Best Radon Testing in Miami, FL

How much does radon testing cost in Florida?

Professional radon testing typically costs $175 to $350. Short-term tests (48-96 hours) are used for real estate transactions. Long-term tests (90+ days) provide the most accurate annual average. The Florida Department of Health recommends professional testing for real estate closings, though Florida-approved DIY kits ($20-$40) are available at hardware stores if you follow chain-of-custody instructions.

Why is radon especially concerning in Florida?

Florida has varying radon levels depending on geology and porosity of underlying rock. Hillsborough, Polk, and several North-Central counties often show higher averages, but Miami-Dade, Broward, Palm Beach, Hillsborough, and Orange counties all report elevated homes, so geology alone does not rule risk out. The Florida Department of Health treats indoor radon as a preventable public health issue and maintains county-level radon data.

Are radon testers required to be certified in Florida?

Florida Department of Health lists Florida-certified measurement specialists; NRPP and NRSB credentials are also widely accepted. For real estate transactions, use a Florida-certified or NRPP/NRSB-listed professional who follows EPA closed-house conditions so results hold up with insurers and buyers.

What happens if my Florida home has high radon levels?

If radon levels exceed 4 pCi/L, the EPA and Florida Department of Health recommend installing a radon mitigation system sized for Florida's slab-on-grade and stem-wall construction. Active soil depressurization is the most common fix and typically costs $1,000 to $2,500. Hire a Florida Department of Health-certified mitigation specialist; properly installed systems often reduce levels by 90% or more.

When should I test for radon in my Florida home?

The Florida Department of Health recommends testing all homes, especially in mapped higher-potential areas and after hurricanes that shift slabs or foundations. Test during real estate transactions, after major renovations affecting the foundation, or if you have never tested. Follow EPA closed-building conditions (typically November through March in Florida) for the most representative short-term tests, then re-test every two years or after major structural changes.
