Sprinkler System Repair Cost: Pricing Common Irrigation Fixes

Sprinkler repair is priced as a service call plus parts and per-repair labor. Most jobs are diagnosis-driven: you are pricing the visit to find the fault, then the fix. The controller, valves, and mainline are the expensive failures; heads and nozzles are quick.

What do common sprinkler repairs cost?

• Service call / diagnostic: $75–$150
• Replace a spray or rotor head: $10–$25 per head plus labor
• Replace a zone valve: $90–$250
• Repair a wiring fault or solenoid: $75–$250
• Mainline or lateral line break repair: $150–$500
• Controller replacement: $150–$400 installed
• Backflow preventer repair or rebuild: $100–$300; replacement $300–$800

How should the service call be structured?

Charge a diagnostic fee that covers the first 30 to 45 minutes and is credited toward the repair if the customer approves it that day. Irrigation faults hide — a "one zone won't come on" call can be a $15 solenoid or a severed wire under a new patio, and you cannot quote it sight unseen.

What raises the price of a line repair?

Depth of the pipe, what is on top of it (sod, mulch, or a driveway), how much has to be excavated to find the break, and whether the break is at a fitting or a long split. Slab or hardscape over the line changes the job entirely.

What should the estimate note about spring startups?

If you are doing a startup and find damage, separate the seasonal service fee from the repair quote. Winter freeze damage to heads, valves, and backflow assemblies is common and should be quoted per item found, not lumped into the startup price.
