Radon Testing During a Home Inspection

Radon is a naturally occurring radioactive gas that forms in the soil and can enter homes through cracks, penetrations, and other openings in the foundation. Because radon is colorless, odorless, and tasteless, elevated levels cannot be detected without specialized testing equipment.

Homes of any age, size, or construction type can have elevated radon levels. Even neighboring homes may produce significantly different test results.

A radon test measures the concentration of radon present within the home during the testing period and provides valuable information about the indoor environment at the time of testing.

Why Consider Radon Testing?

Mold growth often develops when moisture is present for an extended period. Roof leaks, plumbing leaks, inadequate ventilation, high humidity, and previous water intrusion can all create conditions that allow mold to grow.

Many mold concerns are hidden behind walls, beneath flooring, inside attics, or within crawlspaces. In some cases, elevated mold levels may be present even when no visible mold is observed during the inspection.

Mold testing may be worth considering if:

• The home has a history of water damage

• The history of the home is unknown

• Musty odors are present

• Visible staining or discoloration is observed

• The property has been vacant for an extended period

• Recent plumbing or roof leaks have occurred

• Occupants have experienced indoor air quality concerns

• Additional peace of mind is desired before purchasing

What Is Included With Radon Testing?

A continuous radon monitor is placed within the home and remains in place throughout the testing period, typically 48 to 72 hours. During this time, the monitor records radon levels and environmental conditions to help verify testing integrity.

The testing process follows established protocols designed to help obtain representative results during the testing period.

Clients receive a written report summarizing the test results and average radon concentration measured during the test.

Frequently Asked Questions

Is radon common in Utah?

Yes. Elevated radon levels have been identified throughout Utah. While some areas are more prone to elevated levels than others, any home can have a radon issue regardless of age, location, or construction type.

How long does the test take?

Most real estate radon tests are conducted over a period of 48 to 72 hours. The monitor continuously records radon levels throughout the testing period.

What if the results are elevated?

If elevated radon levels are identified, a radon mitigation specialist can evaluate the property and discuss available mitigation options. Many homes can be effectively mitigated through the installation of a radon reduction system.

Can a home have a mitigation system and still need testing?

Yes. A mitigation system should reduce radon levels, but testing is the only way to verify that the system is operating effectively and maintaining acceptable radon concentrations.
