Radon is colorless, odorless, and the second leading cause of lung cancer in the U.S. Testing is the only way to know if your home is safe.
Radon is a naturally occurring radioactive gas that forms from the decay of uranium in soil and rock. It seeps into homes through foundation cracks, gaps around pipes, and other openings — and because it’s completely odorless, colorless, and tasteless, you will never know it’s there without a test.
Radon is the second leading cause of lung cancer in the United States, responsible for approximately 21,000 deaths per year according to the EPA. The good news: if elevated radon is found, mitigation systems are effective, reliable, and typically installed in one to two days.
Many buyers assume Arizona’s desert climate means no radon risk. That’s incorrect. The EPA has identified elevated radon levels in homes throughout Maricopa County. Gilbert, Chandler, Mesa, and Queen Creek are not exempt. The only way to know the radon level in a specific home is to test it.
Radon is not a theoretical risk. These are EPA-published figures that apply to homes across the country — including Gilbert and the East Valley.
Book online 24/7 or call (602) 581-5678. Bundling your radon test with your home inspection means Kelly places the test device during the same visit. One appointment, complete information.
Kelly places an EPA-compliant radon test device in the lowest livable area of the home — typically a basement, ground floor bedroom, or lowest level room. The device must remain undisturbed during the testing period with windows and doors closed as required by EPA protocol.
After the required testing period, Kelly retrieves the device and sends it to a certified independent laboratory for analysis. The lab measures the radon concentration in picocuries per liter (pCi/L).
You receive your lab results within 48 hours. If the result is below the EPA action level of 4 pCi/L, you can proceed with confidence. If it is at or above 4 pCi/L, your written report will include information on the next steps and mitigation options.
If elevated radon is found, Kelly can refer you to qualified radon mitigation contractors in the Gilbert and East Valley area. Radon mitigation systems are highly effective, typically installed in one to two days, and can reduce radon levels by up to 99%. This is often a seller negotiation item before closing.
A high radon result is not a reason to walk away from a home — it’s a reason to negotiate. Radon mitigation systems are effective, affordable, and can bring radon levels down to safe concentrations. You can use the test result to request that the seller install a mitigation system before closing, negotiate a price reduction to cover installation, or request a seller credit. Kelly’s written report documents everything you need to have that conversation with confidence.

Is radon a problem in Gilbert, AZ?
Yes. Arizona is not immune to radon. The EPA has identified elevated radon levels in homes across Maricopa County, including Gilbert, Chandler, Mesa, and Queen Creek. The only way to know the radon level in a specific home is to test — radon is colorless, odorless, and tasteless, making it completely undetectable without testing equipment.
What is radon and why is it dangerous?
Radon is a naturally occurring radioactive gas that forms from the decay of uranium in soil and rock. It seeps into homes through foundation cracks, gaps around pipes, and other openings. Radon is the second leading cause of lung cancer in the United States, responsible for approximately 21,000 deaths per year according to the EPA. It is odorless, colorless, and tasteless — you cannot detect it without a test.
What is the EPA action level for radon?
The EPA recommends taking action to reduce radon levels if a test result shows 4 picocuries per liter (pCi/L) or higher. The EPA also recommends considering mitigation for levels between 2 and 4 pCi/L. Radon mitigation systems are effective, reliable, and typically installed in one to two days.
How long does radon testing take?
Leading Edge Plus Inspections uses EPA-compliant short-term radon testing. The test device is placed in the home for the required period, then sent to a certified laboratory. Results are typically available within 48 hours. Testing can be bundled with your standard home inspection in a single visit.
Can I bundle radon testing with my home inspection?
Yes — bundling radon testing with your home inspection is the most efficient approach. Kelly places the radon test device during the home inspection visit, and results come back from the lab within 48 hours. One visit, complete information.
What if my radon test comes back high?
A high result is not a reason to walk away — it’s a reason to negotiate. Radon mitigation systems are effective, affordable, and can reduce radon levels by up to 99%. You can request that the seller install a mitigation system before closing, negotiate a price reduction, or request a seller credit. Kelly can provide referrals to qualified mitigation contractors in the Gilbert area.
All three Plus services can be scheduled in a single visit with your home inspection. One inspector, one day, complete picture.
