Sprinkler Winterization Blowout & Spring Start-Up
High-CFM Compressed Air Blowouts & 100% Freeze Damage Protection in Aurora & Naperville, IL
Professional Execution for Long-Term Lawn Health
Sprinkler winterization (blowout) in Illinois involves purging all standing water from underground pipes, backflow assemblies, and sprinkler heads using high-volume commercial air compressors (50–100+ CFM) before freezing temperatures arrive. Because water expands by 9% when frozen, failing to winterize causes cracked PVC/poly lines, ruptured valves, and thousands of dollars in spring repairs. Montoya Irrigation guarantees 100% moisture removal across Aurora, Naperville, Oswego, and Chicagoland.

Frequently Asked Questions
When should I schedule my sprinkler blowout in Illinois?
We recommend scheduling your sprinkler winterization between mid-September and early November. In Chicagoland, the first hard freeze typically strikes by late October or early November. Scheduling early secures your preferred date on our consolidated neighborhood route before temperatures plunge below 32°F.
How much does a sprinkler blowout cost in Aurora and Naperville?
Residential sprinkler blowouts in Aurora and Naperville typically cost between $80 and $120 for standard residential systems (up to 6 to 8 zones). Larger estates, commercial properties, or systems with more than 8 zones are quoted based on zone count.
Why can’t I blow out my system with a standard home shop compressor?
Standard shop compressors deliver high pressure (PSI) but very low air volume (typically only 3 to 6 CFM). Purging water from hundreds of feet of underground pipe requires high air volume (50 to 100+ CFM) at safe, regulated pressure (50 to 65 PSI). Using a small compressor creates air pockets that bypass water, leaving trapped moisture that freezes and ruptures your pipes during Illinois winter.
What happens if I don’t blow out my sprinkler system before winter?
Trapped water expands by approximately 9% as it freezes. This expansion splits polyethylene lines, shatters PVC fittings, cracks solenoid valve manifolds, and destroys brass backflow preventers (RPZ valves). The resulting damage often costs between $500 and $2,500+ to excavate and repair the following spring.
Do I need to be home when Montoya Irrigation performs the blowout?
As long as your main sprinkler shutoff valve in your basement or utility room is turned off and we have outdoor access to your backflow valve and sprinkler heads, you do not need to be home. We will confirm completion and leave a service receipt.
