Fully
Licensed

In Illinois, radon mitigation activities are heavily regulated, and challenging training and testing is required to obtain a state radon mitigation license. Every DuPage Radon Contractors installation team has at least one licensed installer on the job, and the owner of the company has a specific professional license as well. All licensees at our company complete continuing education and training as well. Click here to be sure a company has an Illinois license.

Fully
Insured

DuPage Radon Contractors carries and has in effect at all times at least two million dollars in aggregate commercial liability coverage, which covers all company activities, including vehicles.

Highly
Trained

We have a team that brings more to the job than just the required training. Our team's training includes new and remodeling building trades, building envelope analysis and building air flow dynamics. We're always growing our knowledge through continuing radon science and radon mitigation training that exceeds state requirements.

Workers
Compensation

All our radon specialists are covered if they hurt themselves on your property. Not all companies take this important and expensive step. Click here to check if a company has Workers Comp Insurance.

Full-time Employees

We don't employ part-timers or sub-contractors to get our jobs done. Hiring full-time employees gives us more control over our team's actions and instills loyalty. Our full-time radon specialists quickly gain on-the-job experience in a shorter amount of time than part-time employees would. With our training program and large amount of work, our new employees don’t stay “green” for long. Our installers often see more jobs in a month than some part-timers do in 6 months.

Locally
Owned and Operated

DuPage Radon Contractors has been family owned since inception. We're not a national chain with out of state ownership. If a major decision needs to be made, we can make it quickly. Need to talk to our owners, Dan Potter (pictured) or Shawn Swallow? Just ask.

    Highly trained, licensed, insured, and background checked, the DuPage Radon Contractors’ employees are also friendly and adept at explaining our systems.





  • History

    Started in 1989 by Calvin Murphy, DuPage Radon Contractors was one of the first area radon firms. Dedicated to great customer service and attention to detail, it thrived. Calvin’s son, Mike Murphy, helped Calvin out from childhood. When Calvin decided to move south to be closer to his wife’s family, he handed the reins over to Michael Rumak.

    Michael Rumak, aided by wife Carol, continued the drive towards excellence and kept the company viable during the big recession.

    Upon Michael’s retirement, the leadership baton was passed to Dan Potter and Shawn Swallow. They have a combined 60+ years in the construction and building science industry. They have steadily expanded the business with their drive to provide exceptional professionalism in all parts of the customer experience.

    Mike Murphy has become one of the most respected mitigators in the Midwest and holds a pivotal position on the team.

    Calvin Murphy still performs mitigation service downstate, and keeps a collaborative and professional relationship with the DuPage Radon Contractors team.
