Active sub-slab depressurization in Lebanon

One or more suction points through the slab, sealed pipe to above the roofline, and a fan outside the living space. The system most Hunterdon houses get.

Lebanon owners ask about active sub-slab depressurization more than you would think for a town this size.

When this is the right question

  • A finished basement that is used as living space and has never been tested
  • A test came back at or above 4.0 pCi/L on a basement or slab home
  • Cracks and utility penetrations through a slab you can see daylight around

Why this comes up in Lebanon

The built-up borough has a public supply. Addresses at the edges may not; a well there draws from the Newark Basin ground on the approach to Round Valley. That is part of the context any crew working in Lebanon has to design around.

Lebanon Borough — the state's own numbers

41% of the 2,640 test results NJDEP holds for Lebanon Borough were at or above the 4.0 pCi/L action level — 1,089 of them. That puts it in Tier 1 — high potential. NJDEP reports Lebanon Borough together with Lebanon Township as one row, so both carry these figures.

A modest village of mid-century and older single-family houses on small regular lots, with some newer infill.

What access looks like here

Level, regular lots with usable side access on most properties.

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

How it's normally done

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 Lebanon does not behave like the other end of the county.

What we confirm before anyone calls you

This is certified work in New Jersey, not general home improvement. We look up the business on the NJDEP radon register, confirm the mitigation certification is active, and record the date. Insurance is not part of that check, and nothing here should be read as confirming that any business carries liability cover. None of that is an endorsement of their workmanship — get more than one quote.

Never tested, and wondering whether to?

Send us the reading and your town. We'll pass it to certified local crews and get out of the way. Free, and you're not committing to anything.
