If one spring snaps, stop using the opener and keep people clear of the door. On a two-spring setup, the main question is whether to replace only the broken spring or both springs together. A technician handling garage door spring repair in Vancouver should first confirm your spring system, door balance, and the condition of the second spring before you approve the work.
Quick overview
- The door suddenly feels much heavier than normal.
- One torsion spring has a visible gap in the coil.
- The opener strains, hums, or will not lift the door.
- You were quoted for two springs but only one looks broken.
In this guide
- Ask for the spring count, spring type, parts, labour, and warranty in writing.
- Do not approve extra parts unless the technician explains why each one is needed.
Simple version:
- Two-spring system with one failed spring: ask about replacing both.
- Single-spring system: only one spring is there to replace.
- Do not run the opener to test a door with a broken spring.
- Get the total price before work starts.
TL;DR: One Spring or Both?
- For a two-spring system, replacing both is often recommended because the springs share the same use.
- If the second spring is newer, ask the technician to show you its condition and explain the recommendation.
- The quote should separate parts, labour, extra hardware, tax, and any after-hours fee.
What a Broken Garage Door Spring Means
Garage door springs help carry the door’s weight. When one breaks, the opener may no longer lift the door safely. If your system uses torsion springs, a technician may discuss torsion spring replacement instead of trying to keep an old matching spring in service.
Context (what matters in this situation):
- A visible gap in a torsion spring is a common sign that it has broken.
- The door may feel too heavy to lift by hand.
- The opener is not designed to replace the lifting force of a broken spring.
- Spring size should match the door, not just the old spring’s look.
Why a Technician May Recommend Replacing Both
On a two-spring door, both springs work every time the door opens and closes. If one fails, the second spring may be near the same wear point, especially if both were installed at the same time. A proper visit should also check nearby parts such as garage door cables and garage door rollers for damage caused by an unbalanced door.
What this usually looks like (real-world flow):
- One spring breaks and the door becomes hard to lift.
- The technician confirms whether the door has one spring or two.
- They identify the spring type and match it to the door.
- They inspect the second spring and the lifting hardware.
- You approve the exact scope and price before replacement.
Details to confirm (so you get the right help fast):
- Ask whether both springs were installed at the same time.
- Ask whether both new springs will be the same matched pair.
- Ask what balance test will be done after the repair.
What you should get as the outcome:
- The door should move smoothly after the repair.
- The opener should not have to fight a badly balanced door.
- You should know exactly which parts were replaced.
Quote Limits and Hidden Costs to Check
Do not assume the first number you hear is the final bill. Use this guide to confirm garage door repair fees before dispatch or before work starts, especially if the call is after hours.
Limits / constraints (what can slow things down):
- The quote may cover one spring only, not a matched pair.
- A service-call fee may be separate from labour.
- Warranty terms may differ for parts and labour.
- Extra hardware should be listed before it is installed.
Hidden costs to watch for:
- After-hours or emergency dispatch fee.
- Second spring or upgraded spring pair.
- Cable, bearing, drum, or bracket work if damage is found.
- Tax or disposal charges if they are not already included.
What to Do Before You Approve the Repair
Ask for a written scope before the technician starts. This residential garage door repair quote checklist can help you confirm what should be included and what questions to ask.
- Confirm whether the price is for one spring or two.
- Confirm the total with labour, fees, warranty, and tax.
Our Recommendations Before You Replace a Spring
Do not lift or close a heavy door by force.
Confirm whether your door has one spring or two.
If two springs were installed together, ask for the price of a matched pair.
Ask the technician to explain any extra part before replacing it.
Ask for the warranty terms in writing.
Keep the final invoice for future service history.
Safety Steps While the Spring Is Broken
If the door is stuck, treat the spring as a high-tension part and keep clear of it. If the door blocks your car or will not close, ask about emergency garage door repair in Vancouver instead of trying to wind or remove a spring yourself.
A good option is:
- Stop using the automatic opener.
- Keep children and pets away from the door.
- Do not touch the spring, cable, drum, or bottom bracket.
- Do not pull the emergency release while the door is raised unless a trained technician says it is safe.
- Wait for a trained door technician to inspect the system.
Scenario 1: One of Two Springs Broke
If one spring broke and the door also twisted or jumped in its tracks, ask the technician to inspect the track before cycling the door. Separate garage door track repair should only be added if the track is bent, loose, or damaged.
Do this:
- Confirm both springs are the same system.
- Ask whether the second spring is the same age.
- Get the one-spring and two-spring scope clearly stated.
Scenario 2: The Opener Was Used After the Spring Broke
If the opener kept trying to lift the door after the spring failed, tell the technician what happened. They can check whether the opener was strained and whether separate garage door opener repair is actually needed.
We recommend this:
- Stop pressing the wall button or remote.
- Tell the technician if the opener hummed or stopped.
- Do not approve a new opener unless it is tested after the spring repair.
Scenario 3: Other Hardware Looks Damaged
A broken spring can expose other wear, but every extra repair should have a reason. If a hinge is cracked or pulling away from the section, ask for a separate line item for garage door hinge replacement instead of a vague hardware charge.
Here’s a simple path forward:
- Ask to see the damaged part.
- Ask whether the part affects safe door movement.
- Approve only the work you understand.
Suggested plan:
Step 1: Get the Scope Before Dispatch
Tell the company that one spring appears broken and ask what the visit fee covers. Before booking, review these garage door estimate upsell red flags so you know when to ask for a clearer explanation.
Step 2: Share the Door Details
Send the address, a photo of the spring system, the door size if known, and whether the car is trapped. This can help the technician bring the right parts, but the final spring choice should be confirmed on site.
Step 3: Confirm the Repair Options
Ask what is broken, what is worn, and what is optional. If the door section was damaged when the spring failed, keep garage door panel replacement as a separate decision from the spring repair.
DASMA Garage Door Safety Tips
The DASMA garage door safety tips explain that garage door springs wear out and note that two-spring doors should have both springs replaced if one breaks. This helps explain why a technician may recommend a matched pair instead of only the failed spring. The page also warns that spring and cable work involves dangerous tension. Use it as a safety check when you review a repair recommendation.
Frequently Asked Questions
Should I replace both garage door springs if only one broke?
If your door uses two springs and both were installed together, replacing both is commonly recommended because both have handled the same door use. Ask for the price, spring type, and warranty for the pair before you approve the work.
Can I use the garage door with one broken spring?
Do not keep running the opener to test it. The door may be very heavy or unbalanced, and the opener can be put under extra strain. Keep the area clear and arrange service.
What if my garage door has only one spring?
A single-spring system only has one spring to replace. The technician should still match the new spring to the door and check the balance after the repair.
Should sensor repair be included with a spring replacement?
Not automatically. Garage door sensor repair is a separate issue unless testing shows the sensors are damaged or misaligned. Ask for a clear reason before adding it to the spring job.
How do I know the new spring is the right size?
The spring should be selected for the door’s weight and spring system, not by looks alone. Ask the technician to explain the spring type and confirm the door is balanced after installation.
What other charges should stay separate from spring repair?
Items such as garage door weather stripping replacement should be separate unless you asked for them or they are needed for the job. Your invoice should show the spring work, labour, extra parts, fees, and tax clearly.
