Commercial Overhead Door Specialists — All Business Types Served
A Commercial Door That Won’t Open Costs You Money Every Minute It’s Down
A malfunctioning commercial garage door disrupts operations, creates security vulnerabilities, and in the case of loading bays, can halt your entire workflow. Whether it is a warehouse overhead door stuck in the raised position overnight, a retail unit’s rollup door that refuses to close, or a fleet service garage with a door off its tracks at 6 AM — SOS Garage Doors provides priority commercial service across Toronto, Mississauga, Brampton, Vaughan, Markham, Hamilton, and every GTA commercial hub with same-day certified technicians dispatched within the hour.
Commercial garage doors are built to a higher cycle rating and load specification than residential doors, and they require technicians who understand the differences. Heavy-duty torsion spring systems, industrial-grade trolley openers, high-cycle commercial operators, and rolling steel shutter mechanisms all require specific expertise and parts. Our commercial technicians are trained and equipped for all of these systems. We service all major commercial door types: sectional overhead doors, rolling steel shutters, high-speed doors, fire-rated doors, and loading dock doors — for auto shops, car dealerships, distribution centres, food warehouses, retail plazas, self-storage facilities, and light industrial units across the GTA.
If your commercial door failure is also affecting your garage door opener or access control system, our technicians handle all connected systems in the same visit. For businesses that also have residential properties or need standard residential door service, our residential garage door services page covers all home door needs under one roof. If a vehicle impact has damaged door panels in addition to the mechanical system, our garage door panel replacement team sources commercial-grade replacement sections and completes the swap as part of the same job. For businesses concerned about after-hours security due to a door failure, we treat that as an emergency — our team handles emergency garage door repair 24/7 across the entire GTA.

All Commercial Door Types & Business Sectors Covered
Our Commercial Garage Door Services Include
From a single-unit auto shop to a multi-bay distribution centre — SOS Garage Doors handles every commercial overhead door need across the GTA.
Sectional Overhead Door Repair & Service
Commercial sectional overhead doors are the most common business entry point. We repair and service all components — high-cycle torsion springs rated for 50,000+ cycles, heavy-duty trolley openers, cable systems, tracks, and panels — for all major commercial door brands.
Rolling Steel Shutter Repair & Installation
Rolling steel shutters require specialist knowledge and parts. We repair and replace shutter slats, spring barrels, guides, and operators. For shutters that will not raise or lower, most repairs are completed same-day with commercial shutter parts stocked on our trucks.
Commercial Opener Repair & Replacement
Commercial operators handle far higher cycle volumes than residential openers. We repair and replace commercial-grade operators from LiftMaster, Chamberlain, Genie, and other commercial lines — including jackshaft, trolley, and wall-mount configurations.
Loading Dock Door Service
Loading dock doors operate under extreme conditions — frequent cycling, heavy impact, and weather exposure. We service dock doors including door panels, spring systems, counterbalance hardware, and bottom seals — with same-day priority response for dock failures that stop operations.
High-Speed Door Service
High-speed roll-up doors for cold storage, food processing, and high-traffic facilities require specialist service. We service door curtains, guide rails, wind bars, photocell sensors, and high-speed operators — and can source replacement curtains for all major brands.
Fire-Rated Door Inspection & Repair
Fire-rated commercial doors must operate correctly in emergencies. We service fire door drop mechanisms, fusible links, and closing hardware — and provide documentation of inspection for compliance purposes.
Auto Shop & Dealership Door Service
Auto shops, dealerships, and fleet service facilities operate garage doors at high daily cycle volumes. We provide priority service to these facilities, stock high-cycle commercial springs and openers, and offer maintenance contracts to prevent costly downtime.
Commercial New Door Installation
New commercial door installation for retail units, warehouses, industrial buildings, and self-storage facilities. We measure, supply, and install all commercial door types — including removal of existing doors, header and track work, and full operator setup.
Preventative Maintenance Contracts
Scheduled quarterly or annual maintenance is the most reliable way to prevent commercial door failures. Our maintenance visit includes full spring inspection, cable check, track lubrication, operator adjustment, bottom seal check, and a written condition report.
