Bent Track: Repair or Replace

A bent track is the one garage door fault a homeowner can usually see, and the one most often patched rather than fixed. The line between the two is drawn at Garage Door Track Repair Orange County, CA afvdayodyssey by where the damage sits and what shape the steel is left in, because the same dent in two different places on a door in Orange County calls for two different answers.

Three Kinds of Deformation

A dent is a local depression that leaves the channel width intact. A crush is a squeeze that narrows the channel so a roller cannot pass. A twist is a rotation along the length of the rail, which is the hardest to see and the most damaging, because the wheel is then asked to run at an angle for the whole of that run.

What Can Be Straightened

A shallow dent in the vertical run, away from a splice and away from any bracket, can be dressed back with a hammer and a block and left in service. The test is not how it looks but whether a wheel passes through it under hand pressure with the door disconnected and without a catch. Anything in the curve should be treated as scrap, since a radius has to be geometrically right and there is no way to verify a hand corrected one.

What Has to Come Out

Crushed lengths, anything with a crack radiating from a bolt hole, any twist, and anything a vehicle hit hard enough to move the bracket behind it. Galvanised steel that has been bent and bent back has lost its coating at the fold, and that is where rust starts in a coastal garage, so a repaired rail in salt air has a shorter life than a new one even when the shape is right.

Ordering the Right Part

Track is not universal. The gauge, the channel width, the radius of the curve and the bolt spacing all have to match what is already there, and mixing a two inch system with a one and three quarter inch one is a common and expensive mistake. Photograph the splice plate and measure the channel opening before ordering anything.

The Cause Comes First

Replacing a rail without finding what deformed it guarantees a second call. A seized roller, a cable off its drum, a broken spring that the door was run on, or a loose bracket will all bend fresh steel just as readily as they bent the old. The replacement is the last step of the job rather than the first.

After the Swap

A new length changes nothing about the alignment on its own. The rail has to be set plumb, the spacing to the door face checked at top and bottom, the splice bolts tightened, and the balance rechecked before the opener is reconnected. A door that ran badly before will usually run badly afterward if that last part is skipped.
