Opening your windows may temporarily lower indoor radon levels, but it is not a reliable solution. Learn why ventilation, air purifiers, crack sealing, and other common approaches do not replace proper radon testing and mitigation.

Every conversation about radon eventually arrives at the same underlying reality: the risk begins in the ground. The geology beneath Michigan — the specific composition of the soil, rock, and glacial deposits that form the foundation of the landscape — is the source of the radon that enters homes across the state. Understanding what Michigan's geology actually looks like, why it produces radon at the levels it does, and why certain parts of the state carry higher risk than ot

Cheap mail-in radon kits can provide a preliminary reading, but certified radon testing offers professional placement, documented protocols, result interpretation, and greater confidence when the results really matter.

Michigan homeowners who are either building a new home or purchasing one built in the past several years sometimes carry an assumption that new construction is automatically safer from a radon perspective than an older home. This assumption is understandable — newer homes are built to higher standards in many respects, with better insulation, more sophisticated HVAC systems, and tighter construction envelopes than their predecessors. But when it comes to radon, the age of a h

Radon does not cause immediate poisoning, but exposure accumulates over years and decades. Learn how concentration, duration, and long-term exposure affect radon-related health risk and why testing your home matters.

Where you place a radon test can significantly affect the accuracy of your results. Learn which level and room to test, how high to place the device, what areas to avoid, and when multiple test locations may be appropriate.

Planning a renovation? Certain home improvement projects can affect radon levels in your home. Learn when to retest after foundation work, basement finishing, HVAC upgrades, and additions.

Ionia County sits at an interesting geographic crossroads in West Michigan. Bordered by Kent County to the west, Montcalm to the north, Clinton and Eaton to the east, and Barry County to the south, it occupies a largely rural stretch of mid-Michigan that rarely makes the top of anyone's list when radon conversations come up in this region. That relative quiet on the topic is part of the problem. Ionia County has radon risk that deserves direct attention, and homeowners in Ion

Ottawa County homes face serious radon risks due to West Michigan geology, older foundations, and growing residential development. Learn why homeowners in Holland, Zeeland, Hudsonville, and nearby communities should take radon testing seriously.

Most homeowners who learn about radon for the first time ask the same question: if it comes from the ground, how does it end up inside my house? The answer has everything to do with the way homes are built and the way air moves through them. Understanding how radon enters is also the first step toward understanding how it can be stopped. Your Home Acts Like a Vacuum The key to understanding radon entry is air pressure. The air inside your home is almost always at a slightly l
