The village core is on a borough supply; the slope behind it is less uniform. A well there draws from the rock at the western margin of the basin.

Frenchtown Borough — the state's own numbers

30% of the 658 test results NJDEP holds for Frenchtown Borough were at or above the 4.0 pCi/L action level — 195 of them. That puts it in Tier 1 — high potential.

Frenchtown is a riverside borough on the Delaware at the mouth of the Nishisakawick, opposite Uhlerstown in Pennsylvania, and that shapes what a system here has to be designed around.

What the work involves

Where there is no slab, the ground itself becomes the barrier. Reinforced membrane is laid over the crawl-space floor, sealed to the walls and around the piers, and a suction point beneath it is piped to a fan. Sealing quality is the whole job here — a membrane taped at the seams and left loose at the wall performs nothing like one properly terminated.

Typical cost in Hunterdon County, NJ

$2,000 – $3,800 — typical range, not a quote. What your building needs can only be settled by a certified business that measures it on site.

Local experience matters here — the ground under Frenchtown does not behave like the other end of the county.

Certification, checked before referral

Installing radon mitigation for a fee in New Jersey requires NJDEP certification as a radon mitigation business, affiliated with a certified radon mitigation specialist (N.J.A.C. 7:28-27). We confirm that on the NJDEP register and record the date we checked. That is a check, not an endorsement — satisfy yourself before you hire.

Have a result you don't know what to do with?

One description is enough. We'll send it to certified local crews and leave the decision entirely with you.
