Short-term radon test in Oldwick

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 Oldwick depends on what is actually under the floor.

How this normally comes up

  • A buyer or a lender has asked for a radon test before closing
  • A neighbour tested high and you have never tested at all
  • You finished a basement and want to know what you have been sitting in

Why this comes up in Oldwick

Outside the small village supply this is well country. A Tewksbury well draws from the same upland rock that puts the soil gas under the floor, which is why the water side comes up here so often. That is part of the context any crew working in Oldwick has to design around.

Tewksbury Township — the state's own numbers

46% of the 1,538 test results NJDEP holds for Tewksbury Township were at or above the 4.0 pCi/L action level — 711 of them. That puts it in Tier 1 — high potential.

Oldwick is the historic village at the centre of Tewksbury Township, in the rolling country below the Highlands ridge, and that shapes what a system here has to be designed around.

Practicalities in Oldwick

Tight in the village core; very open on the surrounding estate-scale lots.

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

What a certified crew will do

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 sooner it is measured, the more of the options stay open.

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.
