When March arrives and you turn on your irrigation system, you want water flowing through your sprinkler heads—not bubbling up through your lawn from burst pipes. That’s exactly what happens when water sits in your system all winter, expanding and cracking everything it touches.
Professional winterization means your system gets properly drained using commercial-grade air compressors. Every zone gets blown out completely. Your water source gets shut down correctly. Your controller gets protected.
You wake up in spring knowing your investment is intact, not wondering how much the repair bill will be.
Rolling Hills Property Services has been protecting Suffolk County irrigation systems for years. We understand exactly when Long Island’s unpredictable weather demands winterization—and we know the specific challenges that Selden’s soil conditions and climate create for sprinkler systems.
Licensed and insured, we’ve built our reputation on transparent pricing and reliable service. No surprise fees, no shortcuts, no wondering if the job was done right.
When other property owners in Selden need their irrigation systems protected, they call Rolling Hills because they know the work gets done properly the first time.
First, we shut down your water source completely—no water flowing to the system during winter months. Next, your automatic irrigation controller gets turned off and protected from the elements.
Then comes the critical part: we connect commercial-grade air compressors to your system and blow out every single zone. This isn’t a quick pass-through. Each zone gets individual attention until every drop of water is removed from your underground pipes and sprinkler heads.
The process typically takes 2-4 hours depending on your system size. You get a clear timeline upfront, and we work efficiently without rushing through the details that matter.
When we’re finished, your system is completely winterized and ready to handle whatever Long Island’s winter throws at it.

Complete water source shutdown ensures no water enters your system during freezing months. Professional air compressor blowout removes water from main lines and every individual zone—the water that would otherwise freeze, expand, and crack your pipes.
Controller protection keeps your irrigation timer safe from winter weather and power fluctuations. We also inspect your system for any existing issues that could become expensive problems when spring startup happens.
In Selden’s climate, where temperatures can swing dramatically and freeze warnings come with little notice, this comprehensive approach is what separates professional winterization from DIY attempts that leave water hiding in your system. You’re not just getting a service—you’re getting insurance against thousands of dollars in spring repairs.
Schedule your sprinkler winterization between October 1st and November 15th, depending on Long Island’s weather patterns. You want to winterize before the first hard freeze, which typically happens when temperatures drop to 32 degrees Fahrenheit or below.
In Selden, this timing can vary year to year. Some years, you might need winterization by mid-October if an early cold snap hits. Other years, you might have until late November if temperatures stay mild.
The key is watching the forecast and scheduling before that first freeze warning. Once water freezes in your pipes, the damage is already happening. Professional companies like Rolling Hills Property Services monitor weather patterns and can help you time it perfectly for Suffolk County conditions.
Water left in your irrigation system will freeze when temperatures drop, expanding and cracking pipes, valves, and sprinkler heads. This isn’t a maybe—it’s physics. Water expands about 9% when it freezes, creating pressure that plastic and metal components simply can’t handle.
Come spring, you’ll discover cracked underground pipes, broken sprinkler heads, and damaged valves. These repairs often cost thousands of dollars because you’re not just fixing one component—the freezing damage spreads throughout your entire system.
Even worse, the damage makes your pipes brittle, so they’ll keep cracking from normal water pressure. What could have been prevented with a $200-300 winterization service becomes a complete system overhaul costing $3,000-5,000 or more.
While you can shut off water and drain some components yourself, proper winterization requires commercial-grade air compressors that most homeowners don’t own. These compressors generate the pressure needed to blow every drop of water from your underground pipes and sprinkler heads.
DIY winterization often leaves water trapped in low spots, pipe bends, and sprinkler heads. You think you’ve drained everything, but hidden water pockets remain. When those freeze, you get the same expensive damage as not winterizing at all.
Professional winterization in Selden costs $150-300 depending on your system size, while spring repairs from incomplete DIY winterization typically run $1,000-5,000. The math is pretty clear—professional service pays for itself many times over.
Professional irrigation system winterization typically takes 2-4 hours, depending on your system’s size and complexity. A basic residential system with 4-6 zones usually takes about 2 hours, while larger systems with 8+ zones or commercial properties may need 3-4 hours.
The process can’t be rushed because each zone needs individual attention to ensure complete water removal. Technicians systematically work through shutting off water sources, protecting controllers, and using air compressors to blow out each zone thoroughly.
We provide clear time estimates upfront based on your specific system. We work efficiently but never cut corners on the details that protect your investment. You’ll know exactly what to expect before we start.
Professional sprinkler winterization in Selden typically costs $150-300 for residential systems, depending on the number of zones and system complexity. This investment prevents spring repair bills that often run $1,000-5,000 when systems aren’t properly winterized.
Basic systems with 4-6 zones fall on the lower end of this range, while larger properties with 8+ zones or complex layouts cost more. Commercial properties require custom pricing based on system size and accessibility.
We provide transparent pricing with no hidden fees. You get an upfront quote that covers complete winterization—water shutdown, controller protection, and thorough air compressor blowout of every zone. Compare that to the cost of replacing cracked pipes and broken sprinkler heads, and professional winterization is the obvious choice.
Yes, you need professional winterization every single year in Selden’s climate. Long Island experiences freezing temperatures every winter, and even one freeze cycle can destroy an unprotected irrigation system. There’s no “getting away with it” for a year or two.
Some homeowners think mild winters mean they can skip winterization, but Suffolk County’s unpredictable weather makes this gamble expensive. A sudden cold snap in December or January can freeze your system overnight, causing damage that won’t show up until spring startup.
Annual winterization is preventive maintenance that protects your irrigation investment year after year. We recommend scheduling your winterization at the same time each fall—it becomes routine maintenance that prevents emergency repairs and keeps your system running reliably for decades.
