Safety sensors and reversal
When a door reverses unexpectedly or stops short of closing, we test the photoelectric sensors and the contact-reversal function first. Often the cause is a sensor that has been knocked out of aim or has failed. We tell you which it is before anything gets replaced.
Safety sensor repair or replacement runs $125 to $300. Once the work is done, we run the door through a full open and close to confirm it travels the whole way and reverses the way it should.
Tracks, rollers and cables
If the door drags or jerks, we look at the track and the rollers together, because a bent track chews up rollers and worn rollers pull on the track. We install nylon rollers when we replace them. Track replacement also runs $125 to $300.
If a cable is damaged, we replace it, then run the door to make sure it moves smoothly. A door that still shudders after the swap gets more diagnosis before we call the job finished.

Price and approval before work starts
On the phone we can give you the typical range for sensor or track work, which is $125 to $300 for either. The exact number is confirmed once we've seen the door, since a loose sensor and a dead one are different jobs.
We explain your repair and replacement options and get your approval before we start. If we find something else along the way, we stop and go over it with you before doing anything further.
Getting Started Is Simple
For work like this, the work covers:
- For a new installation, prepare the frame and mount the vertical and horizontal tracks.
- Install the spring, pulley, and cable system, secure the door sections, and connect the opener.
