Sprinkler Winterization & Freeze Protection in Allen, Plano & Frisco, TX

North Texas hard freezes can crack brass backflow preventers, split above-ground PVC risers, and ruin solenoid valves overnight. AAA Irrigation Service provides complete sprinkler winterization and freeze protection throughout Allen, Plano, Frisco, McKinney, Richardson, Wylie, Murphy, Lucas, and Fairview. Our TCEQ licensed technicians (LI0016993) shut down and protect your irrigation system before freezing weather hits—starting with our $95 seasonal inspection and checkup ($125 in Frisco), with any needed freeze blankets, sensor replacements, or repairs quoted upfront before work begins.

Frequently Asked Questions

Our complete system inspection and winterization checkup starts at $95 for Allen, Plano, McKinney, Richardson, Wylie, Murphy, Lucas, and Fairview ($125 in the Frisco extended service area). If your system needs a new insulated backflow pouch, wireless rain/freeze sensor, or valve repair, we provide an upfront quote for your digital signature before any extra work begins.

We locate and shut the main irrigation isolation valve (where accessible), relieve pressure in the upper assembly, drain and winterize the backflow preventer, inspect or install backflow insulation, test your rain/freeze sensor, check for weeping valves, and set your controller to Off or winter rain mode without erasing your programmed spring schedules.

In North Texas, the first freeze typically arrives between mid-November and early December, with the hardest freezes hitting in January and February. We recommend winterizing your sprinkler system in October or November before the first sudden cold front.
