Custom irrigation, built for St. Louis conditions

Green Turf is a St. Louis irrigation company specializing in custom sprinkler system design, installation, repair, and ongoing maintenance. We serve residential, commercial, and municipal properties across St. Louis County and St. Charles County, with five decades of in-house design and installation experience and roughly 1,500 households on our service membership.

Irrigation services we offer in St. Louis

Every property starts in a different place. Some homeowners need a system from scratch. Some inherited a system from a previous owner and need it back online. Some have a working system but want it maintained properly. We handle all of it.

Irrigation system installation

New residential and commercial sprinkler systems, designed in CAD to match your property’s grade, soil, and water pressure. Every install includes as-built documentation and a calibrated walkthrough before we leave the site.

Irrigation system maintenance and repair

Diagnostic visits, zone repairs, head replacements, controller troubleshooting, valve work, and full system tune-ups. Our service trucks carry stocked parts so most repairs finish in a single visit.

Service memberships

Annual programs covering scheduled tune-ups, spring startup, fall winterization, priority dispatch during peak summer, and discounts on parts and repairs. Roughly 1,500 St. Louis households are enrolled.

Backflow testing

Annual certified backflow testing for Missouri code compliance, available as a standalone service or bundled into membership plans.

Residential, commercial, and municipal irrigation in St. Louis

We design systems for the full range of property types across the St. Louis metro.

Residential

Our largest customer group is homeowners across St. Louis County and St. Charles County. The work ranges from single-zone front-yard systems on smaller lots in older suburbs like Webster Groves and Kirkwood to multi-zone installations on larger properties in Chesterfield, Wildwood, and Creve Coeur. Most of our residential clients come to us for the same reason: they want a system that performs reliably, protects the landscape they’ve invested in, and doesn’t need constant babysitting.

Commercial

Property managers, HOAs, business owners, and landscape contractors who need irrigation that performs across larger footprints. These projects require staged installation, zone-level reporting, and systems built to hold up under heavier use. We handle the documentation and scheduling these jobs require.

Municipal

We accept municipal irrigation projects through a formal bid process. These jobs come with compliance, documentation, and inspection requirements that few private-sector irrigation companies are equipped to handle. Our 50-year track record in the St. Louis area makes us a frequent shortlist candidate.

How we design and install your irrigation system

We follow the same approach on every project, from a single-zone install to a multi-acre commercial system. The depth of the process is the reason our systems still run reliably 15 and 20 years after installation.

Irrigation Company

Step 1, site evaluation. A senior estimator walks the property, measures water pressure at the source, notes grade and shade conditions, identifies water-source constraints, and asks about your goals. We don’t quote off photos or aerial views.

Step 2, custom CAD design. Your system is drawn in-house using actual measurements, not a generic template. We size pipe, space heads, and balance zones based on your specific property. Two yards next to each other rarely get the same design.

Step 3, utility location and permits. All underground utilities are located before any digging starts. If a permit or backflow inspection is required by your municipality, we handle the filing.

Step 4, installation. Crews flag zone heads in the yard for your approval before any trenching. We use machinery where it fits and hand-dig where it doesn’t, especially near established landscaping and mature root systems.

Step 5, calibration. Every zone is tested, head arcs and trajectories are dialed in, and the controller is programmed to a schedule that matches your turf type, soil, and St. Louis seasonality.

Step 6, walkthrough and as-built handoff. A technician runs the entire system with you, explains controller operation, and hands off your as-built schematic in both laminated and digital format.

The components and smart technology we install

Component quality is where most irrigation companies cut costs and where homeowners pay for it later. We don’t carry a single-brand lineup. We choose components by category, based on what holds up best in Missouri soil and climate conditions.

Sprinkler heads, valves, and controllers

We install Hunter, Rain Bird, and Toro components. The right brand depends on zone type, water pressure, and water source. We’ve been installing all three for decades and know which products fail and which keep running.

Smart controllers

We install Hunter Hydrawise smart controllers for homeowners who want weather-based scheduling, remote control from a phone, and real-time flow monitoring. For St. Louis specifically, smart controllers cut summer water bills measurably by skipping watering after rain and shifting cycles during heat waves.

Piping

We size pipe based on flow demand, not the cheapest option that fits the budget. Undersized pipe is the most common reason a system that worked at install underperforms two summers later.

As-built documentation, a real advantage

Every system we install is documented after install, with zone maps, valve locations, head placements, and measurements recorded in both a laminated paper copy that lives with your controller and a digital file stored in your Green Turf customer account. This is uncommon in residential irrigation and saves significant money on future repairs, because nobody is guessing where a valve sits when something needs attention five years from now.

Why 1,500 St. Louis households are on our irrigation membership

An irrigation system is a long-term piece of infrastructure. The systems that last 20 years are the ones that get serviced consistently. The ones that fail at year eight are usually the ones nobody touched between install and the first big breakdown.

Our Irrigation Membership Program exists to keep your system on the first track. Roughly 1,500 St. Louis households are currently enrolled, many of them with us for a decade or more.

What members get

  • Preferred scheduling during peak spring and summer, when call volume runs highest
  • Discounts on parts and repairs
  • Free or discounted system evaluations
  • Ongoing system monitoring and seasonal optimization
  • Spring startup and fall winterization handled on schedule, without having to call
  • Annual backflow testing options available

Why members stay

The membership pays for itself the first time something breaks during a Missouri July, when most irrigation companies are booked weeks out. Members get dispatched first. The same applies after a hard freeze damages a backflow preventer or when a controller fails the week before vacation.

What 50 years in St. Louis irrigation actually means

Fifty years in St. Louis

We’ve been designing and installing irrigation systems in the St. Louis metro since 1976. Conditions here are specific. Heavy clay soil affects infiltration rates and drainage. Freeze-thaw winters require proper system winterization. Late-summer heat puts irrigation under sustained demand for weeks at a stretch. A half-century of local work means we’ve seen what fails and built systems that don’t.

Long-tenured, in-house crews

Our service technicians average a decade with Green Turf and roughly 20 years in the irrigation trade. Our office staff averages 15 years with us. That kind of retention is rare in the trades and shows up in how cleanly your install runs, how accurately repairs are diagnosed, and how few callbacks we have.

We don’t subcontract installation. Every technician on your property works for Green Turf, wears the uniform, and answers to our service manager. Crews are certified, English-speaking, and trained to leave the property cleaner than they found it.

No shortcuts, even when nobody would see

Most of an irrigation system lives underground. That’s where corner-cutting happens and where it costs you later. We size pipe correctly, set head spacing to manufacturer specs, plan for drainage at low points, and pressure-test before backfilling. None of this is visible after the lawn grows back. It’s the difference between a system that runs for 20 years and one that needs major repair at year five.

As-built documentation included

Detailed as-built schematics for every system, in both laminated paper and digital form, stored in your customer account. Most irrigation companies don’t document at all. This is what saves you on every future service call.

Stocked service fleet, same-day repairs

We run 13+ fully stocked, radio-dispatched service vans across the St. Louis metro. That means the parts our technicians need to finish most repairs are already on the truck. No second appointment to come back with the right valve, no waiting a week for a part to ship. For most common issues, the problem gets diagnosed and fixed in one stop.

Real people answering the phone

Our office is staffed year-round during business hours. No answering machine during normal hours, no offshore call center. The person who books your appointment knows our crews and knows our trucks. We offer Saturday service at no additional charge, and your technician calls 30 minutes before arrival so you’re not stuck waiting through a four-hour window.

Licensed, certified, and accredited

  • Missouri State and St. Louis County certified
  • Minimum 11 certified backflow inspectors on staff
  • BBB accredited
  • Fully licensed, bonded, and insured

How we design and install your irrigation system

At first glance, many irrigation systems look similar. The difference becomes clear over time.

Lower-cost installations often cut corners in ways that aren’t visible right away. But with time, they show clear signs that lead to:

  • Poor water pressure planning
  • Incorrect pipe sizing
  • Improper head spacing
  • Lack of drainage considerations

These shortcuts even cause more problems such as:

  • Uneven watering
  • Frequent system breakdowns
  • Water waste and higher bills
  • Expensive repairs

Green Turf systems are designed differently.

We focus on:

  • Long-term reliability
  • Fewer breakdowns
  • Reduced maintenance needs
  • Lower total cost of ownership

A cheap installation may save money upfront, but not in the long run because it often leads to years of frustration. A properly installed system delivers consistent performance, long term savings, and peace of mind that every homeowner needs.

Frequently asked questions about irrigation in St. Louis

How much does it cost to install an irrigation system in St. Louis?

Installation cost depends on lot size, number of zones, water source, and whether the system requires a separate water meter. Most St. Louis residential systems fall within a typical range based on these factors. We provide a fixed, itemized quote after an on-site evaluation, so the number you see is the number you pay.

Do I need to winterize my sprinkler system in Missouri?

Yes. Missouri winters consistently drop below freezing, and water left in irrigation lines will expand and crack pipes, valves, and backflow preventers. Winterization, also called a blowout, removes water from the system before the first hard freeze. We handle winterization as a standalone service and as part of our membership program.

How long does irrigation installation take?

Most residential installations finish in one to three days, depending on system size and lot conditions. Larger commercial projects may take a week or more. The system is fully operational and calibrated before our crew leaves the property.

Will installation damage my lawn?

Trenching disturbs the surface along zone runs, but we use narrow trenchers that minimize lawn impact, and disturbed strips typically recover within a few weeks of normal watering. In landscaped beds and around mature trees, crews hand-dig rather than trench to protect roots.

Do you install smart sprinkler controllers?

Yes. We install Hunter Hydrawise smart controllers as standard on new systems and as a retrofit on existing systems. Smart controllers adjust watering based on weather data and let you control the system from your phone, which cuts water use during St. Louis spring rains and late-fall cool snaps.

Are you certified for backflow testing?

Yes. We have a minimum of 11 Missouri State and St. Louis County certified backflow inspectors on staff. Annual backflow testing is required in most St. Louis municipalities to remain compliant with the water utility, and we’re certified to test and submit results on your behalf.

How often does an irrigation system need maintenance?

A properly designed system needs two scheduled service visits per year, spring startup and fall winterization, plus a midseason check if you’re seeing brown spots or pressure changes. Our membership program bundles routine maintenance and adds priority scheduling during peak summer.
