Yes — radon is usually worse in winter in Ohio. Sealed-up homes and the temperature difference between inside and outside combine to pull more radon out of the soil.
The Stack Effect
In winter, warm air rises and escapes through the upper floors of your home, creating a slight vacuum at the basement level. That vacuum draws soil gas — radon included — up through foundation cracks and the slab. The bigger the indoor-outdoor temperature gap, the stronger the pull.
Less Ventilation, Higher Readings
With windows and doors shut tight against Northeast Ohio cold, radon that enters has nowhere to disperse and accumulates indoors. That's why a winter radon test often captures your home's worst-case level — useful information when deciding on mitigation.
