Start with what the door is doing
You don’t need to know the name of the part. A good description of the symptom usually narrows the problem to two or three suspects before we even open the truck. Here is how the most common complaints tend to sort out.
| What you notice | Usual suspects | What the fix involves |
|---|---|---|
| Opener hums, door lifts a few inches and stops | Broken torsion spring | New spring matched to the door’s weight, then a balance test |
| Door hangs lower on one side | Cable off the drum or a frayed cable | Re-hang or replace cables, inspect drums and bottom brackets |
| Door closes, touches the floor, and goes back up | Photo-eyes out of line, or close-limit set too far | Realign sensors, reset travel and force |
| Loud bang, then nothing works | Spring failure, sometimes a snapped cable | Replace the failed part, check everything it was attached to |
| Shaking or binding partway up | Worn rollers, loose hinges, track out of plumb | Replace rollers, tighten or replace hinges, set the track |
| Works in July, struggles in January | Stiff grease, weak springs, seal frozen to the slab | Clean and re-lubricate, rebalance, replace the bottom seal |
The table is a starting point, not a diagnosis. Two doors with the same symptom can have different causes, which is why we look at the whole system before quoting anything.
How we work through a repair
Every visit begins the same way. We disconnect the opener and lift the door by hand. A healthy residential door should rise with one hand and stay put when you let go at waist height. If it drops or shoots upward, the springs are either tired or wound wrong, and nothing else on the door will behave until that’s sorted.
From there, we follow the load path: springs, the torsion shaft and bearings, drums, cables, bottom brackets, then rollers, hinges, and track. The opener comes last. That order matters. Openers get blamed for a lot of problems they didn’t cause, and replacing a motor on a door that’s 40 pounds out of balance just gives you a new motor that wears out early.
Once we know what failed and why, we explain it in plain terms and give you a price before any work starts. If there’s a cheaper fix that will hold and a more thorough one that will last longer, you’ll hear both.
Repairs we handle most often
Franklin has a lot of attached two- and three-car garages built from the 1970s through the 2000s, and the doors on them tend to wear out in a predictable order.
- Springs Torsion springs above the door and extension springs along the tracks. See our spring repair page for the details.
- Cables and drums Frayed strands, cables that jumped the drum, and rusted bottom brackets. More on our cable repair page.
- Rollers and hinges Cracked nylon, seized bearings, and hinges that have worn their pin holes into ovals.
- Tracks Bent verticals from a bumper tap, loose lag screws, and horizontal track that has drifted out of level.
- Weather seals Bottom rubber, the retainer that holds it, and the vinyl stops along the sides and top.
- Opener issues Stripped gears, dead remotes, sensor wiring, and logic boards, covered on our opener repair page.
Repair or replace?
Most of the time, repair is the right call. Steel sections that are still straight and rust-free will outlast several sets of springs and rollers. We lean toward repair when the damage is limited to hardware, the sections are straight, and parts are still made for that model.
Replacement starts to make sense when several things pile up at once: rust eating through the bottom section, cracked stiles where the hinges mount, a discontinued panel design, or a wood door that has taken on water and gained weight. If the repair estimate creeps past roughly half the cost of a comparable new door, we’ll say so and let you decide. We don’t have a quota of doors to sell.
