Radon Reduction Tips
Testing comes first. For elevated levels, active soil depressurization is a common professional approach, while sealing is generally a supporting step rather than a guaranteed standalone solution.
Start with evidence
Confirm test quality and use a property-specific assessment. Compare written system designs instead of choosing solely by price.
Support system performance
Keep fans operating, check indicators, maintain sump covers and membranes, retain documents, and retest after major building changes or as recommended.
Avoid unsupported shortcuts
Ventilation changes can affect readings but may be temporary, energy-intensive, or create other building problems. Do not promise a specific reduction without testing.
What to do next
Use the cost estimator for planning or search for professionals whose recorded service area matches your ZIP code.
