Sprinkler System in Oshawa
Harex provides every service in Oshawa: inspection, testing, repair, installation and verification, with the 24-hour emergency line answered for Oshawa buildings at any hour.
Oshawa Fire Services issues a compliance letter for a building only after every required inspection has been completed and the property is in compliance, so the inspection record is the thing that unlocks the letter.
Oshawa is the largest municipality in Durham Region, with a manufacturing history that left it a stock of older industrial buildings and an economy now built around education and health sciences. Oshawa South and Southeast sit inside two of the Region's Provincially Significant Employment Zones.
Harex forwards every completed sprinkler system report for a Oshawa building to Oshawa Fire Services, so the building is on record as maintained with the department that would otherwise be the one to notice a lapse. The Harex base is in Oshawa, so there is no travel to bill.
Harex also provides sprinkler system in Whitby, Courtice and Clarington.
The system nobody looks at
A sprinkler system in an Ontario industrial building sits untouched for years and looks fine. Then a valve is found closed, a dry system has water sitting in it, or a flow switch never reported to the panel. Inspection exists to catch exactly that, before an insurer or an inspector does.
What we inspect and test
- CONTROL VALVES
- GAUGES & PRESSURE
- FLOW SWITCHES
- TAMPER SWITCHES
- ALARM TRANSMISSION
- FIRE DEPT. CONNECTION
- HEADS & CLEARANCE
- DRY SYSTEM AIR
Because Harex also holds your fire alarm file, we can prove the sprinkler devices actually reach the panel, which is the part that gets missed when two different contractors own the two systems.
Frequency
Harex runs an annual inspection with more frequent checks through the year, set by system type and occupancy. Dry systems and buildings with freeze exposure get closer attention going into winter.

What clients say
across every platform
“Harex has looked after our alarm and extinguishers for years. They come when they say they will, and the report is in our hands before the insurer asks for it.”
“We were told the whole system had to be replaced. Harex asked the fire department why, in writing, and the scope came back a fraction of what we had been quoted.”
“We had thirty days and a list we did not understand. They went through it item by item, told us what was actually required, and we passed the re-inspection.”
“Four buildings, one schedule, one set of reports. I stopped chasing three different contractors for paperwork the month we switched.”
“Panel went into trouble on a Saturday night. Somebody answered, walked our supervisor through it on the phone, and had a technician there before the shift started.”
