Garage Door Cable Replacement in Chemong Heights
Your older door has springs along the tracks, and one cable has slipped off its pulley and dangles slack. The door lifts crooked and needs a shoulder to close, when it used to glide.
Garage Door Cable Replacement
In plain words
Two steel cables do the lifting on a sectional garage door. Each runs from a bracket at a bottom corner up to the counterbalance, and the springs pull on the door through them. Cable replacement renews that link. The technician secures the door, takes the tension off the springs, removes the worn or displaced cables, fits new ones matched to the door's height and weight, and re-tensions everything so both corners rise together. The result is a door that travels level again, closes flush to the floor, and asks the opener for the modest effort it was designed to give.
How the visit goesAfter years of slushy winters the cables look thinner near the bottom brackets, with rust streaks running down the door where they attach. The door still works, but the frayed wires catch your glove when you brush past.

How the visit goes
Torsion or extension, and which lift
The technician identifies the counterbalance before choosing parts. A shaft with drums above the header means a torsion system; springs stretched beside the horizontal tracks with pulleys mean extension. Then the lift type: standard lift on most attached garages, low headroom hardware where the ceiling is tight, and high lift where the door climbs well above the opening before turning. Each uses a different drum profile and a different cable length, and a double door of the same height may need a heavier cable than a single. Reading these details correctly is what makes the replacement cable wind evenly on the drum instead of overlapping.
Fitting cables that match the door
The replacement cables are chosen for construction, diameter and length rather than taken from a general bin. Residential doors use galvanized aircraft-type wire rope, and the length depends on the door height, the drum profile and the lift type; a high-lift door or a double door has its own requirements. The swaged stop on the new cable is seated in the drum slot and the cable is wrapped in the groove in the correct direction, leaving the drum on the side that leads straight down to the bracket. At the bottom, the loop goes over the bracket pin and is secured. The other side is fitted the same way.
A clear threshold
Most cables that jump their drums do so because the door came down on something. Keep the opening clear of bins, bikes and the snow shovel, and in winter clear the ridge of packed snow and ice that forms at the threshold before running the door. If the door does meet an obstruction and stops, leave it where it is rather than pressing the button again, since a second attempt is what turns a slack cable into a tangled one. The photo eyes near the floor should be clean and aligned so they catch anything in the path; a wipe with a soft cloth each season keeps them working.

What affects the quote
Same fees day, night or weekend
1One cable or the pair
Cables are normally renewed together, and the quote reflects two cables and the work of setting both sides level. Where one side was recently replaced, that is discussed on site.
2Drums that need replacing
Worn grooves, a cracked slot or a drum that has spun on the shaft mean a new pair of drums, which adds parts and a little time to the same visit.
3Impact damage to track or sections
A bumper strike often bends the track, a hinge or the bottom section as well as displacing the cable. Straightening or replacing those parts is quoted as separate work.
Garage Door Cable Replacement: questions
Why did the cable come off the drum?
A cable leaves its drum when it goes slack for a moment while the drum keeps turning. The usual reasons are the door closing onto an object or a ridge of ice so the bottom stops early, a spring that has lost tension or broken, or a drum whose set screws let it slip on the shaft. The technician finds which of these happened and corrects it so the new cable stays seated.
Can I lift the door by hand while a cable is off?
Leave it. With one cable slack the door is being carried on one side only, so it is unbalanced and may bind or drop unevenly when moved. The technician arrives with clamps and a method for taking the door's weight before anything is moved, and that is the moment to lift it. Until then a stationary door is exactly what you want.
Why should the bottom brackets never be loosened by hand?
The bottom bracket is where the cable attaches, so whenever the springs are wound it carries a share of the door's weight as tension. Loosening it while the counterbalance is loaded releases that tension all at once. Many manufacturers now fit tamper-resistant fasteners for this reason. The technician unloads the springs first, after which the bracket is just a piece of hardware to unbolt and replace.
