housse. Our radon level had been testing between 6 and 8. Tom did a thorough assessment inside and out and created a proposal including a sketch of the installation, including the EXACT cost, which was just under $2000 - very reasonable. I was impressed that they use a large diameter downspout (matching our existing downspout color) extending to the roof line instead of PVC pipe. They also install a housing over the outside fan unit which looks great. They also seal the sump pump with a new lid and seal all the cracks around the perimiter of the basement. The technician Jorge came out two weeks later and performed the entire install. He was amazing! He explained everything, and left it all very clean. Very professional and courteous. I retested the radon level a couple of days later and it tested at .27!!!!!I HIGHLY recommend Dupage Radon Contractors. You will not be disappointed.

The motor in my radon fan was failing and needed replacement. It is less than 3 months outside the…read more5 year warranty. I called DuPage Radon and the very nice woman who answered the phone made it sound like they might cover it, but when she talked to her boss, he said no. Their quote to replace the unit was $400 (they were originally paid approximately $1,200 five years ago) and the soonest they could do it was New Year's Eve. I was able to find the exact same model radon fan at Home Depot for $150 and it literally took me no more than 15 minutes to remove the old unit (and I've never done this before). I'll install the new one when it arrives in the next few days. I don't know about you, but $500 an hour for labor seems excessive to me. Obviously I'm in the wrong profession. Meanwhile, I'm going to remove the DuPage Radon sticker from the cover just out of spite.

They installed radon mitigation equipment with no muss, no fuss, at a reasonable price.

Don't use this service!…read more We were told that the service guy would wear a face mask while in our house Servicing our radon equipment and sump pump that was installed by accurate radon a few years back. We informed the owner, Rich Whiisler, mitigation professional, That I am a high-risk due to my health situation for COVID-19, and inquired if we could put the service off till later due to this fact. Rich said that could be for two years, and they had all the safety measures in place and the service guy would wear a face mask while in the house to protect himself & us, and would only go into the basement areas that had the sump pump and the radon equipment. That is still walking through our entire basement downstairs, which is our carpeted and finished family room. We were told by Rich NOT to go in the basement while the service guy will be servicing the sump pump and radon equipment and to wait three days to wipe down the sump pump room and the radon equipment that may have been touched. Rich also stated the service guy would be using our bathroom to wash his hands with soap and water. I said I did not want the service guy to use our bathroom to wash his hands but to have him bring hand sanitizer instead. Rich stated it is better that he would use water and soap because it gets rid of the germs easier, but he would have him use hand sanitizer instead. What Rich did NOT share with us Is, that the service guy would be taking his face mask off while in the basement servicing the sump pump and the radon equipment. We have an open basement, with no door to close, which is actually our carpeted and finished family room. While we were upstairs, the service guy was servicing our sump pump area and radon equipment in our Open family room basement. We heard him coughing down in our finished family room basement. It was observed, that the service guy had his face mask pulled down under his chin. We called Rich and requested the check to be returned to us. Also, that he never mentioned to us that the service guy would be allowed to take his mask off once he was in the basement. That was never told to us. If Rich would have told us, that the service guy would be allowed to take his face mask off once he was in our finished family room basement, we would have never allowed this service in our home. This was a breach of trust and honesty and I would not recommend anyone using this service. It has put me at a risk even higher for the COVID-19.

That changed a week ago when we opened a wall to track down a leak in the basement and found a former bathroom that had a 5 foot tall pile of construction debris that filled the room. When we shifted the debris out of the building, we uncovered a drain. In the time it took to get a plumber in to plug the drain, we had a few rats enter the building. Exterminators made quick work of them. But they left their mark in the exposed room. Bill was great in getting Amanda out immediately to the site for an estimate. Amanda was very pleasant to work with and did a fantastic job getting that dingy room in the walls clean and sanitized. I greatly appreciate Bio-One and all their help and will be adding them to my service contacts list.

Get the Airthings radon detector and it'll give you short and long term readings. Radon levels change depending on the season and time. Once I realized the levels in my home were rising, I called Professional Radon Systems for a consult. The owner, Eric, came out to my home to determine where the radon mitigation system could go and showed me how and where the pipes would be routed. He sent me a quote later that day by email and I scheduled installation a couple weeks later. The install took less than a couple hours, and the crew that came were very courteous. They ran floor coverings down to my basement so they wouldn't track in or out any debris and they cleaned up after themselves. They showed me what to keep an eye on to make sure the fan was working and provided some documents. This whole experience was very nice. I'm grateful to have a liveable basement now. Thanks Pro Radon Systems!

However, communication was incredibly lacking about vital details like how long our family with two small children would need to be entirely out of the house for the project (not just the rooms in question), despite an in person meeting, signed documentation without those instructions and confirmations of project start date. Lack of clear instructions and communication on a matter so essential to the health and safety of our family caused a last minute scramble to find somewhere safe to live for over 2 weeks and additional worry as parents as they began the work while children were in the home. In response to these concerns, they offered a slight discount (and less than we amount we requested).
