  1. When a spring breaks, the safe approach for the household is to leave the door where it is, keep people and vehicles clear, and avoid running the opener, which can damage the top section, the trolley or the gear drive.

  2. Pull the manual release only when the door is fully closed unless a technician asks otherwise; a door disconnected while partly open can move on its own if the springs are out of balance.

  3. Never drive a vehicle at a closed door to get out; the door collapses and the stored tension in the counterbalance is released. Use the release, the outside key release, or a technician.

In plain words

What you have afterwards is a door that behaves like a much lighter object. Both corners leave the floor together, the door holds still when you stop it at waist height, and it settles onto the floor instead of slamming. The opener runs quietly, because it is guiding a balanced door rather than hauling a heavy one, and its safety reversing works as designed. Both springs are new, both carry a containment cable, the pulleys turn freely and both S-hooks sit in the same hole. You also get the spring rating and door weight written down, so the next set can be ordered without measuring everything again.

How the visit goes

  1. 1

    The rest of the door, and why the spring went

    A spring rarely fails on its own, so the first look ends with the door it was lifting. The technician checks the rollers for cracked wheels and bent stems, the hinges for splits, the track for a bend or a bracket pulled off the jamb, and the bottom section for a dent that catches. The opener's force setting is noted, since an opener turned up to compensate for tired springs will overpower the new ones. And the history matters: a door recently fitted with insulation panels or windows weighs more than the springs were chosen for, and a door that has been closed onto snow or a bin has had its cables jolted.

  2. 2

    Fitting a pair that matches the door

    The new springs are selected from the door's measured weight and its height, which together give the rating and the stretched length required, and they are fitted as a pair even if one old spring looked sound. The technician checks each new spring's wire size, coil diameter and relaxed length against the specification before it goes up, and confirms the end loops suit the hanger and the pulley fork. The rear loop is hung on the hanger and the front loop takes the pulley fork. On heavier doors that carry two springs per side, all four are renewed together. Nothing is hooked to the door yet; the springs simply hang in place, slack, waiting for the cables.

  3. 3

    A monthly look along the springs

    Extension springs are easy to inspect because they hang in plain view. Once a month, with the door fully closed so the springs are stretched, stand inside and look along each one from the back hanger to the pulley. The coils should be evenly spaced along the whole length; a section stretched wider than the rest is a spring losing its temper. Then raise the door and look again: with the door open the coils should close up tight, and both springs should hang at the same height. Rust bloom, a pulley that sits crooked, a cable off its groove or a containment cable hanging loose are all worth a call while they are still small.

What affects the quote

  1. 1

    One spring per side or two

    Heavier doors sometimes carry a pair of springs on each side rather than one. Four springs, four containment cables and the extra setting time show as their own lines.

  2. 2

    Working room around the springs

    Shelving, a stored canoe or a car parked under the tracks slows the work along the horizontal run. Clearing the sides of the garage beforehand keeps the time on the quote short.

  3. 3

    Track or section damage found on the way

    A bent horizontal track, a bracket pulled off the jamb or a top section twisted by running the opener on a broken spring is separate repair work, quoted on its own.

Extension Spring Replacement: questions

Advice · (289) 805-2215

Should I try to open the door by hand before the technician arrives?

No need, and it is easier on the door if you leave it. With a spring broken or slack, the door is unbalanced and heavy, and lifting it can let it drop or twist a section in the track. If the door is stuck partway, leave it there and keep people and the car away from the opening. The technician brings clamps and props, and the door is secured before it is moved at all.

The door creeps open on its own. Is that a spring problem?

Usually, yes. A door that rises from the floor or from halfway without help has springs pulling harder than the door weighs, which happens when a heavier-rated pair was fitted, when the hooks were set with too much stretch, or when a door has been made lighter by a panel change. It also puts strain on the opener, which has to hold the door down. Weighing the door and fitting the correct rating, set evenly, settles it.

What does the paint colour on the end of the spring mean?

Manufacturers dab a colour on the end coil to indicate the spring's weight rating, which is a handy starting point. It is not the final word: a faded or repainted end coil tells you little, and the pair on an older door may have been a near match rather than the right one. The technician treats the colour as a hint and confirms the rating from the door's measured weight and the spring's own dimensions.

What the census means at the door

38%

Homes of every age. About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.

In a mixed neighbourhood, some garages are detached with plenty of side room and others are tucked under a bedroom with little headroom, so opener and spring choices vary from house to house. Measuring at the door, rather than assuming, is how the right hardware is chosen.

37%

Single-detached houses make up about 37% of homes in Mississauga (2021 Census).

Condo and townhouse garages are frequently used for storage as much as parking, with the door opened many times a day, and the shared walls mean vibration travels. A well-balanced door, tight hardware and a quiet opener are the upgrades residents notice most.
