Sprinkler System Repair in Flower Mound and Denton County: Heads, Valves, Leaks and Controllers
Most repair visits run $120 to $350 including parts
A sprinkler system in Denton County takes a beating. North Texas summers push systems hard: triple-digit heat, Blackland clay on the east side of Denton County that shrinks and shifts fittings underground, sandy Cross Timbers soil that drains fast, hard water that scales nozzles, and winter freezes that average from late November to mid March and split backflow preventers that were not covered. The result is the same set of problems every spring and summer: heads that spray the sidewalk instead of the lawn, a zone that runs for an hour and never shuts off, brown half-circles where a rotor stopped turning, and a water bill that jumped for no visible reason.
What we repair
- Broken, sunken or misting spray heads on every brand, including Rain Bird, Hunter, Toro and Orbit. Heads are matched for arc and radius so you do not end up with one zone over-watering and the next one dry.
- Rotors that stopped rotating or lost their adjustment after a mower hit them.
- Zones that will not turn on. Usually a stuck solenoid, a cut wire, or a controller fault. The tech traces it to the real cause instead of guessing.
- Zones that will not turn off. Debris in a valve diaphragm or a failed solenoid. This one floods lawns and drives up water bills, so it gets priority scheduling.
- Lateral and main line leaks that show up as soggy spots, sinkholes near the curb, or water running down the gutter when the system is off.
- Low pressure across a zone, which is often a cracked fitting underground rather than a city supply problem.
- Coverage fixes: adding or moving heads where new landscaping, a fence, or a patio changed the layout.
How a repair visit works in Flower Mound
- You describe the symptom when you call. If a zone is stuck on, we walk you through shutting the system down at the backflow or the controller so you stop losing water tonight.
- The technician runs every zone, not just the one you called about, and gives you a written list of what is broken and what it costs to fix. Nothing is replaced without your approval.
- Most repairs are finished the same visit. Parts for common heads, nozzles, valves and wiring are on the truck.
- Before leaving, the tech sets the controller schedule to match the city watering schedule: twice a week by street address in Flower Mound, Lewisville, Denton and most Denton County cities, never between 10am and 6pm (year-round in Flower Mound, summers elsewhere).
Pricing
$120 to $350 covers the large majority of calls in Flower Mound, including the diagnostic and the parts. Larger jobs such as a mainline break under a driveway or a full valve manifold rebuild are priced before any digging starts.
Doing it yourself
Swapping a pop-up head is a fair weekend job. Chasing an electrical fault across six zones, finding a lateral leak under sod, or rebuilding a valve box is not, and a mistake on the mainline side of the backflow can send water back toward the house. That side of the assembly is licensed work in Texas, and the license number is on the invoice.
Say which zone and what it is doing when you call (469) 949-2629. A tech is in Flower Mound and the rest of Denton County every week.
