Why Radon Testing is Essential—Even for New Construction
When buying a new home—especially a high-end, custom-built property—it’s easy to assume that modern construction methods provide complete protection from potential hazards. One common misconception is that new builds are immune to radon, a naturally occurring, radioactive gas that can pose serious health risks. However, at Douglas Home Inspections (DHI), we recently encountered a case that proves otherwise.
New Home, Hidden Danger
A recent client purchased a multimillion-dollar home and initially felt that a radon test wasn’t necessary. The house was built on a crawl space that was encapsulated and had spray foam insulation along the walls—features that many assume would block radon intrusion. However, as we always explain to our clients, new construction does not guarantee radon protection. Fortunately, they took our advice and proceeded with a professional radon test.
The Shocking Results
After conducting a 48-hour continuous radon test, the results were alarming. The radon levels reached a maximum of 16.4 pCi/L, with an average level of 11.1 pCi/L—far above the EPA’s action level of 4.0 pCi/L. Exposure to radon at these levels significantly increases the risk of lung cancer, making mitigation a crucial step for the safety of the homeowners.
Why Radon Testing Matters
Radon can seep into homes through the foundation, crawl spaces, and even well water, regardless of the home’s age or construction quality. Factors like soil composition and air pressure differences contribute to radon infiltration. Without testing, homeowners are unaware of the potential dangers lurking in their indoor air.
Key Takeaways:
New homes are not radon-proof – Modern building techniques do not eliminate radon risks.
Encapsulation and spray foam do not block radon – These features may improve energy efficiency but do not prevent radon from entering the home.
High radon levels can be deadly – Long-term exposure to elevated radon increases the risk of lung cancer.
Testing is the only way to know your risk – A professional radon test is the only way to determine radon levels in a home.
