Professional Basement Finishing for Tewksbury Homeowners
Tewksbury Township is one of Hunterdon County's most rural and affluent communities, encompassing the villages of Oldwick, Mountainville, and Pottersville in the scenic Tewksbury Trail region. The township features large-lot zoning, preserved farmland, horse properties, and custom homes on acreage that ranges from three to fifty-plus acres. The charming village of Oldwick — with its general store, landmark church, and cluster of estate homes — defines the township's character.
