Garage Door Balance Adjustment in Strathroy-Caradoc
Released from the opener, the door will not hold anywhere.
In plain words
The whole service is built around one simple test that door manufacturers and safety bodies describe the same way. With the opener released, the door is lifted by hand to roughly a metre off the floor and let go. A balanced door stays where it is. One that drifts upward is carrying too much spring tension; one that sinks is carrying too little. The technician reads that behaviour at several heights, checks the door is level across its width, and then adjusts the counterbalance a quarter turn at a time, testing to the manufacturer's specified height and tolerance, until the door meets that standard and moves smoothly.
How the visit goesThe door has grown heavy so gradually you stopped noticing, until a visitor tried to lift it and could not. The opener still manages, but it sounds strained, the chain slaps on the way up, and the wall button gets pressed twice most mornings.

How the visit goes
Friction along the path
Some doors that feel heavy are not short of spring tension at all; they are dragging. The technician runs a hand and an eye along the vertical and horizontal tracks for dents, misaligned joints and brackets that have pulled away from the jamb, spins each roller to find seized bearings or cracked wheels, and flexes each hinge for play or splits. Dry, worn rollers alone can add real effort to every lift. Binding at one point in the travel, rather than heaviness everywhere, is the signature of a friction problem, and correcting it first means the springs are then adjusted to the door's true weight rather than to the drag.
Fitting the opener to the balanced door
Once the door holds at every height by hand, the opener is reconnected and treated as its own step. Its travel limits are checked so the door closes fully onto the floor and opens to the correct height without straining against the stops. The force settings are reviewed, and where they had been raised to cope with a heavy door they are brought back to a sensible level, because the door no longer needs the help. The photo eyes are cleaned and aligned. The technician then runs several powered cycles and listens for the motor working lightly and evenly through the whole travel.
Lubrication that keeps the adjustment true
A balanced door stays balanced longer when the parts that move on every cycle are kept easy. Twice a year, spray a lubricant made for garage doors along the torsion spring, onto each hinge pin, the roller stems and bearings, and the bottom bracket pins, then run the door a few times. Wipe the tracks clean but leave them dry, since a coated track collects grit and lets rollers slide. Avoid heavy grease. Friction is part of what the hand test measures, so a door that is well lubricated reads true, and the springs are not asked to overcome drag that a moment's maintenance would remove.

What affects the quote
Rollers, hinges and friction repairs
Seized rollers or worn hinges that made the door heavy are pointed out and offered as optional items, since replacing them while the technician is at the door is efficient.
Torsion or extension springs
Winding a torsion spring with bars and moving an extension spring's hook are different procedures with different setup, and the type of counterbalance on your door is the first thing that shapes the quote.
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.
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?
- Does the door sit level when closed, or is one corner higher?
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.
Why does my door sink or slam down when released?
Not enough spring tension for the door's weight. Springs lose a little pull as they age through thousands of cycles, and a door gains weight when insulation, windows or a heavier seal are added. Either way the door outweighs its springs. Adding tension in measured quarter turns restores the hold, provided the springs are sound; if they are near the end of their life, new ones are the right answer.
How often does a garage door need a balance adjustment?
There is no fixed interval; the door tells you. Many doors go years between adjustments, especially when they are lubricated and the springs were sized correctly. A hand test each season is the reliable guide: if the released door holds at about a metre and stays fully open, it is fine. When it starts to drift or sink, that is the time.
