A well-maintained irrigation system keeps your lawn healthy without the daily hassle—but only if it's installed and serviced by someone who knows what they're doing. Choosing the wrong contractor means wasting water, facing expensive repairs, or worse, watching your landscaping die mid-summer. Here's how to find and hire a contractor who'll get it right.
Verify Licensing and Insurance
Before anything else, confirm the contractor holds a valid irrigation license in your state. Requirements vary: some states require certification through the Irrigation Association, while others have their own licensing boards. Call your local water authority or check your state's contractor licensing website to verify credentials.
Request proof of liability insurance and workers' compensation coverage. A contractor without proper insurance puts you at financial risk if someone gets injured on your property or if they damage underground utilities. This typically costs a homeowner nothing but protects you from unexpected bills.
Get Multiple Quotes—and Compare Specifics
Get at least three written estimates before deciding. A basic sprinkler system installation for a residential lot typically runs $2,500 to $6,000, depending on yard size and complexity. Drip irrigation systems average $1,500 to $4,000. Smart controller upgrades add $300 to $1,200.
Don't just compare total price. Ask each contractor:
- How many zones will the system have?
- What type of sprinkler heads (rotary, fixed spray, drip tubing)?
- Is the estimate for labor, materials, or both?
- Will they handle permits and inspections?
- What warranty covers parts and labor?
A suspiciously low bid often signals corners cut on materials or missed coverage areas. A bid that's significantly higher may include premium components you don't need.
Check References and Past Work
Ask for at least three recent references—ideally customers with similar yard sizes and systems. Call them directly and ask:
- Did the contractor finish on time?
- Did the system work as promised after installation?
- Have they returned for maintenance or repairs?
Many experienced contractors showcase before-and-after photos on their website or social media. Look for evidence they work in your specific climate zone; someone experienced with desert irrigation may not understand freeze-line requirements in colder regions.
Understand System Design for Your Space
A quality contractor will visit your property to assess drainage, slope, soil type, and sun exposure before designing anything. They should also ask about your water pressure and whether your municipal water supply has restrictions during dry seasons.
Expect them to recommend zoning that separates plants with different water needs—turf, shrubs, and flower beds shouldn't be on the same zone. If a contractor quotes a system without an on-site visit, keep looking.
Ask About Maintenance and Support
Most contractors offer seasonal turn-on and turn-off services ($75 to $150 each). Ask if they provide winterization in your climate, as frozen sprinkler lines are expensive to fix. Some offer maintenance plans ranging from $300 to $800 annually that include adjustments, head cleaning, and early-season inspections.
Clarify response times for emergency repairs. A broken main line or controller malfunction during the growing season shouldn't leave you waiting two weeks for a callback.
Use Trusted Directories
When comparing options, platforms like Mercoly help you find and review trusted irrigation and sprinkler services providers side-by-side, making it easier to spot differences in pricing, availability, and customer feedback.
Red Flags to Avoid
Don't hire contractors who:
- Refuse to provide references or insurance information
- Won't visit your property before quoting
- Push high-pressure sales tactics or guarantee permanent solutions to water restrictions
- Don't mention system zoning or water audits
- Quote work without discussing your water pressure or soil conditions
Frequently Asked Questions
Q: How often should my sprinkler system be serviced? Most systems benefit from two service visits annually—a spring tune-up before heavy use and a fall winterization. Additional inspections after major storms catch damage early.
Q: Will a smart controller save me money? Smart controllers that adjust based on weather can reduce water usage by 15–30%, offsetting their $500–$1,200 cost within 1–2 years, especially in water-restricted areas.
Q: What's the difference between rotary and fixed-spray heads? Rotary heads cover larger areas (30–50 feet) and use less water per cycle, ideal for turf; fixed-spray heads work better for small planting beds and tight spaces but waste more water through overspray.
