Superior Sprinkler Systems installs and repairs irrigation systems in Sterling, VA, from Sterling Park and Sugarland Run to Countryside, Cascades and Lowes Island. Our shop is in Dulles, a few minutes away. We design new systems, repair aging ones, test backflow preventers for Loudoun Water, and handle spring start-ups and winterizations. Family-owned since 1991.
Sterling has some of the oldest neighborhoods in eastern Loudoun County and some of the newest, often only a few miles apart. Sterling Park and Sugarland Run go back decades, Countryside and Cascades came later, and Lowes Island and Potomac Falls sit along the Potomac with larger lots and more mature landscaping. That range shows up in our work. On one street we are replacing a controller that has hung on the garage wall for twenty years, and on the next we are designing the first system a yard has ever had.
Our shop is on Azalea Lane in Dulles, which puts most of Sterling a short drive away. Superior Sprinkler Systems has worked here since 1991 under the same family, so a service call does not mean waiting on a crew coming in from another county.
A system that has been in the ground for twenty or thirty years tends to fail in the same places. Heads stop popping up or stop rotating, valves weep or stick open, wire splices corrode, and controllers lose their programs after a power outage. In most cases the pipe is still sound and the system is worth fixing. We test every zone, check pressure at the tap, and tell you plainly whether repair or replacement makes more sense.
When the yard has changed since the system went in, with trees grown over spray heads or beds added where lawn used to be, we adjust the zones to match what is there now. On a retrofit we can often reuse the existing pipe and simply add valves and controller stations instead of starting over.
Plenty of Sterling homes have never had irrigation. Putting a system into a finished yard means working around mature trees, fences, driveways and planting you want left alone. We locate utilities first, flag every head position and trench line so you can see the layout before anything is cut, and route pipe to protect roots. Beds and foundation plantings go on drip, which puts water at the roots and keeps it off siding and windows.
Loudoun Water requires an approved backflow assembly on every irrigation system it serves, and that assembly has to be tested and the results filed each year. Our DPOR certified backflow testers handle the test and the paperwork for you. If a device fails, we explain why and quote the repair before any work is done. Our backflow testing and certification page covers the requirements in more detail.
We work throughout Sterling, including Sterling Park, Sugarland Run, Countryside, Cascades, Lowes Island and Potomac Falls, along with the homes off Route 7 and Route 28. Several of these communities have an HOA with architectural guidelines. If yours needs to review an irrigation project, we can provide a drawn layout and equipment list to go with your application.
The connection. We tie into the house supply inside or outside depending on the plumbing, with a master shut off valve fitted somewhere reachable so a burst line can be isolated in seconds.
Backflow prevention. Loudoun Water requires an approved assembly on every irrigation system it serves. We install it where it is easy to reach for the yearly test.
Controller. Garage wall as standard. Basement, shed or an outdoor rated enclosure if you prefer. WiFi controllers let you run a zone from your phone, and weather based scheduling keeps the system from watering into a thunderstorm. A rain shut off gives similar protection at a lower cost.
Parts. Rain Bird, Irritrol and Hunter equipment, WaterSense certified. Rigid PVC in the ground rather than flexible tubing. Rotors for open turf, matched precision sprays for the tight areas, and drip through beds.
Design. Drawn by a licensed irrigator after utilities are located, with head to head coverage guaranteed and any dry spot corrected under the warranty.
Warranty. Three years against defects, with first year winterization, spring start up and backflow test included.
Site visit and quote. We check pressure and flow at the tap, measure the lot, look at grade, sun and planting, and ask what matters to you. You get a written, itemized estimate inside 24 hours.
Permits and marking. We pull the permits and arrange utility locating. Head positions and trench lines get flagged so you can see the layout before anything is cut.
Install day. Trenching, pipe, valves, heads, wiring and controller. On a typical Sterling lot this is one day, occasionally two.
Start up and handover. Zone by zone testing, arc and nozzle setting, run times programmed for the season, backflow test filed, warranty activated, and a walkthrough so you know what every button does.
Superior Sprinkler Systems is a family-owned irrigation company. Chris is our owner and founder, Brian is our general manager, and Dylan leads irrigation design and installation. Our own crews do the work, every layout is drawn by a licensed irrigator, our backflow testers are DPOR certified, and we carry full insurance. You can read more about our team or see what our customers say.
Along with Sterling, we install and service irrigation systems in nearby Ashburn, South Riding, Brambleton and Leesburg, and across Loudoun County. We also serve nearby Herndon and Lansdowne.
We guarantee against defects for three years. In year one, winterization, spring start-up and your backflow test are part of the package.
We mark buried utilities before anything is cut. Your layout is drawn by a licensed irrigator and sized to the lot, which on a compact Sterling yard means arcs set to stop at the turf edge rather than on the siding. Guaranteed head-to-head coverage, with dry spots corrected under warranty.
Weather-based scheduling, moisture sensors and zone control, with WiFi controllers you can run from your phone. The system skips a cycle when rain has already done the job, which is where the real saving sits and what Loudoun Water asks of its customers.
Installed by experienced crews with attention to detail, giving efficient water distribution and the least possible disruption to your Sterling property, new build or established.
Tied into your supply inside or outside the home, with an accessible master shut-off valve so a burst line can be isolated in seconds.
Required on every irrigation system in the Loudoun Water service area. We install an approved assembly, test it at commissioning and file your report every year after that.
Standard placement is the garage wall, which fits most Sterling floor plans. Basements, sheds and outdoor-rated cabinets are available instead.
Rain Bird, Irritrol and Hunter equipment. Rigid PVC pipe, not flexible tubing. Rotors on open turf, matched precision nozzles on the tight areas near walks and siding, and drip through beds.
We keep servicing the system, adjusting it as your planting fills in and repairing it if something breaks.
We check pressure and flow at the tap, measure the lot and look at grade, sun and planting. You have a written estimate within 24 hours.
We handle the permits and utility locating, flag the head positions for you to see, then trench, pipe, wire and test. One day on a typical Sterling lot, occasionally two.
Each zone tested, arcs and nozzles adjusted, run times set for the season and for new sod where that applies, backflow filed, warranty activated, and a walkthrough so you know what every button does.

Professional& ExperiencedQ: My sprinkler system is over twenty years old. Should I repair it or replace it?
A:It depends on the condition of the pipe and how much the yard has changed. If the pipe is sound, replacing worn heads, valves and the controller usually brings the system back for far less than a new install. If the layout no longer fits the trees and beds, or the system leaks in several places, a redesign makes more sense. We test every zone and give you both options in writing.
Q: Can you install irrigation in a yard with mature trees?
A:Yes. We locate utilities, flag the layout before digging, and route pipe to protect roots. Drip works well in beds and around trees, and spray zones can be set to keep water off trunks, siding and walkways.
Q: Who handles the backflow test in Sterling?
A:Sterling homes are served by Loudoun Water, which requires the backflow assembly on an irrigation system to be tested and the results filed every year. Our DPOR certified testers do the test and file the report for you.
Q: How long does a sprinkler installation take?
A:On a typical Sterling lot, installation takes one day, occasionally two. You get a written estimate within 24 hours of the site visit, and we pull permits and arrange utility marking before install day.
Q: Can I control my sprinkler system from my phone?
A:Yes. We install WiFi controllers that let you run zones, change schedules and shut the system off from your phone. Weather based scheduling adjusts watering to the forecast, and a rain shut off gives similar protection at a lower cost.
Q: Do you winterize sprinkler systems in Sterling?
A:Yes. Before the first freeze we shut off the water supply and blow out every zone with compressed air to clear the pipes, valves and heads. In spring we turn the system back on, test each zone and repair anything that broke over the winter.
