Our mitigation personnel are licensed through the Illinois Emergency Management Agency (I.E.M.A.) Division of Nuclear Safety Radon Program. The I.E.M.A. Division of Nuclear Safety is responsible for protecting Illinois residents from the potentially harmful effects of ionizing radiation.

    Timmit Radon Systems has always taken into consideration the concerns and needs of the present home owner as well as the potential future home owner when designing a radon mitigation system. Whether a basement is unfinished or finished, routing of suction pipe is done in a way that will neither hinder future plans nor ruin an existing finish. The radon system is a permanent part of the home and Timmit Radon's mitigation systems are a reflection of our commitment to excellence. Whether a system's fan is installed on the house exterior or in an attic space, Timmit Radon Systems takes great care to ensure the installation will be aesthetically pleasing and will not be a detriment to the future sale of the home. At Timmit Radon Systems, we believe craftsmanship and aesthetics are as important as system performance.

What are the steps involved in radon mitigation? 

The steps involved in mitigating radon are not rocket science, but rather related to rock science, and are not complicated. In fact, we have figured out how to re-route radon gas from beneath a home's foundation, which is a very straightforward and fairly simple process. Tim took a one week course and passed a test back in 1996 in order to become an EPA licensed mitigator. Timmit Radon Systems has evolved over the past 27 years by making necessary changes to their standard operating procedures which has resulted in unmatched value for our clients. Those changes were due to our experiences & our desire to be the best in the radon industry.

There isn't a radon issue we haven't seen or been able to mitigate successfully in 27 years. If you want to talk to Tim about the steps involved in mitigating your own home, please give us a call. He'd be happy to walk you through the steps so you can decide if it's a DIY project you want to add to your personal list of accomplishments. You may be a DIY extraordinaire that loves the challenge of completing projects and the satisfaction that is gained from doing so. Tim considers himself part of that club, since he's built his own home from the foundation up, a large post frame building, an in-ground pool & founded a very successful radon mitigation business, so he gets the DIY mentality.  If you've done any plumbing, electrical wiring and/or carpentry DIY projects over the years, you could probably mitigate your own home. It'll take you much longer to complete than it would to hire us and it won't look nearly as nice or professional, but that may not be as important to you as it is to us.
