Why is radon especially concerning in New York?

New York has varying radon levels depending on geology. Kings, Queens, New York (Manhattan), Suffolk, and Bronx counties include many homes where bedrock, fill, and foundation details can produce elevated radon. Even other areas of the state have measurable radon. NYSDOH considers it a public health issue and publishes county-level radon data.

Are radon testers required to be certified in New York?

Certification requirements vary by state. NYSDOH and professional organizations like the National Radon Proficiency Program (NRPP) or National Radon Safety Board (NRSB) recommend certified testers. For real estate transactions, use a certified professional to ensure legally defensible results.

What happens if my New York home has high radon levels?

If radon levels exceed 4 pCi/L, the EPA and NYSDOH recommend installing a radon mitigation system. Sub-slab depressurization is the most effective method and typically costs $1,000 to $2,000. State-certified contractors can perform mitigation. Mitigation reduces levels by up to 99%.

When should I test for radon in my New York home?

NYSDOH recommends testing all homes, especially in high-risk areas. Test when buying or selling, after major renovations affecting the foundation, or if you have never tested. Testing during cooler months (November through March) with windows closed provides the most representative results. Re-test every 2 years or after major changes to the home.
