Quick takeaway: A short-term radon test is a simple way to confirm conditions before closing.

What to Expect

• Real estate / due diligence: short-term testing is typically performed over a defined test period under standard “closed-house” conditions (details provided at scheduling).
• Clear results: you’ll receive a documented reading (pCi/L) with practical guidance on what the number means.
• Flexible scheduling: add radon testing to a home inspection or schedule it as a standalone service.

Examples of other conditions commonly observed during home inspections can be found in our inspection photo galleries.

Understanding Radon Test Results

• At or below 2.0 pCi/L: Low level
• Between 2.0 and 4.0 pCi/L: Elevated; mitigation may be considered
• At or above 4.0 pCi/L: Action recommended per EPA guidance

Because radon levels can fluctuate due to weather conditions, seasonal changes, and home use, it is a good idea to retest at least every two years and after significant home changes (such as renovations, foundation work, or HVAC/ventilation modifications).

Radon Testing FAQs

Do you offer radon testing in Johns Creek and Metro Atlanta?
Yes. Inspect-More provides professional radon testing services in Johns Creek and throughout the Metro Atlanta area. Radon testing may be scheduled as a standalone service or added to a home inspection.

What is radon, and why does it matter?
Radon is a naturally occurring radioactive gas that can enter homes through the soil. It is colorless and odorless, and long-term exposure to elevated radon levels is a known health concern. Testing is the only way to determine a home’s radon level.

What radon level is considered high?
The Environmental Protection Agency (EPA) recommends taking action when radon levels are 4.0 picocuries per liter (pCi/L) or higher. The EPA also notes that levels between 2.0 and 4.0 pCi/L may warrant consideration of mitigation.

How is radon testing performed?
Radon testing is conducted using industry-accepted testing methods and EPA-recommended protocols. The test measures radon levels under the conditions present during the testing period and provides a clear, documented result.

How long does a radon test take?
Most residential radon tests are conducted over a defined testing period in accordance with standard protocols. Specific timing and setup requirements will be explained at the time of scheduling so you know what to expect.

Do radon levels change over time?
Yes. Radon levels can fluctuate due to weather conditions, seasonal changes, ventilation patterns, and other environmental factors. A radon test represents a snapshot of conditions during the testing period.

How often should radon be retested?
The EPA recommends retesting at least every two years and after significant changes to the home, such as renovations, foundation work, or HVAC and ventilation modifications. Homes with radon mitigation systems should also be periodically retested to confirm continued performance.

If radon levels are elevated, what are the next steps?
If elevated radon levels are reported, a qualified radon mitigation professional can evaluate the home and recommend corrective measures. Inspect-More provides clear results and EPA-based guidance to help you understand available options.
