Radon Testing
Knowledge Is Power: Know the Radon Levels in Your Home.
A continuous radon monitor test can help you understand the air quality in your home and identify invisible dangers before they affect your health. The EPA estimates that one in every fifteen homes in the U.S. has elevated radon levels — and Delaware is no exception.
At Quality Home Inspections, we offer professional radon testing in Wilmington, DE, and surrounding areas to give homeowners and buyers peace of mind. Testing is simple, fast, and essential whether you’re purchasing, selling, or simply maintaining a safe home environment.
Why Radon Testing Is Important — Especially Before You Purchase
Radon is a colorless, odorless gas produced by the natural breakdown of uranium in soil, rock, and water. As it moves upward through the ground, it can seep into homes through foundation cracks, gaps, or sump pumps.
Because you can’t see or smell radon, testing is the only way to detect it.
Homebuyers should always request a radon test before finalizing a purchase. Elevated levels can often be negotiated for mitigation, saving you money and ensuring a healthier home environment from day one.

What Are the Dangers of Radon?
According to the EPA, radon exposure is the second leading cause of lung cancer after smoking. It becomes hazardous when trapped indoors, especially in basements and lower-level areas with poor ventilation.
Even small amounts of radon over time can pose significant health risks. The longer you’re exposed, the greater your chances of developing lung damage. Testing allows early detection and mitigation before problems arise.
How Does Radon Enter the Home?
Radon gas seeps through cracks in foundations, sump pump openings, or gaps around pipes and drains. Once inside, it can accumulate to dangerous levels if airflow is limited.
Older homes, homes with basements, and homes built over granite or shale-based soil are especially vulnerable.
Our team uses EPA-approved continuous radon monitors to record radon levels over a 48-hour period, providing a reliable snapshot of your home’s indoor air quality.
