What you are seeing
Most track repairs start with a noise or a sideways lean, and homeowners describe it like this.
- A roller popped out and the door sits cockeyed in the opening
- A kink in the track where a bumper or a mower clipped it
- Scraping or a thunk at one spot each time the door moves
- The track wobbles or pulls away from the wall while the door runs
- The horizontal tracks sag toward the back of the garage
- Rust flakes and a rough patch at the bottom of a vertical track
What we do on a track repair visit
Track work starts by locking the door down and finding what pushed the steel out of line, and only then do we bend, cut or replace anything.
Make the door safe before anyone touches the track
We clamp the door in place, unplug the opener, and clear the area below it, because a door with rollers out of the track is unstable and the springs above it are still wound. If a cable has come off its drum or the door is wedged crooked, that gets handled first, because releasing the wrong part can bring the whole door down.
Find what bent it
Track rarely bends on its own, so we look for the cause: a car or mower strike, an opener that kept pushing after a roller jumped, a frayed cable that let one side drop, a cracked hinge that let a roller wander, or brackets working loose in soft wood. Fixing the steel without fixing the cause means the same problem in a few months.
Straighten a gentle bend, replace a crease
A shallow bow in a horizontal run, or a flared edge where a roller pushed out, can usually be worked back and checked with a straightedge. A crease, a twist, a split seam or a crushed curve gets replaced, because hammered steel leaves a hard spot the rollers bump over. We match the new piece to the existing width, gauge and radius.
Re-anchor brackets into solid wood
Jamb brackets hold the vertical track to the framing with lag screws, and in an older garage those screws are often spinning in soft or split wood. We probe the jamb, move the bracket to sound wood or add a backing block, and replace rear hangers that have pulled away from the ceiling. A track is only as straight as whatever holds it.
Align both sides and run the door by hand
Vertical tracks are set plumb with even spacing from the door edge, so rollers neither bind nor ride out of the channel. The horizontal runs are checked for level and for parallel, each curve meets the straight track without a step, and the door travels its full height by hand before the opener is reconnected.
Check what the derailment damaged
A door that left its track usually hurt something else on the way, so we look over every roller stem, the hinges on the affected side, the top brackets and the struts. Then the opener goes back on, force and travel get reset, and we confirm the door backs off when it meets an object and when the photo eye beam is blocked.
Vertical, horizontal and the curve between: where each part fails
Each part of the track fails in its own way: vertical track at the bottom, the radius where the door turns, and horizontal track at the back.
The vertical tracks stand beside the opening on jamb brackets. Their lower ends sit closest to the slab, so they take bumper hits and standing water. In the northern blocks of Kenton beside the Columbia Slough, or near Johnson Creek in Lents, where flooding keeps coming back, that is where we look for rust first.
The radius is the curve where every section changes direction, so a crushed or opened-up curve makes the door hesitate or jump at the same height each time. The horizontal tracks hang from the ceiling on rear hangers, and a failed hanger is where sagging starts.
Old garage framing and track brackets that will not stay tight
In older detached garages, loose track often traces back to the framing rather than the steel, because lag screws cannot hold in jamb wood that has gone soft.
The small single-car garages behind early-1900s houses in Arbor Lodge, Concordia and Sellwood can have jambs that have taken decades of splash off the slab. Lag screws work loose, someone moves a bracket an inch to find fresh wood, and the track drifts out of plumb.
Portland weather keeps that wood close to the danger line. The USDA Wood Handbook puts outdoor wood here at about 16.5 percent moisture in January and 17.4 percent in December, and wood kept below 20 percent does not decay. A jamb bottom that catches splash on top of that baseline is where rot tends to start.
When a jamb is too far gone for a backing block, we show you before any new track goes on and quote the framing repair separately.
Backed into the door? What to do about a bent track
Keep the door where it stopped, unplug the opener, and take photos before anything moves, since one car strike can bend the track, the bottom section and the struts at once.
Running the opener after an impact is how a bent track turns into a door on the floor. The rollers jam at the kink, the opener keeps pushing, and the door twists out of its track. If the car is shut inside, mention it on the phone so we come ready to free it.
On Southwest Hills lots, where steep driveways and tight turning room are normal, clipping the edge of the opening is an easy mistake. A low hit usually lands on the vertical track near the bottom bracket, and that bracket holds cable tension, so it is a job for us rather than a hammer.
What changes the price
The posted price covers straightening, realigning and re-anchoring the track you have, and new steel or extra repairs are added on top.
- Replacement track sections, priced per piece
- Damage on both sides, or a crushed radius section
- New rear hangers tied into ceiling framing
- Backing blocks or jamb repair where the wood will not hold a lag screw
- Rollers, hinges or a bottom bracket damaged when the door left the track
- Low-headroom kits, or heavier track for wood and oversized doors
When a repair stops making sense
Track repair stops making sense only when the damage reaches the door itself, because track is among the more forgiving parts.
When a car strike has creased two or more sections, bent the struts and twisted both tracks, the repair can approach the cost of a new door, and you see both numbers before deciding. A door rusted through at the bottom along with its track gets the same side-by-side quote.
A single bent horizontal run on a sound door is a straightforward repair, and nobody should be talked into a new door over it.
track repair: common questions
Can a bent garage door track be hammered back into shape?
Sometimes, if the bend is a gentle bow or a flared edge and the steel is not creased. A crease, twist or split seam stays stiff after hammering, and rollers bump or jump there every time the door runs. We straighten what will run true, check it with a straightedge, and replace the rest.
Do you replace one side of the garage door track or both?
Usually just the damaged side, as long as we can match the width, gauge and radius of the other one. Both sides get replaced when the profiles cannot be matched, when both are rusted at the bottom, or when an impact bent the pair. Mismatched track makes the door run unevenly and wears the rollers on one side.
Why does my garage door track keep coming loose from the wall?
Most often the lag screws are spinning in soft, split or rotted jamb wood, and tightening them again rarely holds for long. We move the bracket to sound framing or add a backing block so the screws bite into solid wood. We also check whether a worn roller or hinge is shaking the track loose.
Is it safe to keep using a garage door with a bent track?
No. A roller can jump out at the bend, and a door that leaves its track can twist, jam or fall. Stop running the opener, keep the door down if possible, and keep people and cars clear of it. If it is stuck open, ask us how to secure it until we get there.
What is a low-headroom track kit, and does my garage need one?
It is a track kit that lets a sectional door turn in less space above the opening than standard track needs. Garages with a beam, duct or low ceiling right above the door sometimes need one. We measure the headroom before quoting, and in many garages standard track with the right radius still fits.
Can new track fix a garage door that sits crooked when closed?
Only if the track caused it. A door that hangs low on one side is more often a slipped or frayed lift cable, a worn drum or a spring problem, and new track will not level it. We find the cause first, and if the track is fine, we say so and fix the part at fault.
Why do the horizontal tracks on my garage door sag toward the back?
Usually a rear hanger has bent, pulled out of a ceiling joist, or was fastened to drywall or a thin board instead of framing. The back of the track drops, the door binds near the top of its travel, and the rollers start wearing the track. We rebuild the hanger from perforated angle, tie it into solid framing and re-level both runs.
