New photo eyes, wired and verified
Garage Door Sensor Replacement in Houston, TX
Sometimes a sensor is beyond repair: the photo eye is dead, the housing is cracked, or the parts went obsolete years ago. Our garage door sensor replacement in Houston, TX swaps failed sensors for brand-compatible photo eyes — matched to your LiftMaster, Chamberlain, Genie, Craftsman, Overhead Door, Amarr, or Clopay opener — then wires, aligns, and safety-tests the system. Same-day service, most done in under an hour, within our $129–$299 typical range.

What's included
What's Included in Sensor Replacement
Replacement isn't just swapping boxes — new eyes must match your opener, sit at the right height, and pass the full safety test.
Failure Confirmation
We meter-test the old eyes with wiring and power verified good — you never pay for new sensors when a repair would do.
Compatible Parts
Photo eyes matched to your opener's brand and series — LiftMaster, Chamberlain, Genie, Craftsman, Overhead Door, Amarr, or Clopay — from truck stock.
Mounting & Wiring
New brackets set level at the correct height; low-voltage wiring run cleanly with corrosion-resistant terminals.
Alignment & Safety Test
Beam centered and locked, then full open, close, and auto-reverse testing before we call it done.
Service overview
When Repair Isn't Enough Anymore
Most sensor faults are repairable — a realignment, a wiring splice, a cleaning. But photoelectric eyes live a harsh life: inches off a concrete floor, in Houston heat and humidity, taking bumps for years. Eventually some fail outright. The sign is a dead LED on one eye while wiring and power test good — or a cracked housing that let moisture onto the circuit board.
Age is the other factor. On 15-plus-year-old openers, exact replacement eyes may be discontinued — but compatible units exist for most major series, and our trucks stock the common ones. What we won't do is force a generic "universal" sensor onto an opener it wasn't designed for; mismatched eyes cause the phantom reversals you're trying to escape. One honest caveat: if no compatible sensors exist for your opener, the safe answer may be a new opener — and we'll show you the math instead of selling a doomed fix. Unsure which situation you're in? Our troubleshooting guide narrows it down, or call (281) 301-2494 for on-site diagnosis.
How we workWe prove the old eyes are dead, match new ones to your opener, and test everything.
The service timeline
The Replacement Process
Five steps from dead sensors to a fully verified safety system.
Diagnose & Confirm
We verify power and wiring first, then meter-test each eye. Replacement only proceeds when the eyes are proven faulty.
Match the Parts
We identify your opener's brand and series and select compatible eyes — from truck stock in most cases.
Approve the Price
The exact total — parts plus labor, inside $129–$299 — before the old sensors come off the wall.
Install & Wire
Old eyes removed; new brackets mounted level at the correct height with corrosion-resistant terminals.
Align & Safety-Test
Beam centered until LEDs burn steady, then full open, close, and auto-reverse tests.
Tools & methods
What Drives Replacement Cost
Three factors decide where your replacement lands in the range — confirmed before work starts.
Sensor Compatibility
Common-brand eyes are straightforward; rare series may need a compatible substitute — priced before you commit.
Wiring Condition
Nicked, corroded, or chewed low-voltage runs get replaced during the swap so new eyes get clean power.
Mounting Hardware
Rusted or bent brackets get replaced — a new sensor on a wobbly bracket is a callback waiting to happen.
Labor, Itemized
Parts and labor listed separately. Most replacements take under an hour.
Use cases
Replacements We Do Across Houston
When the eyes are done, they're done — here's what that looks like.
Before: Cracked Housing, Moisture Inside
A rock cracked the receiver housing; Houston humidity finished the job — months of intermittent faults. → New sealed eyes, fresh mounts, steady lights.
Before: Obsolete Parts, Honest Answer
A 20-year-old opener's sensors were discontinued with no compatible substitute. → We showed the math and laid out opener options instead of selling a doomed fix.
Problems we solve
When Replacement Is the Right Call
We replace when the evidence says repair won't hold — never as an upsell.
Dead photo eye
No LED with good wiring and power means internal failure. New compatible eyes restore the beam.
Physically damaged sensors
Cracked housings and moisture-damaged boards can't be realigned back to life. We swap the pair.
Obsolete parts
Originals discontinued? We source compatible replacements — or give you the honest math if none exist.

Do replacement sensors have to match my opener brand?
They must be electrically compatible. We install brand-compatible photo eyes for LiftMaster, Chamberlain, Genie, Craftsman, Overhead Door, Amarr, and Clopay — matched to your unit, not generic one-size parts.
How much does garage door sensor replacement cost in Houston?
Most replacements land in our $129–$299 typical range, parts and labor included. The $79 diagnostic is waived with completed service; first-timers save $50 with code FIRST50.
How long does a sensor replacement take?
Usually under an hour — remove the failed eyes, mount and wire the replacements, align the beam, and run full safety tests in one same-day visit.
Will new sensors work with my older garage door opener?
In most cases, yes — as long as compatible photo eyes are still made for your opener's series. If parts are truly obsolete, we'll tell you honestly and discuss options.
