Irrigation Winterization

Professional Irrigation Winterization in Woodbury, Rosemount & Stillwater, MN, and Hudson, WI

Protect your irrigation system from freeze damage with our comprehensive winterization service

When winter temperatures drop below freezing in the Twin Cities, any water remaining in your irrigation system can expand and cause catastrophic damage to pipes, valves, and sprinkler heads. At LNG Landscapes, we provide thorough irrigation winterization services that completely prepare your system for Minnesota and Wisconsin winters. Our technicians follow a detailed six-step process to remove all water from your system and protect every component from freeze damage.

We serve residential and commercial properties throughout Woodbury, Rosemount, Stillwater, and Lakeville in Minnesota, plus Hudson in Wisconsin. Our winterization services run from September through Thanksgiving, ensuring your system is protected before the first hard freeze arrives.

The Critical Importance of Professional Winterization

Minnesota winters are unforgiving to irrigation systems. Water left in pipes, valves, or sprinkler heads will freeze and expand, creating pressure that can burst pipes and crack expensive components. The damage often goes unnoticed until spring startup, when you discover broken lines, damaged valves, and malfunctioning sprinkler heads.

Professional winterization isn’t just about draining water—it’s about protecting your investment. A properly winterized system will fire up reliably each spring, while a neglected system often requires costly repairs. Our expert team understands the specific challenges of Twin Cities winters and follows industry best practices to keep your system safe.

Our Complete Winterization Process

LNG Landscapes follows a meticulous six-step winterization process that ensures every drop of water is removed from your irrigation system:

• Turn off the main water supply to prevent additional water from entering the system
• Close the valve to the backflow device to isolate the system from your home’s water supply
• Blow out all lines with compressed air to remove water from pipes, valves, and sprinkler heads
• Protect the backflow preventer by turning all valves to 45-degree angles to prevent cracking
• Shut down the controller to prevent accidental activation during winter months
• Protect above-ground components with appropriate coverings and insulation

This comprehensive approach addresses every component of your irrigation system. Our technicians use professional-grade compressed air equipment to ensure complete water removal, and we protect vulnerable above-ground components that could be damaged by ice and snow.

Timing Your Winterization Service

We begin scheduling winterization services in September and continue through Thanksgiving or until the first hard freeze arrives. The key is completing the service before sustained freezing temperatures hit your property. In the Twin Cities area, this typically means having your system winterized by mid to late November.

Early scheduling ensures availability during our busy season. Property owners who wait until the last minute often find themselves scrambling to book service before dangerous temperatures arrive. Our team monitors weather forecasts closely and will contact clients if an early freeze threatens the area.

For commercial properties with multiple zones or complex systems, we recommend scheduling even earlier to allow adequate time for thorough winterization of all components.

Spring Startup Service Available

When spring arrives, LNG Landscapes provides complete irrigation startup services to bring your system back online. Our startup process includes closing drain valves, preparing the backflow preventer, pressurizing the system, testing each zone, and programming your controller for the new growing season.

We also offer comprehensive irrigation repair and maintenance services to address any issues that arise during startup or throughout the growing season. Common repairs include fixing broken sprinkler heads, replacing leaking zone valves, and troubleshooting controller problems.

Commercial Winterization Services

LNG Landscapes provides irrigation winterization for commercial properties including HOAs, retail plazas, healthcare campuses, and multi-site portfolios. Commercial properties often have complex zoning systems that require specialized attention during winterization.

Our commercial clients receive direct access to a dedicated manager, live SMS updates with service logs and photos, and the peace of mind that comes from working with a fully insured, MNLA-affiliated contractor. We understand the importance of protecting valuable irrigation investments across multiple properties.
