Radon Re-Testing Necessity and Frequency Recommendations

The threats in your home that you can’t pick up through your normal senses are some of the most dangerous, and radon is a good example. This harmful contaminant can’t be seen or smelled, but high levels can lead to major health risks — and because radon levels can change with time, you should be testing for it on a somewhat regular basis.

At Absolute Radon Safety, we’re proud to offer a variety of high-quality radon testing services, including both short-term and continuous monitoring radon testing. We’re also here to provide expertise, particularly to homeowners who may think they’re permanently in the clear if their radon levels were tested in the past and were low — there are several important reasons why re-testing for radon periodically is important. Let’s dive into what may impact changing radon levels over time, plus how often the EPA recommends you have your radon levels re-tested.

Factors in Changing Radon Levels Over Time

Radon comes from uranium deposits in the ground, seeping into homes through their foundations. There are a few factors that may lead to changing radon levels over time, including:

  • Time of year: Radon levels tend to be higher in the colder months of November through March.
  • Type of construction: Homes with basements are more likely to have elevated radon levels than homes built on a crawl space or a slab.
  • Changes in the home: Sometimes, renovations can impact airflow and ventilation, which could lead to higher radon levels over time. The EPA recommends giving your indoor air quality a check-up after any major renovation work is completed.
  • Foundation changes: One particular type of change that may lead to heightened radon levels is any damage or major changes to your home’s foundation.

EPA Recommended Testing Frequency

Due to the above facts about how radon levels can change in your home, the EPA recommends having your home tested for radon every two years — even if you’ve had your home tested before with negative results. If you’re planning on selling your home, it’s very important to note that most states require an “as is” radon test, meaning your home must be tested even if you don’t plan on making any major changes to the structure.

And even if you aren’t selling, this testing frequency is valuable for maintaining health and comfort. Did you know, for instance, that radon is the top cause of lung cancer outside of cigarette smoking? Over 20,000 people die every year just from the harmful effects of radon — so if you have the ability to protect yourself from this threat, why wouldn’t you take it?
