How to Replace a Garage Door Spring in the UK
How Do I Safely Replace a Garage Door Spring?
Replacing garage door springs involves securing the door, unwinding remaining tension, removing the broken unit, and installing a new spring safely.
Replacing a garage door spring is a high-risk task because these components store significant mechanical energy. Before beginning, ensure the garage door is in the fully closed position to prevent the door from dropping unexpectedly during the process. Secure the door with locking pliers or a C-clamp on the guide tracks to avoid accidental movement while working.
You must identify whether your door uses side-mounted tension springs or a horizontal torsion spring system. Side-mounted springs are typical on “up-and-over” doors, whereas torsion springs are commonly found on sectional garage doors. Never attempt to remove a torsion spring without the correct winding bars, as these can cause severe injury if they slip under tension.
⚡ In a Rush? Key Takeaways
- Standard spring replacement costs typically range between £50 and £100 per unit.
- Up-and-over door spring failure is common after 10,000 to 15,000 operating cycles.
- Torsion springs store enough force to cause fatal injury if released incorrectly.
- Consult a specialist if the door mechanism shows signs of structural wear.
Can I Replace the Spring on My Garage Door Myself?
You can replace side-mounted springs yourself with basic tools, but professional assistance is mandatory for torsion spring systems.
DIY replacement is generally limited to side-mounted tension springs found on older up-and-over door designs. If you possess mechanical experience and the correct tools, such as heavy-duty wrenches and a ladder, you may safely replace these units. Always document the mounting points of the old springs to ensure the new ones are installed at the exact same tension settings.
What Tools Do I Need for the Job?
Essential tools include heavy-duty locking pliers, a socket set, a sturdy ladder, and two professional-grade steel winding bars.
Having the correct equipment prevents the spring from slipping during removal. Using makeshift tools like screwdrivers for winding is dangerous and should be avoided entirely. Ensure you have the following ready before starting:
- Pair of locking pliers for track security
- Adjustable spanner set (13mm to 19mm)
- High-quality steel winding bars for torsion systems
- Safety goggles and thick work gloves
- Lightweight lithium-based grease for the tracks
How Do I Determine the Cost of Garage Door Spring Replacement?
Garage door spring replacement costs vary from £50 to £100 for parts, plus professional labour fees if you hire a garage specialist.
The price of your replacement depends heavily on the spring type and the manufacturer of your door. Identifying the specific part number or spring length is crucial before purchase. You can find more information on identifying your spring specifications to avoid purchasing the incorrect size.
How Much Does a Professional Replacement Cost?
Professional replacement services usually charge between £100 and £200, covering both the premium parts and the technician’s time.
Hiring a professional is often recommended for safety and peace of mind. A trained technician can also inspect your cables and pulleys for wear, which often fail alongside springs. Regular maintenance, such as checking your hardware, can be managed using standard inspection procedures to prolong the life of your entire door system.
Are There Different Costs for Different Door Types?
Yes, torsion springs are generally more expensive than tension springs due to their complexity and specialized installation needs.
Sectional doors require specific torsion spring ratings calculated by door weight. These parts are rarely universal, meaning you must buy the exact spring calibrated for your door’s mass. Up-and-over doors typically use simpler, cheaper tension units.
| Spring Type | Estimated Part Cost | Installation Difficulty |
|---|---|---|
| Side Tension | £50 – £80 | Moderate |
| Torsion | £80 – £120 | High |
Frequently Asked Questions Regarding Spring Repairs
-
Can you manually lift a garage door if the spring is broken?
You can manually lift most doors, but expect significant resistance as the spring is no longer assisting with the door weight.
-
How to adjust garage door springs in the UK?
Adjusting tension requires moving the spring to a different hole on the hanger bracket or using the tensioning bolts on the side.
-
What is the typical lifespan of a garage door spring?
Most quality garage door springs are rated for 10,000 to 15,000 cycles, representing 7 to 10 years of typical daily usage.

Attempting to lift a heavy door with a broken spring poses a risk of back injury. If you must open the door, use a second person to help distribute the load and ensure you have a firm grip. If the door feels excessively heavy, do not force it, as you could damage the lifting cables.
Only adjust tension in small increments to prevent the door from becoming unbalanced. If the door opens too quickly, the tension is likely too high. Conversely, if it drops rapidly, it needs more tension. Before modifying your setup, refer to our guide on calculating required assist force to ensure your adjustments align with safe operational parameters.
If you notice the door struggling to open, it is likely the spring has reached its cycle limit or suffered fatigue. Inspect the coils for visible gaps or breaks periodically. If the coils appear uneven or stretched, plan a replacement immediately to avoid a total system failure.
