How much does foundation underpinning cost per linear foot in New Jersey?

Traditional mass-concrete underpinning in NJ typically runs $1,500 to $3,000 per linear foot of foundation wall, including excavation, shoring, rebar, concrete, and engineering. Helical pier underpinning runs $2,000 to $3,500 per pier, with piers spaced 5 to 8 feet on center.

A small 20-foot section of settling wall commonly lands between $30,000 and $70,000. Underpinning an entire basement perimeter for a floor-lowering project is substantially more.
