A spring visit follows a fixed order, so you know what to expect. The technician releases the opener, raises the door fully and clamps it, because an extension spring is at its slackest with the door open. Then both springs, the pulleys, cables, hangers and containment cables are inspected and the door is weighed. Old springs come off, new ones go on with containment cables threaded through, cables are routed over the pulleys and both sides are hooked at the same setting. The clamps come off, the door is balanced by hand, and only then is the opener reconnected, adjusted and put through its reversal tests.

Scene 1
The question the industry's own inspection checklist asks of every extension-spring door is whether each spring has a cable running through its centre, anchored at both ends. The technician checks for it on both sides, then checks its condition: a cable that is frayed, kinked, anchored to a loose screw or simply tied off to the hanger is not doing its job. Doors installed decades ago often have none at all, and doors that had a spring changed by a previous owner sometimes have one side fitted and one forgotten. Fresh containment cables go on with the new springs, and their anchor points are set into solid framing so that a spring which breaks stays on its cable.
Scene 2
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.
Scene 3
A standard extension spring is made for a set number of open-and-close cycles, commonly in the ten-thousand range, which on a door used four times a day works out to several years and on a door used twice a week to much longer. Springs age even when idle, as rust does its slow work in an unheated garage. The signs that the set is nearing the end are gradual: the door feels heavier by hand, the opener sounds as if it is working, the door drifts down from halfway, and gaps appear between coils when the door is open. Acting on those signs turns the next replacement into a planned appointment rather than a bang in the night.
What shapes the quoteRouge Valley Garage Door Co.
FeesSame any hour
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.
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.
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.

One of the springs beside the track is hanging loose at the front end, its pulley dangling, and a length of cable lies slack along the top of the door.
