Soggy spots, dry patches, a zone that won't turn on or a spike in your water bill usually mean something in the irrigation system has failed. Most problems come down to a few parts: heads, valves, pipes, wiring and the controller.
This guide lists typical repair prices by component, what drives the bill, and when replacement makes more sense. For a new system or a full replacement, see our sprinkler system installation cost guide.
Average cost
Typical sprinkler repair prices, parts and labor included, national averages as of October 2026:

Sprinkler repair cost by component
Installed repair or replacement prices reported by Angi, HomeGuide and LawnStarter:
| Component | Typical repair cost | Part only |
|---|---|---|
| Sprinkler head | $60–$110 | $3–$30 |
| Zone valve | $70–$300 | $14–$150 |
| Broken pipe / leak | $120–$400 | $0.45–$5 per linear foot |

Cost breakdown: materials, labor, permits and extras
Line-item estimate for diagnosing and replacing a faulty zone valve and two broken heads on an in-ground system. Ranges are national, as of October 8, 2026.
| Cost item | Typical range | What it covers |
|---|---|---|
| Parts | $30–$120 | Valve ($14–$150) and two heads ($3–$30 each) |
| Labor | $75–$200 | 1–2 hours at $50–$100 per hour |
| Service call / diagnosis | $0–$100 | Minimum charges run $50–$150; often credited toward the repair |
| Contingency (about 10%) | $15–$40 | Extra fittings or a damaged lateral line |
| Estimated total | $120–$460 | Before any discounts or rebates |
Labor and the service minimum usually cost more than the parts, so fixing several problems in one visit saves money.
What affects the price
- Components. What broke matters most. A head replacement runs about $60–$110, a valve $70–$300, and a backflow preventer $450–$1,700.
- Leaks. A broken pipe or leaking lateral costs about $120–$400 to fix. Main-line leaks, deep pipes and repairs under pavers or roots cost more because of digging.
- Valves. Zone valves stick, leak or fail electrically. Replacement typically costs $70–$300 and takes 1–2 hours; a valve manifold repair runs $75–$200.
- Controller. A dead or glitchy controller usually costs $100–$500 to repair or replace, depending on whether you choose a basic timer or a Wi-Fi smart model.
- Diagnosis. Finding the problem takes time. Contractors charge about $50–$100 per hour with a $50–$150 minimum, and emergency or after-hours calls can run $150–$300 per hour.
Ways to save
- Bundle repairs with a spring start-up or fall winterization visit so you pay the service minimum once; annual plans run about $140–$400.
- Replace simple parts such as nozzles and heads yourself; heads cost $3–$30 and screw on without special tools.
- Winterize every fall in freezing climates (about $50–$150) to avoid cracked pipes, valves and backflow devices.
- Mark heads before aeration, edging or landscaping work so crews don't break them.
- Get at least two or three quotes for big-ticket repairs such as backflow replacement, and ask whether a full system upgrade is better value on an old system.
How to get an accurate quote
For larger repairs, get at least three written quotes from licensed irrigation contractors. Give each the same information:
- The symptoms: which zones are affected, wet or dry spots, water running when the system is off, or controller error messages.
- The age of the system, the controller brand and model, and the number of zones.
- Where the backflow device, valve boxes and shutoff are, if you know.
- Ask for the hourly rate, minimum charge, parts markup and any warranty on the repair.
FAQ
How much does it cost to replace a sprinkler head?
Replacing a sprinkler head usually costs $60–$110 with labor, and about $85 on average. The head itself costs only $3–$30, so many homeowners do this repair themselves.
Should I repair or replace my sprinkler system?
Repair is usually cheaper when the problem is limited to a few heads, a valve or one leak. If the system is old, needs repeated repairs or lacks a working backflow device, compare repair quotes with a replacement at about $1,640–$3,580.
How much does a backflow preventer test cost?
Many water utilities require periodic testing by a certified tester. The cost varies by area; LawnStarter's backflow replacement range of $280–$1,550 includes labor and testing.
