Sprinkler System Winterization in Boise

Idaho's harsh winter freezes are devastating to sprinkler systems, with temperatures regularly dropping into single digits and below zero throughout the Treasure Valley. Water left in irrigation pipes, valves, and sprinkler heads expands when frozen, causing catastrophic damage that can cost thousands to repair come spring. Our professional sprinkler winterization service - commonly called a "blowout" - uses commercial-grade, high-volume compressed air equipment to completely evacuate every drop of water from your entire irrigation system before the first hard freeze arrives.

This essential annual service is the single best investment you can make to protect your irrigation system investment, typically preventing $500-3000+ in freeze damage repairs for a service that costs just $75-125. Idaho's freeze-thaw cycles are particularly destructive - daytime temperatures in late fall and early spring can climb above freezing while nights drop well below, creating repeated expansion and contraction that can crack even properly winterized components if any water remains. Our technicians use professional compressors delivering 80-120 CFM (cubic feet per minute) of airflow - far more volume than homeowner equipment can provide - ensuring complete water removal from mainlines, lateral lines, valve boxes, sprinkler heads, and backflow preventers.

We've winterized thousands of systems throughout Kuna, Boise, Meridian, Nampa, Caldwell, and Eagle, and understand the specific challenges Idaho weather presents. Timing is critical: winterize too early (while you still need to water) and your lawn suffers; wait too long and an unexpected hard freeze destroys your system overnight. October is the ideal month in Idaho, after watering season ends but before temperatures plummet.
