Service overview
Commercial Sensor Systems Are a Different Animal
A commercial opener needs monitored entrapment protection under UL 325: the operator continuously verifies its photo eyes and sensing edges are functional. If a device fails, the door may only close with constant-pressure control. The standard is stricter than residential because commercial doors are heavier, faster, and surrounded by people and forklifts.
Houston's warehouses punish these systems. Dock doors cycle dozens of times daily, forklifts clip the low-mounted photo eyes, and fine dust coats lenses within weeks. Add Gulf humidity corroding terminals, and you get the classic failure: a door that worked at 6 a.m. won't close by the afternoon shift. We rebuild with commercial realities in mind — guarded brackets, protected conduit, and industrial-rated photo eyes matched to your operator, including LiftMaster commercial lines and Overhead Door operators.
We schedule around your operation: nights, early mornings, and weekends keep dock time intact. Facility managers get photo records, test documentation, and a single point of contact for multi-door sites. For residential safety devices, see our safety sensor repair service; general faults are covered by sensor repair. We dispatch across Houston and surrounding areas, 24/7.

Use cases
Commercial Jobs We Handle in Houston
Where a stuck door costs real money.
Before: Dust-blinded retail doors
Two rear service doors reversed constantly; lenses were caked with dust. → Full cleaning, realignment, and a quarterly cleaning schedule.
Before: Failed safety audit
A warehouse failed its audit when sensing edges tested dead. → We replaced the edges, verified monitoring, and supplied test records for the file.
Problems we solve
Commercial Sensor Problems We Solve
Built for the abuse commercial doors take.
Forklift and impact damage
Low-mounted photo eyes are forklift magnets. We rebuild with steel guards and protected routing.
Unmonitored safety devices
Devices not monitored by the operator fail UL 325. We restore monitoring and prove it with tests.
High-cycle wear and dust
Constant cycling loosens everything; dust blinds lenses. We service the chain and set a cadence.

Customer reviews
What Our Customers Say
★★★★★
“They came at 9 p.m. so our docks never stopped, rebuilt the crushed brackets with guards, and gave us paperwork for our safety officer.”
★★★★★
“Three dock doors fixed in one night visit. The documentation alone was worth it — our audit passed clean.”
★★★★★
“Our sensing edges were dead and we didn't know it. They replaced them, proved the monitoring, and set up a maintenance plan.”
