In our years serving Scotland, we've seen this problem again and again: a snapped garage door spring leaves homeowners panicked, thinking they need a complete system overhaul. The truth is simpler and less expensive. A broken spring is fixable, often without replacing the entire door or both springs. Understanding why springs fail and what your options are will save you hundreds of pounds.
Torsion springs and extension springs wear out the same way your car's suspension does: through repeated use and friction. A typical residential spring completes 10,000 to 20,000 cycles (one open and close equals one cycle). Most springs last 7 to 9 years, not 10. When they fail, it's rarely sudden damage. It's fatigue.
Springs snap for three main reasons. First, normal wear. Springs lose tension gradually after thousands of cycles. Second, rust and corrosion, especially in damp Scottish climates where salt air near coastal areas accelerates oxidation. Third, improper maintenance. Lubrication matters. A dry spring breaks faster than a lubricated one.
If your garage door suddenly won't open or feels heavier than usual, a snapped spring is likely the culprit. You'll often hear a loud bang when it happens. Do not force the door open. Do not use the opener. A broken spring means the door's full weight (typically 130 to 180 kilograms) falls on the opener motor, which will burn out within minutes.
A snapped spring costs between £150 and £350 to replace, depending on spring type and labour. Single torsion springs run cheaper than extension springs. If both springs are the same age (usually installed together), replacing just one creates an imbalance. The newer spring works harder, shortening its lifespan. This is why many technicians recommend replacing both springs at once, even if only one has failed. Total cost then rises to £250 to £500.
Compare this to a new garage door (£800 to £3,000+) or an opener replacement (£400 to £800). Spring repair is the budget option, and it works. Before you commit to anything, get an accurate estimate. We've written a detailed guide on how to get an accurate garage door quote without overpaying, which covers what questions to ask and red flags to watch for.

Extension springs run along the sides of the door opening. They stretch and contract to lift the weight. Torsion springs sit above the door, twisting to store and release energy. Torsion springs are generally more durable and safer. Extension springs can snap suddenly, sometimes creating a safety hazard if the cable breaks too.
If your door uses extension springs and one snaps, replacing both is non-negotiable for safety. The imbalance is dangerous. Torsion springs allow single replacement with less risk, though matching age and quality matters for smooth operation. Your technician can advise which approach suits your setup. Our complete spring replacement guide covers both types in detail.
Maintenance prevents early failure. Lubricate springs twice yearly with a silicone-based garage door lubricant. Avoid WD40 or general oil, which attract dust and gum up over time. Check the door balance monthly by disconnecting the opener and manually lifting the door halfway. It should stay put. If it drops or rises, springs are weakening.
Regular inspections catch rust and corrosion before they compromise the metal. In Scotland, where moisture is constant, this matters. A professional garage door maintenance tune-up costs £80 to £150 and typically adds years to spring life.
Never attempt spring replacement yourself. Torsion springs are under extreme tension (up to 180 kilograms of force). A slip or miscalculation causes serious injury. Extension springs can snap unexpectedly and whip dangerously. Professional installation takes 1 to 2 hours and includes safety checks and balance testing.

The garage door won't open, feels much heavier, or you hear a loud bang. The door may hang unevenly or the opener may not function despite no other visible damage.
No. Do not open or close the door manually or with the opener. A broken spring means the full door weight rests on the opener, causing motor burnout and safety hazards.
One spring costs less upfront, but two springs matched in age provide balanced operation and longer lifespan. Replacing one leaves an imbalance, shortening the new spring's life to 5 to 6 years instead of 7 to 9.
Most springs last 7 to 9 years or 10,000 to 20,000 cycles. Proper lubrication and maintenance can extend lifespan by 1 to 2 years.
