Basement Waterproofing Contractors in Hunterdon County, NJ
Hunterdon County is New Jersey's clearest case for planning waterproofing and radon together. In NJDEP's 2015 radon report, almost every Hunterdon municipality is Tier 1, and the county's Delaware River towns learned in 2021 how fast a basement can fill.
Radon in nearly every Hunterdon town
Readington Township had 1,635 of 4,041 tested homes at or above 4 pCi/L, about 40%. Clinton Township had about 36% of 5,885, Raritan Township and Flemington about 35%, and Lambertville about 26%. Union Township, at about 14%, is the one Hunterdon municipality in the report's county list placed in Tier 2.
For a Hunterdon County homeowner, that makes a sealed sump lid, careful crack injection and a radon test after the work routine parts of any basement job, not extras.
Rock under Hunterdon County
The New Jersey Geological Survey places major portions of Hunterdon in the Highlands, built on metamorphosed Proterozoic rock, and most of the rest in the Piedmont, on folded and faulted Triassic and Jurassic sedimentary rock. Neither is the loose sand of South Jersey.
Exterior waterproofing in Hunterdon County can mean digging along rock and on sloped lots, so ask the contractor how ledge or boulders would affect the schedule and price.
Lambertville, September 2021
When Ida's remnants swelled the Delaware River on September 1, 2021, Lambertville officials said more than half of the city's homes suffered moderate to severe flood damage. The mayor described 6 to 9 feet of water in basements that had never flooded, and homes on the north end that hadn't flooded since 1955 were badly damaged.
Residents on North Union Street, a block off the river, described water coming up through basement doors. For Hunterdon homes in the river towns, backflow protection, raised mechanicals and pumps with backup power deserve as much attention as wall sealing.
