Michigan Sprinkler Winterization Specialists
When freezing temperatures arrive in Michigan, water remaining inside an underground irrigation system can freeze, expand and damage sprinkler pipes, valves, fittings and exposed plumbing.
A professional sprinkler winterization, also called a sprinkler blowout, helps remove water from irrigation lines before winter weather creates the potential for expensive damage.
At WinterizeSprinklers.com, we focus on one important seasonal service: helping homeowners prepare their underground sprinkler systems for winter.
Our winterization services are performed by Metro Automated Sprinklers, an established Michigan irrigation company serving the region since 1993.
Whether you have a small residential sprinkler system or a larger multi-zone irrigation system, professional winterization is an important part of protecting your investment.
Important: A sprinkler system can suffer freeze damage even when the controller is turned off. Shutting down the timer does not remove water trapped inside irrigation plumbing.
What Is Included in a Professional Sprinkler Blowout?
Proper sprinkler winterization involves more than simply connecting an air compressor. Different irrigation systems have different plumbing arrangements and winterization needs.
Commercial Compressor Blowout
Commercial-grade air compressor equipment is used to help clear water from underground irrigation piping.
Individual Zone Winterization
Sprinkler zones are operated individually to remove water from the irrigation lines while following appropriate equipment and system limits.
Valve & Plumbing Attention
Accessible valves, drain points and exposed irrigation plumbing are addressed as appropriate for the specific system configuration.
Backflow Assembly Considerations
Exposed backflow prevention assemblies can be vulnerable to freezing. Proper winter preparation depends on the assembly and installation.
Seasonal System Shutdown
The irrigation controller and system are placed into the appropriate winter shutdown condition.
The exact procedure depends on system design, accessibility and equipment. Winterization reduces freeze-damage risk but cannot guarantee that every component is free of water or prevent all damage.
Why Professional Sprinkler Winterization Matters
Michigan winters regularly bring temperatures below freezing. Exposed irrigation components may be especially vulnerable.
- Helps protect underground irrigation pipes
- Reduces the risk of frozen sprinkler valves
- Helps protect exposed irrigation plumbing
- Reduces the likelihood of avoidable spring repairs
- Prepares the irrigation system for winter shutdown
- Supports a smoother spring startup
Improper compressor pressure, airflow or operating time can damage irrigation components. Professional technicians use methods appropriate to the system rather than simply applying maximum pressure.
When Should You Winterize Sprinklers in Michigan?
In Southeast Michigan, homeowners typically schedule sprinkler winterization during September and October, with service continuing into November when weather and system conditions permit.
The safest approach is to arrange winterization before freezing weather threatens exposed irrigation plumbing.
Schedule Early: Fall appointments are seasonal, and available service dates can become limited as colder weather approaches.
Waiting until a freeze is forecast can leave little time to schedule professional service.

A few simple preparations can help your irrigation technician complete your sprinkler blowout efficiently.

Frequently Asked Questions About Sprinkler Winterization
What is a sprinkler blowout?
A sprinkler blowout is a winterization procedure that uses controlled compressed air to remove water from irrigation piping and sprinkler zones before winter.
Do underground sprinkler systems need winterization in Michigan?
Underground irrigation systems in Michigan are generally winterized to reduce the risk of water freezing inside pipes, valves and exposed plumbing.
When should I schedule my sprinkler winterization?
September and October are common scheduling months in Southeast Michigan. The goal is to complete winterization before damaging freezing conditions. Weather and appointment availability vary.
How much does a sprinkler blowout cost?
Metro Automated Sprinklers' published 2026 residential winterization rate was $57 for up to six zones, $8 per additional zone and a $2 diesel fuel surcharge. Contact us to confirm current pricing.
Can I winterize my own sprinkler system?
Some homeowners attempt winterization themselves, but improper compressor pressure, airflow or procedures can damage irrigation equipment. Professional service is recommended when you are unfamiliar with the system's requirements.
Will turning off my sprinkler controller prevent freeze damage?
No. Turning off the controller does not remove water trapped inside irrigation piping and components. The water supply and system plumbing also need appropriate winter preparation.
Can a backflow preventer freeze?
Yes. Exposed backflow assemblies can be damaged when water freezes inside. Proper winter preparation depends on the assembly design and installation.
How long does a sprinkler winterization take?
Service time depends on the number of zones, system design, access and plumbing configuration. Larger or more complex systems can require additional time.
Can you winterize a sprinkler system after freezing weather?
Service may still be possible if the necessary components are not frozen or damaged. Never force compressed air through frozen or obstructed components. Contact a professional for guidance.
