Do You Really Need a Radon Test in Montgomery County, MD?

If you own or plan to sell a home in Montgomery County, MD, radon testing is more than just a suggestion — in many cases, it’s a requirement.

In 2016, Montgomery County passed a law requiring radon testing prior to the sale of most single-family homes. But even beyond real estate transactions, radon testing is a smart and essential part of protecting your family’s health.

Why It Matters in Montgomery County

This area is considered moderate to high risk for radon gas by the EPA. Radon is colorless and odorless, and it’s the second leading cause of lung cancer in the U.S. — right after smoking.

Testing is the only way to know if your home is safe. Even if your home passed a test in the past, environmental changes, new construction nearby, or foundation settling can cause radon levels to rise.

Who Should Test?

• Homeowners who haven’t tested in 2+ years

• Sellers preparing for listing

• Buyers doing due diligence

• Renters living in basements or garden-level units

What About Newer Homes?

Even new builds in the DC Metro area can test high. Radon isn’t selective — it comes up through the soil beneath any structure.

Pro Tip: Most real estate agents in this area are now familiar with radon testing requirements. Having a valid test ready before you list can save time, negotiations, and surprises.
