Commercial Sprinkler Inspection, Installation & Repair
Sprinkler Systems.
Designed & Maintained.
Commercial sprinkler system design, installation, inspection, and 24/7 emergency repair across Ontario. NFPA 13 certified, engineer-stamped drawings.
From pipe layout to post-discharge reset. The complete sprinkler stack.
A sprinkler system is the most effective single fire-protection device ever invented. But it only works if it's designed right, installed right, and maintained. Boss Fire handles every phase: engineer-stamped design drawings for new construction, routine inspections and testing for operating properties, and 24/7 emergency repair when a pipe bursts or a head discharges.
We work on wet-pipe, dry-pipe, pre-action, and deluge systems. From small retail units to multi-building industrial properties.
Burst pipe at 2 AM? Our on-call technicians respond 24/7 for sprinkler emergencies across the GTA.

Sprinkler systems
we inspect and service.
Wet-Pipe
The most common system. Pressurized water in the pipe, ready to discharge instantly. Works in heated spaces.
Dry-Pipe
Pipes are pressurized with air; water releases only when a head activates. Ideal for parking garages and cold-storage.
Pre-Action
Requires two triggers (detection + head activation) before water flows. Protects data centres, museums, and archives.
Deluge
All heads open simultaneously. Used in high-hazard industrial settings where fire spreads fast.
Fire Pump
Boosts water pressure where municipal supply isn't adequate. Annual full-flow testing required.
System Retrofit
Bring older systems into NFPA 13 compliance. Head replacement, corrosion remediation, pipe renewal.
The NFPA 25 sprinkler
schedule at a glance.
The Ontario Fire Code references NFPA 25 for water-based fire protection systems. The building owner is responsible for keeping the system inspected and the records complete.
| Frequency | Key tasks |
|---|---|
| Weekly / monthly | Control valves checked open and sealed or locked (weekly when not electronically supervised). Gauges checked weekly on dry-pipe, pre-action and deluge systems, monthly on wet-pipe systems. |
| Quarterly | Waterflow alarm devices tested, supervisory signals checked, fire department connections inspected. |
| Annually | Sprinkler heads, piping, hangers and bracing inspected; main drain test; dry-pipe and deluge valve trip tests; fire pump flow test where present. |
| Every 5 years | Internal pipe assessment for corrosion and obstruction, gauges replaced or recalibrated, standpipe flow tests, check valve internals examined. |

Sprinkler service across the GTA
How often do sprinkler systems need inspection? +
Under NFPA 25, commercial sprinkler systems require a tiered inspection schedule: weekly gauge checks, monthly control-valve inspection, quarterly flow tests, annual full inspection, and 5-year internal pipe inspection. Boss Fire consolidates all of these into one managed service so nothing falls through the cracks.
What do I do if a sprinkler head accidentally discharges? +
Call 905-519-BOSS immediately. A single-head discharge can release hundreds of gallons of water per minute until the system is shut down. Our 24/7 emergency team will shut off the riser, drain the system, replace the head, and re-pressurize. Usually within a few hours.
Does my building need a sprinkler system? +
Under the Ontario Building Code, sprinkler systems are required in commercial buildings over 600 sqm (roughly 6,500 sqft), in high-rise buildings regardless of size, and in occupancies with high fire load (warehouses, industrial, assembly). A Boss Fire engineer can review your property and tell you definitively.
Do you handle fire pump testing? +
Yes. Annual full-flow fire pump testing is a critical (and frequently failed) NFPA 25 requirement. Especially in high-rises. Our technicians have the certifications, equipment, and documentation protocols to perform it correctly.
