When a door has two springs and one fails, the condition and specification of the whole counterbalance system matter. DASMA recommends replacing both springs in a two-spring arrangement when one breaks. Have a trained technician assess the actual door and proposed replacement.
Identify what is installed before comparing quotes
A one-spring door and a two-spring door are different arrangements. Tell the technician if you can see a broken coil from a safe distance, but do not climb beside or handle the hardware. An estimate should make clear which system is being repaired.
Ask what the proposed pair includes
Have the number of springs, selected cycle option and associated service stated in the quote. If previous work changed the system, mention it. The useful question is whether the replacement is correctly selected for this door, not whether the new coils look identical to the old ones.
Keep the door out of service until assessed
Do not use the motor or another person’s lifting effort to compensate for the failed spring. Mention a trapped vehicle when calling. Jack’s can discuss the repair scope and price before you approve work.
Frequently Asked Questions
Does every garage door need two springs?
No. The correct arrangement depends on the door and specified system. A one-spring design is not automatically evidence of a missing part.
Can the unbroken spring prove the door is safe to operate?
No. A failed spring changes the system’s condition. Keep clear and arrange professional service.
