Summer Radon Risks: Why Mitigation Matters in Warm Weather

June 30, 2025      

Most people associate radon issues with cold weather and closed-up homes in the winter—but did you know summer can also increase radon levels in many homes? At Radon Guys, we specialize in keeping homes safe from radon year-round, and that includes helping homeowners understand why mitigation matters just as much during the summer.

Here’s why you shouldn’t let your guard down just because it’s hot outside.

How Summer Weather Can Increase Radon Entry

Radon is an odorless, invisible gas that enters your home from the ground. While winter is known for trapping radon indoors, summer conditions can also create the perfect environment for elevated radon levels—especially in homes without mitigation systems.

Air Conditioning and Negative Pressure

When your AC is running, it creates slight negative pressure inside your home. This pulls air (and radon gas) up from the soil and into lower levels like basements or crawl spaces.

Closed Windows and Less Airflow

Hot weather often means your windows stay closed for weeks at a time. Without fresh airflow, any radon that enters your home can build up and stay trapped—especially in well-insulated, tightly sealed houses.

Summer Storms and Heavy Rain

Storm systems and pressure changes can push radon into your foundation. Saturated soil from heavy rain may also block natural ventilation pathways for radon in the ground, redirecting it into your home instead.

Why Mitigation Isn’t Just for Winter

Radon doesn’t go away when the seasons change. Without a radon mitigation system, your home can be vulnerable to seasonal spikes in radon—especially if you spend more time indoors during the hottest parts of the day.

Whether it’s a finished basement, a home office, or just keeping cool with the AC running, your home needs year-round radon protection. A professionally installed system works 24/7, maintaining low radon levels regardless of outside temperature or weather.
