Commercial Door Repair & Service

Common commercial door repair costs in Canada (2026): broken spring (overhead) $250–$650 per spring; cable replacement $180–$450; opener motor replacement $850–$2,200; sectional panel replacement $480–$1,400; track repair $220–$680; bottom seal replacement $90–$220; dock leveler hydraulic cylinder $640–$1,500; automatic door operator gearbox $1,400–$3,800; fire door hardware repair $180–$650; full opener and rail rebuild $1,800–$3,800. Emergency 24/7 dispatch adds $180–$420 base call-out. The decision between repair and replacement turns on age (over 15 years often replace), parts availability (orphaned brands), cumulative service cost (over 60% of new = replace), and code compliance (out-of-spec fire doors must be replaced). Our 48-city installer roster covers every commercial-door category — overhead, fire-rated, automatic, dock, security — and every quote ships with stamped engineering. ULC-certified installers staff each region from St. John's to Victoria.

Replace when (a) age exceeds 15 years and major components have failed, (b) cumulative repair cost in 24 months exceeds 60% of replacement cost, (c) parts are no longer manufactured, (d) the door fails fire/security/accessibility code and cannot be brought into compliance, or (e) damage exceeds 30% of the door surface. Repair when (a) door is under 10 years old and damage is localized, (b) the issue is a single failed component (spring, cable, opener) on an otherwise sound door, or (c) the manufacturer still supports parts. A diagnostic visit ($150–$320 typical, often credited toward repair) gives a written recommendation. Get the recommendation in writing — verbal estimates favour the contractor, not your budget.

A commercial door is engineered for high-cycle use, code compliance, and the operational demands of business and institutional buildings — not residential homes. Commercial doors carry ratings for fire (ULC, NFPA 80), security (UL 437, CPNI), accessibility (CSA B651, ADA), and impact resistance. They use heavier-gauge steel (typically 16–14 gauge for hollow metal vs. 24 gauge residential), reinforced frames, industrial hardware (Grade 1 ANSI BHMA), and operators rated for thousands of daily cycles. Common categories: sectional overhead, rolling steel, automatic entrance, fire-rated, hollow metal, dock equipment, security shutters, and air curtains. The Ontario Building Code, NBC, and provincial fire codes specify which door type is required by occupancy class. Cycle ratings, climate zone, and AHJ requirements drive the final spec — we document each in writing on every CommercialDoors.ca quote. Across our 48-city Canadian network — Toronto, Montréal, Vancouver, Calgary, Edmonton — this answer holds. Province-specific variations (OBC, QBC, BCBC, ABC, NBC, Atlantic) only adjust the code reference numbers, not the engineering principle.

Commercial door cost depends heavily on category and specification. Typical Canadian installed price ranges (2026): hollow metal door + frame $1,200–$3,500; sectional overhead door (10x10 to 14x14) $2,800–$8,500; rolling steel door $3,500–$12,000; fire-rated assembly with hardware $2,500–$6,000; automatic sliding entrance with operators $8,000–$22,000; loading dock door + leveler + seal package $12,000–$28,000; high-speed roll-up door $14,000–$35,000; hangar bi-fold (50x14 small aircraft) $35,000–$95,000. Pricing variables include insulation R-value, wind/snow load engineering, opener horsepower and cycles, and hardware grade.

Province-specific code variations adjust only the citation numbers, not the engineering principle.
