We get it—no one wants to spend money on a service that feels “invisible.” Irrigation winterization doesn’t change how your system looks or waters your plants. But come spring, the value becomes crystal clear—especially if you’re trying to avoid an unexpected repair bill.
What Does an Irrigation Winterization Cost in the Seattle Area?
Professional irrigation winterization typically costs:
- $150 for average-size residential systems (Up to 8 zones)
- $200+ for larger or more complex properties
- $200–$350+ for commercial properties or high-end residential systems with extensive landscaping
Prices vary based on:
- Number of zones
- Accessibility of system components
- Whether the system requires multiple blow outs – some systems have multiple points of connection.
- Add-ons like pre-winter inspections or spring startup packages
Like everything in Seattle, the cost are higher than the national average.

DIY vs. Professional: What’s the Real Cost?
