Commercial repair services
Six systems, one licensed diagnosis
Every visit starts with a zone-by-zone diagnosis — because the head you can see leaking is rarely the only thing wrong with a 30-year-old system.
Sprinkler valve repair & replacement
Stuck or dead common-area zones, weeping valves, full manifold rebuilds on aging association systems.
Sprinkler head repair & replacement
Vehicle-struck rotors, hardscape-edge heads, nozzle matching across large zones — visible turf, fixed.
Sprinkler leak detection & repair
Main-line and lateral leak location across large properties — isolated by instrument, excavated in one neat square.
Sprinkler wiring & controller repair
Long-run wire faults, multi-controller properties, dead stations, sensor mandates, smart upgrades.
Backflow repair & replacement
Failed your commercial annual backflow test? We repair and replace double check assemblies on deadline.
Sprinkler system inspections
Recurring commercial walkthroughs — every zone run, ordinance compliance verified, photo punch list delivered.
We service every major brand — Rain Bird, Hunter, Toro, Irritrol, Weathermatic, Orbit — plus smart controllers like Rachio and Hunter Hydrawise, and we can match or retrofit parts on systems whose installers disappeared decades ago.
Diagnosis guide
Why is your sprinkler system not working?
Nearly every commercial irrigation call starts with one of these six. Here's what each usually means on a North Texas property.
One zone won't turn on
Usually a failed solenoid, a broken field wire, or a controller station gone bad — common on properties where years of landscaping crews have nicked buried wiring. Diagnosed with a multimeter, fixed with sprinkler wiring & controller repair.
A zone won't shut off
Almost always a worn diaphragm or debris inside the valve holding it open. On aging association systems the whole manifold is often at end of life. This is classic sprinkler valve repair territory.
Heads misting or low pressure
Misting means pressure is too high or nozzles are worn; weak coverage across a whole zone points to an underground leak or a partially closed valve. Starts with sprinkler leak detection.
Water bill suddenly spiked
The classic sign of a main-line or lateral leak you can't see — and on a commercial meter, the monthly number gets big fast. We pressure-test zone by zone to find it.
Brown spots in a green lawn
Dry patches with healthy turf around them mean broken, sunken, or blocked heads — or head spacing that never matched the lawn. Fixed with sprinkler head repair & adjustment.
Controller dead or "no AC" error
Could be the transformer, the panel, or a lightning surge — North Texas storms take out controllers every spring. We repair, reprogram, or upgrade to a smart controller set for your city's watering ordinance.
Flat-rate pricing
Flat-rate commercial repair pricing
Every repair is a flat, documented rate approved before work begins — never hourly, never a running meter while someone digs. The diagnostic visit covers a full zone-by-zone inspection with photos and applies to your repair, so diagnosis is effectively free when we do the work.
| Repair | Flat rate | What it covers |
|---|---|---|
| Service call & diagnosis | $[XX] | Every zone run and tested — valves, wiring, pressure, coverage, controller. Applied to your repair. |
| Sprinkler head replacement | from $[XX] | Matched head and nozzle, set to grade, coverage adjusted. |
| Valve repair / replacement | $[XXX]–$[XXX] | Diaphragm rebuilds to full valve replacement, located and wired. |
| Wiring & controller repair | flat, after diagnosis | Broken wires, solenoids, controller swaps — priced as a fixed number, not hours. |
| Commercial backflow (double check) replacement | quoted by size | Failed-test repairs and replacements on deadline, retest coordinated with your certified tester. |
Your flat rate depends on depth, access, and parts — but once quoted, it does not move. You approve the number before a shovel touches dirt. Full breakdown with examples on our sprinkler repair cost guide.
Local knowledge
Who we keep green — HOAs and commercial sites
Commercial irrigation fails like residential irrigation, at ten times the scale and with a citation letter attached. Here's the work, by property type.
HOAs & multifamily — common areas, monuments, amenity centers
Association systems are usually the oldest infrastructure the HOA owns and the least documented: zones added by three different landscapers, valve boxes lost under fifteen years of mulch, and controllers nobody on the current board has touched. We repair what's broken — stuck common-area valves, dead monument zones, main-line leaks bleeding into the water budget — and we map and label as we go, so the system stops being institutional memory.
Boards get documentation built for board packets: flat quotes before approval, photos of every completed repair, and a zone map that survives the next management transition.
Retail, office & campus — storefronts, churches, schools
On customer-facing property, irrigation failures are visible twice: the brown stripe by the entrance and the spray soaking the sidewalk at 2 p.m. Several of our cities treat the second one as a violation — Dallas requires misdirected heads to be repaired, and Frisco fines commercial properties starting at $200 with escalation to irrigation-meter lockout. Head and rotor repair on the hardscape edges is the cheapest compliance and curb appeal money on the property.
Long wire runs and multi-controller layouts make electrical faults the signature commercial failure — and the reason we diagnose with instruments before anything is replaced: wiring and controller repair, documented zone by zone.
Ordinances & compliance
What North DFW cities require of commercial systems
Every city in our territory schedules watering — and several go further, regulating the condition of the system itself. For commercial property, that turns deferred irrigation maintenance into a compliance line item.
City exposure — the rules with teeth
| City | Commercial exposure |
|---|---|
| Frisco | Unrepaired leaks & broken heads are violations; fines from $200, meter lockout possible |
| Dallas | Broken, missing, or misdirected heads must be repaired; rain & freeze sensors required |
| Richardson | Operating a poorly maintained system is prohibited outright |
| McKinney | Rain/freeze sensor required on every system, regardless of age |
Plano and Allen add assigned-day schedules (HOA systems in Plano follow the even-address schedule), and every city requires annual testing of commercial backflow assemblies. We keep the current rules for all seven cities on our city pages, starting with sprinkler repair in Plano.
Where repair meets compliance
A failed annual backflow test is the deadline that drives most commercial calls: the certified tester flags the double check assembly, the city sets the clock, and the property needs a licensed irrigator who can repair or replace the assembly and coordinate the retest before the file closes — or the meter does. That sequence, fast, is our specialty.
The cheaper path is never needing the letter: a recurring commercial sprinkler check runs every zone, verifies sensors and schedules against the current ordinance, and delivers a photo punch list — the difference between a $[XX] head swap in March and a cited brown common area in July.
Your specialist
Meet Jonathan, your irrigation specialist
Eldorado isn't a national maintenance vendor routing tickets — when your property calls, you're talking to the licensed irrigator who shows up. Jonathan has been repairing North Texas irrigation since 2013, holds Texas irrigator license LI0026061, and works out of a shop in east Plano, within 30 minutes of every property we serve.
His rule on every job is the one customers keep repeating in reviews: fix only what's broken. You get a zone-by-zone diagnosis, a flat price before work starts, and an honest answer when something doesn't need replacing.

Questions
Commercial irrigation repair, asked & answered
How much does commercial irrigation repair cost?
Commercial repairs are flat-rate, exactly like our residential work: the diagnostic visit is $[XX], applied to the repair, and you receive a documented quote — with photos of what we found — before any work is approved. Typical line items: rotor or head replacement from $[XX], valve replacement $[XXX]–$[XXX], commercial double check assembly replacement quoted by size after inspection. Larger scopes get a written proposal per property.
Does commercial sprinkler repair in Texas require a licensed irrigator?
Yes — the same TCEQ rule that covers homes covers commercial property: anyone who installs, alters, repairs, or services an irrigation system for compensation must hold an irrigator or irrigation technician license. Eldorado is owned and operated by a Texas Licensed Irrigator, LI0026061, and that number belongs on any vendor file you keep.
Do you service HOA common-area irrigation?
Yes — common-area systems are a core part of our commercial work: entry monuments, greenbelts, medians, amenity centers, and pool surrounds. We map and document the zones as we repair, so the association isn't dependent on whichever landscaper installed it fifteen years ago, and board-ready photo reports come standard.
Our property failed its annual backflow test — how fast can you replace the assembly?
Usually within a day or two of approval. Cities across North DFW require annual testing of commercial backflow assemblies, and a failed double check is a deadline with teeth — some cities can lock out a non-compliant irrigation meter. We repair and replace the assemblies; we're not a testing company, and we coordinate the required retest with your certified tester so compliance closes in one cycle. Details on our backflow repair & replacement page.
Do you work with property management companies?
Yes. You get one licensed point of contact, documented flat quotes before approval, photos of every completed repair, and invoices written so they survive an owner's audit. We're comfortable being the irrigation line on a vendor list that has to perform across multiple properties.
Can you repair systems with smart or central controllers?
We service conventional controllers and mainstream smart platforms — Rachio, Hunter Hydrawise, Rain Bird — including multi-controller properties. Large central-control and two-wire decoder systems get an honest on-site assessment first: we'll tell you plainly what we can repair and where a manufacturer specialist is the right call.
Do you offer recurring sprinkler checks for commercial properties?
Yes — scheduled walkthroughs are the cheapest line in an irrigation budget: every zone run, heads and nozzles checked, controllers verified against the current watering ordinance, and a punch list with photos before small failures become brown common areas and citation letters. See sprinkler system inspections.
Can you work outside business hours?
Often, yes — early starts and off-peak windows keep spray off customers and tenants. One useful detail in the City of Dallas: licensed irrigation professionals are exempt from watering restrictions while working on-site, so full-system diagnosis can legally run any day, any hour.
The city cited our property for irrigation violations — can you fix it?
That's a normal call for us. Frisco enforces year-round against unrepaired leaks, broken heads, and spray hitting pavement — with commercial fines starting at $200 and escalating to meter lockout. Dallas requires broken, missing, or misdirected heads to be repaired. Richardson prohibits operating a poorly maintained system outright. We repair the cited conditions, set the controller to the current ordinance, and hand you the photo documentation that closes the file.
How do you quote commercial repairs?
Diagnosis first, always: every zone run and tested. You then get a flat, documented quote — itemized, with photos — and nothing proceeds until it's approved. The number doesn't move after approval, and the diagnostic fee is applied to the work.
Why is one zone of our property not running?
Same physics as a home system, bigger consequences: a failed solenoid, a cut field wire, or a controller station — and on large properties, wire runs are long and splice boxes are many, which is why we diagnose with a multimeter and a wire tracker before anything gets replaced. See sprinkler wiring & controller repair.
A zone won’t shut off and it’s flooding the parking lot — what now?
Kill the water at the isolation valve on that system's backflow assembly — that's the fastest stop — then call us. Runoff into a street or parking lot is itself a violation in several of our cities, so a stuck commercial valve is both a water bill and a citation risk. We treat these as priority calls. See sprinkler valve repair & replacement.
Do you install new zones or only repair?
Repair is the core of the business, but yes — we add and extend zones where landscapes have changed, and we install drip conversions for beds and foundation lines, which several cities exempt from watering-day limits entirely. See new zone installation.
What areas do you cover for commercial work?
The same territory as our residential service — everything within about 30 minutes of our east Plano shop: Plano, Frisco, McKinney, Allen, Richardson, Dallas, and North Dallas.
