Sprinkler Blowout & Winterization in Fort Collins
Every line, head and valve cleared with compressed air before the first hard freeze, by the same local crew that repairs sprinklers all summer. Booked online in about two minutes.
Why Fort Collins sprinklers need a blowout
Water left in your lines freezes, expands and cracks pipes, valves and backflow preventers. A blowout pushes it out with compressed air so your system survives a Northern Colorado winter. One cracked backflow preventer costs more to replace than years of blowouts, and lateral line repairs in spring add up fast. Lotic Irrigation is locally owned in Fort Collins and has completed more than 5,500 jobs across Northern Colorado since 2020.

What a professional blowout covers
- Shut off the water supply and drain the backflow preventer
- Blow out every zone with a commercial compressor at the right pressure for your pipe type
- Confirm each head clears and valves are set for winter
- Set your controller to its off-season mode
- Note any heads, valves or leaks that need attention at spring start-up
- Winterize water features and pumps on request
Timing for Fort Collins
First frost usually arrives in early October and a hard freeze by mid-October. Book from late September through mid-October; once a hard freeze shows in the forecast, the last open slots go within a day or two.
If a freeze arrives before your appointment, shut off the water at the backflow and wrap the backflow preventer with a towel and a bucket until we get there. Read our guide to blowout timing in Fort Collins for more.

Sprinkler blowout questions
How much does a sprinkler blowout cost in Fort Collins?
Late-season pricing is in effect as of October 15, 2026: $164 for 1 to 6 zones, plus $10 for every 3 zones after that (7 to 9 zones $174, 10 to 12 zones $184). Commercial systems start at $188 for up to 8 zones.
When should I blow out my sprinklers in Fort Collins?
Before the first hard freeze, which usually arrives by mid-October. Late September through mid-October is the window, and the earlier you book the better the choice of dates.
Can I blow out my own sprinklers?
A shop compressor usually cannot move enough air volume to clear the lines, and too much pressure cracks fittings and heads. A professional blowout costs less than one repaired lateral line.
Do I need to be home?
Yes, usually. We need access to the shut-off valve and drain, which are typically in the basement. If everything is outside, leave us instructions when you book and you do not need to be there.
Do you also do spring start-ups?
Yes. Activation is $128 for the first 6 zones and includes a system check, head adjustments, leak repairs within the visit, and controller programming. See our sprinkler repair and installation page.
What if a line already froze?
Call us. We will assess the damage and repair it once the ground thaws. Backflow preventer replacement starts at $688.
Ready to winterize?
Book online in a couple of minutes, or call or text and we will get you on the schedule before the freeze.
