Professional Firestopping Solutions

Reliable firestopping solutions designed to protect fire-rated assemblies and help prevent the spread of fire and smoke across NYC and Miami, FL buildings.

Protecting Fire-Rated Assemblies

Firestopping helps preserve the integrity of fire-rated walls, floors, and assemblies by protecting openings created for essential building services throughout key building areas.

Modern buildings require pipes, conduits, cables, and mechanical systems to pass through fire-rated walls and floors. These penetrations can create openings that must be properly addressed to help maintain the intended fire-resistance of the assembly. NY Firestop provides professional firestopping solutions for these critical areas across NYC and Miami, FL, with careful attention to project requirements, installation details, and applicable fire and building codes. Our approach focuses on precise workmanship and dependable protection throughout construction and renovation projects, helping contractors, developers, and building owners maintain safer, properly protected building assemblies.
