Controller & Timer Repair in Houston

Programming, wiring, and replacement of irrigation controllers.

Most 'system failures' are really controller problems: a blown output, a lost program, or a bad common wire. We test each station output, correct the field wiring, and reprogram the schedule around Houston's rainfall pattern and your soil type.

Signs you need this service

  • Display is blank or throwing a fault code
  • One station never fires while the rest work
  • The system runs at random times
  • Programs erase every time the power blinks

How we handle it

  1. 1 Station-by-station output testing at the terminal strip
  2. 2 Field wire and common continuity check
  3. 3 Repair or replace the controller as needed
  4. 4 Program a seasonal schedule and show you how to adjust it

What customers say about our work

4.9 average from 12 customer reviews
“Two zones had quit on us and another company told us the whole manifold had to be replaced. The tech from Reliable traced it to a bad solenoid and a nicked wire, fixed both, and ran every zone with me before he left. Straight answers the whole way through.”
Marcus D. Katy, TX · Valve Repair & Replacement · June 9, 2026
“Our water bill nearly doubled and we could not find the cause. They located a cracked lateral under the side yard in about forty minutes, repaired it, and put the sod back so neatly you cannot tell where they dug.”
Priya S. Sugar Land, TX · Leak Detection & Repair · May 28, 2026
“Eleven heads replaced and every arc reset. The shade zones under the oaks were drowning and the sunny strip was burning up — they rebalanced the whole thing and the lawn evened out within two weeks.”
