What makes a house more likely to have radon?

Understand Why Some Homes Face Higher Radon Levels

Many homeowners wonder what makes a house more likely to have radon in the first place. Radon is an odorless, radioactive gas that naturally forms from the decay of uranium found in soil and rock. Certain geological conditions can make radon more prevalent in specific areas, allowing it to seep through cracks and openings in a home's foundation. Factors such as the type of soil beneath your property, how well your basement or crawl space is sealed, and the overall construction style of your house can all influence radon levels.

Houses with unfinished basements, gaps around service penetrations, or compromised concrete slabs often have greater potential for radon infiltration. Negative air pressure within the house, which can be caused by exhaust fans, heating systems, or leaky ductwork, can also draw radon indoors from the soil more easily. Additionally, older homes may have settled foundations and cracks, creating new entry points for radon. The risk isn't exclusive to older properties, however, as even newly built homes can have insufficiently sealed structures.

The first step to understanding whether your home is at risk is to perform radon testing. Various do-it-yourself test kits can be placed in the lowest livable areas of your home to measure radon levels over a set period of time. Professional radon testing services may offer more in-depth analysis, ensuring a clear picture of your property's condition. If high concentrations of radon are detected, mitigation measures such as sealing cracks, installing vent pipes, or upgrading ventilation systems can help reduce indoor radon levels.

Beyond controlling radon infiltration, it's essential to maintain proactive home upkeep, including checking for foundation damage and ensuring proper airflow.
