I’m so glad I found Cary Sprinklers! Adam, the owner, is incredibly friendly, honest, and straightforward. He found several problems with our sprinkler system and was able to fix them for a very reasonable price. We had other companies come out who tried to upsell us on repairs costing thousands of dollars, so the difference was unbelievable. I have some experience in this field myself, so I know how to evaluate vendors and recognize when someone is being honest and when they’re simply trying to sell you more work. Adam was clearly focused on actually solving the problems rather than taking advantage of us. He saved us a tremendous amount of money, and we really appreciate it. Thank you so much, Adam, for your honesty, professionalism, and excellent work. Highly recommended!

This is the second time we have used Cary Sprinklers, and both times involved dirty digging and repairing complex leaks. The first was an underground valve leak and they put the dirt and our sod back as if it was their own home. The site around our second job by our backflow was also filled in nicely. Adam the owner, Matt the estimator, and Colby the irrigation magician were all great to work with. We think our irrigation in our box came apart when TOC main busted and the extreme pressure of 200+ psi was too much. Matt did a thorough job looking at our issue, answering all my questions about the possible TOC main break playing a part, and giving quote for the time he felt it would take. Keep in mind, this is the type of small business where you need to be flexible on the time of arrival since prior jobs may put them behind. With this said, the crew will spend all the time needed to repair the issue you have at your home and not rush to make things just good enough. They want to make sure the repair is done to your satisfaction. I texted Adam several times and he had a prompt response time. He was also prompt via email with a post work invoice question. We recommend supporting Cary Sprinklers for the reasons above and because this is a small business growing roots in our community.

Adam and Gerald showed up right on time and kept me updated with texts the night before and the day of with their ETA. I needed a new zone added for part of the yard that wasn’t getting enough water anymore, and they did a great job. Fair pricing, excellent communication, and very professional — I’m really happy with the result.

5 stars — Highly recommend Cary Sprinklers! We hired Cary Sprinklers to expand our existing irrigation system by extending one zone and adding a completely new zone. From the beginning, they were professional, knowledgeable, and very easy to work with. What really impressed us was the equipment and efficiency. They used a Toro Dingo to trench the new lines, which allowed them to get the work done quickly and professionally while keeping the disruption to our yard to a minimum. The crew clearly knew what they were doing, and the installation was done right. Adam took the time to explain what we needed and why, and the communication throughout the project was excellent. The new zones give us much better coverage of the property, and everything is working exactly as it should. We couldn’t be happier with the finished system. The whole process was smooth, and the work exceeded our expectations. We would definitely use Cary Sprinklers again.

Cary Sprinklers is amazing. Adam is professional, capable, and wonderful to do business with. We called him because we had trouble with our timer app and controller. It wasn’t a brand that he usually works with, but he figured it out and fixed it anyway. Additionally, his team did an amazing job removing this massive root to get a broken sprinkler out of the ground and replace it and even under budget! I’ve done business with a few sprinkler companies in my lifetime, and these guys are the best!! They are honest, reliable, and very detail oriented. You will not be sorry if you call Cary Sprinklers.

Sprinkler repair

Sprinkler repair in Cary & Raleigh — heads, nozzles & coverage

Big or small, fixed right the first visit with genuine Hunter, Rain Bird & Toro parts.

Broken & snapped heads

A mower wheel, a truck tire in the driveway strip, or a shovel during bed edging snaps the riser and a head geysers or dribbles. We swap in a matched Hunter, Rain Bird, or Toro head at the right height so the spray clears the turf instead of hitting the crown.

Misaimed & sunken heads

Wake County clay heaves and settles, and heads slowly tilt or sink until half the arc waters the sidewalk. We reset each head plumb and dial the arc and radius back to the pattern the zone was designed for.

Clogged & stuck nozzles

On Cary’s reclaimed streets the purple-pipe water packs fine grit into nozzles and stalls rotors weeks before a potable system would notice. We pull and clean the nozzle and filter, flush the line, and reseat a matched nozzle so the rotor turns again.

Dry spots & uneven coverage

A brown crescent between two heads usually means one head is throttled, misaimed, or wearing the wrong nozzle for the spacing. We check precip rate and spacing across the zone, then correct nozzles and pressure so head-to-head coverage returns.

Leaking heads & seals

A head that weeps after the zone shuts off, or a soggy patch that never dries, is a worn wiper seal or a cracked body letting water past. We replace the seal or the head and confirm the zone holds pressure and drains clean.

High-efficiency nozzle upgrades

Older fan-spray nozzles throw water faster than clay can take it, so half runs off toward the curb. Matched-precip rotary nozzles slow the application, cut runoff on tight soil, and keep you inside your town’s watering window.

Signs it’s time for a look

  • A brown patch that stays crisp while the rest of the lawn is green
  • One zone that won’t come on or won’t shut off
  • A head spraying the driveway, fence, or street instead of turf
  • Spray heads that mist or fog instead of throwing a solid stream
  • A rotor that used to turn and now just sits and dribbles
  • A soggy spot or pooling water long after the cycle ends

The calls come from every kind of yard: the homeowner with one dry stripe the sprinklers keep missing; established systems in MacGregor Downs and Lochmere losing heads and valves to age and shifting clay; builder-grade systems in the newer sections that never quite covered right from day one; and the HOAs and property managers who need common areas green and the backflow paperwork clean. Different starting points, same finish — every zone running the pattern it was designed for.

Most sprinkler repair here is a single-visit job — a broken head, a clogged nozzle, or a misaimed arc is usually diagnosed and fixed the same trip, because we stock the common parts for these neighborhoods on the truck. Bigger work gets a firm, free estimate before we start, and the price you approve is the price you pay. Every repair is backed by our 100% satisfaction guarantee and 12-month workmanship warranty — and because we’re local, Preston, Amberly, Lochmere, and the surrounding Cary neighborhoods usually get a quick window, and Raleigh calls run on the same daily routes. And if you got here by searching “sprinkler repair near me” — you found us. Call or text Adam at 919-341-9644.

Not sure which water you’re on? Open a valve box and look for purple — purple pipe, tape, or lids means reclaimed water, common in neighborhoods near the North and South Cary water reclamation facilities, and it fouls nozzles and filters faster than potable water. It also exempts you from the alternate-day schedule. Most Cary homes are on standard potable water; we service both correctly and keep the two strictly separated.

Deeper problems have their own pages: heads that weep after shutoff · a zone that won’t run · weak pressure & coverage · emergency repair. Outside Cary? Raleigh · Apex · Morrisville · Holly Springs · Fuquay-Varina.

Irrigation repair

Irrigation repair in Cary & Raleigh — valves, wiring & mainlines

Searching “irrigation repair near me”? You found us — and when the problem is bigger than a head, we diagnose at the system level and fix the cause.

Valves stuck open or shut

A solenoid that won’t open leaves a zone bone-dry, while a valve stuck open runs all night and drives up the bill. On Cary’s reclaimed lines the extra grit chews up diaphragms faster, so we rebuild or swap the valve and confirm it seats clean.

Mainline & lateral breaks

A cracked PVC mainline pushes water to the surface and drops pressure across the whole yard; a broken lateral just starves the heads downstream. We trace the break, cut back to sound pipe, and repair with matched fittings so it holds in tight clay.

Controller & timer faults

When zones fire at odd hours or skip entirely, the culprit is usually the controller, a blown station output, or a scrambled program. We test each station, replace the failed part, and reset the schedule to your town’s watering days.

Field wiring & shorts

A nicked common wire or a corroded splice will kill a zone or trip the whole system, and roots in older neighborhoods work weak connections loose. We chase the short, re-splice with waterproof connectors, and get the field wire reading clean.

Backflow & RPZ repair

Cary requires a working backflow preventer on every system, so a leaking or failed RPZ isn’t just a puddle — it’s a compliance problem. We rebuild or replace the assembly and get it ready for its next required test.

System-wide low pressure

If every head is barely misting, look upstream: a partly closed valve, a clogged filter, or a hidden mainline leak. Reclaimed water loads nozzles and filters with mineral scale, so we clear the restriction and check precip rate zone by zone.

Signs the problem is system-level

  • A zone that never gets a drop while the rest run fine
  • A water bill that jumped with no change in habits
  • Heads barely misting from weak pressure
  • A patch of yard that’s always soggy
  • Sprinklers running at the wrong hour or not at all
  • Nozzles crusted over and spraying sideways

Most irrigation repair is still a same-visit job — a stuck valve, a shorted wire, or a single lateral break gets diagnosed and fixed in one trip. A mainline break under a driveway or a full manifold rebuild gets quoted upfront and scheduled so you know the timeline before we start. The estimate is free, and reclaimed-system work includes the extra filter and separation care the Town requires.

On cost: a single valve rebuild is a different job than tracing a mainline break across the yard, so you get an exact number for the actual fix before we dig — never a vague range, never parts you didn’t need. If a part has to be ordered, we tell you that day rather than stringing it out, and we don’t leave a zone half-working. When the diagnosis points somewhere unexpected — a pressure problem upstream, or a drainage issue that only looks like irrigation — we say so and price that instead.

Neighborhood age tells us a lot about what’s underground before we ever open a valve box. MacGregor Downs, Lochmere, and Regency run some of the town’s oldest buried plumbing — brittle poly, first-generation valves, splices that have sat wet for decades — while Preston and Cary Park are in the middle years where solenoids and controllers age out, and Amberly’s newer builder systems mostly bring wiring shortcuts and undersized manifolds. Walking in already knowing that is half the diagnosis.

What separates a repair that holds from one that comes back next season is diagnosis, not parts-swapping — anyone can replace a valve; finding the one that’s actually failing takes running the system and reading it. Before you hand anyone a wrench, ask what we’d ask: fully insured in North Carolina? Genuine manufacturer parts, or generic swaps? Will they run each zone with you before quoting, and is the labor warrantied in writing? We’re comfortable answering those from either side of the clipboard.

Cary & Raleigh don’t share a rulebook below the surface

  • Two water systems, one standard: a valve, manifold, or backflow repair on a reclaimed line is held to the Town’s strict separation rules — no cross-connections, ever.
  • The schedule lives in the controller: potable systems water on Cary’s year-round alternate-day schedule, set by street address (reclaimed users are exempt), and Raleigh keeps its own watering rules — so every controller fix ends with the program set to the calendar that applies at your address.
  • Backflow is part of the buried system: statewide, NC Senate Bill 166 puts every system on a required test cycle — Cary’s runs three years residential, annual with a booster pump or chemical feed — and we leave the assembly test-ready.
  • Raleigh runs on RPZs: Raleigh Water requires an RPZ assembly on irrigation, tested to the City’s July 1 deadline — a failing one is a repair we make before it becomes a compliance letter.
  • Underground work meets town spec: in-ground systems are permitted to local design standards, and our valve, pipe, and wiring repairs keep them that way.

Specialist pages when you already know the fault: valve repair · main line breaks · leak detection · wiring & electrical · pump repair. Beyond Cary, the same trucks cover Raleigh · Apex · Morrisville · Holly Springs · Fuquay-Varina.

Sound familiar?

A brown patch. A soggy corner. A water bill that doesn’t add up.

Most calls we get start with a small mystery, not a catastrophe. The lawn is green except for one crescent that stays crisp no matter how long the system runs. A head fires sideways into the driveway. One zone never comes on — or never shuts off. The side yard squishes underfoot three days after the last rain. None of it looks urgent, so it waits — and Triangle clay makes waiting expensive, because water that isn’t going where it should is either drowning roots, undermining a walkway, or leaking underground on your dime.

Each of those symptoms has a specific cause, and finding it is most of the job. Here’s where we usually start:

  • A dry patch that won’t green up is almost never dead grass — it’s coverage. A misaimed head, a clogged nozzle, or spacing that never overlapped. That’s sprinkler repair.
  • A zone that won’t fire — or won’t stop usually traces to a valve, solenoid, or wire, not the heads. See zone repair.
  • A water bill that jumped with nothing visible points to an underground leak. We locate it before anyone digs.
  • Standing water or a spongy lawn is a drainage problem clay loves to create — solved with French drains and grading, not more mowing.
  • A letter from the town about backflow testing has a deadline behind it. We test, repair, and file so your account stays clear.
  • A controller you fight with every season can be replaced by one that reads the weather and quietly trims the bill.
Why us

Local, accountable, and easy to reach

Most companies send a rotating crew or an apprentice learning on your system. We don't. You get the same experienced local team on every visit, standing behind the work — which is why it holds up and the estimate matches the invoice.

We've spent 10+ years on Triangle irrigation — reclaimed and potable water in Cary, Raleigh Water's backflow rules, and the heavy clay that makes drainage its own specialty. That local know-how is the difference between a real fix and a guess.

The six towns we serve don’t play by one rulebook. Cary runs alternate-day watering and serves some streets reclaimed water through purple pipe that clogs nozzles faster. Raleigh requires an RPZ backflow assembly tested on a City deadline. Fuquay-Varina wants that test every single year. A company that treats the Triangle as one market gets those details wrong — and you get the callback, the failed inspection, or the fine.

The other thing a decade here teaches: diagnose before you dig. Most of what looks like a sprinkler problem is a symptom — of pressure, wiring, grading, or scheduling. Finding the real cause first is why our repairs hold, and why we’ll tell you honestly when the cheap fix is the right one.

Season by season

A year in a Triangle yard

Irrigation here isn’t a set-it-and-forget-it system, because our weather isn’t. Clay that bakes hard in July swells all winter, and one March freeze can undo a careless fall. Here’s the rhythm we work to:

Spring is startup season — pressurizing mainlines slowly, walking every zone, and catching the freeze damage before it becomes a July emergency. It’s also when the towns’ backflow test letters land in mailboxes. Summer is repair season: dry patches show themselves fast in ninety-degree weeks, hidden leaks announce themselves on the water bill, and coverage problems that hid all spring turn brown and obvious. Fall belongs to two things — winterization before the first hard freeze, and drainage work while the ground still digs clean, so French drains go in ahead of the wet season instead of during it. Winter is when we fix what fall revealed: standing water, downspouts dumping at the foundation, crawlspace moisture — and when planning a spring installation or system revamp gets you on the calendar before the rush.

If you only remember one date: winterize before Thanksgiving. A cracked backflow assembly is the most common — and most avoidable — repair we make every spring.

Questions

Quick answers before you call

Do you offer free estimates?

Yes. Call, text, or send the form and we’ll get you a clear price before any work begins — on repairs, that usually means same-visit diagnosis and a number you approve on the spot. The estimate costs nothing and the invoice matches it.

Which areas do you serve?

Cary is home base, and we work daily in Raleigh, Apex, Morrisville, Holly Springs, and Fuquay-Varina — plus the surrounding Wake County area. Each of those towns has its own watering schedule and backflow rules, and we keep systems compliant with all six.

Do you really handle both irrigation and drainage?

Yes, and the two are more connected than most people expect. A soggy corner can be a drainage problem, a leaking lateral line, or an overwatering schedule — three different fixes that look identical from the surface. Because we do both, you get one diagnosis instead of two contractors pointing at each other.

What brands do you work on?

Hunter, Rain Bird, Toro, Irritrol, and Rachio, among others — and we stock the common heads, nozzles, and valves on the truck, so most repairs finish in one visit. Discontinued parts get matched to a current equivalent that drops right in.

How fast can you get out to me?

We respond the same business day, and water-wasting emergencies — a mainline break, a zone stuck on — go to the front of the line. Seasonal work like winterization and spring startup books ahead, so a little notice helps there.

Are you insured?

Fully — insured in North Carolina, with backflow work done to each town’s code and filed with the town. Every job is backed by a 100% satisfaction guarantee and a 12-month workmanship warranty.

What does sprinkler or irrigation repair cost?

It depends on the actual fault — a clogged nozzle or a single solenoid is a small job, while a mainline break or a manifold rebuild takes more parts and labor. We diagnose first, then give you a free upfront price for the actual fix, never a vague range, and the invoice matches the number you approved. Genuine parts and the 12-month workmanship warranty are included, not add-ons.

How long does a repair take?

Usually one visit. A broken head, a clogged nozzle, a stuck valve, or a shorted wire is typically diagnosed and fixed in a single trip. Bigger work — like a mainline break under a driveway — gets a firm timeline with the quote, and if a part needs ordering you’ll know before we leave.

Can you repair a cracked or leaking pipe?

Yes — pipe repair is one of our most common calls, whether it’s a PVC mainline break or a split poly lateral. We cut back to sound pipe, splice in matched PVC or poly fittings, and pressure-test the zone before we backfill.

A zone is stuck on and won’t shut off — what’s wrong?

That’s usually a valve diaphragm held open by debris or a failed solenoid — on reclaimed lines, grit is often the culprit. We rebuild or replace the valve, confirm it seats clean, and get your controller back on its proper schedule.

My street has purple pipes — is my system different?

Yes. Purple pipe means Cary’s reclaimed water, which carries more grit and minerals and clogs nozzles and filters faster than potable lines. We clean the filters, use matched nozzles, and keep the reclaimed and potable sides strictly separated — and reclaimed users are exempt from the alternate-day schedule.

Do I need a backflow test with my repair?

Sooner or later, yes — North Carolina keeps every irrigation system on a testing schedule. Cary asks every three years for most homes (yearly if you have a booster pump or chemical feed), and Raleigh Water requires an RPZ tested to the City’s deadline. We can check your assembly during the repair and tell you exactly where you stand.
