Sprinkler System Inspection & Testing in London, ON
Sprinkler System Inspection & Testing works the same way across Ontario on paper — but in London, who enforces it, how fast trades can attend, and what buildings typically need all have a local shape.
Canadian fire codes require water-based fire protection systems — sprinklers, standpipes, fire pumps — to be inspected, tested and maintained in conformance with NFPA 25. The standard sets a strict calendar: weekly and monthly gauge checks, annual main drain and flow tests, five-year internal pipe inspections, and sample testing of older heads.
How it works in Ontario
The rules that govern this in Ontario flow from the Ontario Fire Code (O. Reg. 213/07), and your paperwork ultimately answers to the Office of the Fire Marshal and your local fire service — our local partners work with them constantly.
Sprinkler System Inspection & Testing for London properties
What makes London specific: the Residential Rental Units Licence has required licensing of smaller rental buildings since 2011 — one of Ontario’s longest-running rental licensing regimes — with fire and building inspections tied to renewal.
Typical London clients for this service: landlords answering municipal or insurer letters, buyers in due diligence, condo boards keeping their statutory calendar, and business owners fitting out or renewing leases.
Common failures we find
Closed or tampered valves are the classic cause of sprinkler failure in real fires, which is why valve supervision and monthly checks matter. Painted heads, corroded dry-system piping, missing spare-head cabinets and out-of-date fire pump tests round out the usual deficiency list.
The process
The path from enquiry to closed file usually looks like this:
- Tell us the system types on site — wet, dry, standpipe, fire pump — and the building profile.
- We match a licensed sprinkler contractor in your area.
- The contractor performs the due inspections and flow tests.
- You receive signed NFPA 25 reports and a deficiency quote if issues are found.
- We can set up the recurring annual program so no cycle is missed.

Frequently asked questions
What is a main drain test?
A controlled flow from the system’s main drain that verifies the water supply hasn’t degraded — one of the fastest ways to catch a partially closed valve or supply problem.
Do residential buildings need this?
Any building with a sprinkler system does, including condos and apartments. The condo corporation or building owner is responsible, not individual residents.
Which authority handles this in London?
Day to day, enforcement in London runs through the municipal officials (building, fire prevention, by-law) with the Office of the Fire Marshal and your local fire service as the provincial authority behind them under the Ontario Fire Code (O. Reg. 213/07). Our local partners deal with both routinely.
