Our Irrigation & Sprinkler Services

Controller & Wiring Repair

We repair faulty controllers, bad wiring, short circuits, and programming issues so your system runs on schedule and uses water efficiently.

System Optimization

We adjust heads, improve coverage, correct pressure issues, and fine‑tune your system to reduce water waste and improve lawn health.

Spring Startups

We safely turn your system back on for the season, check for winter damage, and make sure everything is running properly before the heat hits.

Winterization

We blow out your system to prevent freeze damage and protect your pipes, valves, and backflow during Colorado winters

Backflow / Vacuum Breaker Replacement

We replace damaged or leaking backflow preventers and vacuum breakers to keep your irrigation system safe and compliant with Colorado plumbing codes. Whether it’s a cracked PVB, a leaking bonnet, or freeze damage, we install a properly sized new assembly and ensure everything is sealed, tested, and functioning correctly.

We diagnose issues fast and provide reliable, long‑lasting repairs for residential sprinkler systems across Denver and Boulder. Whether it’s a single broken head or a full system problem, we make sure your lawn gets the water it needs without waste.

Sprinkler Repair

We fix broken heads, leaks, clogged nozzles, low pressure, overspray, and uneven coverage. If something isn’t working the way it should, we’ll find the problem and repair it correctly.

Zone & Valve Troubleshooting

If a zone won’t turn on, won’t shut off, or is stuck running, we diagnose wiring, solenoid, and valve issues to get your system back under control.

Leak Detection & Pipe Repair

We locate and repair underground leaks, broken lines, and fittings that waste water and damage your yard.

Valve Replacement (Shutoff & Stop‑and‑Waste Valves)

We replace worn, leaking, or seized shutoff valves and stop‑and‑waste valves to restore proper control and drainage for your sprinkler system. If your valve is stuck, leaking underground, or no longer shutting off water to the irrigation line, we locate it, dig it up cleanly, and install a durable, code‑compliant replacement to protect your system from water loss and freeze damage.
