Superior Sprinkler Systems installs and repairs irrigation systems in Herndon, VA, from the older streets near downtown to Franklin Farm, Floris and McNair. Our Dulles shop is about fifteen minutes away. We design new systems, repair aging ones, handle backflow testing and filing, and provide spring start-ups and winterizations. Family-owned since 1991.
A Herndon address can mean two different places. The Town of Herndon has its own local government, historic downtown and long-established neighborhoods along the W&OD Trail. Much of the area with a Herndon mailing address, including Franklin Farm, Floris and McNair, is actually in unincorporated Fairfax County. The difference matters for permits and paperwork, and we handle both every season.
Our shop is on Azalea Lane in Dulles, about fifteen minutes from most of Herndon. Superior Sprinkler Systems has served this side of Fairfax County since 1991, family owned the whole way.
Many Herndon homes, both in town and in neighborhoods like Franklin Farm, were built in the 1970s through the 1990s, and their sprinkler systems have been through decades of freeze-thaw cycles. We regularly replace heads that no longer rise or rotate, valves that weep, corroded wire splices and outdated controllers. Mature trees are another common issue: shade that did not exist when the system went in changes how much water each area needs.
We test every zone, check pressure at the tap and re-zone or re-nozzle areas that have changed from sun to shade. When the pipe is sound, a retrofit is usually the most cost-effective path. When it is not, we explain the options in writing.
Adding a system to a mature yard means protecting tree roots, walkways, fences and planting beds. We locate utilities first, flag every head and trench line before anything is cut, and put beds and foundation plantings on drip. On the smaller lots near downtown Herndon, we use adjustable-arc nozzles so water stays on the lawn and off sidewalks and neighboring property.
Inside town limits, the Town of Herndon handles its own building permits, so permits and inspections for a new system go through the town. Homes with a Herndon address outside town limits fall under Fairfax County, which runs a cross connection program requiring an annual backflow test by a certified tester with the report submitted to the county. We confirm which rules apply to your address, pull the right permits, and our DPOR certified testers handle the annual test and filing. See our backflow testing and certification page for more.
We work throughout Herndon, including the neighborhoods around downtown and the W&OD Trail, Franklin Farm, Floris, McNair, Fox Mill and the communities off Centreville Road and West Ox Road. We also serve nearby Reston and Oak Hill. Several of these communities have an HOA, and we can provide a drawn layout and equipment list for architectural review when it is needed.
The connection. We tie into the house supply where the plumbing allows and fit a master shut off valve in a reachable spot, so a broken line can be isolated in seconds.
Backflow prevention. An approved assembly is required on in-ground irrigation. We install it where it is easy to reach for the annual test and easy to drain for winter.
Controller. Garage wall as standard, with outdoor enclosures available. WiFi controllers and rain sensors keep the system from running when the lawn does not need it.
Parts. Rain Bird, Irritrol and Hunter equipment, WaterSense certified, with rigid PVC in the ground, rotors for open turf, matched-precision sprays for tight areas, and drip through beds.
Design. Drawn by a licensed irrigator after utilities are located, with head-to-head coverage and any dry spot corrected under 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, measure the yard, note sun, shade and slopes, and talk through what matters to you. You get a written, itemized estimate within 24 hours.
Permits and marking. We pull permits through the Town of Herndon or Fairfax County, depending on your address, and arrange utility locating. Head positions and trench lines are flagged before anything is cut.
Install day. Trenching, pipe, valves, heads, wiring and controller. Most Herndon lots take one day, occasionally two.
Start-up and handover. Zone-by-zone testing, arc and nozzle adjustment, seasonal run times, backflow test filed, warranty activated, and a walkthrough of the controller.
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 Herndon, we install and service irrigation systems in nearby Sterling, Chantilly, Fairfax and Centreville, and across Northern Virginia.
Every utility line is located before we plan a route. A licensed irrigator designs the system around your mature trees and established beds rather than through them. Head-to-head coverage is guaranteed, and dry spots that turn up later are corrected under warranty.
Soil moisture input, weather-driven scheduling and zone control, with WiFi available. On a part-shaded Herndon lot this matters twice over, because ground under a canopy stays damp long after the open lawn has dried out.
Experienced crews working carefully around established planting, so water is distributed efficiently and your finished Herndon yard is not torn up to achieve it.
The tie-in is made indoors or outdoors depending on how your plumbing runs. A master shut-off valve goes in where it can be reached quickly in an emergency.
Every system gets one. It stops used irrigation water being drawn back toward the potable supply. We install to the specification the local inspector will pass, then test and file the report annually.
Nearly always mounted inside the garage. Where that is inconvenient we will site it in a basement, a shed, or a weatherproof cabinet outdoors.
Irritrol, Rain Bird and Hunter parts, matched to the zone rather than bought in one size. Rigid PVC rather than the flexible tubing used to cut a bid. Rotors, matched precision sprays and drip line through planting.
The relationship continues after handover, with adjustments, repairs, seasonal services and future upgrades handled by the people who installed it.
A visit to measure the lot, check static pressure and flow, map any existing system and note where trees and beds constrain the layout. Written estimate inside 24 hours.
We obtain the required town or county permits and arrange utility locating, then install using the least intrusive method the site allows. Turf is lifted and relaid wherever we can, and every zone is tested before we leave.
Zone by zone testing, arcs and nozzles set, run times programmed for the exposure each zone actually has, backflow filed, warranty active, and a walkthrough with you.

Professional& ExperiencedQ: Is my Herndon home in the town or in Fairfax County?
A:Many homes with a Herndon mailing address, including Franklin Farm, Floris and McNair, are in unincorporated Fairfax County rather than the Town of Herndon. We confirm which applies to your address before pulling permits.
Q: Who handles the backflow test for my Herndon home?
A:Our DPOR certified backflow testers perform the annual test and submit the report to the right authority. Outside town limits, reports go to Fairfax County under its cross connection program.
Q: My system is decades old. Is it worth repairing?
A:Often, yes. If the pipe is sound, new heads, valves, nozzles and a smart controller can bring an older system back for much less than replacement. We test every zone and give you both options in writing.
Q: My yard is shadier than it used to be. Do I need a new system?
A:Not usually. We can re-zone or re-nozzle areas that have changed from sun to shade so they get less water, and move beds to drip.
Q: Can I control my sprinkler system from my phone?
A:Yes. We install WiFi controllers with weather-based scheduling that you can run from your phone.
Q: When should I winterize my sprinkler system in Herndon?
A:Plan for late October through November, before the first hard freeze. We clear every zone with compressed air and protect the backflow assembly.
