Garage Door Spring Replacement
Broken or fatigued springs replaced as a matched pair and re-tensioned to the door.

Tension and balance reset on intact springs so the door stops fighting the opener.
What's involved
Garage Door Spring Repair
Not every spring problem is a broken spring. A door that has become heavy to lift by hand, drifts back down when left half open, creeps up off the floor, or lifts unevenly usually has springs that are intact but no longer holding the tension the door needs. That is an adjustment job rather than a parts job: tension reset with winding bars, the cable drums re-wound so both sides match, and the bearings, shaft and end brackets serviced. Balance is the whole point. A correctly balanced door stays roughly where you leave it anywhere in its travel, and an opener attached to one lasts far longer.

Symptoms
Signs You Need This Service
- The door feels much heavier by hand than it used to.
- Left half open, the door drifts down or creeps up instead of staying put.
- One side leads the other as the door lifts.
- The opener strains, slows or stops part way up.
- The door thumps down hard over the last foot of travel.
Repair or replace?
Re-tensioning restores a spring that has relaxed; it cannot restore one that has fatigued to the point of cracking or has lost coil integrity. Springs are rated in cycles rather than years, so a two-car household using the door six times a day gets through its rating far faster than a household using it twice. The honest test on site is whether the spring holds the adjustment: if tension has to be added repeatedly, the wire is tired and replacement is the durable answer. Where a spring was previously mis-sized, adjustment can only ever partly compensate, and that gets said rather than papered over.

Root causes
What Actually Goes Wrong
Tension lost over cycles
Torsion springs relax gradually across thousands of cycles. Nothing breaks, but the counterbalance drops away and the door gets progressively heavier, which the household usually notices only once the opener starts labouring.
Mismatched previous replacement
A spring sized to the wrong wire, length or inside diameter will never balance the door properly. It is a common finding on houses where a spring was replaced once, cheaply, years ago.
Uneven drum winding
If the cables are not seated with equal wraps on both drums, one side lifts ahead of the other. The springs may be perfectly good while the door still travels out of level.
A door that gained weight
Fitting a heavier insulated section, adding a strut, or a section that has absorbed water all change what the springs are being asked to hold. The original tension is then simply wrong for the door.
Local conditions
Why This Matters in Newmarket
Balance loss shows up in clusters here, because Newmarket built in waves. Quaker Hill went up between 1967 and 1977, Woodland Hill is 52 percent 2006 to 2010, Glenway is 54 percent 1981 to 1990 and Copper Hills finished its last big phase in 2017. Doors installed within a few years of each other, in households that use the garage as the main entrance, reach the same cycle count at roughly the same time, which is why one street can generate several heavy-door complaints in one season. The town's density, third among Ontario census subdivisions, means those streets are close together. If a neighbour's spring has just gone, a balance check on yours is a reasonable move.
Safety
What to Handle Yourself
A torsion spring holds enough stored energy to cause serious injury, and adjusting one needs correctly sized winding bars and a controlled sequence. Screwdrivers, rebar, drill bits and pliers are how people get hurt. Do not attempt to wind or unwind a spring, do not stand under a spring you are working near, and do not loosen a set screw on a winding cone to see what happens. Testing balance by hand with the opener disconnected is safe and useful. Everything past that point belongs to someone with the bars and the practice to use them.
The visit
How We Work Through It
-
Measure the imbalance
With the opener disconnected, the door is lifted by hand and tested at several heights to see where it holds, where it drifts and whether one side leads. That tells us whether this is a tension job or a parts job.
-
Inspect the assembly
Springs are checked for coil gaps, corrosion and previous mis-sizing; the shaft, centre bearing, end bearing plates and anchor backing are checked for wear and for whether they are fixed into sound structure.
-
Reset tension and drums
Tension is adjusted with proper winding bars, never improvised tools, and the cable drums are re-wound so both sides carry equal wraps. Small increments, tested between each one, rather than one large guess.
-
Retest, then reconnect
The door is retested by hand for hold and level travel, and only then is the opener reconnected and its force and limit settings reviewed against the door's new, lighter behaviour.
Questions
Garage Door Spring Repair FAQs
How do I tell whether my spring needs adjusting or replacing?
Disconnect the opener with the release cord while the door is closed, then lift the door by hand to about waist height and let go. If it holds roughly where you left it, the springs are intact and the system is close to balanced. If it slides down or shoots up, it needs tension work. If you can see a clear gap in a coil, or the door is suddenly far too heavy to lift at all, the spring has broken and adjustment is not an option.
Why does re-tensioning help the opener?
Because a properly balanced door weighs almost nothing at the operator. The springs are meant to carry the door and the opener is meant only to guide it and hold it in place. When tension drops, the motor takes up the difference, which loads the drive gear, the rail and the door arm bracket far beyond their design intent. Restoring balance often removes symptoms people attribute to a failing opener, and it stops the next opener from failing early too.
The door is fine but noisy. Is that a spring issue?
It can be, though noise more often comes from rollers, dry hinges or loose track brackets. Springs make a distinct sound: a rhythmic squeak or a metallic groan as the coils rub, usually improved by proper lubrication of the coils rather than the surfaces around them. A grinding noise from the bearings at either end of the shaft is different and points to the bearing plates. We check which of those is actually producing the sound instead of lubricating everything and hoping.
Can both springs be adjusted if only one seems weak?
On a two-spring door they are always considered together, because balance is the sum of both. If one has relaxed more than the other, adjusting only that side may level the door temporarily while leaving the pair mismatched in remaining life. We measure the door’s behaviour first, adjust both to bring the assembly into balance, and flag it plainly if the difference between the two suggests one is near the end of its cycle life.
