The situations this follows from

  • An open sump pit sitting in a finished basement
  • A visible gap where the slab meets the foundation wall
  • Utility penetrations and floor drains with nothing around them

Why this comes up in Quakertown and Pittstown

Public supply barely reaches this township. A Franklin Township well draws from the western Newark Basin rock that also delivers the soil gas, which makes two measurements the complete answer rather than one.

Franklin Township — the state's own numbers

Open rural lots with room to work; village properties are tighter.

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

How it's normally done

Sealing on its own rarely brings a house below the action level and should not be sold as though it will. What it does is make an active system work harder for its money by cutting the leakage paths that otherwise short-circuit the suction — so it is nearly always done as part of an install rather than instead of one.

Typical cost in Hunterdon County, NJ

$400 – $1,300 — 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.

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.
