Commercial Construction
Shawn Swallow

Building science

This knowledge of airflow dynamics and diagnostics becomes especially useful in solving complicated mitigation issues influenced by commercial building air flow and building stack effect.

MITIGATION
Mike Murphy
With an engineer’s passion for analyzing information to solve (or avoid) problems, our Lead Project Manager Mike Murphy, has a wealth of radon and VI mitigation experience. As the son of the original founder, (35 years ago) he has been in the industry nearly his entire life. He attends symposiums and conferences to keep abreast of all the latest mitigation techniques and spreads his knowledge throughout the team via the exceptional training program.
What Else Sets Us Apart?
In addition to exceptional training and the experience trifecta, a few other factors set DuPage Radon Contractors apart from competitors in the Chicago suburbs and the Midwest.

Commercial vs. Single-Family Mitigation
Commercial and multi-family mitigation often involves significantly more complexity than single-family homes.
The added complexity can occur in regulation compliance, building dynamics assessment (esp. stack effect and HVAC impacts), paperwork processes, design of the system itself, the installation process, general issue avoidance, and maintenance guidance.
Only a small percentage of the Midwest radon industry are fully skilled in commercial or multi-family mitigation. Selecting a firm with extensive commercial experience can be pivotal in obtaining a problem-free installation of a cost-efficient, effective system.

Our HiSTORY
Founded in 1989 by Calvin Murphy, DuPage Radon Contractors emerged as one of the earliest radon companies in the region. Committed to outstanding customer service and meticulous attention to detail, the business flourished. Calvin’s son, Mike, pitched in from a young age. When Calvin relocated south to join his wife’s family, he entrusted the company to Michael Rumak, who steered it through the challenges of the recession.
After Michael’s retirement, Dan Potter and Shawn Swallow took the helm, upholding the pursuit of excellence. Together, they bring over 60 years of expertise in construction and building science management. Under their leadership, the company has grown steadily, maintaining a strong focus on exceptional customer service. Mike Murphy has since developed into a highly skilled and valued radon mitigator, playing a key role in the team.
Calvin Murphy, now settled downstate, continues to maintain a warm, cooperative connection with DuPage Radon Contractors.
