The full list, in the guide's words

Safety first: Never try to adjust, loosen or release a garage door spring or cable yourself. The stored tension is a leading cause of injuries in this trade. If anyone has been struck or pinned, keep everyone clear and call 911. Stay away from a door that is off its track.

Emergency: call now

  • A broken spring (a loud bang, a door that will not lift or lifts only a few inches), especially with a car trapped inside
  • A door stuck fully open that leaves the house unsecured
  • A door off its track, jammed or with a panel hanging, or a snapped cable that leaves the door hanging unevenly
  • An opener failure that has locked a car in or out before a work, school or medical trip

Within a day or two

  • A door that still works but opens crooked or jerky, grinds loudly, reverses or will not stay down
  • An opener that works intermittently, one frayed cable, or a misaligned safety sensor

Can wait: schedule it

  • Tune-ups, safety inspections, lubrication and balance checks
  • Weather seals, and remote and keypad programming
  • Quotes for a new door, an opener replacement or a damaged panel

This is general guidance, not a diagnosis. If anyone is in danger, call 911 first.

Know what you're looking at

Red flags

4 of 11

  • No spring size or cycle rating

    Low-cycle springs may need replacing sooner.

  • Whole new door for one part

    Ask why a panel or part won't do.

  • Low call price that rises

    Ask for the total before they come.

  • Told to adjust the spring yourself

    Spring tension causes injuries.

7 more red flags

  • Pressure to sign today, or a price that is only good right now.

    A fair quote is still fair tomorrow.

  • No written quote, or a quote that is a single total with no detail about what is included.

  • A large payment up front, or a request for cash only.

    Some states limit how much a contractor can ask for before work starts.

  • A license number that does not check out.

    Where your state licenses this trade, look the number up yourself on the state licensing board's site.

  • No proof of insurance.

    Ask for a certificate sent to you directly by the insurer or the agent.

  • A price far below every other quote, followed by extras once the work has started.

  • Someone who knocks on your door uninvited, or who will not give recent local references.

Where homeowners say it goes wrong

  • Their car is trapped or the house is left unsecured and they need someone today, not next week
  • They're afraid to touch a broken spring (rightly — it's dangerous) and need a pro fast
  • They got a surprise repair quote and don't know if a spring or opener price is fair
  • Their old door keeps breaking and they don't know whether to keep fixing it or replace it
  • Past companies no-showed, gave vague arrival windows, or did unsafe spring work

Ask every garage door company

  1. What spring type, size and cycle rating are you installing, and is it matched to my door's weight?

  2. Are you replacing related worn parts (cables, rollers) at the same time, and what is the price with and without them?

  3. Does the work include checking the balance, the auto-reverse feature and the safety sensors?

2 more questions

  1. Are you licensed where this work requires it, and insured? Can I see the license number and a certificate of insurance sent to me by your insurer?

  2. What exactly does the warranty cover, for how long, and who honors it (you, the manufacturer, or both)? Will you put it in writing?

Permits

This work rarely needs a permit, although exceptions exist when it touches structure, electrical, plumbing or gas.

Rarely. Replacing parts or an opener normally needs no permit. A new door in a different size, or changes to the structure, may need one, and some HOAs regulate how a door looks.

  • Your building department decides what applies at your address. Rules differ by city and county, and HOA, condo or historic-district rules can add more.
  • Ask who pulls the permit. Normally the licensed contractor does and the price includes it. If a contractor asks you to pull it in your own name, ask why: it can shift responsibility for the work to you.
  • If you are unsure, call your local building department before you sign. Unpermitted work can cause problems with insurance and when you sell.

Paying for it

Before you finance anything6 basics, then the financing guide

Most home projects can be paid in cash or financed. A few basics before you sign anything:

  • Ask for the cash price and the financed price in writing, for the same scope of work. They can differ, because a financing fee (sometimes called a dealer fee) may be built into the financed price.
  • Compare the total you will pay over the whole loan, not just the monthly payment.
  • Read the fine print on same-as-cash and zero-interest offers, especially what happens if the balance is not paid in full by the end of the promotional period.
  • PACE financing is repaid through your property tax bill and can place a lien on your home. Read the terms closely, and consider asking your mortgage servicer how it is treated, before you agree.
  • Utility and state programs sometimes offer low-rate loans for efficiency work. Check yours before accepting the contractor's offer.
  • Take loan paperwork home and read it. A sign-it-today loan is a reason to slow down.
