Garage Door Spring Repair in Richmond Hill: Signs, Safety and What It Involves

If your garage door suddenly won't open, makes a loud bang, or feels impossibly heavy, a broken spring is the most likely cause. It is the single most common garage door failure we see across Richmond Hill and the wider GTA, and it is also the one repair you should never attempt yourself.

How to tell a garage door spring has broken

Springs do the actual lifting. The opener only guides the door — it is not strong enough to raise a door on its own. So when a spring goes, the symptoms are usually obvious:

• A loud bang from the garage, often heard from inside the house. This is the spring snapping under tension.

• The door will not open with the remote, or the opener strains, hums and stops partway.

• There is a visible gap in the coil of the spring above the door, as though it has been cut.

• The door feels extremely heavy if you try to lift it by hand.

• The door opens crookedly, with one side lagging behind the other.

• Frayed or slack cables hanging beside the tracks.

Why a broken spring is not a DIY repair

A torsion spring on a standard double garage door holds several hundred pounds of stored energy. When it is released without the correct winding bars and technique, it releases all at once. Serious hand and head injuries from spring replacement are well documented, and the tools sold in hardware stores are not the ones the job requires.

There is a second reason to leave it alone: springs are matched to the weight of your specific door. Fitting a spring with the wrong wire size, length or wind direction leaves a door that is unbalanced. That door will run, but it will destroy your opener, wear the cables and rollers unevenly, and fail again far sooner.

Torsion springs and extension springs are not the same

Torsion springs sit on a metal shaft above the door opening and turn as the door moves. They are the more common setup on modern doors, last longer, and fail more predictably. Extension springs run along the horizontal tracks on either side and stretch as the door closes. Older installations often use them, and they should always have safety cables running through them to contain the spring if it breaks.

If your door has two springs and one breaks, both get replaced. The second one has done the same number of cycles and is close behind. Replacing only the broken one means paying for the same call-out twice.

What a proper spring replacement involves

A correct repair is not just swapping the part. It includes measuring the door to confirm the right spring specification, releasing the old spring safely, fitting the replacement, winding it to the correct tension, and then balancing the door. A balanced door will hold its position when stopped halfway with the opener disengaged. If it slides down or springs up, the tension is wrong.

Cables, rollers and the shaft bearings are checked at the same time, because a spring failure often takes them with it. Most single-door spring replacements are completed in about an hour.

How long do garage door springs last?

Springs are rated in cycles, not years — one cycle being one full open and close. A standard spring is often rated around 10,000 cycles. A household that opens the door four times a day will reach that in roughly seven years. A busy family using the garage as the main entrance can get there in three or four. Cold GTA winters and poor lubrication both shorten that life.

Annual maintenance genuinely extends it. Lubricating the springs, rollers and hinges, and correcting the balance before it strains the system, is far cheaper than an emergency call-out on a January morning.
