Commercial Garage Doorman services rolling steel, sectional, and dock equipment across Hamilton, Stoney Creek, Burlington, Milton, and Niagara — same-day response, dispatched from our Grimsby base.
A door down at the bay means trucks queue or reroute — every hour it sits broken is an hour of throughput lost.
02
A high-cycle spring has a rated life measured in cycles, not years. Doors that run all day wear out standard springs fast.
03
Scheduled service costs less than emergency service, every time. A planned visit catches the failure before it strands a truck.

Planned maintenance
Quarterly or semi-annual inspection visits. A documented service log for every door on site. Priority dispatch when something breaks anyway — because it will, eventually. One contact, every door on the property.

When a shipping door goes down for real
“Frank and the crew were fantastic, we had a real emergency with our large shipping door. Frank was here quickly and had the door to the point where it could be closed and locked for the night, that afternoon. True to his word they were back the next day and had our shipping door operational in a few hours. He could have taken advantage of the situation, instead the invoice was very reasonable. Thank you Frank, much appreciated.”

Every door type gets one crew, one visit, and one point of contact — from the curtain to the leveller it rolls up to.
Rolling steel doors
Rolling steel curtains take the abuse other doors can't — forklift contact, weather, constant cycling. When the curtain misfeeds or a slat bends, the whole opening stops working, not just one panel.
We repair damaged slats, replace worn curtains, realign guide rails, and service the motor operators that drive them. Most rolling steel repairs are same-day.
Signs you need this
Curtain binds or jumps the guide rail partway through travel
Visible dents or torn slats along the curtain
Motor runs but the door doesn't move, or moves unevenly
Bottom bar doesn't seal flush against the floor

Sectional overhead doors
Sectional overhead doors are the standard for shipping and receiving bays — insulated panels on a track system built for high-lift or standard-lift clearance.
We replace damaged panels without replacing the whole door, service high-lift and standard-lift track configurations, and correct the spring balance that keeps a sectional door from free-falling.
Signs you need this
One or more panels cracked, dented, or delaminating
Door is noticeably heavier or lighter to lift than it used to be
Rollers grinding or track visibly bent
Weatherstripping gapping at the panel seams
alt: "Sectional overhead door with stacked panels and curved overhead track"
Dock levellers & equipment
The door is only half the bay. Levellers, bumpers, shelters, and seals fail on their own schedule, and a bay with a good door and a broken leveller is still a bay that's down.
We inspect and service dock equipment alongside the doors, so one technician visit covers the whole opening instead of two trades and two invoices.
Signs you need this
Leveller doesn't seat flush or hesitates under load
Dock seals torn or compressed flat, letting weather and pests in
Bumpers cracked or missing, trailer contact reaching the building
Shelter fabric torn at the frame

High-cycle spring conversions
Standard torsion springs are rated in the thousands of cycles. A door that runs all day on a multi-shift dock burns through that rating fast, and a spring failure on a heavy sectional door is a safety event, not just downtime.
High-cycle conversions swap in springs rated in the tens of thousands of cycles, matched to the door's weight and cycle count, so the fix addresses the wear rate instead of repeating the same repair every few months.
Signs you need this
Same door has needed spring repair more than once in the past year
Door runs 20+ times a day
Visible gaps or stretching in the spring coils
Door has become noticeably harder to open manually
alt: "Torsion spring coil above a sectional door header"
Planned maintenance programs
Emergency calls cost more and always land at the worst time. A planned maintenance program puts a technician on every door on a schedule, before something fails mid-shift.
Every visit is documented — a per-door service log covering what was inspected, what was adjusted, and what to watch. Program customers get priority dispatch when something breaks anyway.
Signs you need this
Multiple doors on one site with no service history
Doors serviced only after they break
No record of when springs, cables, or safety edges were last checked
Facility has fire-rated rolling doors requiring annual drop tests
alt: "Clipboard with a per-door service log checklist"
24/7 emergency service
A door stuck open overnight is a security exposure. A door stuck closed at 6 AM is a full stop on receiving. Neither one waits for business hours.
The emergency line runs 24/7. Response is prioritized for planned maintenance customers, but every call gets answered.
Signs you need this
Door won't close and the bay is exposed after hours
Door won't open and trucks are queued at the dock
Cable snapped or spring broken with the door stuck mid-travel
Motor operator smoking, grinding, or tripping breakers repeatedly

Commercial Garage Doorman dispatches from its Grimsby base, in the middle of the QEW industrial corridor. Same-day response windows hold across the lakeshore — the base sits inside a short drive of the whole service area, from Hamilton's Bayfront industrial parks through Stoney Creek's warehouse corridor to Milton's logistics hubs and the Niagara border crossings.

Hamilton's port and heavy-industry heritage left a lot of older buildings with hard-worked doors — the kind other companies won't touch. Bayfront and industrial-park facilities run their doors through multi-shift days, and repeat spring repairs are usually a sign the door needs a high-cycle conversion, not another patch. Grimsby dispatch runs straight up the QEW, holding a same-day response window into Hamilton.

Dispatched up the QEW from Grimsby — same-day response windows hold.
The QEW industrial corridor through Stoney Creek is packed with warehousing and light manufacturing — it's the closest concentration of commercial doors to our Grimsby base, and it shows in the response times. Dock-and-door packages cover levellers, seals, and doors in one visit, so a Stoney Creek bay gets serviced end to end without bringing in a second trade.

Milton's growth as a 401-corridor distribution hub has filled it with new logistics facilities — and new buildings still need a door program from day one. Most first-year failures in Milton trace back to commissioning gaps, not age; an early inspection catches what the installer left loose. Planned-maintenance routes make the drive economics work even for multi-door sites spread across the corridor.
