Typical pricing starts at approximately $1,200 per star bolt installation. Final costs depend on the wall condition, number of star bolts required, structural movement, access, engineering requirements, and permit scope. #
Additional costs may include:
- Structural engineer site visit and written report: approximately $600–$800
- Special inspections during construction: approximately $600–$1,000
- Structural drawings and permit plans for city approval: approximately $3,000–$4,000
Structural engineer services, drawings, city permits, and inspections are separate from the installation cost. #
To properly install star bolts, the ceiling area inside the home near the exterior wall typically needs to be opened approximately 3 feet wide along the wall. This allows access for the structural tie-back rods, anchoring system, and reinforcement work required to stabilize the masonry wall safely and correctly.
Because every Philadelphia rowhome and masonry structure is different, all projects should be evaluated individually before final pricing is confirmed.
