Irrigation repair in Houston usually starts with a symptom: a brown strip in the lawn, a zone that will not shut off, a geyser where a head used to be, or a water bill that jumped for no clear reason. Most sprinkler problems are small and fixable. The trick is finding the actual cause rather than replacing parts until something works.
We troubleshoot existing systems zone by zone, from the controller to the last head, and repair broken heads, leaking valves, bad wiring, and failing controllers. Our irrigation work is TDLR licensed, and we use Hunter replacement parts. If the system is beyond repair or was never laid out properly, we will tell you that directly, and show you what replacement would involve.

Signs Your Sprinkler System Needs Repair
Sprinkler problems tend to show up in the lawn first. Dry patches between heads point to coverage gaps or clogged nozzles. Soggy spots that never dry out usually mean a leak in the line or a valve that will not close. A zone that does not come on at all points to wiring, a solenoid, or the controller.
- Brown or dry areas in the lawn even when the system runs
- Pools of water or soggy ground near heads or valve boxes
- Heads that do not pop up, spray sideways, or are broken off
- A zone that will not turn on or will not turn off
- Low pressure or misting spray across the system
- A water bill much higher than normal for the season

How Irrigation Troubleshooting Works
A sprinkler system has a few main parts: the controller, the wires running to each valve, the valves themselves, the pipes, and the heads. Most problems sit in one of those spots. We start at the controller, testing each zone and checking for error messages or wiring faults, then move outward to the valves and finally to the heads.
Houston conditions cause specific failures. Shifting Expansive clayClay soil that swells when wet and shrinks when dry. Much of the Houston area sits on it, and it affects foundations, paving and drainage design. In practice: Keeping soil moisture around a slab foundation steady, without ponding or bone-dry spells, is part of good drainage design here. can crack PVC fittings. Tree roots can crush lines near mature oaks. Hard freezes, such as the one in 2021, crack backflow devices and exposed pipes. Mowers and edging tools break heads set too high. Knowing these patterns helps us find the fault faster.

Our Irrigation Repair Process
Each service call follows a systematic check, so we fix the cause, not just the symptom.
- Run each zone from the controller and note what works and what does not
- Check controller settings, wiring terminals, and the rain sensor
- Locate valve boxes and test solenoids and diaphragms
- Trace wiring faults with a locator if a zone will not respond
- Walk each zone to find broken, clogged, tilted, or misaimed heads
- Dig and repair leaks in lateral or mainlines
- Replace parts with Hunter components and reset head heights and arcs
- Reprogram the controller for the season and walk you through the changes

Common Repairs and Upgrade Options
Most calls involve a mix of small fixes: replacing broken spray heads and rotors, clearing clogged nozzles, raising sunken heads, repairing cracked pipe, and rebuilding or replacing valves. Wire breaks between the controller and a valve are common in older systems, especially where landscapers have dug through lines.
Repairs are also a chance to upgrade. Swapping standard spray nozzles for Hunter MP Rotators can improve coverage and reduce runoff on clay. Replacing an old controller with a smart controller such as Hunter Hydrawise adds weather-based scheduling. Converting bed zones to drip moves water to roots and away from walls and the foundation.
05
What Affects Irrigation Repair Cost
Repair cost depends on how many problems are found and how hard they are to reach. Replacing a few heads is a quick fix. Locating a wire break or a leak under a walkway takes longer. Valve replacements, controller swaps, and backflow repairs each add parts and labor.
The age and layout of the system matter too. Older systems with buried valve boxes and no map take more time to trace. If repairs approach the cost of a new system, we will explain both options. For a ballpark on larger work, see our ballpark price tool.
06
Repair Shortcuts That Cause Bigger Problems
We often follow behind quick fixes that did not hold: mismatched heads in one zone, which leaves some areas dry and others soaked; valve boxes buried under sod, making the next repair a dig; and wire splices wrapped in tape rather than sealed in waterproof connectors.
We also see heads aimed at the foundation, driveway, or fence, and controllers programmed with a single schedule for the whole year. These cause water waste, uneven lawns, and wet soil against the slab. A proper repair corrects coverage, not just the broken part.
07
When Repair Becomes Replacement, and Related Services
If a system has constant leaks, poor coverage throughout, or zones that mix lawn and beds, a full irrigation system installation may cost less over time. Dead lawn areas from long-term irrigation issues can be restored with sod installation. If soggy areas persist after repairs, the problem may be drainage, which lawn grading and leveling can address.

Irrigation Repair Questions
Why is one sprinkler zone not turning on?
A zone that will not turn on usually has an electrical problem: a broken wire between the controller and the valve, a failed solenoid, or a controller output issue. It can also be a stuck valve or a closed flow control. Testing the controller and solenoid with a meter usually narrows it down quickly before any digging starts.
Why will my sprinkler zone not shut off?
A zone that keeps running usually has a valve problem. Debris in the diaphragm, a torn diaphragm, or a faulty solenoid can keep the valve open. Shut off water to the system at the main or backflow, then have the valve cleaned or rebuilt. If the controller is sending a constant signal, that needs checking too.
How do I know if my irrigation system has a leak?
Signs include soggy spots that stay wet, water bubbling up near heads or valves, low pressure in one zone, and a water bill that jumps without explanation. With all water off inside the house, check your meter. If it moves while the system is off, there may be a leak in the mainline or a valve.
Is it worth repairing an old sprinkler system?
Often, yes. Many older systems only need heads, valves, or a controller replaced. Repair stops making sense when leaks keep recurring, coverage is poor throughout, or zones mix lawn and beds. A thorough inspection shows which situation you are in, so you can compare repair against replacement.
