The Symptom
The door hangs crooked in the opening, or one side rides higher than the other. Sometimes it stops halfway and won't go up or down. Sometimes a roller has popped clean out of the track and the panel is leaning on the frame. If you try to force it with the opener, you can bend the track further or pull the bottom bracket loose from the panel.
The cause is almost always mechanical, not electrical: a roller wheel that's worn round instead of the shape it should be, a bent track rail, or a cable that's slipped off its drum. On a two-car door, an off-track panel on one side often means the lift cable on that side let go or the torsion spring lost tension unevenly, so the door is being pulled by only part of its hardware.
Don't keep hitting the opener button once you see a gap between the roller and the rail. That's how a $150 track adjustment turns into a $500 panel replacement. Kill power to the opener, prop the door if it's partway open, and call before you touch it further.
What You Pay
A straightforward off-track fix - reseating rollers, squaring the track, tightening brackets - is a short job in most cases. Cost climbs if the track itself is bent (it usually needs replacing, not straightening back true) or if a cable or spring failed alongside the roller and caused the problem in the first place. We won't know which of those you've got until we look at it, and we're not going to quote a number over the phone based on a description, because a bent track and a popped roller look the same from the driveway but cost very differently to fix.
We don't have a fixed price to publish here since the range depends on what's actually damaged. What we can tell you: if your house is original to its 1960s or '70s build and you've never replaced the track hardware, budget on the higher end of whatever range you're quoted, because you're likely looking at track and roller replacement together, not just an adjustment.
Stocked Parts
We carry the roller and track hardware that matches the door generation common across this area's 1938-1989 housing stock - standard 2-inch and 3-inch track sections, sealed-bearing rollers in the sizes that fit the older stamped brackets, and the mounting hardware for both. That covers most off-track calls without a special order.
Where we run into a wait is with less common track widths on older custom doors, or opener-specific mounting brackets tied to a particular manufacturer's rail system. Those sometimes have to be ordered in, and we'll tell you upfront if that's the case rather than let you assume it's a same-visit fix.
