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.

The SOS Garage Doors Difference

Why GTA Businesses Choose SOS for Commercial Door Service

Commercial clients need a different level of responsiveness than residential. We understand that downtime costs money and that security cannot wait. Our commercial service is built around that reality.

Priority Commercial Dispatch

Commercial calls receive priority dispatch. We understand that a stuck loading bay door at your warehouse is not a scheduling item — it is an operational emergency. We respond accordingly across the entire GTA.

Commercial-Grade Parts in Stock

We carry commercial torsion springs, industrial-grade trolley assemblies, high-cycle opener components, and rolling shutter parts. Most commercial repairs are completed in a single visit with no special-order delays.

All Commercial Door Types Serviced

Sectional overhead doors, rolling steel shutters, high-speed roll-up doors, fire-rated doors, dock leveller doors — our commercial technicians are trained and certified on all configurations.

24/7 Emergency Commercial Response

A commercial door stuck open overnight is a critical security and liability issue. Our emergency team is available 24 hours a day, 7 days a week including holidays — for businesses that cannot wait until morning.

Written Quote — No Hidden Charges

Commercial clients receive a full written quote before any work begins. We document scope, parts, and labour clearly. No surprise line items on the invoice. Transparent billing every time.

Preventative Maintenance Contracts Available

For high-cycle commercial doors, scheduled maintenance is the most cost-effective strategy. We offer quarterly and annual maintenance contracts that reduce unexpected failures and extend door service life significantly.

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.

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.

Frequently Asked Questions — Commercial Garage Door Services

Questions we hear most often from business owners and facility managers across the GTA.

How quickly can you respond to a commercial door emergency?

Commercial calls receive priority dispatch. In most GTA cities we can have a certified commercial technician on-site within 1–3 hours. For after-hours emergencies, our 24/7 emergency line connects you with a live dispatcher immediately.

Do you service commercial doors that are different from residential?

Yes — and importantly, our commercial technicians are specifically trained for commercial-grade systems. High-cycle torsion springs, commercial trolley openers, rolling steel shutters, and dock doors all require different parts and techniques than residential doors.

Can you repair a rolling steel shutter?

Yes. We service and repair rolling steel shutters including slat replacement, spring barrel repair, guide track work, and operator service. Most rolling shutter repairs are completed same-day with parts stocked on our commercial trucks.

Do you offer maintenance contracts for commercial properties?

Yes. We offer quarterly and annual maintenance contracts tailored to the door’s cycle volume and operating environment. Scheduled maintenance is significantly more cost-effective than emergency repairs and extends commercial door service life by years.

My loading dock door is stuck open overnight. Can you come now?

Yes. Call our emergency line — a live dispatcher answers 24/7. We treat an open commercial door as a security and liability emergency and prioritize dispatch accordingly.

What commercial door brands do you service?

We service all major commercial door brands including Clopay, Wayne Dalton, Cornell, Overhead Door, and others. For commercial openers, we service LiftMaster, Chamberlain, Genie commercial lines, and more.

Do you handle new commercial door installations?

Yes. New commercial door installation for retail units, warehouses, industrial units, and self-storage facilities — including old door removal, header and track work, and full operator installation. We provide a site visit and written quote.

Is there an after-hours premium for emergency commercial service?

Yes. There is a standard after-hours service premium for calls outside regular business hours. We communicate this clearly before dispatching — no hidden fees, no surprise invoices.
