Most star bolt installations on Philadelphia rowhomes take one to two working days for the structural work itself. A standard job involving 4 to 8 bolts on a single wall can typically be completed in a single day once the permit is in hand and materials are staged.
The total timeline depends on whether a Philadelphia L&I permit is required. Permit-required projects typically run 2 to 4 weeks: 3 to 5 days for structural engineering drawings, 5 to 10 business days for L&I review and approval, then 1 to 2 days for installation.
For smaller-scope projects that do not trigger permit requirements, NK Construction can often schedule installation within 1 to 2 weeks of the initial evaluation.
Interior access is required for most installations — the rod must be anchored to the framing from inside. Homeowners should expect 1 to 3 hours of limited access per room affected.
