Active sub-slab depressurization in Hampton

Whether active sub-slab depressurization is the right answer in Hampton depends on what is actually under the floor.

How this normally comes up

• A test came back at or above 4.0 pCi/L on a basement or slab home
• A finished basement that is used as living space and has never been tested
• A sale is under contract and the buyer's radon result triggered a repair request

Why this comes up in Hampton

Here is what makes Hampton particular: the built-up borough has a public system; addresses beyond it generally do not. A well here draws from the carbonate rock of the Musconetcong valley.

Hampton is a small borough on the Musconetcong River at the Warren County line, in the limestone valley below the Highlands, and that shapes what a system here has to be designed around.

Getting the work done in Hampton

Small level lots in the village with reasonable room at the sides of most houses.

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

What a certified crew will do

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.

The sooner it is measured, the more of the options stay open.
