How Do You Find a Great Sprinkler System Installer?
The best sprinkler installers measure your water pressure and design from a site assessment, include backflow prevention and permits, and use Hunter or Rain Bird components on systems that run $1,800 to $12,000 installed. A well-installed irrigation system runs efficiently for many years; a poorly designed one wastes water, creates dry spots and soggy areas, damages plants, and requires expensive corrections. Because the system goes underground, the quality shows up in the first season of operation rather than on installation day.
They Design from a Site Assessment, Starting with Water Pressure
Supply pressure determines how many heads can run per zone, what head types are appropriate, and whether the supply can carry the system without a pressure booster. An installer who designs without measuring supply pressure at the point of connection is guessing.
A quality contractor visits the property, measures working water pressure and flow, assesses soil and terrain, maps the landscape areas needing coverage, and produces a zone-by-zone head layout before quoting. This design step is what separates professional irrigation contractors from landscapers who add sprinklers as a sideline. Ask whether they will perform a pressure test before finalizing the zone layout and head specifications. EPA WaterSense recommends about one inch of water a week, avoiding midday watering, and weather-based controllers to cut waste.
They Include Backflow Prevention and Pull Permits
Both are non-negotiable. Backflow prevention is required by code everywhere and protects your home’s drinking water supply. Permits ensure the work is inspected and code-compliant, which protects you at resale and on insurance claims. An installer who suggests skipping either to reduce cost is creating liability and is not worth hiring at any price. The best installers include both as a matter of course and can explain the local permit process and inspection requirements without prompting. Confirm whether obtaining the permit is the installer’s responsibility.
They Use Recognized-Brand Components
Hunter, Rain Bird, Toro, and Orbit are the major recognized irrigation manufacturers, with extensive dealer networks and parts availability. Valves, heads, and controllers from established manufacturers outperform generic equivalents in both longevity and repairability. A system installed with off-brand or unknown-manufacturer heads and valves may be impossible to repair with available parts in 5 to 10 years. Ask specifically which brands and models the installer uses; one who can name them and explain why is demonstrating product knowledge, while one who is vague may be using whatever is cheapest. (For more on this, see Questions to Ask a Sprinkler System Installer.)
They Are Licensed and Insured for Irrigation Work
Most states license irrigation contractors separately from general landscaping, because the connection to the potable water supply requires licensed work. Verify the appropriate state license for irrigation, plus general liability and workers compensation insurance. Licensed contractors are held to installation standards and have recourse mechanisms if their work is disputed; unlicensed operators do not. Insurance protects you if the property is damaged during installation.
They Provide a Zone Layout Map
A quality installer delivers a scaled drawing or digital map showing each zone’s coverage area and the location of heads and valve boxes. This document is essential for future repairs, adjustments, and winterization. An installer who does not provide it leaves you without the information needed to maintain your own system.
They Offer Ongoing Service
The best relationship with an irrigation contractor does not end at installation. An installer who offers spring startup and fall winterization, knows your system because they built it, and returns promptly when problems arise is worth more than the lowest bidder who finishes and moves on. An in-season failure during peak summer can stress or damage a lawn quickly. Ask whether they service what they install and what their response time is for in-season problems.

Sprinkler System Cost at a Glance
| Scope | Installed cost |
|---|---|
| Per zone | $500 to $1,000 (most yards need 4 to 8 zones) |
| Small-yard full system, simpler layout | $1,800 to $3,500 (even a small yard needs three or four zones) |
| Large or complex system | $5,000 to $12,000 (eight to twelve zones; a full acre runs about $10,000) |
Cost figures on this page were checked against published pricing on September 2, 2026. How we source cost data.
Overall range: $1,800 to $12,000 for a new in-ground system installed, averaging $3,500. The top of the range covers many zones, smart controls, or difficult terrain. Repairs to heads, valves, and lines cost far less than a new install.
Warning Signs in the Quoting Process
Several things during quoting identify a contractor worth avoiding:
- A quote given over the phone or by email without a site visit. That is an estimate, not a design. Either the price will be wrong or the system will not be optimized for your property.
- No controller brand and model specified. Controllers range from $50 basic timers to $300 smart units, and the difference affects years of water use and system performance.
- No explicit mention of the backflow preventer. If it is not named, you do not know it is included.
- No mention of permits. The contractor is either assuming you will pull them or planning to skip them.
Treat an extremely low quote as something to scrutinize rather than celebrate. Below-market irrigation pricing usually reflects low-cost generic components with limited parts availability, a design that under-zones the property to cut material and labor, installation without permits to avoid fees and inspection, or simple inexperience. Irrigation quality differences are hidden under the turf and do not surface until the system fails or wastes water, and the cost of a failed zone design or a rework a few years in exceeds the initial savings by a wide margin.

Comparing Installers Before You Sign
Get at least two or three quotes and compare them on site-based design, backflow and permit inclusion, component specification, licensing and insurance, and ongoing service commitment — not on price alone. Once scope is equalized, the price gap between a thin bid and a complete one is usually smaller than it first appeared.
Read reviews from customers with established systems. Irrigation quality shows over a season of use, so reviews from people who have run a system through a full year including a winterization are the most informative. Look for comments about dry zones, soggy areas, or coverage problems that emerged after installation, which indicate design flaws. Reviews mentioning responsive service when a head was hit by a mower or a zone stopped working indicate an installer who stands behind the work.
Get the scope in writing. The proposal should specify materials, labor scope, timeline, what is included (permits, cleanup, disposal), and warranty terms. For any project over $500, written scope is non-negotiable.
Tie payments to milestones. A reasonable schedule is a deposit at signing, a payment at material delivery or project start, and final payment at completion after a walkthrough confirms satisfaction. A contractor who requires full payment before work begins is a red flag in any trade.
Frequently Asked Questions
Look for a licensed irrigation contractor who measures supply pressure and designs from a site assessment rather than a phone estimate, includes backflow prevention and pulls permits as standard, uses recognized-brand components such as Hunter, Rain Bird, or Toro, provides a zone layout map, and offers startup and winterization service.
Do you measure water pressure before designing the zone layout? What brands and models of heads, valves, and controller do you use? Are you licensed for irrigation installation in this state? Will you pull the required permits? Do you provide a zone layout drawing after installation? What is your warranty on parts and labor?
Both are required by code. Backflow prevention protects your home's drinking water supply, and permitted work is inspected and code-compliant, which protects you at resale and on insurance claims. An installer who suggests skipping either to cut cost is creating liability for you.
Hunter and Rain Bird are the two dominant professional irrigation brands used by licensed installers, both with extensive dealer networks and replacement parts availability. Toro is a quality alternative, and Orbit is a widely available retail brand common in DIY installations. Any professional installation should use Hunter or Rain Bird as the primary component brands.
$1,800 to $12,000, averaging $3,500. Installed cost runs $500 to $1,000 per zone and most yards need 4 to 8 zones. Simpler small-yard systems land at $1,800 to $3,500, while large systems with many zones, smart controls, or difficult terrain run $5,000 to $12,000 or more.
One year on labor and parts from the installer, plus the manufacturer warranty on components, typically 1 to 5 years on heads and 1 to 3 years on valves and controllers. Ask specifically what the labor warranty covers, including head adjustment, zone valve replacement, and controller issues rather than just pipe leaks.
Rarely. Quality differences are hidden under the turf and do not appear until the system fails or wastes water. Cheap systems often use off-brand components that are unavailable for replacement in 5 to 10 years, and poor zone design produces dry spots and overspray that cost more in water and lawn repair than the installation savings.
Ideally yes. An installer who offers spring startup and fall winterization, knows your system because they installed it, and returns promptly when problems arise is worth more than the lowest bidder who installs and moves on. Summer irrigation failures stress turf quickly, so response time matters.
