Garage Door Balance Adjustment

With the door closed, daylight shows under one bottom corner and the seal is squashed flat at the other. As it rises, the left side leads by an inch or two, and the top section twists slightly as it turns into the horizontal track.

  1. When a spring breaks, the safe approach for the household is to leave the door where it is, keep people and vehicles clear, and avoid running the opener, which can damage the top section, the trolley or the gear drive.

In plain words

An opener is designed to move a door that is already balanced, and every safety feature in it assumes that. The force it applies is limited so the door will stop and reverse when it meets something, and that limit only makes sense when the door is close to weightless. When springs lose tension, the opener has to lift real weight, its motor and gears work harder, and it may reverse or stall for no obvious reason. A balance adjustment puts the weight back on the springs where it belongs, so the opener can return to the light duty it was built for and its reversing behaviour is dependable again.

Sound familiar?

Since the new insulated panels went in, the door feels like a different animal. It closes with a thud, the opener labours where it used to hum, and lifting it by hand takes a proper heave rather than a fingertip.

How the visit goes

  1. 1

    Inspecting the springs before any turns are added

    Adjustment only makes sense on a spring that is sound, so each one is examined closely. On a torsion system the technician looks for a gap in the coil, rust pitting, uneven coil spacing and a cone that has slipped on the shaft, and measures the wire size, inside diameter and length to confirm the spring suits the door's weight. On extension springs the check is for stretched or opened coils, a broken end loop and the presence of a containment cable. A spring that has simply lost a little tension can be wound up; one that is undersized or near the end of its cycle life is explained and offered as a replacement instead.

  2. 2

    Adding or releasing quarter turns on a torsion spring

    With one winding bar seated firmly in the winding cone and a second ready, the technician loosens the cone's set screws and either adds tension by levering the bar upward or releases it by letting the bar down, always a quarter turn at a time, always with a bar in the cone. After each quarter turn the set screws are tightened onto the shaft, the clamp is removed and the door is lifted by hand to test. A door that sank now holds a little higher; a door that climbed now settles. On a two-spring door the same change is made to both springs so they share the load equally.

  3. 3

    A record of the setting

    Before leaving, the technician tells you how the door was set: the number of turns on each torsion spring or the hook position on each extension spring, the spring dimensions, the door's measured weight if it was weighed, and any parts that were replaced. Writing this on a card by the opener or inside the manual saves a future technician from starting from scratch, and it gives a reference point if the door ever starts to drift. Springs age gradually, so a note that says the door held at a certain number of turns tells a later visit how far things have moved.

What affects the quote

  1. 1

    Lubrication and tune-up

    Some people combine the balance adjustment with a full lubrication and hardware tightening. That bundle is priced as a whole and saves a separate maintenance visit.

  2. 2

    Condition of cables and drums

    Cables that are fraying or drums with worn grooves found during the check are recommended for replacement while the system is being set, and quoted as their own items.

  3. 3

    Door height and lift type

    Taller doors and high-lift or vertical-lift hardware carry more spring turns and different drums, so setting and testing them takes longer than a standard seven-foot door.

Garage Door Balance Adjustment: questions

Advice · (226) 270-3930

Can a door with a broken spring be balanced?

A broken spring is replaced rather than adjusted; there is nothing left to wind. On a two-spring door the technician normally replaces both, since the survivor has the same age and cycle count, and then balances the door on the new pair. Until the visit, leave the door closed and avoid running the opener, which is not designed to lift the door's full weight on its own.

How long do garage door springs last?

Springs are rated in cycles, one cycle being an open and a close. A standard residential spring is commonly rated for around ten thousand cycles, which for a family using the door several times a day works out to roughly seven to ten years. Higher-cycle springs are available. As a spring nears its rating it loses tension, which is often why a balance adjustment is needed.

I added insulation panels to my door. Does that affect balance?

Yes, and it is one of the most common reasons a door starts to sink. Springs are matched to the door's weight, and insulation kits, replacement sections, windows or a heavier seal add weight the original springs were not sized for. A technician can weigh the door and either add tension to suit it or, if the added weight is beyond what the springs can carry, specify new ones.

What the census means at the door

52%

Older homes. About 52% of homes in London were built in 1980 or earlier, according to the 2021 Census.

Older houses frequently have a garage door that was replaced once already, sometimes with a door chosen for the opening rather than the building. When that door reaches its end, there is a chance to pick a style that suits the house properly, and we measure with that in mind.

49%

A mix of homes. Single-detached houses make up about 49% of homes in London (2021 Census).

In a neighbourhood with both detached and attached homes, some customers decide alone and others report to a board or property manager. We adapt the visit accordingly, giving a homeowner options at the door and a manager a written summary they can circulate.
