When to Call a Professional
Know when DIY is safe and when professional help is necessary
NEVER DIY These Repairs
These repairs are dangerous and can cause serious injury or death:
Spring Replacement/Adjustment
Why Dangerous: Torsion springs are under 200-600 lbs of tension. If spring slips during replacement, can cause severe injury (broken bones, lacerations, death).
Professional Tools Required: Winding bars (specific size), proper safety equipment, knowledge of exact spring tension calculations.
DIY Risk: 13,000+ ER visits/year from garage door spring accidents. Professional cost: varies. Not worth the risk.
Cable Replacement
Why Dangerous: Cables also under extreme tension. When cable breaks/releases, can whip with enough force to cause severe injury. Door can fall suddenly.
Professional Process: Requires releasing spring tension safely, replacing cables on both sides, re-tensioning springs precisely.
Cost: varies for cable replacement. Much cheaper than ER visit or crushed vehicle.
Door Off Track
Why Dangerous: Door not properly supported by tracks. Can fall without warning (200-400 lbs). Attempting to force back on track often makes worse.
Professional Approach: Secure door safely, identify cause (broken cable, roller, impact damage), repair underlying issue, safely return to track.
Emergency Service: Available same-day. DO NOT operate door off track under any circumstances.
Track Alignment/Replacement
Why Risky: Requires precise measurements, proper support of heavy door, understanding of spring tension effects on tracking.
Professional Tools: Levels, measurements, proper brackets, knowledge of building codes and clearances.
Result of Bad DIY: Door binds in tracks, springs break prematurely, safety features compromised, door can derail.

Call Professional If: Not comfortable with electrical, working alone, door balance questionable, need permit/inspection. Cost: varies installed (vs. varies DIY parts).
Panel Replacement
DIY Difficulty: Hard. Requires removing springs/cables safely, disassembling door sections, reassembling with proper alignment.
When DIY OK: Top panel only (doesn't affect cables), have proper tools and help, door will be disconnected during replacement.
