Lebanon Borough

Lebanon radon testing and mitigation

Newark Basin shale country. Free referrals to NJDEP-certified radon businesses covering Lebanon.

Lebanon is a very small borough on Route 22 at the eastern edge of the Round Valley country, entirely surrounded by Clinton Township.

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

Water supply. 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.

The ground under Lebanon

Lebanon Borough is one of the smallest municipalities in the county — sitting on Newark Basin ground at the eastern approach to Round Valley,. Its housing is relatively uniform by county standards: modest single-family houses on flat, regular lots, most with basements, most on graded fill. That uniformity is genuinely useful, because it means a properly sited single suction point does the job in the majority of cases and the variables that complicate work elsewhere in the county — steep ground, 18th century stone cellars, private wells — largely do not apply here.

That is the shape of the ground here, not a finding about any one address. The NJ Geological Survey maps the formations; a certified contractor measures what is actually happening beneath a particular slab.

Around Lebanon. The requests come from the Main Street village centre; the streets off Route 22; the residential blocks toward the Clinton Township line; the rail corridor edge of the borough.

Working here

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

What moves the cost here

Lebanon is one of the more predictable places in the county to have a system installed: level lots, side access, and conventional basements. Cost tends to sit at the ordinary end, and where it rises it is usually because a basement has been finished and the owner wants the riser hidden.

Lebanon Borough is very small and entirely surrounded by Clinton Township, so a Lebanon mailing address very often belongs to a property under a different construction office and a different water supply.

Its unusually uniform mid-century housing stock makes it one of the few places in Hunterdon where a standard single-point sub-slab system is the likely answer for most of the town.

Permits and paperwork

Permits go through the Lebanon Borough construction office. Because the borough is surrounded entirely by Clinton Township and shares a postal address with a wider area, confirming the correct office before applying saves a wasted trip.

Because postal addresses and municipal boundaries diverge across this county — and because construction-code services are sometimes shared between towns — the first thing to establish is which office actually has jurisdiction.

NJDEP tierTier 1 — high potential

Tier 1 means at least 25 homes tested with 25 percent or more at or above 4 pCi/L. NJDEP reports Lebanon Borough together with Lebanon Township as one row, so both carry these figures.

Source: New Jersey Department of Environmental Protection, Radon Section, 2015 Radon Tier Assignment Report (May 2015). NJDEP's figure is a cumulative count of test results in its dataset, not a count of distinct homes. These are municipality-wide totals and say nothing about any individual property — only a test does that.

System running and the reading hasn't moved?

One description is enough. We'll send it to certified local crews and leave the decision entirely with you.
