Frequently Asked Questions
How much does radon testing cost in New Jersey?
Professional radon testing in New Jersey 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. NJ DEP recommends professional testing over DIY kits for real estate transactions, though DIY kits ($20-$40) are available at hardware stores.
Why is radon especially concerning in New Jersey?
New Jersey has significantly elevated radon levels, particularly in the Highlands region covering Hunterdon, Morris, Somerset, Sussex, and Warren counties -- some of the highest in the nation. The granite and gneiss bedrock in these areas is naturally high in uranium, which decays to produce radon gas. Even southern NJ's Coastal Plain counties have measurable radon. NJ DEP publishes county-level radon data and considers it a serious public health issue.
Are radon testers required to be certified in New Jersey?
New Jersey does not have a mandatory state certification requirement for radon testers, but the NJ DEP strongly recommends using testers certified by the National Radon Proficiency Program (NRPP) or National Radon Safety Board (NRSB). For real estate transactions, use a certified professional to ensure legally defensible results.
What happens if my New Jersey home has high radon levels?
If radon levels exceed 4 pCi/L, the EPA and NJ DEP recommend installing a radon mitigation system. Sub-slab depressurization is the most effective method and typically costs $1,000 to $2,000 in New Jersey -- slightly higher than the national average. NJ DEP has a Radon Contractor Certification Program for mitigation contractors. Mitigation reduces levels by up to 99%.
When should I test for radon in my New Jersey home?
NJ DEP recommends testing all New Jersey homes, especially in the Highlands counties. 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.
