When Should You Retest for Radon?
When Should You Retest for Radon?
Radon levels can change over time, so a single old result may not reflect current indoor conditions. Retesting helps homeowners, buyers, sellers, and property managers make informed decisions.
Common Times to Retest
- Before buying a home
- Before listing a home for sale
- After finishing a basement or lower level
- After major renovations or foundation work
- After installing or repairing a radon mitigation system
- After changes to HVAC, ventilation, or occupancy patterns
- If the last radon test is old or unavailable
Why Retesting Matters
Radon entry can be affected by soil conditions, foundation openings, ventilation, weather patterns, and building changes. Testing your specific property is the only way to know the current radon level.
