As winter approaches in Northern Arizona, protecting your landscape isn’t just about covering plants—it’s also about making sure your irrigation system is ready for freezing temperatures. At Green Earth Landscaping & Construction LLC, we help homeowners and businesses avoid costly damage each year with proper, timely winterization.

What Is Winterization?

Winterization is the process of clearing water from your irrigation lines and preparing valves, backflow preventers, and exposed pipes to withstand freezing temperatures. Even a light overnight freeze can cause water trapped in the system to expand, leading to cracks, leaks, and springtime surprises.

Why It’s Important

Choosing Green Earth for your winterization service helps ensure:

  • Avoiding Expensive Repairs: A frozen backflow preventer or cracked valve assembly can cost hundreds to replace. Proper winterization eliminates that risk.

  • Preventing Hidden Leaks: Bursts underground often go unnoticed until spring irrigation starts back up—wasting water and causing landscape damage.

  • Extending System Life: Our technicians take a careful, systematic approach to protect your investment and keep your irrigation system functioning for years to come.

  • Peace of Mind: Once Green Earth winterizes your system, you’re prepared for every cold snap Northern Arizona throws your way.

What Our Winterization Process Includes

At Green Earth, winterization isn’t a one-size-fits-all approach. Depending on your system, our technicians typically:

  • Shut down the irrigation controller

  • Turn off the irrigation water supply

  • Drain the backflow preventer and main lines

  • Blow out irrigation zones with compressed air when appropriate

  • Inspect system components for wear or vulnerability

  • Secure and protect exposed pipes and backflow preventers

Our experience with local climate, elevation changes, and system types means the job is done thoroughly and safely.

When Should You Winterize?

Timing depends on elevation, but generally:

  • Cottonwood, Sedona, Verde Valley: Late October through mid-November

  • Flagstaff, Munds Park, Mountain Communities: Earlier in October

Green Earth schedules winterization appointments throughout the season to ensure your system is protected before the first hard freeze.
