Active sub-slab depressurization in Clinton, NJ

Whether active sub-slab depressurization is the right answer in Clinton depends on what is actually under the floor.

When this is the right question

A sale is under contract and the buyer's radon result triggered a repair request
Cracks and utility penetrations through a slab you can see daylight around
A test came back at or above 4.0 pCi/L on a basement or slab home

Why this comes up in Clinton

Here is what makes Clinton particular: the town centre is served by a public supply, so waterborne radon is usually not part of a Clinton Town job — unlike the surrounding township, where it frequently is.

Clinton Town — the state's own numbers

36% of the 5,885 test results NJDEP holds for Clinton Town were at or above the 4.0 pCi/L action level — 2,126 of them. That puts it in Tier 1 — high potential. NJDEP reports Clinton Town together with Clinton Township as one row, so both carry these figures.

Clinton is a small town on the South Branch of the Raritan at the head of Spruce Run, built around the two historic mills, and that shapes what a system here has to be designed around.

Getting the work done in Clinton

Small close-set lots in the historic centre; more room on the outer streets.

Any permit for this runs through Clinton Town. NJDEP radon certification has to be current before a business receives anything from us.

What the work involves

The standard fix. A suction point is cut through the slab, pipe is run up through the house or along an exterior wall, and an in-line fan mounted outside conditioned space pulls soil gas from under the floor and discharges it above the roofline. Sizing follows a diagnostic reading of how permeable the fill under the slab actually is, not the square footage of the house.

Typical cost in Hunterdon County, NJ

$1,200 – $2,600 — 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 Clinton 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.
