Fire Safety Starts at Every Joint

What to Expect From Our Commercial Fire Caulking Process

We apply tested firestop systems with precision, ensuring each penetration is sealed for lasting code-compliant protection.

We begin by reviewing the fire-rated walls, floors and ceiling assemblies on site. Our team identifies the types of penetrations - whether mechanical, electrical or structural - and checks their required fire-resistance rating. This helps us determine the appropriate caulking system for each condition. We also coordinate with other trades to avoid redundant or missed areas.
Proper adhesion is critical for effective fire caulking. We clean all contact surfaces thoroughly, removing dust, debris, oil, or loose material. Any gaps, voids, or improperly cut penetrations are addressed before caulking begins. This prep ensures long-lasting bonds and a clean seal.
We apply UL- and ULC-rated fire caulking products selected for the specific penetration type. Each bead is installed with consistent pressure and proper tooling to fill voids and ensure coverage. We follow manufacturer specifications to meet hourly ratings and inspection criteria. No shortcuts - just clean, compliant, professional work.
Fire caulking must work in harmony with plumbing, HVAC, conduit and data systems. We coordinate timing and placement with other contractors to avoid damage or rework. If access is limited, we use approved methods to reach concealed or recessed spaces. Our attention to detail minimizes project delays and improves pass rates.
Before handoff, we inspect every sealed area for coverage, cleanliness and compliance. Any required firestop labels are applied to assemblies and documentation is completed to support building code inspections. We provide reports or photos upon request to streamline approvals. Once verified, we clean up and sign off with confidence.

Built for Safety, Backed by Code

When Fire Caulking Is the Right Choice

Fire caulking is required wherever pipes, wires, ducts or conduits pass through fire-rated walls, ceilings or floors in commercial buildings. These penetrations compromise the integrity of the fire assembly and must be resealed to meet code. Fire caulking restores that protection, helping slow the spread of flames, heat and smoke in the event of a fire.

This service is critical in hospitals, offices, retail spaces, high-rise condos and industrial facilities. It’s especially important for projects involving fire-rated shafts, stairwells and demising walls. Whether you’re building from the ground up or renovating an older property in Toronto, proper firestopping is a must for compliance and safety.
