Radon Mitigation Cost in Orange, NY

The EPA classifies Orange as Zone 1 because the predicted average indoor radon screening level exceeds 4 pCi/L. This is primarily due to the geological composition of the area — certain rock types (granite, shale, phosphate) naturally contain higher concentrations of uranium, which decays into radon gas.

In Zone 1 counties like Orange, a significant percentage of homes test above the EPA's 4.0 pCi/L action level. While every home is different, the probability is substantially higher than the national average. Testing is essential before making any purchase decision.

Radon mitigation is not federally mandated. However, the EPA strongly recommends mitigation when levels exceed 4.0 pCi/L. In NY, New York does not have a state-mandated radon disclosure requirement, but sellers must complete the Property Condition Disclosure Statement, and failing to disclose known issues can create legal liability.. Many mortgage lenders and home insurers in Zone 1 areas require or encourage radon testing.

No. NY does not have a specific radon disclosure or testing mandate for real estate transactions. However, the EPA recommends testing all homes, and buyers in Orange should request a radon test during the inspection period.

Absolutely. The absence of a state mandate does not mean absence of risk. Radon is a health hazard regardless of legal requirements. In Orange (Zone 1), testing costs $15-$30 and takes 2-7 days — a small investment compared to the health risks of long-term exposure.

Based on local labor rates and material costs, radon mitigation in Orange typically costs between $1025 and $1813, with an average of $1419. The final cost depends on your foundation type (basement, crawl space, or slab) and the complexity of the installation.

This is negotiable. In most real estate transactions, the buyer requests a Seller Credit (closing credit) to cover the cost of mitigation. The buyer then hires their own contractor after closing. In NY, there is no specific radon disclosure mandate, but general disclosure laws may apply.

A standard sub-slab depressurization system is typically installed in 4-8 hours by a certified professional. The system begins reducing radon levels immediately, and a post-mitigation test is usually conducted 24-48 hours after installation.

The most common and effective system is Active Sub-slab Depressurization (ASD). A pipe is inserted through or below the foundation slab, and a small fan continuously draws radon gas from beneath the home and exhausts it above the roofline, where it safely disperses.

Yes. A properly mitigated home with documentation removes a major buyer objection. In Orange, where the average mitigation costs $1419, the return on investment is highly favorable — especially in Zone 1 areas where buyers actively screen for radon.

While DIY radon mitigation is technically possible, it is strongly discouraged. Improper installation can fail to reduce radon levels or even increase them. In NY, New York does not require state licensing for radon professionals, but the NRPP and AARST certifications are industry standard.. The EPA recommends hiring a certified professional.
