Extension Spring Replacement
The opener groans on the way up and the door slams the last foot on the way down, hard enough to rattle the windows. The motor is the same one it always was; something in the springs has stopped doing its share.

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.
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.
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
Every extension spring should carry a containment cable, and replacement is the moment to make sure yours do. A containment cable runs through the centre of the spring and is anchored at both ends, to the rear hanger and to the bracket at the front of the track. It does no lifting; its purpose is to hold a spring that breaks so the pieces stay on the cable. Many older doors predate this practice, which a home inspection checklist checks for. When springs are replaced, new containment cables are fitted with them, which keeps a broken spring's pieces contained, not the door's weight, balance or safety.
How the visit goesThe door climbs with the left corner ahead of the right, then twists as it turns into the ceiling track. Looking up, the spring on the right side is stretched longer than its partner, with daylight showing between the coils.

How the visit goes
- 1
Hangers, brackets and what they are screwed into
Extension springs pull against whatever holds their back end, usually an angle-iron hanger bolted to the rear track support or lag-screwed into a ceiling joist. The technician checks that this anchor is tight, that the lag screws bite into wood rather than drywall or a split joist, and that the hanger has not bent under years of load. The bracket that carries the fixed pulley at the front of the track is checked the same way, along with the bottom brackets on the door that the lift cables pull on. An anchor that has loosened lets the spring's geometry drift, which is one reason a door slowly becomes uneven.

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.

Checking the balance yourself
You can confirm the springs are still doing their share without going near them. With the door closed and nobody in the opening, pull the opener's red release cord so the trolley lets go of the door. Lift the door by its handle to roughly hip height and take your hands away. A door on good springs stays about where it is; if it sinks to the floor the springs have weakened, and if it rises on its own they are pulling harder than the door weighs. Either way it is a call rather than a job for you. Reconnect the opener the way your manual describes, usually by running it once.

What affects the quote
- 1
Door weight and size
Spring rating follows the door's weight, and a wide insulated door or a wood door takes heavier springs than a light single. Weight and height together set the parts on the quote.

Time of the call
An evening, weekend or holiday visit costs the same amount as a weekday daytime appointment for an extension-spring replacement. The technician confirms the exact figure once the springs, cables and door weight have been checked on site.

Corroded fasteners
In an unheated garage the bolts through pulley forks and hanger brackets rust solid; freeing or cutting them and fitting new hardware takes time and shows in the parts list.

Extension Spring Replacement: questions
What are the early signs that the springs are wearing out?
The door starts to feel heavier when lifted by hand and the opener sounds as though it is working harder. Released from the opener, the door sinks from halfway instead of holding. With the door open, gaps show between coils that used to sit tight together, or one spring hangs longer than the other. Rust bloom on the coils and a squeal from a pulley round out the list. Any of these is a good time to call.
What information helps when I call?
Whether the springs run along the tracks or sit above the door; whether one is broken, hanging loose or just looks stretched; whether the door is closed, open or stuck partway and level or crooked; roughly how wide and tall the door is and what it is made of; and whether there is a cable running through each spring. A photo taken from inside with the door closed answers most of that at once.
Why does the opener get adjusted after new springs?
Because the door is now much lighter for the opener to move. Over the years, as the old springs weakened, the opener's force setting may have been turned up to keep the door going, and its travel limits were set against a door that sat differently on the floor. Left alone, that extra force would push the newly balanced door too hard. Resetting force and travel, then repeating the reversal tests, matches the opener to the door it now has.

What the census means at the door
61%
Older homes. About 61% of homes in Hamilton were built in 1980 or earlier, according to the 2021 Census.
Where most houses were built a generation or more ago, a good share of garage doors are still the originals: wood or early steel sections on extension springs. Those doors respond well to fresh pulleys, safety cables and a careful balance, and the technician carries the parts for them.
56%
A mix of homes. Single-detached houses make up about 56% of homes in Hamilton (2021 Census).
Where housing is varied, security needs vary too. A detached home wants its garage door closing fully and its interior door respected; a townhouse or condo wants old fobs and remotes cleared and the shared entrance working. We address whichever applies at each door.
