Frequently Asked Questions

What Are Garage Door Springs and Why Do They Break?

Garage door springs are the workhorses of your garage door system. These tightly wound metal coils counterbalance the weight of your door—which can be anywhere from 50kg to 150kg—making it possible to lift manually or with a motor.

Why springs eventually fail:

Metal fatigue: Every time your door opens and closes, the springs flex. After thousands of cycles, the metal weakens
Corrosion: Moisture in Auckland's humid climate causes rust, particularly in coastal areas
Temperature fluctuations: Metal contracts and expands, weakening the molecular structure
Improper tension: If springs were incorrectly installed or adjusted, they wear unevenly
Manufacturing defects: Lower-quality springs have shorter lifespans

Most spring failures happen suddenly—you'll often hear a loud bang when a spring snaps, typically while the door is closed (when springs are under maximum tension).

How Do I Know If My Garage Door Spring Is Broken?

Clear signs of a broken spring:

Loud bang: The most obvious sign—sounds like a gunshot or firework
Door won't open: Manual operation is impossible or extremely heavy
Door opens partially then stops: Opener can't lift the full weight
Visible gap in spring: You can see where the coil has separated
Door closes too quickly: Without spring tension, gravity takes over
Opener motor strains: You hear grinding or the motor cuts out
Cables hanging loose: Extension spring systems show slack cables

Visual inspection checklist:

Component	What to Look For	Action Required
Torsion spring	Gap or separation in coil	Immediate replacement
Extension springs	Stretched, rusty, or hanging loose	Schedule replacement
Spring ends	Rust, fraying, or damage	Replace soon
Cables	Frayed, kinked, or broken strands	Professional inspection

⚠️ Safety Warning: Never attempt to open or close a door with a broken spring. The unbalanced weight can cause the door to fall, potentially causing severe injury or property damage.

What's the Difference Between Torsion Springs and Extension Springs?

Understanding your spring type helps you communicate with repair professionals and understand cost differences.

Torsion Springs

Location: Mounted horizontally above the door opening Function: Twist to store energy, unwinding as door opens Common on: Sectional garage doors, newer installations Lifespan: 15,000-30,000 cycles (10-15 years with average use) Advantages:

Smoother operation
Better weight distribution
Longer lifespan
Safer failure mode (stays on shaft)

Cost: $220-$450 installed

Extension Springs

Location: Mounted along the horizontal tracks on each side Function: Stretch and contract to lift the door Common on: Tilt doors, older sectional doors, lighter doors Lifespan: 10,000-15,000 cycles (7-10 years) Advantages:

Lower initial cost
Simpler design
Easier to retrofit

Cost: $180-$320 installed (pair)

Can I Replace Garage Door Springs Myself?

Short answer: We strongly recommend against DIY spring replacement.

The Dangers of DIY Spring Replacement

Garage door springs store enormous amounts of energy—enough to lift 70-150kg. When that energy releases unexpectedly:

Documented injuries from DIY spring replacement:

Broken bones (fingers, hands, arms)
Severe lacerations
Facial injuries from springs breaking loose
Crushed fingers from door collapse
At least 3 fatalities in New Zealand between 2010-2023

The New Zealand Accident Compensation Corporation (ACC) receives 50-70 garage door injury claims annually, with spring-related incidents among the most severe.

Why Professional Replacement Matters

Specialized tools required:

Winding bars (specific size for your spring)
Proper safety equipment
Torque wrenches for precise adjustment
Door weight calculation tools

Technical knowledge needed:

Calculating correct spring tension
Proper winding technique (30-40 quarter turns typically)
Cable routing and tensioning
Balance adjustment
Safety inspection protocols

Legal and insurance implications:

DIY spring replacement may void your door warranty
Insurance claims may be denied if injury occurs during DIY repair
If door falls and damages vehicles/property, liability issues arise

When DIY Maintenance IS Appropriate

You can safely:

Lubricate springs (spray-on silicone lubricant every 3 months)
Tighten loose hardware (hinges, track bolts)
Clean photo-eye sensors
Replace remote batteries
Manually test door balance (with springs intact)

How Long Do Garage Door Springs Last?

Spring lifespan is measured in cycles (one complete opening and closing = one cycle).

Expected Lifespan by Spring Type

Torsion Springs:

Standard 10,000-cycle springs: 7-10 years (average use)
High-cycle 20,000-30,000 springs: 15-20 years
Commercial/heavy-duty springs: 50,000+ cycles

Extension Springs:

Standard springs: 10,000-15,000 cycles (7-12 years)
Heavy-duty extension springs: 20,000 cycles (12-15 years)

What "Average Use" Means

Calculating your usage:

Average household: 3-5 cycles per day = 1,100-1,800 cycles/year
High-use household: 8-10 cycles per day = 2,900-3,600 cycles/year
Single person/low use: 1-2 cycles per day = 365-730 cycles/year

Example: If you have 10,000-cycle springs and use your door 4 times daily:

Annual cycles: 4 × 365 = 1,460 cycles
Expected lifespan: 10,000 ÷ 1,460 = 6.8 years

How Much Does Garage Door Spring Replacement Cost in Auckland?

What Affects Spring Lifespan in Auckland Homes?

Several environmental and usage factors influence how long your springs last:

1. Coastal Proximity

Salt air corrosion is the biggest factor affecting Auckland garage door springs:

Beachfront properties (0-500m from ocean): Springs may last only 3-5 years
Coastal suburbs (500m-2km): 5-8 years typical
Inland areas: Full 10-15 year lifespan possible

Protective measures:

Powder-coated or galvanized springs add 30-50% to lifespan
Regular cleaning and lubrication helps
Consider enclosed track systems for extreme coastal exposure

2. Humidity and Weather Exposure

Auckland's average humidity of 75-80% accelerates rust formation:

Garages with poor ventilation see faster deterioration
Doors facing prevailing weather (west/southwest) rust faster
Condensation in uninsulated garages speeds corrosion

3. Door Weight and Insulation

Heavier doors = more spring strain:

Non-insulated steel sectional: ~60-80kg
Insulated sectional: ~80-110kg
Cedar or timber doors: ~100-150kg
Double-skin insulated: ~120-180kg

Springs sized incorrectly for door weight fail prematurely.

4. Maintenance Frequency

Well-maintained springs last 40-50% longer:

Lubrication every 3 months: Reduces friction and rust
Annual professional service: Catches early wear signs
Immediate corrosion treatment: Prevents accelerated failure

5. Opener Quality and Settings

Poor opener adjustment causes premature spring failure:

Excessive force settings: Opener works against springs
Limit switch problems: Door over-travels, stressing springs
Worn opener gears: Creates jerky movement

How Can I Make My Springs Last Longer?

Proper maintenance can extend spring life by 3-5 years:

Quarterly Maintenance (15 minutes)

Every 3 months:

Visual inspection
- Look for rust, gaps, or separation in coils
- Check for cable fraying or slack
- Examine rollers for wear or damage
Lubrication
- Use silicone-based garage door lubricant (not WD-40)
- Spray along full length of springs (both sides if extension springs)
- Lubricate rollers, hinges, and bearings
- Wipe away excess to prevent dust buildup
Balance test
- Disconnect opener (pull emergency release cord)
- Manually lift door to hip height
- Release—door should stay in place or move slowly
- If door falls quickly or shoots up, springs need adjustment

Annual Professional Service

A professional service ($120-$180) includes:

Complete door balance adjustment
Spring tension calibration
Cable inspection and tension check
Track alignment verification
Roller and hinge inspection
Opener force adjustment
Safety reverse testing
Complete lubrication

Protection for Coastal Properties

If you're within 2km of the coast:

Upgrade to coated springs: Powder-coated or galvanized springs cost 20-30% more but last 50% longer in coastal conditions
Monthly rinse: Hose down door and springs to remove salt buildup
Apply corrosion inhibitor: Specialty products like Lanolin-based sprays
Improve ventilation: Install vents to reduce condensation
Consider enclosed tracks: Protects springs from direct salt exposure

What Happens During Professional Spring Replacement?

Understanding the process helps you know what to expect:

1. Initial Assessment (10-15 minutes)

The technician will:

Confirm spring failure (visual inspection)
Weigh or calculate door weight
Measure spring dimensions (wire size, inside diameter, length)
Check cable condition
Inspect rollers, hinges, and tracks
Test opener functionality
Provide quote for parts and labor

2. Safety Preparation (5 minutes)

Door is fully lowered and secured
Opener is disconnected
Area is cleared of people and pets
Protective equipment is worn
Tools are staged

3. Spring Removal (15-20 minutes)

For torsion springs:

Old spring is unwound using proper winding bars
Tension is fully released (requires precision)
Set screws are loosened
Spring is slid off torsion shaft
Bearings and shaft are inspected

For extension springs:

Door is secured in open position
Tension is released from pulley system
Safety cables are removed
Springs are unhooked from track brackets
Cables are inspected for fraying

4. Installation of New Springs (20-30 minutes)

Correct spring is selected (matched to door weight)
Spring is positioned on shaft (torsion) or mounted to bracket (extension)
Set screws are tightened to manufacturer specifications
Spring is wound to correct tension (30-40 quarter turns typical for torsion)
Cables are routed and tensioned
Safety cables are installed (extension springs)

5. Adjustment and Testing (15-20 minutes)

Door balance is tested and fine-tuned
Manual operation is verified
Opener is reconnected and tested
Force settings are adjusted if needed
Safety reverse feature is tested
All moving parts are lubricated
Final inspection is completed

6. Warranty Documentation (5 minutes)

Parts warranty is explained (typically 1-3 years)
Labor warranty is confirmed (typically 1 year)
Maintenance recommendations are provided
Documentation is provided

Total time: 60-90 minutes for standard single door spring replacement

Do I Need to Replace Both Springs at Once?

For extension springs (paired system): YES, always replace both sides.

Even if only one spring has broken, the other spring:

Has experienced the same number of cycles
Is under the same environmental conditions
Is made from the same batch of materials
Will likely fail within weeks or months

Replacing just one side creates:

Imbalanced door operation: Causes binding and premature wear
Additional service call costs: Second spring breaks soon after
Safety hazards: Uneven lifting can damage opener or cause door to jam

For torsion springs (single or dual systems):

If your door has one torsion spring that breaks, you're replacing the only spring—no choice needed.

If your door has two torsion springs (common on heavy double doors):

Best practice: Replace both springs for same reasons as extension springs
Budget option: Can replace only the broken spring if second spring is relatively new (<3 years old)
Risk: Second spring may fail within 6-12 months

Professional recommendation: Replace both springs simultaneously. The price difference is minimal:

Single spring replacement: $220-$320
Both springs: $280-$400 (only $60-$80 more)
Saves a second service call ($120-$150 trip charge)

Are There Different Quality Levels of Springs?

Yes—spring quality varies significantly, affecting both performance and lifespan:

Spring Quality Tiers

Standard (Economy) Springs

Cycle rating: 10,000 cycles
Expected lifespan: 5-8 years (average use)
Wire coating: Basic oil coating or painted
Warranty: 1 year parts
Cost: Lowest (included in basic replacement)
Best for: Budget-conscious homeowners, rental properties

High-Cycle Springs

Cycle rating: 20,000-30,000 cycles
Expected lifespan: 10-15 years
Wire coating: Powder-coated or galvanized
Warranty: 2-3 years parts
Cost: 20-40% more than standard
Best for: High-use households, coastal properties

Commercial/Heavy-Duty Springs

Cycle rating: 50,000-100,000 cycles
Expected lifespan: 20-30 years
Wire coating: Heavy galvanization or specialty coating
Warranty: 5+ years
Cost: 100-150% more than standard
Best for: Commercial properties, extreme conditions

Coating Options

Standard oil-coated: Basic protection, shortest lifespan Powder-coated: Better corrosion resistance, adds 30-40% to lifespan Galvanized: Excellent coastal protection, adds 50-60% to lifespan PTFE-coated: Premium option, best for extreme environments

Making the Right Choice

Choose standard springs if:

Budget is primary concern
Door is in low-use area (rarely opened)
Property is inland with low humidity
You're planning to replace the entire door soon

Choose high-cycle springs if:

Door is used frequently (10+ times daily)
Property is coastal (within 2km of ocean)
You want long-term investment
Previous springs failed prematurely

Choose commercial-grade if:

Door is extremely heavy (custom timber, extra insulation)
Business/rental property needs reliability
Extreme coastal exposure (beachfront)
Cost of service calls outweighs spring upgrade

Investment comparison:

Standard springs: $220 replacement every 7 years = $31/year
High-cycle springs: $280 replacement every 12 years = $23/year
Commercial springs: $400 replacement every 20 years = $20/year

The high-cycle springs often offer the best long-term value for typical residential applications.

Frequently Asked Questions

How long does spring replacement take?

Professional spring replacement takes 60-90 minutes for a standard single garage door, or 90-120 minutes for a double door or complex system.

Can I still use my garage door opener with a broken spring?

No—never attempt to use your opener with a broken spring. The motor isn't designed to lift the full weight of the door and can burn out quickly. Additionally, the unbalanced door poses serious safety risks.

Will my home insurance cover spring replacement?

Generally, no. Spring replacement is considered routine maintenance rather than damage. However, if a broken spring causes secondary damage (door falls and damages car), that damage may be covered under contents insurance.

How do I know what size spring I need?

Spring sizing requires measuring:

Wire diameter (gauge)
Inside diameter of coil
Length of spring
Number of coils

Your technician will calculate the correct spring based on these measurements plus your door's weight. Never guess—incorrect springs can cause immediate failure or safety issues.

Do springs come with warranties?

Yes, quality springs include warranties:

Parts warranty: 1-3 years typical (some premium springs offer 5-10 years)
Labor warranty: Usually 90 days to 1 year
Cycle guarantee: Some manufacturers guarantee minimum cycle ratings

Always ask about warranty terms before replacement.

Can springs be repaired instead of replaced?

No. Once a spring breaks, it must be replaced. There's no safe or effective way to repair a broken spring. Additionally, attempting to weld or splice a spring creates a dangerous weak point.

Why did my spring break in winter?

Cold weather causes metal to contract and become more brittle. Many springs fail during cold snaps because:

Metal is less flexible at low temperatures
Overnight cold causes maximum contraction
First morning use applies stress to cold, brittle metal

This is normal and doesn't indicate a defective spring.

Should I upgrade to high-cycle springs?

If any of these apply, upgrade to high-cycle springs:

Previous springs failed prematurely (<5 years)
You're within 2km of the ocean
Door is used more than 10 times daily
You plan to stay in home long-term
Cost of service calls is a concern

The additional $50-$100 cost typically pays for itself in extended lifespan.
