What to record
- Retain actual test results, dates and the test provider's instructions.
- Show any concrete work proposed near an existing mitigation system.
- Do not disturb a system or infer its function from a pipe photograph.
The decision to discuss
Coordinate concrete work with a qualified radon specialist where relevant. EPA advises against relying on sealing alone as a radon reduction method. A concrete repair should describe its own scope without promising an air-quality outcome.
Why the surrounding context matters
EPA does not recommend relying on sealing alone to reduce radon. Keep actual testing and qualified mitigation review separate from a concrete repair inquiry. Work near an existing system should preserve its verified requirements and service access.
