Short-term radon test in Stockton

A 48-hour closed-house test at the lowest lived-in level, placed and read by a New Jersey certified measurement business. The number everything else follows from.

Whether short-term radon test is the right answer in Stockton depends on what is actually under the floor.

The situations this follows from

  • You finished a basement and want to know what you have been sitting in
  • A previous test was done years ago and you have since changed the heating or the ventilation
  • A buyer or a lender has asked for a radon test before closing

Why this comes up in Stockton

The village has a borough supply. Where a property draws its own water instead, the source is the Stockton Formation sandstone the village is built on. That is part of the context any crew working in Stockton has to design around.

Stockton Borough — the state's own numbers

40% of the 888 test results NJDEP holds for Stockton Borough were at or above the 4.0 pCi/L action level — 352 of them. That puts it in Tier 1 — high potential.

Stockton is a very small riverside borough on the Delaware between Lambertville and Frenchtown, and that shapes what a system here has to be designed around.

What access looks like here

Very small lots with houses close together and to the street, so routing options are limited.

Construction permits go through Stockton Borough, and installing radon mitigation for a fee anywhere in New Jersey requires NJDEP certification.

What the work involves

A short-term test means a sealed-house condition for at least 48 hours with a continuous monitor or a pair of charcoal detectors placed at the lowest lived-in level. The house has to stay closed the whole time, which is the part that most often invalidates a result. In New Jersey the placement and the reading both have to be done by a certified measurement business for the result to count in a real-estate transaction.

Typical cost in Hunterdon County, NJ

$150 – $325 — typical range, not a quote. What your building needs can only be settled by a certified business that measures it on site.

The right answer depends on your specific building, which is why somebody has to measure it.

New Jersey requires certification for this

Measurement is certified separately from mitigation. Under N.J.A.C. 7:28-27, testing for radon for a fee in New Jersey requires NJDEP certification as a radon measurement business. A crew certified to install systems is not thereby certified to place and read the detectors. We only route this work to businesses we have checked on the measurement side.
