Garage Door Balance Adjustment in Wychwood Park
Since the new insulated panels went in, the door feels like a different animal.
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.
How the visit goesSomeone replaced the springs a while back and the door has bounced at the top ever since. It slams open against the stops, then creeps down a few inches, and the opener trolley rattles because the door is pushing where it should be resting.

How the visit goes
Looking at the opener's settings without touching them yet
The opener is inspected as a witness rather than a cure. The technician checks its force and travel settings, listens for strain during a powered cycle, and notes whether it reverses near the floor or stalls part way up. A force setting that has been turned up over the years is a strong hint that someone has been compensating for a door that grew heavy. Those settings are left alone for now, because the right order is to balance the door first and then fit the opener to it. Any change made to the opener before the door is corrected would only mask what the door is asking for.
Resetting the cables so the door sits level
If one corner of the door sat high, that is corrected before the final tension is set. The technician releases the spring tension enough to take the load off the drums, loosens the set screws on the drum on the low side, takes up or lets out cable until the door is level, and locks the drum again with the cable seated snugly in its groove. The bottom of the door is checked against the floor along its whole width, and both drums are confirmed to show the same number of wraps. Only then is the spring tension brought back up, because tension applied to a crooked door simply loads one side more.
Watching for the early signs of drift
You will now know what the door feels like when it is right, which makes small changes easy to spot. A door that begins to close with a heavier thud, an opener that pauses at the top or hums a little longer, a gap appearing under one corner, or a door that no longer quite stays fully open when released are all early signs. Cold weather can make the door feel a little heavier for a few weeks without anything being wrong. But a door that stalls, races or no longer passes its balance check is telling you to stop using it and book an inspection promptly rather than waiting out the season, since the cause is not always minor.

What affects the quote
Extension-spring containment and pulleys
On an extension door, a missing containment cable is added and worn pulleys are replaced with the adjustment. Each is a small parts line on the quote.
Commercial or oversized doors
Doors wider or heavier than a standard residential opening use heavier springs, sometimes several on one shaft, and take longer to wind and test, which the quote reflects.
Door out of level
A door with one corner high needs its cables reset on the drums before the tension is set, which adds a step to the visit and is listed as its own item.
What to have ready
- Is there storage or shelving near the spring shaft that needs moving?
- When you release the door and lift it by hand, does it drift up, sink, or stay put?
- Is it a single or a double door, and roughly how tall?
Garage Door Balance Adjustment: questions
QuestionsThe door was fine until a power cut. Why is it heavy now?
During a power cut the door is often released and moved by hand for the first time in years, and what people discover is a door that had already grown heavy while the opener quietly covered for it. The outage did not change the springs; it revealed them. A balance check confirms what the door weighs against what the springs give, and resets them to match.
Can the opener's force setting be turned up instead of adjusting the springs?
The opener is built to move a balanced door, and its force limit is what makes it stop and reverse on contact. Raising that limit to lift a heavy door pushes the safety behaviour out of its intended range and works the motor and gears hard. The sound order is to balance the door first, then set the opener to suit it. Both are done in the same visit.
How many turns does a torsion spring need?
As a starting point, roughly one full turn for every foot of door height, so a seven-foot door carries a little over seven turns and an eight-foot door a little over eight. The exact figure depends on the drum size and the spring's rating, so the technician winds to the estimate and then fine-tunes by quarter turns until the hand test passes at every height.
