Radon Testing in Michigan

Elevate Radon Defense provides radon testing for homes, businesses, real estate transactions, and properties with existing mitigation systems throughout Macomb, Oakland, Washtenaw, and Wayne counties.

Know What Is Happening Inside Your Property

Radon is a naturally occurring radioactive gas that can enter a building through openings between the structure and the soil. Its presence is not limited to older homes, basements, or one construction style. Newer properties, slab foundations, crawl-space buildings, and commercial spaces can also have elevated readings.

A neighboring property may have a different result because radon levels can vary from one building to another. The only way to understand the conditions inside your property is to measure the air with a device designed to detect radon.

Long-term radon exposure increases the risk of lung cancer. The EPA recommends taking action when a home measures 4 pCi/L or higher and considering action when results fall between 2 and 4 pCi/L.

Our team follows a clear process from device placement through result review. We explain the testing conditions, help you understand the measured level, and discuss practical next steps without unnecessary technical language.

Radon Testing for Homes and Businesses

Elevated radon can be present in many types of buildings. Testing provides current information that homeowners, buyers, sellers, businesses, and property managers can use when making decisions about a property.

You should consider scheduling a test when:

• A property has never been tested
• You are buying or selling a home
• A previous result is more than two years old
• Major renovations have changed the building
• A basement is used as living space
• A mitigation system is already installed
• You want to establish a current radon level

Michigan EGLE recommends testing homes every two years, including homes with active or passive mitigation systems. Buildings settle, foundation conditions can change, and radon measurements may differ over time.

What to Expect During Professional Radon Testing

Useful results depend on more than placing a device in a room. Device location, testing duration, building conditions, and equipment handling can all affect the measurement.

Property and Testing Review

We begin by learning why the test is needed and whether the property has previous results or an existing system. A real estate test may involve different timing and access concerns than routine testing requested by a current homeowner or business.

Understanding the purpose of the measurement helps our team plan the appointment and explain what you should expect.

Appropriate Device Placement

The testing device is placed at an appropriate level and location based on the building and the purpose of the measurement. We explain where the device will be placed and why the area was selected.

Testing is generally performed in the lowest level that is regularly occupied or could be used as living space. Devices should be placed away from locations where drafts, moisture, heat, or frequent movement may interfere with the measurement.

Testing Condition Instructions

Certain building conditions should remain consistent during a short-term test. We explain how occupants and property representatives can avoid interfering with the measurement.

Instructions may include keeping exterior doors and windows closed except for normal entry and exit, avoiding movement of the device, and limiting the use of equipment that brings large amounts of outdoor air into the building.

Clear Result Review

After the measurement period, we explain the result in plain language. We discuss how it compares with current action guidance and whether follow-up testing, continued monitoring, mitigation, or system service should be considered.

You receive more than a number. Our goal is to help you understand what was measured, why the result matters, and what options may be appropriate for the property.

Understanding Your Radon Test Result

Results are commonly reported in picocuries per liter of air, written as pCi/L. The number represents the radon concentration measured during the testing period.

A reading below 4 pCi/L should not be described as “radon-free” or completely safe. The EPA states that there is no known safe level of radon exposure. Lower readings generally represent lower risk, and property owners may still consider reducing radon when results fall between 2 and 4 pCi/L.

When a reading is elevated, the next step depends on the type of test, the reason for testing, and the property. We may discuss confirmation testing or a mitigation evaluation. If the building already has a system, an elevated result may indicate that an inspection or repair should be considered.

Our role is to provide clear information rather than pressure you into a decision. We explain the result, answer questions, and outline practical options.

Radon Testing for Real Estate Transactions

A radon test can provide important information during a property purchase or sale. Buyers may want to understand the measured level before taking ownership, while sellers may need current documentation during the transaction.

Short-term screening measurements generally require a minimum of 48 hours. Testing conditions must be maintained throughout the measurement period, so it is important to coordinate access and timing early.

Elevate Radon Defense works with buyers, sellers, real estate agents, and property representatives to make the process clear. We explain the testing requirements and provide results that can support an informed conversation about the property.

Testing After Mitigation or System Repair

A running mitigation fan does not confirm the indoor radon level. Testing is needed to measure how the property and system are performing.

Post-mitigation testing helps determine whether a new system has reduced the measured level. Testing may also be useful after fan replacement, pipe repair, foundation work, major remodeling, or other changes to the building.

Continued retesting can identify changes that may not be visible during a system inspection. This is especially important when lower-level rooms are regularly used as bedrooms, offices, family rooms, or other occupied spaces.
