Sprinkler Winterization in Charlotte, NC
Compressed-air blowouts that protect your system from Charlotte's first hard freeze.
Service Overview
Irrigation Winterization tailored to your property
Charlotte winters are mild, but they're not mild enough to skip winterization. A single hard freeze in December or January is enough to crack a backflow preventer, split a PVC fitting, or burst a poly lateral — and you don't find out until spring start-up when water is shooting out of the ground in three places at once. The repair bill from one cracked backflow assembly is often higher than five years of winterization service combined.
We winterize residential and commercial irrigation systems across Charlotte, Huntersville, Cornelius, Davidson, Mooresville, Ballantyne, Fort Mill, Tega Cay, and the surrounding metro. A proper blowout uses a high-CFM commercial air compressor (not a pancake compressor) to push every drop of water out of every zone, plus we shut down the controller, drain and protect the backflow preventer, and insulate exposed components.

Who it's for
Every irrigation system owner in the Charlotte metro
If you have a sprinkler system, you need it winterized. There are no exceptions — even systems with auto-drains can hold water in low spots and crack.
Homeowners who skipped it last year
If you got lucky last winter, don't push it. The cost of one cracked backflow preventer ($400–$900 plus labor) easily exceeds 5+ years of winterization service.
Property managers & HOAs
Multi-property winterization scheduled together with single-point billing. We document each property and provide spring start-up service in March/April.
How we scope your project
Every property is different, so every quote is too. Here's the general path we take from first call to finished work — adjusted to fit the size, complexity, and goals of your specific project.
1. Schedule before first freeze
We winterize from early November through the first week of December — before the typical first hard freeze in the Charlotte metro.
2. Compressed-air blowout
We connect a commercial high-CFM air compressor and blow out each zone individually until no water comes through the heads — not just a quick pass.
3. Backflow & controller shutdown
We close supply, drain the backflow assembly, and either insulate or remove and store it. Controller is set to rain/off mode.
4. Spring start-up service
Optional spring start-up: we re-pressurize, walk every zone, replace any winter-damaged heads, and reprogram the controller for the season.

Frequently asked questions
When should I winterize my system in Charlotte?+
Schedule between mid-November and early December — before the first hard freeze (typically late December but can come earlier in cold snaps). We start booking in October.
How much does winterization cost?+
Most residential blowouts run $85–$140 depending on zone count. Annual maintenance packages bundling winterization and spring start-up offer better pricing.
Can't I just do it myself with a shop compressor?+
Most home compressors don't push enough CFM to clear lines properly — they push pressure, not volume. Inadequate blowouts often leave water in low spots that still freeze and crack pipes. The repair cost dwarfs the service cost.
What about my backflow preventer?+
The backflow assembly is the #1 freeze casualty. We drain it, and on exposed installations we insulate it with foam covers or remove and store the testable assembly until spring.
Don't gamble on a mild winter.
Schedule your fall blowout — and we'll handle spring start-up too. Annual maintenance packages save vs paying à la carte.
