We Fix Sprinkler Systems Other Companies Walk Away From
A sprinkler system that isn't working right wastes water, drowns some parts of your lawn, and leaves brown patches in others. JNP Irrigation Services repairs lawn sprinkler systems of every brand and age across Milwaukee and Southeast Wisconsin — including systems installed by other companies. When you call, you talk directly to Juan, and Juan is who shows up.
Common Sprinkler Problems We Repair
- Broken or clogged sprinkler heads — heads snapped by mowers, stuck risers, and nozzles clogged with debris are replaced and adjusted for full coverage.
- Zones that won't turn on (or won't shut off) — usually a failed valve, solenoid, or wiring issue. We track it down and fix it.
- Leaks and soggy spots — cracked lateral lines and leaking valves waste water and can damage your lawn and foundation. We locate and repair underground leaks.
- Controller and timer problems — blank displays, wrong run times, zones skipping. We repair or replace controllers of any brand.
- Low water pressure — often a partially closed valve, a leak, or too many heads on one zone. We diagnose the real cause instead of guessing.
- Coverage gaps and overspray — we re-aim, raise, or relocate heads so your lawn gets even water and your driveway stays dry.
Smart Upgrades While We're There
If your system is more than a few years old, small upgrades can make a big difference. We install smart Wi‑Fi controllers that adjust watering to the weather, rain sensors that skip watering after a storm, and high‑efficiency nozzles that cut water use. Upgrades pay for themselves quickly on a Wisconsin water bill.
