Winterization & Spring Startup in Houston

Seasonal shutdown and restart for Gulf Coast weather swings.

Houston winters are mild until they aren't. We insulate and drain vulnerable components before the first hard freeze, and in spring we recharge the system, check every head, and set a schedule for the growing season.

Signs you need this service

  • Hard freeze in the forecast
  • Backflow assembly exposed above grade
  • System has been off since last fall
  • Cracked PVC discovered after a cold snap

How we handle it

  1. 1 Shut down and drain exposed lines and assemblies
  2. 2 Insulate the backflow and above-grade piping
  3. 3 Spring recharge with slow pressurization
  4. 4 Full zone test and seasonal reprogramming

Available across the metro

We provide winterization & spring startup throughout Houston and the surrounding communities, including Houston, Katy, Sugar Land, Cypress, The Woodlands, Spring, Tomball, Pearland, Friendswood, League City, and more.

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.”
