⚠️ Garage Door Spring Replacement is One of the Most Dangerous Home Repair Tasks — Never DIY
Every year in South Africa, homeowners are seriously injured attempting to replace garage door springs themselves. Torsion springs are under extreme torque — a single spring on a standard sectional door stores enough energy to break bones, shatter glass, and cause fatal head injuries if it unwinds uncontrollably. This is not a cautious warning — it is a factual statement about stored mechanical energy. Professional replacement requires specialist winding bars, torque wrenches, and training. No YouTube video or blog post makes this safe to do without the correct tools.
Stored torque is lethal
A torsion spring stores 300–500 kg/cm of torque. Releasing this uncontrolled causes violent, uncontrollable rotation of the shaft — capable of breaking arms, crushing hands and causing fatal head injuries
Extension springs become projectiles
A snapping extension spring under tension can travel 10+ metres at high speed. Without safety cables fitted correctly, an extension spring can pass through drywall, shatter car windscreens and cause fatal injuries.
Specialist tools are required
Torsion spring winding requires specific winding bars matched to the spring cone diameter. Improvised tools — screwdrivers, bars — slip under tension and cause instant, violent releases.
Incorrect sizing causes immediate failure
Springs must be matched exactly to door weight, height and drum size. An incorrectly sized spring will fail immediately or cause dangerous door imbalance that can injure anyone nearby.

Garage Door Spring Replacement in Johannesburg — What You Need to Know
The garage door spring is one of the most critical and most under-appreciated components of your garage door system. It carries 80–90% of the door's weight every time it opens and closes — without it, your motor is essentially trying to lift 80–200kg of steel or fibreglass unassisted. When a spring fails in Johannesburg, it does so suddenly, loudly, and completely.
Paskwa Gate Repairs has been replacing garage door springs across Johannesburg and Gauteng since 2008. In that time we have developed a very specific understanding of how springs fail in Gauteng's environment — the effect of Joburg's summer heat on spring metal fatigue, the accelerated wear caused by high-usage estate and complex garages, and the load shedding-related surge in manual operations that shortens spring life significantly.
This page covers everything you need to know about garage door spring replacement in Johannesburg — the two spring types and which doors use them, how to identify a broken spring, why both springs must always be replaced together, how to choose the right cycle rating for your usage level, and what it costs in 2026.
Stop using the door immediately:
If you have heard a loud bang from your garage and the door feels extremely heavy or won't open properly, stop pressing the remote. Operating the motor against a broken spring will destroy it — motors are not designed to lift the full door weight and will burn out within minutes. Call 061 402 6299 before attempting any further operation.
How a Garage Door Spring Works
A garage door spring works by storing mechanical energy when the door closes and releasing that energy to assist the motor (or manual operation) when the door opens. When you close the door, the spring winds up (torsion) or stretches (extension), storing potential energy. When the door opens, that energy is released — effectively reducing the door's apparent weight from 80–200kg to 5–20kg, which is what the motor is actually rated to lift.
This energy storage and release happens on every single open/close cycle. Over 10,000 cycles (the typical service life of a standard spring), the metal experiences metal fatigue — microscopic cracks accumulate until the spring eventually snaps. There is rarely warning. The failure is usually sudden — a sharp crack or bang, often in the early morning when the metal is coolest and most brittle.
Johannesburg-specific factor:
Joburg's significant temperature variation between winter nights (2–8°C) and summer days (28–35°C) causes metal to contract and expand with each cycle. This thermal cycling adds to metal fatigue and can cause springs rated for 10,000 cycles to fail at 7,000–8,000 cycles in Gauteng's climate. Annual lubrication during a professional service significantly reduces this thermal fatigue effect.
Spring Type Guide
Torsion Springs vs Extension Springs — Which Does Your Door Have?
The two types of garage door springs work differently, fit different door types, have different failure modes and different replacement costs. Identifying yours takes 10 seconds.
Torsion Springs
Torsion springs are mounted horizontally on a metal shaft directly above the garage door opening — you'll see one or two large coil springs running across the top of the door. They work by twisting (torquing) as the door closes, storing energy in the coil, then releasing that torque to assist the door opening. Torsion springs are the most common type in Johannesburg homes — used on virtually all sectional and roll-up garage doors.
When a torsion spring breaks, you'll hear a very loud bang and the spring will have a visible gap in the coil — it splits apart at the point of failure. The door will feel extremely heavy. Torsion springs are safer to replace than extension springs because they are contained on the shaft when they break — they do not become projectiles.
Extension Springs
Extension springs run along the horizontal tracks on either side of the garage door opening. They work by stretching (extending) as the door closes, storing energy in elongation, then contracting to pull the door open. Extension springs are used on tilt-up (one-piece) garage doors and some older sectional door designs. They are the older technology and less common in new Johannesburg installations, but still found in thousands of homes — particularly those built pre-2005.
Extension springs are significantly more dangerous when they break — a snapping extension spring under tension can travel 10+ metres at high velocity. South African building regulations require extension springs to be fitted with safety cables that contain the spring when it breaks.
Diagnosis Guide
6 Signs Your Garage Door Spring is Broken or Failing
Some spring failures are obvious — a loud bang, a visible gap. Others are gradual warning signs that give you time to act before a full failure. Know what to look for.
Loud Bang — Spring Has Broken
A sudden, extremely loud bang — often mistaken for a gunshot or something falling — is the classic sign of a torsion spring snapping under full tension. It typically happens overnight or in cold early mornings when the metal is most brittle. The door will feel very heavy immediately after. Stop all operation and call us.
Visible Gap in the Spring Coil
Look at the spring above your garage door (for sectional doors). A broken torsion spring will have a clear 2–5cm gap where the coil has split. The two halves remain on the shaft but the spring is completely non-functional. For extension springs, look along the side tracks — a broken extension spring will hang visibly slack and may have fallen from its mount.
Door Extremely Heavy or Won't Open
Without the spring, the motor is lifting the full weight of the door — 80–200kg — which it is not rated to do. The motor will either refuse to move the door or will move it very slowly. Do not keep pressing the remote. Every attempt burns the motor further. One broken spring can turn a R800 spring repair into a R3,500 motor replacement.
Door Opens 10–15cm Then Stops
Many modern garage door motors have a built-in force limiter — when the motor senses the door is too heavy (because the spring is broken), it stops after a few centimetres rather than burning itself out. This is the motor protecting itself. If your door opens slightly then reverses or stops, a broken spring is the most likely cause.
Door Slow, Struggling or Unbalanced
A spring losing tension (but not yet broken) causes the door to feel heavier than usual — the motor works harder, the door moves slower, and in some cases the door doesn't sit fully square in its frame when closed. These are signs the spring is near the end of its service life and should be replaced before it snaps completely.
Spring is Over 7 Years Old
Springs don't give much warning before failure. If your garage door is over 7 years old and the spring has never been replaced, it is statistically in its final 20–30% of service life. A proactive replacement costs R800–R1,100 and prevents the emergency scenario. During an annual service we assess spring condition and give you a clear timeline.
Critical Advice
Why You Must Always Replace Both Garage Door Springs — Not Just the Broken One
The Matched Wear Principle
Your two garage door springs were installed at the same time and have been through exactly the same number of cycles — every time the door has opened and closed, both springs have wound and unwound together. If one spring has reached the end of its service life and broken, the second spring has reached the same point on the same day.
The unbroken spring is not "fine." It is under the same metal fatigue, has the same microscopic cracking in the coil wire, and will fail within weeks to months of its partner. The only question is whether it fails while you're standing next to it.
The Balance Problem
A new spring and an old spring have different tension characteristics. A door with one new and one old spring will be unbalanced — one side carries more load than the other, causing the door to tilt slightly on its tracks. This uneven loading damages the rollers, cables, tracks and motor over time — creating additional repair costs that far exceed the price of the second spring.
What Happens When Only One Spring is Replaced
Day 1: One spring breaks
You call a technician. They replace only the broken spring. The old spring is still in place, having completed the same number of cycles.
Weeks 1–8: Imbalanced door
New spring vs old spring creates uneven tension. Door tilts slightly. Extra stress on rollers, cables and motor. Increased wear on all components.
Weeks 4–16: Second spring breaks
The unbroken spring — already at end of life — snaps. Another loud bang. Another emergency call-out. Another R800–R1,100 + call-out cost.
Additional damage found
Because the door ran unbalanced, rollers and cables may show wear requiring additional repairs R300–R750.
Had both been replaced initially
R800–R1,500 total. One visit. Balanced door. Both springs on same service life. No additional damage. Next replacement in 7–10 years.
Door Type Guide
Spring Replacement by Garage Door Type in Johannesburg
Different garage door types use different springs, have different replacement requirements, and different price points. Find yours below.
Sectional Garage Door
Sectional doors use torsion springs mounted horizontally on a shaft above the door opening. Most Johannesburg homes built post-2000 have sectional doors with one torsion spring (single doors) or two torsion springs (double doors and heavier doors). The spring works in conjunction with the door's cables and drums to lift the door evenly.
When replacing sectional door torsion springs, we also inspect and lubricate all hinges, rollers and cables as part of a free door service — ensuring the new spring operates in an optimally maintained environment.
Roll-Up / Roller Door
Roller doors use a torsion spring inside the drum or barrel that the curtain rolls around. The spring pre-loads the drum to counterbalance the curtain weight, making it easy to raise manually and reducing motor load. Roller door springs are typically smaller in diameter but wound more tightly than sectional door springs.
Roller door spring replacement is more complex than sectional door replacement because the spring must be correctly wound inside the drum — requiring specific drum tools. An incorrectly wound roller door spring causes uneven rolling and track damage.
Tilt-Up (One-Piece) Door
Tilt-up doors use extension springs that run alongside the door frame or along the ceiling tracks. As the door tilts up, the springs extend and store energy. When the door closes, the springs pull it down. Tilt-up doors are common in older Johannesburg homes — particularly those built in the 1980s–1990s.
Safety cables are mandatory with tilt-up door extension springs. Many older Johannesburg installations do not have them. We fit safety cables as standard with every extension spring replacement — at no extra charge. This is not optional — it is a safety requirement.
Our Process
What Happens During a Professional Spring Replacement
Every spring replacement we do follows this exact process — transparent, safe, and thorough. No shortcuts, no hidden steps.
Safety Assessment Before Touching Anything
We will never start a spring replacement if the door has other structural damage that makes the replacement unsafe. Customer safety comes before completing a job quickly.
Release Existing Spring Tension Safely
This is the step that makes DIY spring replacement genuinely life-threatening. There is no way to safely release torsion spring tension without correct winding bars and training.
Measure and Size the Replacement Springs
We carry a wide range of spring sizes in our vehicles. For standard Johannesburg sectional doors (8m², 10m², 12m², 15m²), we have the correct spring on-board in most cases — enabling same-day replacement without ordering parts.
Install Both Springs and Wind to Correct Tension
Balance Test and Free Full Door Service
The free door service is included with every spring replacement at no extra cost. A spring replacement without a full service is incomplete — the new spring needs to work with properly maintained components to deliver its full cycle rating.

Extend Your Spring Life
How to Make Your Garage Door Springs Last Longer in Johannesburg
You cannot prevent spring failure forever — but you can significantly extend their service life with these maintenance practices.
Lubricate Springs Every 6 Months
Apply a light coat of garage door lubricant (not WD-40, which displaces grease rather than lubricating) to the full length of each spring coil every 6 months. This reduces metal-to-metal friction between coils, significantly reducing fatigue cracking. In Johannesburg's climate, lubrication also prevents surface rust from accelerating fatigue. A R60 spray can extends spring life by 20–30%.
Annual Balance Test
Once a year, disconnect the motor (use the manual release cord) and manually lift the door to mid-height. Release it. A balanced door stays put. If it rises or falls, the springs have lost tension and need adjustment before they snap. This 2-minute test can predict a spring failure months before it happens — allowing planned replacement rather than emergency replacement.
Annual Professional Service
Don't Ignore Changed Door Behaviour
If your door starts moving slower, sounds different (grinding, creaking on opening), or no longer stays balanced at mid-height, these are warning signs. A spring losing tension behaves like this before it snaps. The repair cost of a planned replacement is identical to an emergency replacement — but without the inconvenience of being stuck at home. Book a service when you notice changes.
Customer Reviews
What Johannesburg Customers Say About Paskwa's Spring Replacements
The loud bang at 5:30am on a Saturday morning was terrifying — I thought something had fallen on the roof. Called Paskwa and the technician was at my Rivonia home by 8am. Both torsion springs replaced, door serviced and back to perfect operation by 9am. He also showed me the visible wear on the cables and recommended replacement within 6 months. That's the kind of honest advice that earns a loyal customer.
I had called another company first who quoted me for one spring. Paskwa came for a second opinion, explained why both springs must be replaced, showed me the wear on the second spring, and did both for R1,100 total. A week later the first company called to say they had a slot. I explained Paskwa had already done both springs — the other company admitted they should have replaced both too. Lesson learned.
My garage door spring broke at Fourways Gardens estate. Paskwa told me upfront they'd need to replace both springs and explained exactly why. They also recommended upgrading to the 25,000 cycle springs given how often I use the garage — I have 3 kids and the door opens probably 8 times a day. The upgrade was R350 extra. Given what I was told about the standard spring life at that usage rate, it was an obvious choice.
FAQs
Garage Door Spring Replacement Johannesburg — FAQs
How much does garage door spring replacement cost in Johannesburg?
Torsion spring replacement for a single sectional door costs R800–R1,100 for standard springs or R950–R1,350 for heavy-duty 25,000-cycle springs. Double door replacement costs R1,100–R1,500 standard or R1,350–R1,800 heavy-duty. Extension spring replacement (pair + safety cables) costs R600–R900. All prices include a free full door service and 6-month guarantee. We always replace both springs — never just one. Call 061 402 6299 for a free quote.
Can I replace a garage door spring myself?
No — this is one of the most dangerous DIY home repairs possible. Torsion springs store hundreds of kilograms of torque. Releasing this uncontrolled causes violent, uncontrollable shaft rotation that can break arms, crush hands and cause fatal head injuries. Extension springs can become high-speed projectiles capable of passing through walls. Professional replacement requires specialist winding bars, training and safety equipment that is not available to the public. Never attempt DIY spring replacement. The professional cost (R800–R1,500) is not worth risking your life or permanently injuring yourself. Call 061 402 6299.
How do I know if my garage door spring is broken?
The most obvious sign is a very loud bang from the garage — springs snap suddenly and loudly, often in cold early mornings. After a break, the door will feel extremely heavy (50–200kg) and may only move a few centimetres before the motor stops. For torsion springs (above the door), a visible gap in the coil confirms the break. For extension springs (along the side tracks), the broken spring will hang visibly slack. If you're unsure, call 061 402 6299 and describe what you see — we can usually confirm over the phone.
Why must I replace both springs if only one has broken?
Both springs have completed exactly the same number of cycles — if one has failed, the other is at the same wear stage and will fail within weeks to months. Replacing only one spring: (1) leaves you with a second emergency call-out very soon; (2) creates an unbalanced door that strains the motor, cables, rollers and tracks; (3) costs more overall than replacing both in one visit. We always replace both springs and will explain this honestly before starting work. It is always the right recommendation for your long-term benefit.
What happens if I keep using my garage door with a broken spring?
Stop using the door immediately. Without the spring, your motor is lifting 80–90% more weight than it is designed to handle. Motor burn-out typically occurs within minutes of operation against a broken spring — turning a R800–R1,100 spring repair into a R3,000–R4,500 motor replacement. Additionally, the cable that runs around the drum is now under extreme unbalanced load and can snap, causing the door to drop suddenly. Do not press the remote again — call 061 402 6299 for same-day replacement.
How long do garage door springs last in Johannesburg?
Standard springs are rated for 10,000 cycles. For a typical household opening the garage twice daily, that is approximately 14 years. For a family or estate home using the garage 4 times daily, that is 7 years. For high-usage homes opening 6+ times daily (common in estate complexes), springs may fail in 4–5 years. Johannesburg's temperature cycling between cold winters and hot summers accelerates metal fatigue slightly — lubrication every 6 months can extend spring life by 20–30%. We recommend upgrading to 25,000-cycle heavy-duty springs for any household opening the garage more than 3 times daily.
How long do garage door springs last?
Springs are rated for 10,000–15,000 cycles — about 7–10 years for a typical Sandton home opening twice daily. High-usage estate homes (4–6 times daily) may see 4–6 years. They fail suddenly with a loud bang. Never operate a door with a broken spring.
What is the difference between a torsion and extension garage door spring?
Torsion springs are mounted horizontally on a shaft above the door opening. They work by twisting to store energy. Used on sectional and roll-up doors — the most common type in Johannesburg. They are safer when they break because they stay on the shaft. Extension springs run along the side tracks and stretch to store energy. Used on tilt-up (one-piece) doors and some older sectional doors. They are cheaper to replace but significantly more dangerous when they fail — they can become projectiles. We fit safety cables with all extension spring replacements as a legal requirement and safety necessity.
