Sealing, sump covers and slab-crack closure in Lebanon, NJ

Whether sealing, sump covers and slab-crack closure is the right answer in Lebanon depends on what is actually under the floor.

Why this comes up in Lebanon

Here is what makes Lebanon particular: 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.

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.

Lebanon is a very small borough on Route 22 at the eastern edge of the Round Valley country, entirely surrounded by Clinton Township, and that shapes what a system here has to be designed around.

What the work involves

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.

Local experience matters here — the ground under Lebanon 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.
