Plano & North DFW · Same-day & next-day service
Most “sprinkler guys” in DFW aren’t licensed — Texas law requires it for paid repair work. We are. One licensed irrigator who diagnoses the whole system, quotes a flat price before any work begins, and fixes it right: valves, heads, leaks, wiring, backflow, and the systems nobody else documents.
Most calls diagnosed same or next day · You approve the flat price before any work begins
Texas Licensed Irrigator — LI0026061Required by Texas law for sprinkler repair. Ask any company for theirs.
Describe the problem — we'll call back with an arrival window, usually same day.
Start with what’s wrong
You don’t need to know whether it’s a valve or a wire — that’s our job. Find the symptom, and we’ll show you the fix. Every repair is flat-rate and quoted before work begins.
Water running until you kill the main? A stuck valve ignores the controller. Shut the isolation valve at your backflow, then it’s a valve repair.
No water at all on one zone is usually electrical, not mechanical — a solenoid or a broken wire. We meter-test before replacing in wiring & controller repair.
Dead circles, a spray hitting the sidewalk, or water erupting beside a head — the lawn is writing a diagnosis. Most are a same-visit head repair.
A strip that never dries or a water bill that jumped points underground. We find it by instrument, not shovel, in leak detection & repair.
That letter has a deadline. We’re the licensed irrigator who repairs and replaces what the testers flag — backflow repair & replacement, retest coordinated.
Buying a house, after a freeze, or a city notice on the door? One full inspection runs every zone and hands you a priced punch list.
Not sure, or seeing several of these at once? That usually means one underlying cause, not several — a full system inspection runs every zone and hands you a priced punch list. Or just call (469) 970-2715 and describe it.
The licensed difference
Eldorado isn’t a dispatch service routing you to whoever’s free. When you call, you reach Jonathan — a Texas Licensed Irrigator (LI0026061) who has been repairing North Texas systems since 2013, working out of a shop on F Avenue in east Plano, in the middle of the oldest sprinkler systems in Collin County.
That license isn’t a formality. Texas law requires a TCEQ irrigator license for anyone who repairs or alters an irrigation system for pay — and most of the cheapest options on Nextdoor don’t hold one. It’s also what lets us do the work correctly: alter a system properly, sign off on backflow, and keep your setup legal under your city’s watering ordinance. Ask any company you call for their LI number. Ours is on every page of this site.
The company rule customers quote back to us in reviews started here: fix only what’s broken. We’ll tell you when a repair beats a replacement, when a manifold rebuild beats four service calls, and when your old system is worth keeping — which, in this clay, it usually is.

How our pricing works
Most companies make you call to learn a price, then bill by the hour while the surprises in your yard run up your invoice. We do the opposite: a $[XX] service call buys a real licensed diagnosis — every zone tested — and then a flat price you approve before any work begins. The number you approve is the number on the invoice. No hourly meter, no “while we were in there.”
The diagnosis fee is applied to your repair, so when we do the work, it effectively cost nothing. And because flat-rate puts the risk of a stubborn job on us instead of you, it rewards doing the work quickly and correctly — which is the whole point.
Our full rate tables are public — service calls, heads, valves, leaks, wiring, and backflow — with honest ranges and what moves a price up or down.
We also install sod
Most sod failures aren’t grass failures — they’re water failures. We’re the licensed irrigator that also installs turf, which means coverage gets verified before a pallet is ordered and heads get raised to the new grade after. Old turf stripped, Blackland clay prepped, seams rolled, and an establishment plan written for your city’s watering rules.
St. Augustine, Bermuda, and Zoysia sod installation across the same cities we repair — matched to your sun, your shade, and what the 2021 freeze taught us about which grass survives here.
How it works
Tell us what the system’s doing. We give you an honest arrival window — usually same or next day, and emergencies jump the queue.
We run every zone — valves, wiring, pressure, coverage — not just the symptom you called about, then quote a flat price you approve before any work.
We fix it, run the system with you watching, and set the controller to your city’s watering schedule before we leave.
Free DIY guides
We publish the same diagnostic methods we use on paid calls — honestly, with the point where each job stops being DIY. Fix it yourself, or know exactly what you’re paying for when you call.

What our customers say
Called about one zone that wouldn’t come on. He found a corroded splice, fixed it, and didn’t try to sell me a thing I didn’t need. Quoted the price up front and that was the price.
Failed my backflow test with a deadline looming. Eldorado had it replaced and coordinated the retest within two days. Actually licensed, unlike the last person I called.
Water bill doubled and I couldn’t find why. He isolated it to one zone, dug one neat hole, and the lawn was back to normal in a week. Worth every penny.
Common questions
For any paid sprinkler or irrigation repair in Texas, yes — state law requires a TCEQ irrigator or irrigation technician license, and a lot of “sprinkler guys” in DFW don’t hold one. Eldorado is owned and operated by a Texas Licensed Irrigator, LI0026061. On your own home you can legally DIY, which is why we publish our repair methods free.
Everywhere within about 30 minutes of our east Plano shop: Plano, Frisco, McKinney, Allen, Richardson, Dallas, and North Dallas. From most of Collin County and North Dallas we’re a short drive, with same-day and next-day service in peak season.
Flat-rate, always quoted before any work begins. A $[XX] service call covers a full system diagnosis and is applied to your repair. You approve the exact number first, and the invoice matches the quote — no hourly meter, no surprises. Published ranges live on our sprinkler repair cost guide.
Same-day or next-day for most calls, and emergencies — a zone stuck on, an active main-line leak — jump the queue because they’re costing you water by the hour. Repair is phone-first: call (469) 970-2715 and we’ll give you an honest arrival window.
The whole system: valve repair, head repair, leak detection, wiring and controller repair, backflow repair and replacement, inspections, drip and foundation watering, new zones, and full system installation. We also install sod — St. Augustine, Bermuda, and Zoysia — as the licensed irrigator who verifies your sprinklers first.
Repair, usually — and we say that as the company that profits either way. Most North Texas systems have sound buried pipe even at 30–50 years; what fails are components, which is far cheaper to fix than to replace wholesale. We recommend a new system only when the pipe itself is failing in multiple places, and we’ll tell you so plainly.
For repairs, the $[XX] service call buys a real licensed diagnosis — every zone tested — and it’s applied to the work, so an actual repair effectively makes the diagnosis free. For sod and new installations, the on-site measure and design quote are free.
Yes — licensed and insured. The license (LI0026061) makes the work legal and held to a state standard; the insurance protects your property. Ask any company you call for both before they open a valve box.
One licensed irrigator for the whole system — call now, same-day service in peak season goes fast.
