Should both springs be replaced if only one fails?
For a garage door that uses two springs, replacing both at the same visit is often the practical choice when the springs were installed together and have handled the same number of door cycles. The second spring may still look intact, but it has usually shared the same wear. Clopay and the Door & Access Systems Manufacturers Association both advise replacing both springs on a two-spring door when one fails.
That guidance is a starting point, not permission to order a pair by sight. A technician still needs to confirm the door weight and height, spring system, connected hardware and the correct replacement specification. Some doors use springs that differ from each other, and a prior conversion or repair can change what belongs on the system.
A pair replacement often fits
Both springs were installed together, have shared the same service life, and the rest of the counterbalance system supports a matched replacement plan.
The system needs a fresh evaluation
Spring history is unknown, the door was modified, the existing springs appear mismatched, or cables, drums, bearings, tracks or sections also show a problem.
What the Rocklin project record confirms
Public project #295 records a two-spring replacement in Rocklin on October 18, 2026. The approved summary says both garage door springs were replaced and the new springs were installed to get the door working again. Its two approved photos show replacement spring hardware and the installed spring system.
The record does not say which spring failed first, how old the springs were, their measurements or cycle rating, or which tests led to the repair decision. Those details are not inferred here. The completed scope supports one factual point: this Rocklin job received two replacement springs.
Why a two-spring door is treated as one lifting system
The springs counterbalance the weight of the door so it can move through the opening without relying on the opener to carry that load. On a two-spring system, both springs contribute to that work. If one breaks, the remaining spring is not a complete substitute for the pair, and the door can become very heavy or uneven.
A replacement plan must match the actual door. Door weight, height, spring type, drum and cable arrangement, and the complete hardware configuration all matter. Two replacement springs do not automatically need identical dimensions, and copying the visible old parts can repeat an earlier mismatch. Correct selection comes from measurements and the system requirements.
What should be checked before the repair is approved?
A spring decision should follow an inspection of the connected lifting system, not a spring-only glance. The goal is to identify what the door requires and whether another condition would make a simple pair replacement incomplete.
- Confirm the spring type and number of springs used by the door.
- Account for the door size, construction and actual lifting requirements.
- Inspect cables, drums, bearings and mounting points without loosening tensioned parts.
- Look for crooked sections, damaged tracks, worn rollers or other resistance.
- After the door is correctly balanced, check opener operation and required safety controls.
Warning signs that mean stop using the door
Stop cycling the door if you hear a sudden bang and see a gap in a spring, if the door becomes unusually heavy, if a lift cable is loose or frayed, or if the door sits crooked in the opening. Repeated opener attempts can add strain without solving a counterbalance problem.
Do not wind, unwind, cut or remove springs. Do not loosen cable drums, bottom brackets or cable attachments. If the door may be unsupported or has a broken spring, do not pull the opener release and attempt to move it alone. Amarr and Raynor both warn that spring and counterbalance work involves high tension and belongs with a qualified garage door professional.
What to send when requesting spring service
From a safe distance, send one wide photo of the full inside of the closed door and a clear photo of the spring area. Mention whether the door is stuck open or closed, whether it sits crooked, and whether you heard a bang. Do not stand beneath an unsupported door to take a photo.
