Garage Door Spring Repair
Tension and balance reset on intact springs so the door stops fighting the opener.

Broken or fatigued springs replaced as a matched pair and re-tensioned to the door.
What's involved
Garage Door Spring Replacement
When a spring has actually broken there is no repair path. The wire has fatigued and separated, usually with a bang loud enough to be mistaken for something hitting the house, and the door is now its full weight with nothing holding it. Replacement means new springs sized to the specific door rather than to what happened to be on the van: correct wire diameter, inside diameter, length and wind direction, fitted as a matched pair and wound to the tension that door needs. Doing that properly is what makes the difference between a door that lasts and a door that comes back.

Symptoms
Signs You Need This Service
- A loud bang from the garage, then a door that will not lift.
- A visible gap of a few centimetres in one spring coil.
- The opener runs, strains and stops without moving the door.
- The door is far too heavy to lift by hand.
- The door drops fast when released instead of staying put.
Repair or replace?
New springs restore the counterbalance to what the door actually needs, and matched pairs then age together rather than one carrying the other. Life expectancy depends on cycles, not calendar years, so a household that uses the garage as its main door should expect a shorter interval than one that uses it for a car twice a day. Higher-cycle springs are available where a door is used heavily and the geometry allows them, and that trade-off gets set out openly. What does not get done is replacing one spring of a pair to save a little now and unbalance the door for the rest of its life.

Root causes
What Actually Goes Wrong
Cycle life reached
Springs are rated for a number of open-and-close cycles, and every cycle works the wire a little. Reaching that rating is the normal, expected end of a spring's service rather than a defect.
Undersized for the door
A spring wound for a lighter door works harder on every cycle and fails early. It happens most often when an uninsulated door was replaced with a heavier insulated one and the original springs were reused.
Corrosion in the coils
Rust pits the wire surface and each pit is a place a crack can start. Unheated garages with damp floors and salt carried in on vehicles are the usual setting for it.
Cold on a tired spring
Low temperatures do not break a sound spring, but they contract the steel and stiffen everything around it, which is why a spring near the end of its life so often gives up on the coldest morning of the year.
Local conditions
Why This Matters in Newmarket
Two Newmarket patterns drive most of the replacement work here. The first is cold: with a January mean around minus 7.4 degrees and a mean daily low near minus 11.1, a spring already at the end of its cycle life very often fails on a January morning rather than in July. The second is retrofit history. Bristol-London and the other 1970s and 80s suburbs are full of wide two-car doors, and where an original uninsulated door was swapped for a heavier insulated one without re-springing, the springs have been overloaded on every cycle since. Both cases end the same way, and both are worth catching at the balance-check stage instead.
Safety
What to Handle Yourself
This is the single most dangerous routine job on a residential garage door. A wound torsion spring stores enough energy to break bones, and the bottom brackets remain under full tension even when the door is open. Do not attempt to remove, install or wind springs, and do not remove a bottom bracket or a winding cone set screw. If a spring has broken with the door up, keep everyone clear and do not pull the release cord. If it broke with the door down, leave it down. Send the details through the form and let the door stay where it is.
The visit
How We Work Through It
-
Identify the door, not the spring
The door is weighed or calculated, the drum size and track radius noted, and the existing spring measured for wire, inside diameter and length. Springs are then specified to the door rather than matched to whatever was there.
-
Release safely and strip out
Remaining tension is let down under control with winding bars before anything is loosened. The failed spring, and its partner, come off with the shaft supported and the door secured.
-
Fit as a matched pair
Both springs are replaced together so the pair shares load and remaining life evenly. Bearings, the centre plate and the anchor backing are checked and replaced where worn while access is open.
-
Wind, balance and test
Springs are wound to the calculated tension, drums set with equal cable wraps, and the door tested by hand for hold and level travel before the opener is reconnected and its force settings reviewed.
Questions
Garage Door Spring Replacement FAQs
Can a broken spring be welded or rejoined?
No. The wire has fatigued along its length, not just at the point where it separated, and heat from welding would destroy what temper remains. Any repair attempt would put a household in front of a component holding enough energy to injure someone. Replacement is the only safe outcome, and it is a routine job when done with the right springs and the right tools. The useful conversation is about sizing and cycle rating, not about salvaging the broken wire.
Why replace both springs when only one broke?
Because they have done the same work. Both springs have been through the same number of cycles in the same conditions, so the intact one is close behind the failed one, and replacing a single spring means a second call-out and a second labour charge shortly afterward. Mismatched springs also share load unevenly, which leaves the door out of balance and pushes the imbalance onto the opener. Replacing the pair is the cheaper decision measured over any sensible period.
How long do garage door springs last?
They are rated in cycles rather than years, so the honest answer depends entirely on use. A door opened and closed twice a day will take many years to reach a rating that a family using the garage as its main entrance six or eight times a day will reach far sooner. Corrosion, mis-sizing and an unbalanced door all shorten it further. We can tell you the wire and length fitted and what its cycle rating implies for your pattern of use, which is more useful than a number of years.
Will new springs fix my opener problems too?
Frequently they improve them, because most so-called opener problems are load problems. When springs weaken, the motor carries weight it was never sized for, so it strains, overheats, trips its force setting or stops part way. Restoring proper counterbalance takes that load off. If the opener has a genuine electrical or mechanical fault, correcting the springs will not hide it, and we will say which of the two we are looking at rather than replacing both and calling it solved.
