While Raleigh winters are relatively mild, the occasional hard freeze can cause costly damage to irrigation systems. Our winterization service thoroughly blows out all water from pipes, valves, and sprinkler heads using industrial-grade air compressors. We document the location of all components for easy spring startup.
The process includes inspecting backflow preventers (required by Raleigh water regulations), checking for leaks that may have developed during the season, and making minor repairs to vulnerable components. For systems with smart controllers, we provide guidance on proper off-season settings.
We schedule winterizations in late October through November, before the first predicted hard freeze. Customers receive a dated tag on their system confirming service completion, along with instructions for what to do if unexpected freezing weather occurs after winterization.

Frequently Asked Questions
When should I winterize in Raleigh?
Late October to mid-November is ideal, before temperatures consistently drop below freezing at night. We monitor forecasts and adjust schedules accordingly.
Can I do this myself with a small compressor?
DIY attempts often leave water in pipes that can freeze. Our 175+ CFM compressors achieve complete evacuation that small units can't match.
Do you offer spring startup services?
Yes, we provide complete startup testing in March-April, checking for winter damage and adjusting heads as needed.
