Extension Spring Replacement

You pulled the red cord to open the door during a power cut and it barely moved. Lifting it took your whole weight, and when you let go it came down hard.

In plain words

When one extension spring breaks, the other is replaced with it. The two springs were fitted together, have stretched the same number of times and have rusted in the same air, so the survivor is near the end of its life. More importantly, a door balances only when both sides pull equally; a new spring paired with a tired one lifts one corner ahead of the other and twists the door. Fitting a matched pair rated for the door's weight lets the technician set both sides to the same hook position and hand back a door that rises level and holds where it is left.

How the visit goes

  1. Scene 1

    Both springs, side by side

    Even when only one spring has snapped, both are read closely. The technician looks for gaps opening between coils with the door up, which means the wire has stretched and lost its pull; rust pitting and scale, especially where the spring sits nearest the back wall; a spring hanging visibly longer or lower than its partner; and end loops that have opened or cracked. The two are compared for length, coil diameter and wire size, because springs of different ratings are sometimes found on the same door after a past repair. Whatever is found, the outcome is the same, a new matched pair, but the reading tells the technician what rating the door really needs.

  2. Scene 2

    Renewing the hardware around the springs

    Anything the inspection flagged is dealt with while the door is open and the springs are slack, because that is when the work is easiest and the parts are already in hand. A pulley with a grooved wheel or a stiff bearing is swapped for a new one on its fork or bracket. Lift cables with rust at the loop or broken strands are replaced along with the springs. A rear hanger that had loosened is re-fixed with lag screws into a sound joist, and a bent front bracket is straightened or renewed. Bottom brackets eaten by salt and rollers with cracked wheels are changed at the same time.

  3. Scene 3

    Containment cables, and leaving them be

    Your door now has a cable running through the middle of each spring, anchored at the back hanger and at the front of the track. It carries no meaningful load while the springs work, though a trace of slack as the door cycles is normal. Its job begins only if a spring ever breaks, when it holds the pieces on the cable instead of letting them fly. It should not be removed, used to hang anything, or tied back to the wall. If it ever looks badly slack, frayed or pulled from its anchor, call to have it corrected promptly rather than waiting for a routine visit. A home inspector looks for this cable when a house is sold.

What shapes the quoteBroughdale Garage Door Specialists

Working room around the springs
Shelving, a stored canoe or a car parked under the tracks slows the work along the horizontal run. Clearing the sides of the garage beforehand keeps the time on the quote short.
Pulleys that need renewing
Each side has two pulleys, and a wheel worn to a groove or a bearing that has stiffened is replaced with the springs. The quote names how many and which type.
Time of the call
An evening, weekend or holiday visit costs the same amount as a weekday daytime appointment for an extension-spring replacement. The technician confirms the exact figure once the springs, cables and door weight have been checked on site.

Homeowners ask

My springs squeak and twang. Is that normal?

Some noise is ordinary. Extension springs stretch and relax on every trip, and a dry coil or a pulley with a dry axle will squeak, especially in cold weather; a light spray of lubricant along the springs and a drop on each pulley usually quiets it. A sharper twang, or a new grinding from a pulley, is worth a look, since a stiff pulley loads the spring and wears the cable.

How do you know which springs my door needs?

By weight. Extension springs are rated for the weight they lift, so the technician releases the opener and weighs the door on a scale, then matches that figure and the door's height to a spring rating and stretch length. The old springs are measured as a check on wire size, coil diameter and length. Where the two disagree, the scale decides, since doors gain weight from added insulation or panels.

What happens during the visit?

The technician releases the opener, opens the door fully and clamps it so the springs go slack, then inspects springs, pulleys, cables, hangers and containment cables and weighs the door. The old springs come off, a matched pair goes on with containment cables through them, the lift cables are routed over the pulleys and the two sides are set to matching hook positions. The door is balanced by hand, the opener reconnected and its reversing tested with you watching.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 52 in 100 homes · older homes
  • About 52% of homes in London were built in 1980 or earlier, according to the 2021 Census.In a mature neighbourhood the garage door is often the single largest feature of the front elevation, so keeping the original look matters. Modern insulated doors come in raised-panel and carriage styles that echo the older designs while running on today's torsion hardware.
  • Single-detached houses make up about 49% of homes in London (2021 Census).Where housing is mixed, the doors are mixed as well: wide insulated doubles, narrow singles in rows and the occasional rolling door on a small commercial unit at the corner. Spring type, cable length and opener strength are matched to each door individually.
