Firestop Special Inspection
Code officials need proof every wall penetration was sealed correctly
Bottom line
Attractive margins, but operations need a serious buyer.
Firestop special inspection firms inspect, photograph, test, and document fire-resistance-rated wall and floor penetrations in hospitals, labs, apartments, schools, data centers, and commercial construction projects. The surprising angle is that the installer is often not allowed to self-certify: owners and building officials need third-party documentation before occupancy, so the inspection becomes a schedule-critical compliance line item.

How It Works
Inspectors review drawings and submittals, walk job sites, verify listed firestop systems, photograph penetrations, flag deficiencies, re-inspect repairs, and issue reports for owners, GCs, and authorities having jurisdiction. Revenue comes from project inspection fees, hourly re-inspections, consulting, documentation packages, and repeat GC or healthcare-facility relationships.
