- The call
- You heard a sharp bang from the garage, and now the opener hums for a second and gives up. The door lifts a few centimetres at most, then settles back down as if something very heavy is holding it in place.

After pulling the red release cord, you tried lifting the door yourself and it would barely leave the floor. A door that used to glide up with one hand now takes real effort, which points to the counterbalance rather than the opener.
A spring that breaks with the car inside puts the whole morning on hold, and this service is designed to get that door working again in a single visit. The technician arrives with a range of spring sizes, secures the door so it cannot move, identifies exactly which spring the door needs, and installs and winds the replacement. Once the door balances by hand, the opener is reconnected and tested. Until then the safe approach is simple: leave the door where it is, keep clear of it, and share a photo of the spring area so the right parts arrive on the truck.

Scene 1
Before anything is measured or removed, the door and the opener are put into a controlled state. The opener is unplugged and the trolley released so the motor cannot move the door partway through the job. The door is brought fully closed, and locking pliers or clamps are set on the track just above a roller so the door stays down while spring tension changes. The technician clears the space beneath the shaft, checks that people and pets are out of the garage, and looks at where a vehicle sits so the ladder and winding position are safe.
Scene 2
Winding is where a spring takes on its working tension, and it is done with two solid steel bars sized to the holes in the winding cone. The technician stands to the side of the cone, inserts one bar, turns a quarter turn, inserts the second bar, and transfers the load from bar to bar so the spring is never held by less than a full bar. The number of quarter turns is counted against the door height and drum type. When the count is reached, the spring is stretched slightly toward the drum and the set screws are tightened to the shaft while the last bar still carries the load.
Scene 3
The technician leaves you with the specification of what was installed: wire size, inside diameter, length, wind direction and the cycle rating chosen, along with notes on any bearings or cables replaced. Keep that record with the door's paperwork or photograph it. It means future service starts from known numbers rather than fresh measurement, and if a door section or opener is ever changed, the installer can confirm the springs still suit the door's weight. Many technicians also mark the installation date on the spring or centre bracket so the age of the system is easy to read later.
What shapes the quoteThorold Garage Door Repair Co.
FeesSame any hour
Not necessarily, and that is fine. The paint colour on the winding cone or coil is a code that identifies wire size and wind direction, and different suppliers use their own schemes, so a matched replacement can carry a different colour than the spring it replaces. What matters is that the wire size, diameter, length and wind direction suit the door's weight and height, which is confirmed by the balance test.
Once or twice a year is a good rhythm, with autumn the most useful time because cold thickens grease. Use a garage-door lubricant, typically a silicone or lithium spray, applied along the coils so it works between them as the door cycles. Hinges, roller bearings and the end bearings benefit from the same treatment. Keep the track itself dry, since lubricant there gathers grit and slows the rollers.
Most residential replacements are completed in one visit. Securing the door, measuring, removing the old spring, fitting and winding the new one, balancing and testing the opener typically takes an hour or two, longer if bearings, cables or a bent top section are also being dealt with. The technician confirms the scope after the first checks, so you know what the visit involves before the work starts.
