Garage Door Cable Snapped? What to Do Next

If your garage door cable has snapped, stop using the door. Do not press the remote again, lift the door by hand or pull the emergency release. Keep people and pets clear of the opening, particularly if the door is hanging unevenly or is partly open.

If the operator's normal power switch is safely reachable without going beneath or close to the door, switch it off. Battery-backed systems may still operate. Keep controls out of use and tell others not to operate the door. Arrange a garage door engineer to inspect it.

Has the cable snapped, or has something else failed?

A garage door's lifting cables are part of its counterbalance system. A damaged cable, failed spring or problem with the cable's routing can leave the door unsafe. You do not need to identify the exact part before asking for help.

From a safe distance, note what you can already see. Do not move the door to reproduce the fault.

A loose cable does not, by itself, prove that the cable has broken. The spring, cable and other lifting components need checking together. See our snapped spring guide if you can see spring damage, or the door-will-not-open guide for other symptoms.

Can you close a garage door with a broken cable?

Do not try to force it closed. That includes asking someone to hold one side while you move the other, using the motor to pull it straight, or propping it up to reach beneath it. Leave it in its current position and keep the opening clear until an engineer can make it safe.

Do not rely on the operator or a safety catch to support a damaged door. Garador's canopy-door instructions warn that cable and spring damage can cause serious injury and that a door whose anti-fall safeguard has operated needs specialist repair. Switching off the electricity does not release spring tension.

If the door is open and the garage cannot be secured, explain that when you call. Do not walk or drive underneath it to retrieve belongings.

What does a professional cable repair involve?

The engineer first needs to make the door safe and establish why the cable failed or came loose. The inspection should cover the other lifting components as well as the visible damage. A replacement cable alone will not resolve a separate fault elsewhere in the mechanism.

The repair depends on the door's make and mechanism. Ask the engineer to explain:

• Which components are damaged and which can remain in service.
• Whether one cable or a matched pair is specified for this repair.
• Whether there is additional spring, roller, track or fixing damage.
• How the door's balance, movement and safety functions will be checked before it is used again.

Hörmann's sectional-door maintenance instructions treat cables, springs, tracks and supports as parts of the same inspection. The correct repair follows the instructions for your particular door; there is no universal cable kit or adjustment that suits every mechanism.

How much does garage door cable repair cost?

A cable-only repair and a repair involving a spring, damaged track or distorted door are different jobs. The make, replacement parts and the work needed to secure and repair the door affect the quote.

Our garage door repair cost guide gives the existing guide prices for common repairs. Ask for a price for your diagnosed fault, including parts, labour, call-out and VAT, before authorising the work. A parts-only cable price online does not tell you the total cost of a professional repair.

A cable fault does not automatically mean replacing the whole door. Ask whether a safe repair is practical, whether suitable parts are available and what other damage has been found before comparing repair with replacement.

What to have ready when you book

• Your postcode and whether the door is open, closed or stuck partway.
• The door type: for example, one solid up-and-over panel or separate sectional panels.
• The make or model, if you already have it in your paperwork.
• Whether the door is manual or electric, and whether the garage has another entrance.
• Any photographs you can take from a safe position, without moving the door or going underneath it.

Keep the photographs ready to share when the team responds. A wide view of the door's position is useful; there is no need to get close to a damaged cable for a detailed photograph.

Tell us what has happened and request a repair callback. You can also read about Wolverine's garage door repair and maintenance service.

Frequently asked questions

Can I use the door if only one cable has broken?

No. Stop using it, keep clear and arrange an inspection. One intact cable is not a reason to operate an uneven or damaged door.

Can I put a loose cable back myself?

No. The cable may be loose because another component has failed, and the mechanism can still store energy. Leave cable replacement, repositioning and tension adjustments to a garage door engineer.

Should both garage door cables be replaced?

The engineer should inspect both sides and follow the door manufacturer's requirements. Ask whether a matched pair is appropriate for your door and what is included in the quote.
