Loading dock, warehouse and storefront door service for businesses across the GTA.

Commercial garage door service across the GTA

When a loading-dock door fails, every minute costs your business money. Master-Tech serves warehouses, distribution centers, auto shops, body shops, fire halls, storage facilities and storefronts across the GTA with priority commercial response, after-hours service and preventative maintenance contracts that keep your operation moving.

Doors and operators we service

Sectional steel doors, high-speed roll-up doors, grilles, dock levelers and seals, jackshaft and trolley operators, and integrated dock equipment. We work with all major commercial brands including LiftMaster Commercial, Manaras, Richards-Wilcox, Steel-Craft and Garaga Commercial.

Preventative maintenance contracts

A planned maintenance contract is the cheapest insurance a facility manager can buy. We schedule quarterly or semi-annual visits, inspect cables, springs, rollers, photo-eyes, openers and seals, lubricate every moving part, and document everything for your records — preventing the breakdowns that shut down operations.
