Garage Door Sensor & Safety Eye Repair in Houston
If your garage door reverses for no reason, won’t close, or blinks its sensor lights, the safety sensors are usually the cause. We diagnose and fix sensor issues fast so your door closes reliably again.
Signs You Need This Service
- The door reverses right before it touches the ground
- The door won’t close at all and the opener light blinks
- The sensor lights are off, flickering, or one is solid and one isn’t
- Sensors look knocked out of alignment or physically damaged
- The door closes fine at night but not during the day (sun interference)
How We Handle It
Test the sensors
We check alignment, wiring, and power at both sensor units.
Fix or replace
We realign, clean, rewire, or replace the sensors — whichever actually solves it.
Confirm safe operation
We test the full close cycle to confirm the door closes reliably and reverses correctly when it should.

Frequently Asked Questions
Why does my door only have trouble closing sometimes?
That’s usually direct sunlight hitting one sensor, or dirt/misalignment that shows up intermittently. We can normally resolve it in one visit.
Is it safe to keep using the door if the sensors aren’t working?
We don’t recommend it — the sensors are a core safety feature that prevents the door from closing on a person, pet, or object. Get it looked at before regular use.
Door Won’t Close? It’s Probably the Sensors.
Most sensor issues are fixed same-day.
