What does it mean when my garage door bangs loudly then won't open?
A straight answer for Broward County homeowners, then what you can check yourself and when to call. Free estimate: (954) 906-1715.
A loud bang followed by a door that won't lift most often means a torsion spring (or, less often, a lifting cable) has snapped. The springs carry nearly all of the door's weight, so once one breaks, the opener motor can't raise the door on its own.
The same bang can also come from a cable slipping off its drum, a roller or hinge breaking, or a section of track bending. Whichever it is, stop pressing the opener button and keep the door from being moved until it has been looked at.
Why it happens
A garage door is heavy, and the springs store the energy that balances it. Every open and close cycle flexes them. Over time the metal fatigues and eventually lets go all at once, which is the bang. Broward's heat and humidity speed this up, and in coastal neighborhoods salt air corrodes springs, cables and hardware, which weakens them further.
When the spring is gone, the opener is asked to lift the full weight of the door. Motors aren't built for that, so the door stays shut or rises a few inches and stops. Pressing the button repeatedly can strain the opener, bend the door, or pull a cable off its drum.
This matters beyond convenience. The garage door is usually the largest opening in a home. A door with failed or mismatched hardware isn't performing the way it was designed to, and in a strong wind a weakened door can be the opening that gives way first.
What you can check yourself
Stop using the opener
Don't keep pressing the button or the remote. Repeated attempts against a door with no spring can damage the opener, cables and panels.
Look, don't touch
From a safe distance, look at the spring on the bar above the door. A visible gap in the coil, or a door that looks crooked or off its track, points to a mechanical failure.
Check the wall control lock
Many wall controls have a lock setting that stops the remotes and the opener from responding. If the bang was something else and the door simply won't respond, confirm that lock isn't on.
Don't try to lift the door by hand
Without a working spring the door can be very heavy and can drop suddenly. Don't use the emergency release cord on a door that is partly open either. Keep people, pets and vehicles clear.
Note what you heard and saw
Was it one sharp crack from above the door, or a scraping and clanging along the sides? Tell the technician; it helps narrow down the cause before they arrive.
When to call a pro
Springs and cables are under high tension and are a call-a-pro item. Don't try to adjust, unwind or replace them yourself. Call us at (954) 906-1715 for any bang followed by a door that won't open, a door stuck partly open, or one that looks off its track.
Garage door work in Broward falls under the Broward County Certificate of Competency that covers garage doors, which we hold as 20-WD-21968-X. Florida has no widely recognized standalone statewide garage door license, so confirm licensing for your scope with DBPR, the Broward County Central Examining Boards or your city's building department. Spring and hardware repairs may not need a permit, but replacing the door generally does. Verify with your city's building department, and with your HOA or condo board if one applies.
Impact Garage Doors work is done under Broward County Certificate of Competency 20-WD-21968-X (windows, doors, shutters & garage doors).
What a pro will do
- Find the actual failureWe check springs, cables, drums, rollers, tracks and panels, plus the opener, because a broken spring often isn't the only damaged part.
- Repair springs, cables and rollersFailed springs and worn cables are replaced and the door is rebalanced so it lifts smoothly and the opener isn't carrying the load.
- Fix tracks and panelsBent tracks or cracked panels are repaired or replaced so the door runs true again.
- Repair or replace the openerIf the opener was strained by repeated attempts, we repair it or replace it.
- Advise on replacement if the door is past repairIf the door is badly damaged or isn't wind-rated, we can quote a replacement with an HVHZ-approved product, pull the permit, schedule inspections and close out the permit.
Related questions
- Does a broken spring mean I need a new garage door?
- Not necessarily. Springs are a wear item and are routinely replaced on an otherwise sound door. If the door is also damaged, corroded, or is an older model with no wind rating, replacing it may make more sense. We'll tell you which applies at the free estimate.
- Do I need a permit to repair a garage door spring?
- Operator-only, spring and hardware repairs generally may not need a permit, while replacing the door generally does because the door and its track anchorage are part of the building envelope. Rules differ by city, so verify with your city's building department.
- What does a replacement door need to meet in Broward?
- Broward is in the High-Velocity Hurricane Zone, so a replacement garage door needs a product approval valid for the HVHZ, usually a Miami-Dade NOA. It also needs an impact rating or approved bracing and must be anchored to the jambs and tracks as the approval specifies.
- Can an impact-rated garage door help with wind-mitigation credits?
- Approved opening protection is one category on Florida's wind-mitigation form OIR-B1-1802, which a licensed inspector completes, and it is evaluated across all openings. Florida law (s. 627.0629) requires insurers to offer discounts for wind-loss-mitigation features, but amounts vary by insurer. You can try the free Wind Mitigation Credit Checker on this site.
- Can I just wait until the door is convenient to fix?
- A stuck door can leave your garage unsecured or your vehicles trapped, and forcing it can cause more damage. It's best to have it looked at soon, especially heading into hurricane season. Call (954) 906-1715 for a free estimate.
