Problems guides

Symptoms first, quotes second

Most expensive garage door repair mistakes start with a symptom described to a salesperson. The table maps the common symptoms to their usual cause — the diagnosis a contractor should confirm before quoting.

Symptom	Usual cause
Broken spring	Loud bang, door heavy
Snapped cable	Door crooked or stuck
Off track	Roller out of the channel
Opener not responding	Remote, sensor or logic board
Reversed sensors	Door closes then reopens
Noisy door	Rollers, hinges or balance

What to document

• Photographs with something for scale, taken at the same angle over time.
• Dates: when it started, whether it changes with weather.
• Water: where it goes, where it pools, what it damages.
• Previous work: who did it, when, and with what material.

What not to do first

Do not accept a repair scope before the cause is named. Patching a symptom is how the same problem returns next season with a bigger invoice. The methods hub explains what each fix addresses; the cost hub shows what it should cost.

When is it an emergency?

When water is entering the structure, when something is structurally unstable, or when a safety system has failed. Everything else can wait for a second opinion.

Should I get an independent inspection?

For anything structural or over about $5,000, yes. A few hundred dollars for an independent report is cheaper than a wrong scope.
