Double Torsion Spring Replacement: Complete Cost & Process Guide
When one torsion spring breaks, should you replace both? The short answer: absolutely yes. This guide explains why double spring replacement is smarter, what it costs, and what to expect during the service.
💰 Smart Money Decision
Replacing both springs when one breaks costs only $75-$125 more than a single spring replacement. But it saves you from a second service call (another $75-$125 just for the visit) plus the hassle of being stranded again when the second spring inevitably breaks within months.

Why Replace Both Springs Together?
This is the question every homeowner asks when we recommend double replacement. Here's why every professional gives the same advice:
1. Both Springs Have Identical Wear
Your torsion springs were installed at the same time and have cycled together thousands of times. They've experienced the same stress, temperature changes, and metal fatigue. When one breaks, the other is essentially running on borrowed time—usually within weeks or months of failure.
2. Mismatched Springs Cause Problems
If you replace only one spring:
- Tension imbalance: New spring has full strength; old spring is weakened
- Door twisting: Uneven lift causes the door to bind in tracks
- Faster wear: The new spring works harder to compensate
- Opener strain: Motor fights against the imbalance
- Shortened new spring life: Extra stress reduces its lifespan
3. Second Service Call Economics
Let's do the math:
| Scenario | Costs | Total |
|---|---|---|
| Replace one spring now | $175-$275 | $350-$550 |
| Replace second spring later (separate call) | $175-$275 | |
| Replace both springs now | $275-$450 | |
| Savings by doing both together | $75-$100+ | |
4. One Visit, One Disruption
Beyond money, there's the convenience factor. Replacing both means:
- One day scheduling around service
- One time waiting at home
- One period with the door inoperable
- Peace of mind for years instead of months

The Double Spring Replacement Process
Here's what happens when Lemus Garage Door Services performs a double torsion spring replacement:
- Safety Setup (5 min) — We clamp the door to prevent movement, disconnect the opener, and set up safe working conditions. Never attempt spring work without these precautions.
- Tension Release (10 min) — Using professional winding bars, we carefully release tension from both springs. This is the most dangerous part—improper technique can cause serious injury.
- Spring Removal (10 min) — We unbolt the center bracket, slide off the old springs, and inspect the torsion shaft for wear or damage.
- New Spring Installation (15 min) — New springs are slid onto the shaft, positioned correctly, and the center bracket is secured. We ensure proper spring orientation (left-wound and right-wound).
- Spring Winding (15 min) — Using precise calculations for your door weight, we wind each spring to the exact tension required. For a 16x7 door, this is typically 7-8 full turns per spring.
- Cable & Hardware Check (10 min) — We inspect cables, drums, end bearings, and all hardware. Worn cables are replaced (often included in our service).
- Balance Testing (10 min) — The door is disconnected from the opener and manually tested. A balanced door stays in place at any height. We adjust spring tension until perfect.
- Opener Reconnection & Final Test (10 min) — We reconnect the opener, test full operation including safety reversing, and ensure smooth, quiet operation.
⏱️ Total Time: 45-90 Minutes
Most residential double spring replacements take about an hour. Larger doors, difficult access, or additional repairs may extend this. We always provide accurate time estimates before starting work.
Single vs Double Spring Systems
Understanding your current setup helps you know what to expect:
Two-Spring Systems (Most Common)
Most two-car garage doors (16' wide and larger) use two torsion springs mounted on a single shaft. Benefits include:
- Shared load = longer spring life
- Better door balance
- If one breaks, door may still operate (carefully) with the other
- Easier to find replacement springs
Single-Spring Systems
Some lighter doors or older installations use a single, heavier-duty spring. This is less ideal because:
- All stress on one spring = shorter life
- Complete failure when spring breaks
- Less balanced lifting
- May benefit from conversion to dual-spring
💡 Upgrade Option
If you have a single-spring system, we can often convert to dual springs during replacement. This costs an additional $50-$100 for the second spring and provides better balance and longevity. Ask about this option when scheduling.
Signs You Need Double Spring Replacement
Immediate Warning Signs (Call Now)
- Loud bang: You heard a loud pop or bang from the garage
- Door won't open: Manual or opener operation fails
- Visible gap: You can see a break in the spring coils
- Door slammed shut: Door fell or closed forcefully
- Cables slack: Lift cables are loose or off drums
Proactive Warning Signs (Schedule Soon)
- Door heavy to lift: Springs losing tension
- Opener struggles: Motor strains or runs longer
- Door crooked: One side higher than the other
- Age: Springs are 7+ years old
- Rust or wear: Visible corrosion on spring coils
- Squeaking/grinding: Springs need lubrication or are wearing
⚠️ Don't Operate a Broken Spring Door
If one spring is broken, do NOT attempt to open the door with your opener. This forces the opener to lift the entire door weight (150-250 lbs) that springs normally counterbalance. You'll burn out the opener motor and risk the door falling.
Frequently Asked Questions
Why should I replace both torsion springs at the same time?
Both springs have identical age and wear. When one breaks, the other is close behind—often within weeks or months. Replacing both saves a second service call ($75-$125), ensures matched tension for proper door balance, and prevents being stranded again. The second spring is usually only $50-$75 extra when done together.
How much does double torsion spring replacement cost?
Double torsion spring replacement typically costs $275-$450 in Katy, TX. This includes two springs ($100-$200 for the pair), labor ($150-$200), and hardware inspection. High-cycle spring upgrades add $75-$100. Same-day emergency service may add $50-$75. Call (281) 906-4783 for exact pricing for your door.
Can I replace just one torsion spring if only one broke?
Technically yes, but it's not recommended. The new spring will have different tension than the worn spring, causing door imbalance, potential track binding, and faster wear on the new spring. You'll also need another service call when the second spring breaks soon. The extra $50-$75 to replace both is money well spent.
How long does double spring replacement take?
Professional double torsion spring replacement takes 45-90 minutes depending on door size, access, and whether additional repairs are needed. This includes releasing old spring tension, removing old springs, installing new springs, winding to proper tension, and balance testing.
Do two-car garages always have two springs?
Most two-car garage doors (16' wide) have two torsion springs, but some lighter doors or older installations may have only one heavy-duty spring. Two springs are preferable as they share the load, last longer, and provide a safety margin if one fails. We can often upgrade single-spring systems during replacement.
What warranty comes with spring replacement?
At Lemus Garage Door Services, all spring replacements include a 5-year warranty covering both parts and labor. If a spring fails within the warranty period, we replace it at no cost. High-cycle springs often last beyond the warranty, giving you worry-free operation for 10+ years.
