Spring Repair
A snapped torsion or extension spring, a door that weighs a ton by hand, or a gap in the coil above the opening.

Garage Door Cable and Track Repair
Each lift cable winds onto a grooved drum as a torsion door rises, and its lower end anchors at a bottom bracket that holds it under full spring load. A slack cable is never a pull-it-tight job.
Valley wind
Why do canyon winds matter to your door's tracks?
Because the garage door is usually the biggest opening in a house, and DASMA notes that how the track and jambs fasten to the framing counts as much as the panels when wind pushes in and pulls out. Around Santa Clarita, that matters every fall and winter. Santa Ana season usually runs October through February, peaks in December, and the wind blows hardest below passes and canyon mouths, with gusts near 50 knots. DASMA also warns against bolting extra bracing onto a door yourself, since the added weight can overload springs and track. We replace frayed or snapped lift cables, reset drums, straighten or swap bent track, and fit new rollers and hinges.

What does a failing cable or track look like?
Usually a loose cable, a door sitting lower on one side, a roller out of its rail, or a rough, noisy run. Check your own Santa Clarita garage for the six signs below. If the door hangs crooked, stop running it.
Cable hanging slack
A cable dangling beside the door has come off its drum or lost tension. It is still tied to the spring system, so leave it alone.
Damaged cable
Visible damage on a cable or its bottom bracket is a stop sign. DASMA tells owners to leave both to a technician.
Door hangs crooked
A door sitting lower on one side is not something to force. Park the opener and have cables, drums and tracks checked together.
Roller out of track
DASMA's inspection checklist treats a roller leaving its track as a fail for a technician, not a job for a mallet.
Noisy run
Steel wheels on steel track are loud by nature. Dry open bearings add to it, since they need periodic oil.
Cracked hinge or panel
Hinges let the sections pivot into the overhead track. Cracks, fatigue or separating material in a section all fail an inspection.
Know the parts
Which part is failing on your door?
Match the symptom to the part: cables and bottom brackets carry spring load, while rollers, hinges and track guide the door along its path.
| Part | Its job | Under spring load | Warning sign | Who handles it |
|---|---|---|---|---|
| Lift cable and drum | Winds onto a grooved drum locked to the shaft by set screws | Yes | Frayed strands, slack line, door sitting uneven | A trained technician |
| Bottom bracket | Anchors the cable on the bottom section | Yes | Rust or a bent fitting at the floor corner | A trained technician |
| Roller | Rides in the track and carries each section | No | Grinding, wobble, a wheel out of the rail | Technician once it leaves the track |
| Hinge | Joins sections so they pivot | No | Cracks, loose fasteners, a section that dips | Technician or careful owner |
| Track | Vertical rail beside the jamb, horizontal rail overhead | No | Dents, bends, brackets pulling loose | A trained technician |
Our method
What we check before a door runs again
A door that has come off its track or lost a cable is still loaded by its springs, so the repair starts with making it safe, not with forcing it back. DASMA tells homeowners to leave brackets, cables and their mounting surfaces alone for that reason. Once tension is off, we look past the obvious failure. A roller that jumped its rail may have had help from a bent track, a loose bracket or a worn hinge. Fixing only the part you can see tends to bring the same call back to a Santa Clarita garage.
- Door secured before any work
- Both cables checked, not one
- Track fasteners tightened
- Rollers chosen for the door
- Level and balance tested
- Worn parts handed back

A track and cable visit
Getting a crooked door back on line
1
Call
We take track and cable calls across Santa Clarita. Say whether a cable is loose, the door is crooked or a roller is out, and send a photo.
2
Inspect
With the door secured, we check both cables, drums, bottom brackets, rollers, hinges and track fasteners, then give you a written price.
3
Repair
Spring tension comes off before a cable or bottom bracket is touched. Bent track is straightened or replaced, and rollers go back in their rails.
4
Run it
The door runs several full cycles. It has to sit level, hold still part-way open and pass the opener's reversal test before we pack up.
Repairs and installs
Garage door work in Santa Clarita
Six kinds of garage door jobs, each on its own page with the parts involved, the warning signs and what a visit looks like.
Opener Repair
Openers that hum without lifting, reverse for no reason, ignore the remote or stop halfway up the track.

Opener Installation
Chain, belt, screw and wall-mount openers fitted to the door you have, with the battery backup California requires.
More on Opener Installation →
New Door Installation
Steel, wood-look, carriage-style and glass sectional doors measured, hung, balanced and sealed in one job.
More on New Door Installation →
Track and Cable Repair
A frayed or slack lift cable, a roller out of the track, a crooked door or a bent section of rail.

Insulation and Seals
Insulated door options, new bottom rubber, side and top seals for garages that bake in a valley summer.

Cables and tracks
Stop using the door and keep cars and people clear of it. Leave the cable where it lies, since the other side is still under spring tension. Then call.
DASMA's own checklist says no. A roller out of the track is a fail for a technician, and the cables and bottom brackets right beside it hold full spring load. Forcing the door back can bend the track further or pull a cable off its drum.
Yes, because it still hangs on cables under full spring load while one or more rollers have lost their guide.
For most homes, nylon wheels run quieter because there is no metal-on-metal contact with the track. Roller life depends more on the bearings than on the wheel: sealed bearings need no oil, open ones need it now and then. Steel is the usual pick for heavy, busy commercial doors.
Only rollers with open bearings need periodic oil; sealed-bearing rollers do not, so check which kind your door has.
02
Rollers and hinges
Yes. Hinges are what let each section pivot as the door curves into the overhead track. DASMA's inspection checklist also looks for fatigue, cracks and separating material in the sections themselves. If several sections are failing at once, weigh the repair against a new garage door installation.
Not necessarily, but the two share one load, so both get checked. If the spring turns out to be the real failure, our garage door spring repair page covers it.
Anywhere in Santa Clarita, it covers both cables, the drums, bottom brackets, rollers, hinges and track, a written price, the repair, and a test run in which the door must sit level, hold part-way open and pass the opener's reversal test.
They can load it hard. DASMA notes a door in high wind must resist both inward push and outward suction, with the track and jamb attachment counting as much as the panels. Do not bolt extra bracing on yourself, though; the weight can overload springs and track.
It can be, if a bent rail makes the door drag, but a misaligned or blocked photo eye causes the same refusal, and our opener repair page walks through that side of it.
