Breathe Easier with Certified Radon Testing
At DB Air Quality, we specialize in certified radon testing for homeowners across Portland, Falmouth, and Southern Maine. Radon is a colorless, odorless radioactive gas that can seep into your home from the ground—and long-term exposure can pose serious health risks, including lung cancer.
That’s why our local team is here to give you peace of mind with fast, reliable testing. Whether you're buying a home, selling one, or simply want to protect your family, we’re ready to help.
Who Needs Radon Testing?
Radon testing isn’t just for home buyers—it’s essential for anyone who wants to ensure their indoor air quality is safe. You need radon testing and mitigation if you:
Own a home and rent it out
Own a home and occupy it yourself
Are a realtor helping clients buy or sell
Are a contractor remodeling or building new homes
Even if your neighbor’s home tested low for radon, yours could have elevated levels. Testing is the only way to be sure your home is safe.
Why Radon Testing Is So Important in Maine
Maine is one of the highest-risk states for elevated radon levels in homes. According to the EPA, any radon level above 4.0 pCi/L should be addressed quickly.
Common symptoms of long-term radon exposure include:
- Persistent coughing or wheezing
- Shortness of breath
- Chest discomfort
- Fatigue or headaches
But the real danger is what you don’t feel. Radon exposure is the second leading cause of lung cancer in the U.S.—and the only way to know your risk is to test.

What to Expect During Your Radon Test
We use the industry gold standard: the Continuous Radon Monitor (CRM) test. It’s fast, non-invasive, and incredibly accurate.
3-Step Radon Testing Method
Step 1: Schedule Your Test
Call us at 207-615-1507, and we’ll find a convenient time to install the CRM monitor in your home’s lowest livable level (usually a basement or first floor).
Step 2 – 48-Hour Testing Period
Our CRM device collects air samples over a 48- to 72-hour window, tracking fluctuations and ensuring reliable readings under closed-house conditions.
Step 3: Same-Day Results
Once we retrieve the monitor, we’ll analyze your results and explain them clearly. If levels are elevated, we’ll walk you through next steps for radon mitigation.
