Broken commercial doors in Milton: we dispatch 24/7.
Milton is roughly a 30-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.
Commercial door systems we install and repair in Milton
A commercial building runs on more kinds of door than most people ever count — a glass entrance out front, hollow metal on the exits, an overhead door on shipping, an operator on the accessible route. Canuck Door Systems supplies, installs and repairs all of them with one crew and one phone number, so "commercial doors" here means the whole building, not one product.
Hollow metal vs glass-aluminum doors
The two door systems a commercial building buys most, and they solve different problems. Hollow metal is strength: a steel slab in a welded steel frame, rated where it needs to be, indifferent to abuse. Glass and aluminum is presence: daylight, visibility and a storefront a customer walks up to. Most buildings need both — the question is which opening gets which.
Fire-rated doors in Milton: the label is the system
A fire-rated door is not a heavier door — it is a listed assembly. Door, frame, hardware and any glazing are tested together, and the rating on the label only holds while all of them match it. That is why a rated opening is specified and installed as one thing, and why swapping a closer or cutting a lite into a rated door in the field is not a small change.
Planned maintenance instead of emergency calls
Most of the door failures we attend didn't start that week — a dragging closer, a fraying overhead-door cable, a slower operator. A preventative-maintenance plan puts a technician in front of every door on a schedule: hardware adjusted, springs and cables inspected, operators tested, rated doors checked to close and latch on their own. Facility managers use it to turn door repair from a dispatch problem into a line item — and the 24/7 line is still there for the failures that don't wait.
Doors for the work Milton buildings do
The sectors that dominate Milton — distribution centres, logistics, manufacturing — each ask something different of their doors.
Distribution centres
Shipping runs on dock levelers, dock seals and sectional or rolling steel overhead doors — and a bay door that won’t lift is a stopped truck, which is why these calls get 24/7 dispatch.
Manufacturing
Plants take doors hard: hollow metal doors and frames for forklift and cart traffic, heavy-cycle overhead doors on shipping, and fire-rated doors on the separations between plant and office.
New-build construction
For general contractors: hollow metal doors and frames supplied to the hardware schedule, glass-aluminum systems installed to spec, and fire-rated doors your inspector can sign off.
Condos & property management
Parkade overhead doors, lobby entrances and suite-level fire-rated doors, plus preventative-maintenance plans that let a property manager stop dispatching one repair at a time.
Hotels & hospitality
Entrance systems that carry the front-of-house look, operable walls to divide function space, and hotel-room doors — with repairs booked around guests, not around us.
Food & pharma processing
Processing and clean environments call for double-acting traffic doors on busy corridors and sealed hollow metal doors that stand up to washdown and sanitation cycles.

Common questions about commercial doors
How long do traffic doors take to arrive?
Plan on roughly 4–6 weeks for manufacture once sizes are confirmed, then 1–2 weeks to schedule installation — about 5–8 weeks in total, since panels are made to your opening. Replacement parts are much quicker: hinge cassettes, gaskets, vision-panel glazing and bumper strips are the items that wear, and keeping a small stock of them on site is worth doing if you run a lot of these doors. Fitting the doors at one opening is usually done in a day, often overnight or between shifts.
What is the rough opening for a double steel door?
For a hollow metal frame with a standard two-inch face, the masonry opening is the nominal pair width plus four inches and the nominal height plus two inches — two inches of frame face at each jamb, one at the head. A 6'0" by 7'0" pair therefore needs roughly a 6'4" by 7'2" masonry opening. Crews working to a field-shimmed tolerance add about another half inch of width and a quarter inch of height so the frame can be plumbed rather than forced into place. The arithmetic uses the pair width, not the width of one leaf, and it should be confirmed against the frame schedule before the wall is built.
What type of doors are best suited for exterior commercial use?
A galvannealed hollow metal door in a galvannealed welded frame, in 16 gauge or heavier where the traffic warrants it. The zinc-iron coating is what survives a salted Ontario winter; a factory-primed door left at an exterior opening will rust along the bottom rail within a season or two. Add a sweep and threshold so water leaves the opening, a thermal break where the space behind the door is heated, and stainless rather than paint where washdown or chemicals are involved. Aluminum and glass belong at the front of the building where appearance matters; steel belongs everywhere the door has a job other than being looked at.
