About Sprinkler Winterization

Sprinkler systems are a considerable investment and one worth protecting. By blowing out the sprinkler system with compressed air each fall you can help prevent damage to its lines, valves and fittings. For northern climates, most winterizations are performed in October.

Frequently Asked Questions

The most asked questions about sprinkler winterization services

What is sprinkler winterization?

Sprinkler winterization, also called a blowout, involves using compressed air to remove all water from your irrigation lines, valves, and heads before freezing temperatures arrive. This prevents costly damage to pipes and backflow devices over winter.

How much does sprinkler winterization cost?

The average sprinkler winterization costs $80. Pricing depends on the number of zones and system size. You can use LawnGuru to easily compare quotes from the top landscapers working in your neighborhood.

Why is winterizing my sprinkler system important?

If water is left in your sprinkler lines, it can freeze, expand, and crack pipes or fittings. A proper blowout ensures your system is completely dry and protected, saving you from expensive repairs in the spring.

When should I schedule sprinkler winterization?

Ideally, schedule your blowout before the first hard freeze, usually between mid October and mid November, depending on your region. Once nightly lows consistently dip below freezing, it’s time to winterize.

What’s included in the service?

Most services include:


  • Connecting an air compressor to the system
  • Blowing out each zone until no water remains
  • Draining the backflow preventer and confirming the system is fully dry

Do I need to be home during the service?

Not usually. As long as your irrigation system and backflow are accessible outdoors and your provider has instructions for shutoff valve location, you don’t need to be home. If the shutoff is inside, please turn off the water to the irrigation system ahead of your providers arrival or be home to assist.

How long does the blowout take?

Most residential systems take 15 - 30 minutes depending on the number of zones. Larger or complex systems may take slightly longer.

What happens if I don’t winterize my sprinklers?

Water left in pipes can freeze and cause cracks, leaks, or broken fittings often costing hundreds or even thousands to repair in spring. Winterization is a simple preventive step that protects your entire irrigation investment.

Do you offer spring startup service too?

Yes! In spring, you can book a sprinkler startup service to reopen valves, pressurize lines, check for leaks, and adjust sprinkler heads for even coverage.
