Should Calvert County Homebuyers Test for Radon?
RETURN TO BLOG
Radon has no smell, color or visible warning sign. The only practical way to know the level in a home is to test.
In Calvert County, a good real estate decision starts with the property, the contract and the buyer or seller’s actual goal. A general rule can be useful, but the details determine the safest strategy.
My approach is simple.
A beautiful finished basement does not tell you whether radon is present. Testing is a small due-diligence step that can answer a health and property question before settlement.
Radon can occur in any Maryland home
The Maryland Department of the Environment says radon is an invisible, odorless radioactive gas that can enter lower levels such as basements. Elevated results have been reported throughout Maryland.
Testing conditions matter
Short-term tests are commonly used during a real estate transaction. Doors and windows must be managed according to the test protocol, and the device should not be moved or disturbed. Use a qualified professional when the result will guide a contract decision.
An elevated result can often be addressed
Radon mitigation systems commonly use active soil depressurization to reduce levels. Buyers should obtain a written proposal, understand electrical and venting needs, and plan for a post-mitigation test.
Keep the inspection strategy organized
Radon is only one part of due diligence. Coordinate it with the general inspection and any specialized reviews, then confirm agreed repairs and systems again during the final walkthrough.
Sellers can test before listing
A pre-listing radon test may give a seller time to address an issue without a contract deadline. It can be considered alongside a broader pre-listing inspection strategy.
The Bottom Line
Radon has no smell, color or visible warning sign. The only practical way to know the level in a home is to test.
Clear facts and careful contract language create better decisions. When the issue matters to your purchase or sale, verify it early and put the agreement in writing.
