Oct 1
Watering season is over
Denver Water's board ruled that lawn watering and all spray irrigation must stop after Sept. 30, 2026. Willows Water District set the same date. There's no reason left to keep your system charged.1
Denver Water ended lawn watering Oct 1
Your sprinklers are off. The water is still in the lines.
Denver's average first freeze is October 7. Pick your neighborhood's route day, we text you an arrival window, and every zone gets blown out before the cold gets to it. From $100 for 1 to 4 zones, and you see your price before we book.

Why this week, not "sometime in October"
Three dates decided this for you.
Most years you could wait for the first cold snap. This year the season ended early, and a system that's off is just a pipe full of standing water.
Oct 7
Denver's average first freeze
That's the average. The National Weather Service has recorded a first freeze as early as September 8. One clear, cold night is all it takes for exposed parts.2

How much water grows when it freezes
Pipes, valves and your backflow preventer don't grow with it. A $100 visit now beats a $400 to $800 backflow replacement in April.3
The damage hides all winter.
Nothing looks wrong in December. The crack sits underground until spring start-up, when a zone won't build pressure or a geyser shows up by the driveway. The fix then is digging, parts and labor. The fix now is about half an hour with a compressor.
Most residential blowouts take 30 to 45 minutes.4

Watch the water leave every zone.
Drag the yard around and step through it: summer, first freeze, blowout, winter. That's the half hour you're paying for.
Interactive 3D blowout
Loading the 3D view. If it doesn't appear, the short version: compressed air pushes the water out of every line, valve and head, zone by zone, so there's nothing left to freeze.
Three steps. You don't sit home all day.
No phone tag, no "we'll call you back next week."

Spoke with Chassidy on a Monday and Shane came out the next day to address my sprinkler issue. He was able to take care of the problem in a short time and explained everything in detail.

Same faces every season.
Shane Plummer has spent 26+ years in Colorado irrigation, from neighborhood yards to Castle Pines Golf Club and the Denver Art Museum. The people who blow out your system are the ones who turn it back on in spring.
I have been in the lawn care business for 40 years and have used Sunlight Sprinkler for our customer's sprinkler system's repair, winterization and spring start-up for the last 5 years. They are always reliable and professional.

If anything we blew out freezes, we fix it in spring.
No argument, no service-call fee. If a line, valve or head we winterized cracks from freezing this winter, we repair it at your spring start-up at no cost to you.

Questions people ask before they book
When should I blow out my sprinklers in Denver this year?
Now. Denver Water ended the 2026 lawn-watering season on October 1, so systems are sitting idle with water in the lines, and Denver's average first freeze is October 7. Book before the first hard freeze, not after it.
How much does a sprinkler blowout cost?
$100 for 1 to 4 zones, $110 for 5 to 8, $120 for 9 to 16. Maintenance plan members pay $95 to $115. Systems with 17 or more zones get a custom quote. Additional backflow assemblies are $20 each.
What's included in the blowout?
Water supply shutoff, drain down, a compressed-air blowout of every zone, and recommendations for anything that needs attention before spring.
Do I need to be home?
Tell us in the notes how we get to your shutoff, backflow and controller (gate code, garage, side yard). We'll confirm what we need from you when we text your arrival window.
How long does it take?
Most residential systems take 30 to 45 minutes. Larger systems take longer.
Can't I just do it myself with my compressor?
A small home compressor usually can't move enough air to clear a full zone, so water gets left behind. Too much pressure can crack heads and fittings. Our trucks carry commercial compressors sized for the job.
What if you find something broken?
We tell you and quote it before any work happens. Repairs are $115 per technician hour plus parts ($110 for plan members), and nothing gets done without your OK.
Will Denver let me turn my sprinklers back on next spring?
Denver Water has said sprinklers need to stay off in spring 2027, pending an official resolution. We'll text our customers as soon as the rule is set, so you'll know before you need to book a start-up.
The freeze won't text you first. We will.
Grab your route day now, and you won't think about your sprinklers again until spring.
