You Heard a Loud Bang
A torsion spring can release suddenly when it breaks. The sound may be the first indication of a problem, even if nobody was operating the door at the time.
Heard a sharp bang from the garage, found the door suddenly too heavy to lift, or watched it move only a few inches before stopping? A failed spring can leave the door without the counterbalance it needs to move normally.
Garage door springs and the hardware connected to them are under significant tension. Do not loosen, remove or attempt to wind a spring yourself. If the door is open, crooked or unstable, keep people clear of the opening and arrange professional service.
A spring problem can resemble an opener problem at first. These symptoms are useful clues, but the spring and related lifting hardware should be assessed together before deciding what needs to be replaced.

The spring system counterbalances much of the door's weight. When that assistance is lost, the door can become difficult or unsafe to move.
An opener that strains, stops or moves the door only slightly may be reacting to a counterbalance problem rather than an opener motor failure.
On some torsion systems, a snapped spring leaves an obvious separation in the coil above the garage door. Inspection should be visual only; do not touch or adjust the spring.
Uneven travel may involve a spring, cable, drum, track or another part of the lifting system. Stop operating a visibly crooked or unstable door until the cause is identified.
The spring is part of the door's counterbalance system. It offsets much of the door's weight so the door can move in a controlled way and an automatic opener does not have to lift the full weight by itself.
That is why a broken spring often shows up as a door that suddenly feels much heavier, stops moving normally or causes the opener to struggle.
Homeowners do not need to diagnose or work on the spring themselves, but knowing the broad system type can make the initial service conversation clearer.
A torsion spring system is typically positioned above the garage-door opening. The spring twists as the door operates and works with the shaft, drums and cables to counterbalance the door.
A broken torsion spring may leave a visible gap in the coil. Do not touch the spring or nearby hardware to confirm the diagnosis.
Extension springs are generally positioned alongside the horizontal tracks and stretch as the door moves. These systems use different hardware and require a different service approach from torsion systems.
Extension-spring systems should also be assessed for their associated safety cables and lifting hardware.
Delta includes North Delta, Ladner and Tsawwassen, so it is better to assess the actual garage than assume every property faces the same conditions.
Usage remains a major part of spring wear. On more exposed properties, visible corrosion on springs or other metal hardware is another reason to have the full lifting system inspected rather than focusing only on the broken component.
View all Delta garage door servicesFixing a spring problem should restore the door's counterbalance rather than simply make the opener move again. The surrounding lifting system should be considered as part of the diagnosis.
Identify whether the door uses torsion or extension springs and whether the system has one, two or another spring arrangement.
Replacement springs need to suit the door's weight and counterbalance setup rather than being selected by appearance alone.
Related lifting hardware should be checked for wear, damage or another condition that may affect safe operation.
Once spring work is complete, the door should be correctly counterbalanced rather than relying on the opener to overcome excess weight.
Tracks, rollers and movement should be reviewed so a separate binding or alignment issue is not mistaken for a spring-only problem.
After the door is mechanically balanced, the opener can be assessed under normal load to determine whether any separate opener problem remains.
A useful quote needs the actual spring system and door information. Publishing one universal spring-repair price would ignore important differences between doors.
Photos can help with the initial conversation, but final spring selection should be based on the door and its counterbalance requirements.

Clear answers to the questions homeowners commonly have after a door suddenly becomes heavy, stuck or difficult to operate.
Common signs include a loud bang from the garage, a door that suddenly feels unusually heavy, a visible separation in a torsion spring, uneven movement or an opener that lifts the door only a short distance. Do not touch or adjust the spring to confirm the problem.
Avoid repeatedly operating a door that may have a failed spring. Without proper counterbalance, the door can be much heavier and less predictable than normal. If it is open, partly open or crooked, keep people clear and arrange professional service rather than attempting to force it.
Garage door spring replacement is not a suitable DIY repair. Springs, cables and related hardware can be under substantial tension, and incorrect handling can result in serious injury or an uncontrolled door movement.
Not usually by itself. A failed spring is a component problem and does not automatically mean the entire garage door requires replacement. The door, hardware and counterbalance system should be assessed before making that decision.
It depends on the spring arrangement, age, condition and specification of the system. On a two-spring setup, the remaining spring should be evaluated rather than automatically assuming either that it must stay or that it must be replaced.
Yes. Opener faults can produce some similar symptoms, but a failed spring can also make a working opener strain or stop. The door's mechanical balance should be established before assuming that the opener itself needs replacement.
Cost depends on the spring system, door configuration, number and specification of springs, and whether related hardware also needs service. A quote should explain what parts and work are included rather than relying on a single generic spring-repair price.
Share your Delta location, what happened immediately before the problem appeared, whether the door is open or closed, any loud bang you heard, how the door is sitting now, and safe photos taken from a distance. Do not move or handle damaged spring hardware to get a better picture.
Tell us what happened, whether the door is open or closed, and whether you heard a snap or bang. If it is safe to do so, include photos taken without touching the spring, cables or other damaged hardware.
