Radon Inspections

Radon gas is a naturally occurring radioactive gas that you can’t see or smell — but it can pose a serious health risk if it accumulates in your home over safe levels. A professional radon inspection identifies elevated radon concentrations so you can protect your family and investment.

Why Radon Inspections Matter

Radon is the second leading cause of lung cancer in the United States, and the only way to know if it’s present in your home is through testing. Even newer homes with tight construction can trap radon at harmful levels — especially in basements and lower living spaces. Detecting and mitigating radon early gives you peace of mind and ensures a healthier living environment for you and your loved ones.

What a Radon Inspection Covers

During a radon inspection, our certified inspectors:

• Use specialized testing equipment designed to measure radon levels accurately over a defined period

• Place monitors in key locations of the home (typically lower-level living spaces)

• Collect and analyze data to determine if levels exceed EPA recommended action thresholds

• Provide a clear, written report with results and next steps if elevated radon is found

This professional assessment gives you the information you need to make confident decisions about mitigation and safety planning.

When to Schedule a Radon Inspection

Radon inspections are recommended:

• During the home buying or selling process

• When your home has a basement or crawl space

• If previous testing showed elevated levels

• If you’ve lived in the home for several years without testing

Because radon levels can vary over time and with changes in weather or ventilation, it’s smart to test whenever there’s a transition in ownership or occupancy.

Radon Inspection FAQs

What is radon and why is it dangerous?

Radon is a naturally occurring radioactive gas that forms from the breakdown of uranium in soil and rock. It can enter a home through cracks in foundations, sump pits, and other openings. Long-term exposure to elevated radon levels is a leading cause of lung cancer in non-smokers.

How do I know if my home has radon?

There’s no way to see or smell radon. The only way to know if radon is present in your home is through professional testing using approved monitoring equipment.

How is a radon inspection performed?

A radon inspection involves placing a testing device in the lowest livable area of the home for a set period of time. The monitor collects data to measure average radon levels, which are then analyzed and reported.

How long does radon testing take?

Most radon tests are conducted over a minimum of 48 hours to provide accurate results. After the testing period is complete, results are reviewed and included in a detailed report.

What radon level is considered unsafe?

The EPA recommends action if radon levels are at or above 4.0 picocuries per liter (pCi/L). Even levels below this threshold may still pose some risk, and mitigation may be recommended depending on the situation.

Can radon levels change over time?

Yes. Radon levels can fluctuate based on weather conditions, seasonal changes, and how a home is ventilated. That’s why radon testing is recommended during real estate transactions and periodically over time.

What happens if high radon levels are found?

If elevated radon levels are detected, we’ll explain the results and recommend next steps. This typically involves consulting a licensed radon mitigation professional to install a system designed to reduce radon levels.

Do new homes need radon testing?

Yes. Newer homes can still have elevated radon levels, especially due to tight construction that limits natural ventilation. Testing is recommended regardless of the age of the home.
