Quick Summary
Choose a sprinkler system contractor by verifying licensing and insurance, asking for a written design drawing before installation, and comparing quotes line by line on components, zones, and warranty. A qualified sprinkler system contractor measures your water pressure and flow rate, specifies matched heads from one manufacturer, and explains what happens after installation.
- Irrigation quality is largely decided during design, before any digging begins.
- Ask whether a permit is required and who is responsible for checking.
- Compare bids on specified components, zone layout, warranty, and exclusions, not just totals.
- Static water pressure and flow rate determine how many heads a zone can support.
- Skipping winterization is the costliest mistake, cracking backflow assemblies and manifolds.

What Separates a Sprinkler System Contractor From a General Handyman
A sprinkler system contractor designs, installs, and services irrigation systems. That distinction matters more than most homeowners realize, because irrigation sits at the intersection of plumbing, electrical work, and landscape design. Get it wrong and you inherit a system that waters unevenly, wastes money, or fails the first hard freeze.
At Metro Automated Sprinklers, we have over 30 years of expertise.
The core problem: irrigation work looks simple from the outside. A trench, some pipe, a few heads. But the decisions that determine whether a system performs, head spacing, pipe diameter, zone count, controller type, are invisible once the grass grows back.
Here is what most guides miss. The quality of an irrigation system is largely decided before a single shovel hits the dirt, during design.
Irrigation Contractor Questions to Ask Before You Sign
The right questions separate a professional from a salesperson. Ask them before you sign anything, write down the answers, and listen for specifics rather than reassurances. The goal is a repeatable vetting process you can run on every contractor you interview, not a one-off conversation.
Licensing, Insurance, and Permit Questions
Ask directly: "Are you licensed to do this work here, and can you show me the certificate?" Then verify it.
Ask whether a permit is required for the work and who is responsible for checking.
Experience and Reference Questions
Ask the contractor: "How many systems like mine have you designed?"
The Vetting Checklist
Use this list for every contractor you interview.
- Will you provide a written design drawing before installation?
- What is your warranty?
Red Flags in the Answers
U.S. Environmental Protection Agency WaterSense program maintains guidance on water-efficient irrigation and can help you frame questions about efficiency with any contractor you interview.
Residential Irrigation System Design: What a Real Plan Looks Like
A residential irrigation system design can include a measured property, a head layout, and a zone plan based on water pressure and flow.
How to Compare Sprinkler Installation Quotes Line by Line
Comparing sprinkler installation quotes means reading past the bottom-line number and checking what each bid actually includes.
Normalize the Bids First
Before you look at totals, compare what each bid specifies. A simple way to do this is to build a one-page comparison sheet with a row for each line item and a column for each contractor, then fill in what each bid specifies.
What to Compare, Line by Line
Use this checklist to compare bids side by side:
- What components are specified?
- What is the warranty?
Scope, Equipment, and Zones
Read the scope line by line and mark anything that is excluded. Equipment matters too: matched heads and valves from a single manufacturer, such as Rainbird or Hunter, behave predictably across a zone, while mixed brands spray at different rates.
Ask each contractor to explain the zone layout and why it fits your property.
Warranties, Exclusions, and Payment Terms
Ask what the warranty covers and for how long.
How to Weigh Price Against Value
Once the bids are compared, consider what is included, what is excluded, and what happens after installation. If you want to move from comparing quotes to requesting your own, you can contact us to start that conversation.
What a Sprinkler System Warranty Should Cover
A sprinkler system warranty should clearly state what is covered and for how long.
Labor Coverage Versus Parts Coverage
Metro Automated Sprinklers backs installations with a 5-year warranty.
Matching Equipment to Water Pressure, Flow, and Your Property
Equipment selection starts with two measurements: static water pressure and flow rate in gallons per minute. A contractor who skips these is guessing, and guessing produces misting heads, dry corners, or a system that cannot run two zones at once.
Static pressure tells you how much force the water arrives with. Flow rate tells you how much volume is available. Together they determine how many heads a zone can support and what pipe diameter keeps pressure loss acceptable across the run.
Then the property shapes the rest. A large, sloping yard with full-sun turf needs more zones and higher-flow heads than a compact lot with mature shade trees. New construction with bare soil installs differently than an established landscape where trenches must weave around root systems, sidewalks, and a play area.
Matched heads matter here. Using sprinkler heads from a single manufacturer, like Rainbird or Hunter, ensures spray patterns and precipitation rates align across a zone. Mixed brands spray at different rates, and the result is a lawn that is soaked in one spot and dry in another.
Water Efficiency, Smart Controllers, and Long-Term Savings
Water efficiency comes from three things working together: correct zone design, matched heads, and a controller that adjusts to weather instead of running a fixed schedule. Skip any one and you leave savings on the table.
Smart controllers use local weather data and soil moisture sensors to skip watering when rain is coming or when the ground is already wet. Over a season, that translates into fewer unnecessary cycles and a lower bill. The Alliance for Water Efficiency documents how weather-based irrigation control reduces outdoor water use compared with timer-only scheduling.
Efficiency also shows up in the details. Pressure-regulated heads prevent misting and runoff. Drip zones for planting beds deliver water to roots instead of spraying it into the air. A rain sensor shuts the system down during a storm.
For homeowners on well water, efficiency has a second dimension: staining. Products like Rid-O-Rust are among the products we use.
Installation Mistakes That Cost Homeowners Money
The most expensive installation mistakes are the ones you cannot see: undersized pipe, too few zones, and heads spaced for appearance rather than coverage. Each one forces the system to run longer to compensate, and longer run times mean higher bills.
Here are the mistakes we see most often:
- Skipping the design drawing. Without it, head spacing is guesswork and coverage gaps appear after the first dry week.
- Too few zones. One zone for the whole yard means full-sun turf and shade plants get identical water.
- Undersized pipe. Narrow pipe drops pressure along the run, so the last heads in a zone underperform.
- No backflow prevention. Beyond code requirements, a missing backflow device risks contaminating the household water supply.
- Buried wiring done carelessly. Poor splices fail after a season or two and are expensive to trace.
- No winterization plan. Water left in the lines freezes, expands, and cracks pipe and valves.
Watch out: the single costliest mistake is skipping proper winterization. A cracked backflow assembly or split manifold can mean a repair bill far larger than the service you skipped.
These are the most common installation mistakes we see, and what each one costs you.
| Mistake | Why it costs money |
|---|---|
| Skipping the design drawing | Head spacing is guesswork; coverage gaps appear |
| Too few zones | Full-sun turf and shade plants get identical water |
| Undersized pipe | Pressure drops along the run; last heads underperform |
| No backflow prevention | Risks contaminating the household water supply |
| Careless buried wiring | Poor splices fail after a season or two |
| No winterization plan | Water freezes, expands, and cracks pipe and valves |

Frequently Asked Questions
What should I look for when hiring a sprinkler system contractor?
Look for a contractor who offers custom system design and ask what the warranty covers. Also ask whether the contractor offers winterization.
What irrigation contractor questions to ask will reveal whether they are qualified?
Ask what brands they use and what their custom design process includes. Ask what the warranty covers.
How do I compare sprinkler installation quotes fairly?
Compare quotes on scope, not just the total. Ask what each quote includes and compare the specified components.
What should a sprinkler system warranty cover?
Ask what the warranty covers and for how long. Metro Automated Sprinklers backs installations with a 5-year warranty.
Is Rain Bird or Hunter better for a residential sprinkler system?
Both are reputable manufacturers and the right choice depends on your property and water conditions. Rain Bird offers a wide product line and strong coverage options for varied yard layouts. Hunter is known for durable rotors and efficient nozzles. What matters more than the brand is whether the contractor matches heads, nozzles, and pressure correctly. A well-designed system using either brand outperforms a poorly designed one using the other.
Should I hire a professional or install a sprinkler system myself?
Metro Automated Sprinklers offers professional installation and custom system design. The company backs installations with a 5-year warranty.
How long does professional sprinkler system installation take?
Most residential installations take one to three days depending on yard size, zone count, and whether trenching is needed. A small yard with four to six zones may finish in a single day. Larger properties with landscaping, sidewalks, or new construction may take longer. Ask the contractor for a written schedule and confirm how they protect existing grass and walkways during the work.
