- 24/7/365 Garage Door Services
Commercial garage door repair is a specialized service involving the diagnosis and repair of sectional overhead doors, rolling steel doors, fire-rated doors, high-speed doors, dock levelers, and industrial door operators used in warehouses, loading docks, manufacturing facilities, and commercial buildings. At Calgary Garage Door Fix, we provide same-day and 24/7 emergency commercial door repair across Calgary, Airdrie, Cochrane, Chestermere, and Okotoks. When your bay door fails, your business stops—call (403) 990-9536 and we’ll dispatch a commercial technician immediately.
Commercial doors differ fundamentally from residential systems. They’re engineered for heavier weights (400–2,200+ lbs), higher cycle counts (15–60+ cycles per hour vs. 3–5 for residential), and continuous-duty operation. They require operators with industrial motors, heavy-gauge hardware, and safety systems that meet UL 325 commercial standards. Our technicians are trained on these systems and carry commercial-grade parts for on-site repairs.

Our technicians service all commercial and industrial door systems. Here’s what makes each type unique—and what typically fails:
Rolling steel doors consist of interlocking steel slats—typically 20-gauge or 22-gauge galvanized steel in flat or crowned profiles—that coil around a barrel assembly above the opening. Available in 2″ or 3″ slat widths. These doors are ideal for security-critical applications because there are no panels that can be forced open.
Specifications: Standard configurations span openings up to 14 feet wide by 14 feet tall. Wind load ratings range from 20 PSF standard to 31 PSF with heavier gauge slats. Steel, aluminum, or stainless steel construction available.
What we repair:
Fire doors are life-safety equipment required by building codes in openings between fire-rated walls. We service UL-rated fire doors with Class A, B, or C ratings providing 45-minute, 90-minute, or 3-hour fire protection in compliance with NFPA 80 standards.
How fire doors work: Heat-sensing fusible links (typically rated at 165°F) release the door during a fire. Viscous governors control descent speed for smooth, quiet closure. The door seals the opening to contain fire and smoke spread.
What we service:
Compliance note: Fire doors require annual inspection and testing per NFPA 80. We perform fire door inspections, drop tests, and provide documentation for your fire safety records.
Commercial sectional doors operate like residential doors but are built for industrial duty. They feature reinforced steel panels (typically 24-gauge or heavier), heavy-duty 3″ track systems (vs. 2″ residential), and high-cycle torsion springs rated for 50,000–100,000 cycles. Standard configurations include standard lift, high lift, vertical lift, and low headroom depending on ceiling clearance and operational requirements.
Common applications: Warehouses, distribution centers, service bays, loading docks, manufacturing facilities.
What we repair: Torsion springs (commercial wire sizes .250″–.312″), lift cables (7×19 galvanized aircraft cable, 3/16″–1/4″ diameter), cable drums (rated 750–1,100 lbs per drum), 11-gauge and 12-gauge commercial hinges, 3″ sealed-bearing rollers, track sections, and safety bottom brackets rated for 2,200 lb doors.
High-speed doors open at 24–80 inches per second (compared to 6–12 inches per second for standard commercial doors), minimizing air exchange between climate-controlled zones and reducing energy costs in high-traffic openings. These doors can cycle thousands of times per day.
Common applications: Cold storage, food processing, pharmaceutical facilities, manufacturing clean rooms, busy loading docks, parking structures.
What we service: Fabric roll-up curtains, rigid panel systems, bottom bars, side guides, control systems, safety devices, and high-cycle motors.
For temperature-controlled facilities, insulated commercial doors feature polyurethane or polystyrene core panels with R-values from R-6 to R-17+. Critical for Calgary’s climate where maintaining interior temperatures affects both energy costs and product integrity.
What we repair: Insulated panels (maintaining thermal break), perimeter weatherstripping, bottom seals, and ensuring proper door balance to prevent seal gaps.
Doors operated by chain hoist mechanism rather than electric operators. The hoist connects to a floor-level disconnect chain, allowing personnel to raise or lower the door manually. Common in older facilities, as backup systems, or where power isn’t available.
What we repair: Pocket wheels, chains, chain guards, gear reducers, disconnect mechanisms, and manual locking systems.
Commercial door operators are industrial motors designed for high-cycle, continuous-duty operation. Unlike residential openers rated for 3–5 cycles per hour, commercial operators handle 15–60+ cycles per hour depending on the application. We service all major commercial operator types and brands.
Jackshaft operators mount beside the door and connect directly to the torsion shaft via chain or belt drive. They’re the most common commercial operator type, suitable for sectional doors with standard lift, vertical lift, or high lift track configurations.
Specifications we work with:
Trolley operators mount to the ceiling and connect to the door via a trolley arm and rail system—similar to residential openers but built for commercial duty. Used on sectional doors with standard lift tracks where headroom allows ceiling mounting.
Features:
These operators include an integrated chain hoist for manual operation during power outages or emergencies. The hoist connects to a floor-level disconnect chain with electrical cut-out feature, allowing personnel to raise or lower the door by hand. Required for many commercial applications where emergency egress is critical.
Brake systems: Commercial operators use solenoid-actuated disc or drum brakes to prevent door coasting and maintain position. When brakes fail, doors drift down under their own weight or fail to hold position. We replace brake bands, brake drums, solenoids, and perform brake adjustments.
Circuit boards: Modern commercial operators use solid-state circuit boards to control motor direction, limit positions, safety device monitoring, timer functions, and radio receiver operations. We stock replacement boards for LiftMaster (Logic 5 series), Micanan (Smart 5.0), Manaras, Linear, and other major manufacturers.
Motors and capacitors: Commercial motors experience higher stress due to heavier doors and more frequent cycles. Common failures include capacitor failure (motor hums but won’t start), winding burnout, bearing failure, and thermal overload trips.
Drive components: V-belts, pulleys, roller chains, sprockets, gears, and friction clutches all wear under high-cycle operation. We replace worn components and adjust clutches to protect doors and operators from obstruction damage.
Limit switches: Micro switches with adjustable screw cams control door travel limits. Worn or misadjusted limits cause doors to travel too far or not far enough.
Commercial door operators must comply with UL 325 standards for entrapment protection. This standard requires monitored safety devices—if the safety circuit is compromised, the control board must detect the failure and prevent door operation until repaired.
Monitored photocells: Infrared transmitter/receiver pairs that detect obstructions in the door opening. Commercial photocells must be “monitored”—the control board continuously checks that both sensors are functioning. If a sensor fails or is disconnected, the door won’t operate (failsafe design).
Photoelectric sensing edges: Rubber sensing edges mounted to the door’s leading edge containing photoelectric sensors. When the edge contacts an obstruction, it triggers door reversal. Used on sectional doors where traditional photocells aren’t practical.
Electro-mechanical safety edges: Pressure-sensitive edges with electrical switches. Contact activates a switch causing the door to reverse. Available for doors up to 14 feet wide (one switch) or wider (two switches).
Safety inertia brakes: Installed on the torsion shaft, these brakes provide bearing support and prevent door free-fall if sudden acceleration occurs (such as spring breakage). Common on commercial sectional door applications.
We diagnose safety system faults, replace sensors, realign photocells, and ensure your safety systems meet UL 325 requirements.
We understand that different industries have unique requirements for their commercial doors. Here’s how we help Calgary businesses:
✅ Warehouses & Distribution Centers
Calgary’s logistics sector depends on reliable loading dock doors. We service single-bay operations to multi-door distribution facilities throughout Calgary’s industrial parks. Common issues include dock leveler failures, door damage from forklift impacts, and high-cycle wear on springs and operators.
Our approach: Fast response to minimize shipping delays, high-cycle components (50,000+ cycle springs, sealed-bearing rollers), and preventive maintenance programs to reduce unexpected failures.
✅ Manufacturing & Industrial Facilities
Production facilities can’t afford door-related downtime. We service doors in manufacturing plants, machine shops, fabrication facilities, and processing plants throughout Calgary’s industrial zones including Foothills Industrial, Highfield, Manchester, and Franklin Industrial.
Our approach: 24/7 emergency service for critical operations, heavy-duty components rated for industrial use, and scheduled maintenance during off-hours to avoid production disruption.
✅ Auto Shops & Service Centers
Automotive service bays need doors that cycle frequently and withstand vehicle traffic. We service independent shops, dealerships, fleet maintenance facilities, and car washes. Car wash environments require stainless steel rollers and corrosion-resistant hardware.
Our approach: High-speed response (every bay hour matters), durable springs and operators rated for frequent cycling, and carwash-grade components where needed.
✅ Retail & Commercial Buildings
From back-of-store loading areas to parking garage entries, retail operations need secure, reliable doors. We service shopping centers, standalone retail, and commercial complexes.
Our approach: Minimal disruption to business operations, security-focused repairs, and aesthetic considerations for customer-facing areas.
✅ Cold Storage & Food Processing
Temperature-controlled facilities require doors that maintain seals and operate reliably in extreme conditions. We service food distributors, cold storage warehouses, and food processing plants.
Our approach: Fast service to prevent product loss, insulated door expertise, high-speed door maintenance for frequent access areas, and low-temperature rated weatherstripping that stays flexible to -40°C.
✅ Fleet Garages & Municipal Facilities
Transit depots, fire stations, city fleet garages, and public works facilities require doors that function reliably around the clock. We service municipal and government facilities across Calgary.
Our approach: Emergency response for public safety facilities, compliance with safety regulations, and preventive maintenance programs.
✅ Parkades & Parking Structures
Parking garage doors face unique challenges: vehicle emissions, temperature extremes, and security requirements. We service residential and commercial parkade doors.
Our approach: Corrosion-resistant components, security system integration, and reliable operation in harsh garage environments.
Based on thousands of commercial service calls across Calgary, here are the most common issues we encounter:
✅ Broken Torsion Springs
Commercial springs handle significantly more weight and cycles than residential springs. They use heavier wire gauges (.250″–.312+” vs. .207″–.262″ residential) and are rated for 50,000–100,000 cycles. When they fail, the door becomes inoperable. We stock commercial spring sizes for same-day replacement and can upgrade cycle life for high-traffic doors.
✅ Operator Brake Failures
Commercial operators use solenoid-actuated disc or drum brakes. Brake failures cause doors to drift down under their own weight or fail to hold position during stops. Symptoms include the door “creeping” down when stopped or failing to stay in partial-open positions. We replace brake bands, drums, and solenoids and adjust brake tension.
✅ Circuit Board Failures
Solid-state circuit boards control all operator functions. Board failures cause symptoms including unresponsive controls, erratic operation, failure to reverse on obstruction, limit switch errors, and communication failures with safety devices. We carry replacement boards for LiftMaster, Micanan, Manaras, and Linear operators.
✅ Damaged Panels & Sections
Forklift impacts, truck strikes, and general wear damage door panels. We can often replace individual sections rather than the entire door, saving significant cost.
✅ Operator/Motor Failures
Commercial operators run more frequently and under heavier loads. We repair and replace chain hoist operators, jackshaft motors, trolley operators, and control systems from all major manufacturers.
✅ Cable & Drum Issues
Frayed cables (individual wire strands breaking, usually near the drum or bottom bracket), cables jumping off drums, and worn drum grooves cause doors to operate unevenly or jam. Commercial doors use heavier cables (3/16″–1/4″ diameter, 7×19 construction) and drums rated for 750–1,100+ lbs per drum. We inspect the entire lift system and replace components as needed.
✅ Track Damage & Misalignment
Forklift impacts, settling, and wear can damage or misalign tracks. Commercial doors use 3″ radius track (vs. 2″ residential), and damage causes binding, noise, and uneven operation. We straighten, repair, or replace track sections.
✅ Dock Leveler Failures
Hydraulic leaks, lip malfunctions, hold-down failures, and deck damage are common dock leveler issues. We service all brands and types of dock levelers.
✅ Safety System Malfunctions
UL 325 requires monitored safety devices. When photocells fail, become misaligned, or lose communication with the control board, the door won’t operate (by design—this is the failsafe feature). We diagnose whether the issue is sensor failure, alignment, wiring, or control board communication.
✅ Rolling Steel Curtain Damage
Bent or damaged slats, worn endlocks, and bottom bar damage are common on rolling steel doors. We can often replace individual slats or sections rather than the entire curtain, saving significant cost.
✅ Weather Seal Deterioration
Calgary’s extreme temperatures (-30°C to +30°C) destroy standard weather seals. Damaged seals allow cold air, moisture, and pests into your facility. We install commercial-grade bottom seals (4″–6″ heights) and perimeter seals using low-temperature vinyl or EPDM rubber that stays flexible in Calgary winters.
