How Often Should I Have My Home Tested for Radon?

Radon is a colorless, odorless, and tasteless gas that occurs naturally in the environment. It is one of the leading causes of lung cancer, second only to smoking. Since radon can seep into homes through cracks and gaps in the foundation, it’s essential to test your home regularly to ensure radon levels are within safe limits. But how often should you have your home tested for radon? In this blog post, we will explore the ideal frequency of radon testing and the factors that may influence it.

1. Initial Testing

If you have never tested your home for radon before, it’s crucial to conduct an initial radon test as soon as possible. This will provide you with a baseline measurement of radon levels within your home. Considerations such as the age and location of your home, as well as the local geology, may also affect the likelihood of elevated radon levels.

2. Considerations for Radon Testing Frequency

Local Radon Levels: Radon levels can vary significantly from one location to another. Some areas have a higher prevalence of radon due to geological factors, such as the presence of uranium-rich soil or bedrock. It is wise to consult local radon maps or contact your state radon office to determine the radon potential in your area.

Type of Home: The construction type and design of your home can also influence radon levels. For example, homes with basements or crawl spaces are typically more prone to radon infiltration. Additionally, the presence of cracks or gaps in the foundation can allow radon to enter more easily. If your home has undergone significant structural changes or renovations, it may be necessary to retest for radon.

Changes in Occupancy: If there are changes in occupancy within your home, it is recommended to have it tested for radon again. This includes situations such as moving into a new residence, renting out a property, or converting a basement into a living space. Different occupants have varying radon exposure patterns, so it’s crucial to ensure the safety of everyone residing in the home.

3. Recommended Radon Testing Schedule

Short-Term Testing: Short-term radon tests typically range from 2 to 7 days and provide a snapshot of the radon levels. This type of testing is ideal for initial testing or to assess the effectiveness of radon mitigation systems. However, short-term tests may not reflect long-term average radon levels accurately.

Long-Term Testing: Long-term radon tests extend over durations of 90 days to one year, offering a more comprehensive understanding of radon levels in your home. This type of testing is recommended for establishing a more accurate assessment of your radon exposure. If initial tests indicate elevated levels, long-term testing can confirm and help develop appropriate mitigation strategies.

Retesting: The Environmental Protection Agency (EPA) recommends retesting every 2 years as a general guideline. However, considering the factors mentioned earlier, more frequent testing may be necessary. If your initial measurement points towards high radon levels, promptly retest and consult with a professional to address the issue.

4. Continuous Radon Monitoring

Technological advancements have led to the availability of continuous radon monitoring devices. These devices provide real-time updates on radon levels and fluctuations within your home. Continuous monitoring can help you identify patterns and trends, allowing for prompt action if radon levels exceed safe limits. Consider investing in continuous radon monitoring systems for peace of mind, particularly if you are in a high-risk region or have concerns about radon exposure.


Regular radon testing is essential to protect your health and ensure a safe living environment. While the EPA recommends retesting every 2 years, the frequency may vary depending on factors such as local radon levels, home construction, and changes in occupancy. Conduct an initial radon test and consult local radon experts to determine the ideal testing schedule for your specific circumstances. Staying proactive about radon testing will help ensure the long-term safety of you and your loved ones.
