Lebanon Township owners ask about active sub-slab depressurization more than you would think for a town this size.
What people describe first
- 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 Lebanon Township
Public supply reaches very little of this township. Where an address is on a private well, that well draws from the same fractured Precambrian gneiss and granite that produces the soil gas — so the water is a second question, not the same one.
Lebanon Township — the state's own numbers
41% of the 2,640 test results NJDEP holds for Lebanon Township 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 Township together with Lebanon Borough as one row, so both carry these figures.
Rural and semi-rural, from 18th and 19th century stone farmhouses to 1970s-onward houses built on cut-and-fill lots carved into the hillsides. Full basements are common because the ground had to be excavated anyway.
Getting the work done in Lebanon Township
Long driveways, sloping lots and plenty of room around most houses, so exterior pipe routing is usually straightforward.
Any permit for this runs through Lebanon Township. NJDEP radon certification has to be current before a business receives anything from us.
The usual approach
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.
What it costs comes down to the foundation, the number of suction points, and where the pipe can run.
Who is allowed to do this in New Jersey
Under N.J.A.C. 7:28-27 this is not work a general contractor may take on. It requires a business certified by NJDEP for radon mitigation, with a certified mitigation specialist directing the work. We verify that on the state register, note the date, and route accordingly — but a verified certification is a fact, not a recommendation.
Never tested, and wondering whether to?
Give us the short version and the timeline. We'll put it in front of crews who can work to it, and tell you honestly if nobody can.
