Broken Commercial Springs
Broken Commercial Springs — Step-by-Step Audit, Precision Spring Calculation, Safety Protocols & CHI Sourcing
When a commercial garage door spring fails, downtime, risk, and repair cost escalate quickly. Dupree Garage Doors restores uptime with a disciplined, code-aware process: a complete system audit, exact spring calculation & balance, strict safety protocols, and high-quality CHI-sourced components. The result is smooth travel, reduced operator strain, and fewer unexpected service interruptions.
- Commercial-grade only: Correct wire size, inside diameter, coil count, and lift drums for heavy doors and high cycles.
- Measured balance: We weigh the door and set counterbalance to spec—no guesswork.
- Safety first: Lockout/tagout, winding bar protocols, and verified travel limits.
- Documented handoff: Settings, parts list, and PM recommendations for your team.
System audit pinpoints wear, imbalance, and impact-related deformation before we calculate replacement springs.
Step-by-Step Audit: Find the Cause, Not Just the Break
- Safety lockout/tagout: Disable power to the operator; secure the opening.
- Visual & tactile inspection: Springs, cones, set screws, center plate, end bearing plates, drums, cables, shaft, rollers, hinges, tracks.
- Measure & weigh: Door weight (with reinforcements and hardware), dimensions, panel count, track type (standard, high-lift, vertical-lift).
- Operator assessment: Horsepower, gear ratio, sprockets, limits, photo eyes/edges, control interlocks.
- Root cause analysis: Fatigue cycles reached? Mis-spec’d wire size? Bent track or binding rollers? Impact damage from forklift?

We calculate correct wire size, inside diameter, and coil count to match door weight, drum type, lift, and target cycle life.
Precision Spring Calculation: Balance, Lift, and Cycle Life
Correct torsion spring specification is a math & measurement exercise—not a guess. We select spring wire size, inside diameter, length, and wind to match your exact door weight, drum type (standard, high-lift, or vertical-lift), and desired cycle life (standard or high-cycle for frequent use). This protects operators from overload, prevents panel “chatter,” and maintains consistent, safe travel.
- Door weight verified with calibrated scale.
- Drum sizing checked to ensure proper cable wrap and lift geometry.
- Paired springs matched for symmetry; no mixing random sizes.
- High-cycle options available for high-traffic bays.
Lockout/Tagout & Operator Disconnect Winding Bars Only (No improvised tools) PPE: Gloves, Eye Protection, Hard Hat as required Limit & Safety Device Verification - Our safety protocol eliminates guesswork and protects your people, equipment, and product flow.
Safety Protocols: Zero-Compromise Procedures
Our technicians follow a strict, repeatable checklist to control risk: disconnect power, secure the shaft, use the correct winding bars, protect the opening, and verify limits and safety devices after repairs. We don’t leave until the door travels cleanly and stops exactly where it should.
CHI Sourcing & Quality Components
We source commercial-grade torsion springs and hardware from CHI and other proven suppliers. Paired springs are matched for rate and cycle rating, cones are properly seated with set screws torqued to spec, and drums/cables are inspected or replaced if wear indicates future failure.
Preventive Maintenance After Repair
Once balance is restored, we recommend a PM cadence based on cycle count and operating environment. Typical checkpoints include balance test, set-screw torque, cable condition, roller bearings, hinge integrity, track plumb/level, operator chain/belt tension, and photo-eye alignment. A small investment in PM prevents costly surprises.

Broken Commercial Springs — FAQs
How fast can you repair a broken spring?
Emergency response is available in greater Houston. Most single-bay spring replacements are completed same-day after audit and parts verification.
Do both springs need to be replaced?
Yes—paired torsion springs should be replaced together to maintain equal rate and balance. Mixing old/new often leads to uneven lift and premature failure.
What is “high-cycle” and do I need it?
High-cycle springs use different wire/length to increase the number of safe cycles before fatigue. If your bay is opened frequently, high-cycle is a smart upgrade.
Why weigh the door if specs are on file?
Real doors gain weight over time due to reinforcements, glazing changes, or repairs. We weigh to remove guesswork and protect operators from overload.
