Quick math: a standard 6-zone system lands at $100 to $130 in Angi’s zone table – and that sits comfortably inside both HomeGuide’s $50 to $150 flat range (which covers up to 12 zones) and LawnStarter’s $59 to $144 national band. For most suburban systems, budget around $90 to $130.

Where they agree (and why the ranges look identical): all three references cluster around $50 to $150, and LawnLove publishes a near-identical $60 to $145 band to LawnStarter’s $59 to $144 – the two share city-level pricing data, so treat them as one estimate, not two. Angi’s $93 average across 8,225 projects is the most data-backed single number. The real spread comes from zone count and method, not from which source you trust.1,2,3
What pushes the price up
Zone count: the primary factor – base quotes typically cover 6 to 12 zones, then each extra zone adds $5 to $20 depending on the pro.1,2
Winterization method: a manual drain runs $75 to $150, automatic drain valves $90 to $175, and a full compressed-air blowout – the most thorough option – $100 to $250 per Angi.1
Extra repairs: if the pro finds cracked heads or leaky valves mid-blowout, irrigation labor runs $50 to $100 per hour per HomeGuide.2
Timing: book before the first hard freeze – a burst backflow preventer or cracked line costs far more than the $50 to $150 blowout. See our sprinkler system cost guide for repair and installation context.
Three worked examples (we did the math)
| Project | Cost basis | Total |
|---|---|---|
| Standard 6-zone system, blowout | published bands (Angi vs HomeGuide vs LawnStarter) | $100 – $130 vs $50 – $150 vs $59 – $144 |
| 14-zone large system | $50 – $150 base (12 zones) + 2 x $5 – $10 extra (HomeGuide) – our math | $60 – $170 |
| Winterize now + spring startup | $50 – $150 + $60 – $125 (HomeGuide) – our math | $110 – $275 (yearly plan: $140 – $400) |
These are example projects, not quotes – zone count, method and region set the real number. Installing or expanding a system? See sprinkler system cost.

FAQ
How much does a sprinkler blowout cost? $56 to $137 typical per Angi ($93 average across 8,225 projects); HomeGuide puts winterization at $50 to $150 for up to 12 zones and LawnStarter at $59 to $144.1,2,3
Is a blowout better than draining? A compressed-air blowout ($100 to $250 per Angi) clears the most water and is the safest bet in hard-freeze climates; manual ($75 to $150) and automatic ($90 to $175) drain valves work in milder regions.1
Can I skip winterizing my sprinklers? Only in freeze-free climates. Anywhere lines can freeze, trapped water expands and cracks pipes, valves and backflow preventers – repairs that dwarf the $50 to $150 blowout.2
Is a yearly maintenance plan worth it? HomeGuide prices winterize + tune-up + spring startup plans at $140 to $400. Booked separately, winterize plus startup alone runs $110 to $275 – our math – so a plan mainly pays off if you would use the tune-up visit.2
