Irrigation contractors price service work as a service call plus an hourly rate, and new systems by the zone. Owners who state their prices charge $40 to $130 to send one tech out, which usually buys the first 30 minutes to an hour on site, then $80 to $150 an hour per tech. Two-person crews go out at $150 to $250 an hour. Installs run about $800 to $2,000 a zone, with the backflow assembly, the controller and the tap to the water supply priced on top. Plenty of owners hide the hourly rate inside a labor-included price per repair, so the customer sees "$50 a head" and never argues about minutes.

The price sheet works your own numbers out: an hourly rate from a year of costs and the hours you can bill, a service call, a contract rate, a price per zone from materials, markup and crew hours, a full system quote, and a repair price list you can print for customers. Get it two ways: make your own copy in Google Sheets or download the Excel version (.xlsx). Pick one, enter your email and I'll send the link.

The pages that rank for these questions are written for homeowners. Angi says a residential sprinkler system "costs about $2,549, but average rates vary from around $1,636 to $3,595," and that one zone costs $500 to $1,000, "with each additional zone costing an average of $1,000."⁵ That's what a homeowner expects to hear. The owners below quote $800 to $2,000 a zone before the backflow and the controller, so a six-zone yard comes out well above Angi's average. Price from your costs, and be ready to explain the gap.

Sprinkler repair pricing: a service call plus an hourly rate

The service call is the unit. It pays for the trip and a first block of time, often 30 minutes, sometimes an hour, and the clock runs after that. I read two years of r/Irrigation and the lawn subs, August 2024 to November 2026, for owners stating their own prices, and kept the comments whose own words place them as owners or as the people setting a company's prices.¹ Sixteen of them gave a service call, a first-hour charge or an hourly rate:

So: $40 to $130 to send one tech out, $80 to $150 an hour for one tech, $150 to $250 for two. I left out the one owner who charges $30 an hour because his customers are seniors on fixed incomes, and the people quoting what someone else charged them. The cheapest owners say so themselves. The $40-and-$80 owner calls it "low in my area," and he said it to a man charging $30: "That's crazy low unless it's all straight cash straight into your pocket. And commercial auto insurance and general liability isn't cheap."¹

Hourly or labor-included unit prices

Two camps. Time-and-materials owners bill the clock and mark up parts. A Connecticut owner bills $125 an hour with a one-hour minimum and quarter hours after that, and says most companies in his state "charge time n materials."¹ Unit-price owners quote one number per repair with the labor inside it. A Texas owner charges a $99 call and then $100 for a one-inch valve, $35 a spray head and $50 a rotor, labor included. Another owner explained why he prices repairs that way: "This means the price we quote is labor & materials included. All a tech does is count the number of valves, ID size of valves & pipe and if it's conventional or 2 wire. It keeps the customer bitching to a minimum."⁴

Unit prices are easier to sell and harder to get right, because each one hides an hourly rate and a markup. The price sheet's repair tab builds every unit price from a part cost, the minutes the job takes, a markup and your hourly rate, so a $45 spray head is a number you chose, not one you copied. On markup, owners who say so are all over the place: 50% or more in Texas, 150% on plastics for another, and 200% on standard parts but only 30% on brass for a Florida owner.⁴ Brass backflow parts cost enough that a plastic-parts markup on them looks like gouging on the invoice. If you bill time and materials, the free landscaping invoice template puts each part and each crew hour on its own line, with a tax mark per line.

Contract rate against non-contract rate

The North Carolina owner above charges $100 an hour, or $90 to customers on a contract.¹ A contractor who runs HOA work wrote out his split: "Each damage call is $75 (normal residential is $125) plus the repair fee," inside a base contract that pays for a start-up and a winter blowout assessment every year.³ That's the trade. The customer prepays the seasonal visits and gets a lower rate on repairs, and you get a book of customers who call you first when something breaks.

Keep the contract to visits you can count. Another owner who handles 55+ communities put it bluntly: "Set your price for an opening and closing and don't corner yourself by offering check-ups."³ An open promise of "check-ups" turns into unpaid trips. The landscaping maintenance agreement template has the seasonal scope table and the skip-visit rule; write your start-up, your blowout and your contract rate into it.

Sprinkler system installation: pricing per zone

New systems are quoted by the zone, with the parts that serve the whole system priced on their own lines. Ten owners gave a per-zone price:²

So about $800 to $2,000 a zone, and the system-level parts add real money: a backflow assembly at $350 to $1,000 installed (a one-inch pressure vacuum breaker at $350, labor included, from the Texas owner; a one-inch double check at $800; a PVB at $1,000), a controller at $250 to $500, and a supply valve or tap where the owner doesn't sub it to a plumber. A per-zone price that leaves those out is how a $7,000 job gets quoted at $5,000.

Working out your own numbers

Start from a year, not from the guy down the road. Add up what you need to pay yourself, the tax on it, and every cost of the business, then divide by the hours you'll actually bill. Irrigation is seasonal, so the hours are the hard part: an April-to-November season at 30 billable hours a week is about 1,000 hours, and the winter months carry costs with little work. One Southern California owner put the problem plainly: "sometimes I have to work 40 hours in a week in order to make 20 hours worth of income."¹

Insurance is a real line. A one-man Colorado irrigation owner pays $1,800 a year for general liability at $1 million per incident and $2 million aggregate, and "The killer now is 8800 year commercial auto policy for 2 trucks, 2 trailers,trencher and 185 compressor." A solo owner in central Florida pays about $500 a year for $2 million.⁶ Get your own quotes; contractor insurance covers what to buy first.

Here's the price sheet's example, with made-up costs except the insurance, which uses the Colorado owner's numbers (half of the auto policy for one truck):

Every yellow cell in the sheet is yours to change, and the repair tab turns your rate into unit prices: nozzle swaps, heads, rotors, valve rebuilds and replacements, line breaks, wire faults, controllers, rain sensors and PVB rebuilds. Print it as your price list once the numbers are yours.

Seasonal visits: start-ups and blowouts

Where the ground freezes, the spring start-up and the fall blowout are the two visits that come back every year. Owners charge $65 to $100 for a blowout, or $8 to $26 a zone with an $80 or $90 minimum, and $75 to $100 for a one-tech start-up.⁷ One owner with ten years in the trade who just formed his LLC settled on an annual contract of "about $250. That gives me $75 for a startup and $175 for a winterization."⁷ The steps, the compressor limits, more owner prices and a route sheet for both visits are on the sprinkler blowout and spring start-up checklist.

Backflow testing as a second line

Testing backflow assemblies is a separate book of yearly or multi-year visits, and the water utility or county writes the rules, not the state irrigation board. Raleigh requires a residential irrigation backflow assembly to pass a test "by July 1st every 3 years," and a commercial irrigation one every year by July 1; testers have to be City of Raleigh certified and registered.¹⁴ Fairfax County, Virginia wants every assembly tested by a certified tester every year, in a month assigned by the property's tax map grid, with the report filed within 10 business days.¹⁵ One Missouri irrigation owner subs his tests to a solo tester who "picked up around 100 customers his first year," and the catch is the utility: "The biggest hurtle is if your are requires testing and send out notifications. In my area if no notification is sent then people believe they don't have to have the device tested."¹⁶ Check your utility's program before you buy a test kit. In North Carolina the backflow assembly isn't part of the "irrigation system" the irrigation license covers, and a licensed plumber may install and repair it.⁸ In Virginia the irrigation specialty may install backflow devices only with board-approved training (below).

North Carolina: what the irrigation contractor license asks of you

North Carolina licenses irrigation contractors under Chapter 89G of its General Statutes, through the North Carolina Irrigation Contractors' Licensing Board (NCICLB). What a new license holder has to know, read on November 8, 2026:

• The $2,500 line. The license is required except for "Any irrigation construction or irrigation contracting work where the price of all contracts for labor, material, and other items for a given jobsite is less than two thousand five hundred dollars ($2,500)."⁸ All the contracts at one jobsite count together, so a repair that turns into a renovation can cross it.
• Who else may do the work. Licensed plumbers may do "installation, repairs, or maintenance of water mains, water taps, service lines, water meters, or backflow prevention assemblies supplying water for irrigation systems; or repairs to an irrigation system." General contractors with the building, residential or public utilities classification are exempt, and so are owners working on their own property.⁸
• To get the license: at least 18, three years of experience (two years of education counts as one), an exam, and a corporate surety bond or irrevocable letter of credit "in the amount of ten thousand dollars ($10,000)."⁸ The board also asks for a self-inking stamp or embossing seal with your name and license number; its fee list shows $100 to apply, $340 for the exam, $100 for the yearly renewal and $75 for the seal.⁹
• An LLC or corporation needs its own license. The board issues one when a licensed officer, manager or full-time employee is named on it, and "only the individuals licensed under this Chapter execute contracts." If that person leaves, you have 90 days to name another before the business license is suspended.⁸ The board's page: a corporate license "is required for those individuals that work for, or own a corporation, Limited Liability Corporation (LLC), partnership or other business entity that contracts irrigation through the business entity or advertises implying licensure," with a $100 application and a $100 yearly renewal.⁹
• The seal. It bears your name, license number and "N.C. Licensed Irrigation Contractor," and you may use it only while the license is valid. Display the license at your place of business.⁸
• Renewal and continuing education. Every license renews "on or before December 31 of each year," and a license that isn't renewed is revoked automatically.⁸ The board wants ten hours a year, "a combination of six (6) irrigation credits and four (4) business credits," and "Individuals licensed by Exam are not required to obtain CE in the licensing year that the exam was passed."¹⁰
• Rain sensors. 21 NCAC 23 .0509: "All automatically controlled irrigation systems shall include sensor or other technology designed to inhibit or interrupt operation of the irrigation system during periods of either adequate soil moisture or rainfall. Rain or moisture shutoff technology shall be installed according to the manufacturer's published recommendations."¹¹ Put one on every controller you install, and price it in.
• Complaints. You have to notify the board "by registered mail of any complaints filed against the contractor within 30 days from the date the complaint was filed." The board can fine up to $2,000 per violation of the chapter or its rules.⁸
• Spraying and landscaping. Applying pesticides "for compensation on someone else's property" takes a separate commercial ground applicator license from the NC Department of Agriculture (license type 026), which names landscapers and lawn care as examples.¹² Landscaping work of $30,000 or more on one job site in 12 months needs a license from the NC Landscape Contractors' Licensing Board; below that it's exempt.¹³

The bond shows up again on contractor insurance, with the other licenses that come with an insurance or bond condition. Texas, New Jersey, Louisiana and more than a dozen other states license or register irrigation work too; each state's rule is in lawn care and landscaping licenses by state.

Virginia: landscape irrigation is a contractor specialty

Virginia has no separate irrigation board. Irrigation work is a specialty on the state contractor license, "Landscape irrigation contracting" (ISC), which "provides for the installation, repair, improvement, or removal of irrigation sprinkler systems or outdoor sprinkler systems." The plumbing (PLB) and highway/heavy (H/H) classifications cover it too. On backflow, the regulation says ISC "may install backflow prevention devices incidental to work in this specialty when the installer has received formal vocational training approved by the board that included instruction in the installation of backflow prevention devices."¹⁷ The license class (C, B or A) sets how big a job you can sign, and a contract over $1,000 needs one; the $1,000 line and the class limits are on the Virginia handyman license page.

Where Deepsel fits

A spreadsheet is the right place to work your rates out. Charging them happens on a phone in somebody's yard. In Deepsel, each price book item has a name, a description that shows on the quote, a unit such as hour, zone or each, a price, and a cost the customer never sees; the edit screen shows the markup and gross margin those two give. Put in your service call, your hourly rate, your contract rate and your unit prices for heads, rotors and valves. Adding one to a job copies its name and price onto the line, an hourly line takes part hours such as 1.5, and quantities take decimals. A new-system quote can carry options, say a six-zone and an eight-zone layout, and optional lines the customer ticks when approving, such as a rain sensor upgrade or a smart controller, with an on-screen signature and an optional card deposit that comes off the final invoice. The terms text you write once is copied onto every new quote, so your license number goes there. What it won't do: work your rate out from your costs, mark parts up for you, design a system or count zones. The Free plan covers 30 estimates and 30 invoices a month for your whole team; Pro is $29 a month for unlimited estimates and invoices. Details are on the pricing page.

Free scheduling and invoicing apps for lawn and irrigation businesses are compared in free lawn care software and apps.

Frequently asked questions

How much do irrigation contractors charge per hour?

Most irrigation owners who state a rate on Reddit charge $80 to $150 an hour per tech, and $150 to $250 an hour for a two-person crew. A North Carolina owner charges $100 an hour, or $90 for customers on a contract; owners in Connecticut, Texas, Long Island and Southern California charge $125 to $150. Work yours out from a year of costs and the hours you can bill: with the example costs on this page and 1,000 billable hours, that comes to $110.

What is a typical sprinkler service call fee?

Owners charge $40 to $130 to show up, and the fee usually buys the first 30 minutes to an hour on site. A $50 call covers 30 minutes of troubleshooting for one owner; a $99 call covers the first 30 minutes for another, then $90 an hour; a North Georgia owner charges $130 for the first hour and $120 after. Some owners skip hourly billing and quote labor-included prices per part, on top of a $99 call.

How much should I charge per zone for a sprinkler system install?

Owners who quote by the zone charge about $800 to $2,000 a zone, with the backflow assembly, the controller and the tap to the water supply priced separately. A backflow assembly runs $350 to $1,000 installed in owners' quotes, and a controller $250 to $500. Price your own from the materials in a zone, your parts markup and the crew hours, which is what the free price sheet does.

Do you need a license to install irrigation in North Carolina?

Yes, for any job where the contracts for a jobsite total $2,500 or more. You need a license from the North Carolina Irrigation Contractors' Licensing Board, which takes three years of experience, an exam and a $10,000 surety bond or letter of credit. An LLC or corporation needs its own business license, and only licensed people sign its contracts. Licensed plumbers may do the tap and the backflow assembly and may repair systems, and general contractors with the building, residential or public utilities classification are exempt.

Who decides how often a backflow preventer gets tested?

The water utility or the county, through its cross-connection program, so the rule changes at the town line. Raleigh wants a residential irrigation backflow assembly tested by July 1 every three years and a commercial one every year. Fairfax County, Virginia wants every assembly tested every year, in a month assigned by the property's tax map grid, with the report filed within 10 business days. Testers have to be certified, and Raleigh wants them registered with the city.

How much should I mark up irrigation parts?

Owners who say so mark up common plastic parts 50% to 200%, and brass and other expensive parts far less: one Florida owner adds 200% to standard parts and 30% to brass, a Texas owner adds 50% or more, and another owner 150% on plastics. Others build the parts into a labor-included price per repair, so the customer never sees a markup line.
