Markham is roughly a 40-minute run from our Mississauga shop — less if a technician is already in the area — so a truck is usually on site the same day.
Emergency board-up, security and make-safe first — permanent repair scheduled after.
The two fire-rated doors a building in Markham uses — steel and wood
A fire door is not a door with a rating written on it. It is a tested assembly — leaf, frame, hinges, closer, latch and any glazing — certified together by a body such as ULC or UL, and it performs as certified only while every part of it stays as it was listed. Which of the two materials goes into a given Markham opening is settled by where the door sits in the building rather than by budget: steel where the door is a tool, mineral-core wood where the door is part of the interior.
Where a building in Markham carries fire-rated openings
The rating belongs to the wall first. The Ontario Building Code assigns a fire-resistance rating to a fire separation, and the closure in it — the door — gets a matching rating. In Markham that lands on the same handful of openings in almost every building, and the count is usually higher than the owner expects.

Fire-rated openings for the work Markham buildings do
The sectors that dominate Markham — technology campuses, corporate offices, light manufacturing — each put fire-rated doors in different places.
Technology campuses
Stair doors are the largest single group in the building, floor by floor, usually temperature-rise rated and on exit devices. After a fit-out the two findings are always the same: a card reader drilled into a fire-rated leaf, and clearances thrown out by a new floor finish.
Light manufacturing
The walls that carry a rating are the ones around the process area and the electrical room, and the doors in them are steel because the leaf is in a plant. The recurring finding is a fire-rated door propped open for airflow or cable runs — the legal version of that is a magnetic hold- open tied to the alarm.
Retail plazas
A unit in a plaza or mall carries fire-rated openings the tenant never thinks about: the back-of-house door onto the service corridor, the stock-room separation, and the mall front itself, which on a fire-rated common area closes with a shutter or curtain on alarm rather than with the shopfront glass.
Schools & institutions
Corridor and stair-lobby doors sit on the route everybody uses when the alarm sounds — which is the same route students lean on, wedge and slam. Buildings here span decades, so one corridor can hold three generations of assembly and the first job is establishing what is actually there.
Condos & property management
Garbage and chute rooms, storage rooms, the parking-level separation and the suite entries: the four groups an inspection always visits, and the four a manager is asked to produce paperwork for. Across a portfolio it is a scheduling exercise more than a door one.
Hotels & hospitality
Guest-room doors are fire-rated at the corridor and finished on the guest side, hung by the hundred, so a floor is refurbished as a set rather than a door at a time. The kitchen and servery pass-throughs are the wide openings, and those close on shutters.

Common questions about fire-rated doors
What makes a fire door fail an inspection?
Almost always the things people do to make a door convenient. Held open with a wedge or a hook, painted over or missing labels, a closer removed or disconnected, a latch that does not throw, gaps at the frame outside the permitted range, holes drilled for a new lock or card reader, and glazing or kick plates that were never part of the listing. Fire and structural damage show up too, but the common failures are alterations, not accidents.
Can you repair a fire door, or does it have to be replaced?
Many deficiencies are repairable within the listing — replacing a closer or latch with a certified equivalent, refitting hardware, correcting clearances, repairing a frame, and re-labelling in some cases. What cannot be repaired is an unauthorised field modification: a hole cut for a lock, a lite kit added after the fact, or a leaf cut down to fit a new floor. Those are replacement, because there is no legitimate way to restore the listing.
How long does a fire-rated door take?
Typically 4–6 weeks to produce a labelled door and frame once the shop drawings are approved, then 1–2 weeks to schedule the job and install it, depending on the size of the project. Certified assemblies are made to order with the hardware prep in the leaf, so the schedule is set by the fabrication rather than the installation. Inspections and most repairs, by contrast, are scheduled in days. Hanging a single labelled door and frame is usually a day on site; a building's worth of rated openings on a new build is scheduled over several weeks with the general contractor.
