New construction or an established landscape?

The first question shaping your project is what is already in the ground. Brentwood has both new homes with bare or freshly sodded yards and established properties with decades of mature trees, beds and hardscape. The two call for different approaches.

New construction is the simplest case. With little landscaping in place, the designer can lay out zones freely and coordinate with the landscape plan. If you can, bring the irrigation contractor in before final grading and sod, so sleeves under driveways and walks can be placed early.

Retrofitting an established landscape takes more care. Pipe has to route around large tree roots, under or around existing hardscape and through mature beds. The crew's methods matter: narrow-trench equipment, careful restoration and a design that works with existing plantings rather than against them.

If you already have an older system that underperforms, ask whether a renovation makes more sense than a replacement. Aqueduct, for example, says it can assess what is worth keeping, replace outdated components and redesign zones that are not providing adequate coverage.

System features worth considering

A modern residential system is more than heads and a timer. Know these options before you sit down with a designer:

  • Rotors and spray heads: rotors for large open lawns, spray heads for smaller and narrower areas. Each zone should use one type, not a mix.
  • Drip irrigation: for foundation plantings, beds, vegetable gardens and slopes. It puts water at the root zone with far less runoff and evaporation than overhead spray, which suits Brentwood's clay hillsides.
  • Smart controllers: devices that connect to local weather data and adjust watering for rainfall, temperature and evapotranspiration. Aqueduct says it recommends and installs Rain Bird's WiFi-enabled line and Hunter's Hydrawise platform, with smartphone control.
  • Rain sensors and pressure-regulating heads: small additions that prevent watering in the rain and keep spray patterns clean.
  • Backflow preventer: required by local water utilities on systems connected to the municipal supply, according to Aqueduct, which installs one with every new system.

Questions to ask every installer

Use the same list with every company, so the answers are comparable:

  1. Will you visit the property and produce a written, zone-by-zone design?
  2. Do you measure my water pressure and flow before finalizing the design?
  3. How do you zone turf, shrubs and drip, and how do you handle slopes and shade?
  4. What brands and grades of parts do you install?
  5. Who calls Tennessee 811 for utility locates?
  6. What trenching method do you use, and how do you restore the lawn?
  7. Is the controller a smart, weather-based model, and will you show me how to program it?
  8. Is the backflow preventer included, and who handles the initial compliance testing?
  9. What warranty covers parts and labor, and what do manufacturer warranties add?
  10. Are you licensed and insured, and do you service the systems you install?

Pay attention to how each company answers, not only what it says. A contractor that explains its design reasoning, mentions your slopes and trees without prompting and is specific about parts is showing you how it will approach the job. Vague answers before the sale rarely turn into precise work after it.

The last question deserves weight. A company that also services and maintains systems has a reason to install them in a way that is easy to repair later.

How to compare quotes fairly

Sprinkler quotes vary for legitimate reasons: number of zones, amount of drip, controller type, length of pipe runs, the difficulty of the terrain and the grade of components. A lower number can mean fewer zones, wider head spacing that leaves dry spots or consumer-grade parts. A higher number can mean better coverage and longer life.

To compare like with like:

  • Line up zone counts and what each zone covers.
  • Check head spacing for head-to-head coverage.
  • Compare the controller model and whether it is weather-based.
  • Confirm what is included: backflow device, rain sensor, drip zones, lawn restoration.
  • Compare warranty terms in writing.

Be cautious of firm prices quoted over the phone without a site visit. Aqueduct, for instance, says it provides detailed written estimates only after an on-site consultation, because property size, complexity, water pressure and zone count all drive the cost.

What to expect once you sign

For sprinkler system installation in Brentwood, TN, the typical sequence after signing is: utility locates, verification of water supply and pressure, trenching and pipe installation, heads and drip, then controller and backflow, followed by testing and an owner walkthrough. Aqueduct says most residential jobs are completed in one day, with larger properties taking two to three.

On installation day, make sure gates are open, pets are secured and vehicles are out of the work area. Point out anything underground the locate service will not mark, such as private landscape lighting cables, invisible pet fences or drainage lines.

It also helps to clear anything movable from the planned pipe routes, such as planters, garden ornaments and outdoor furniture, and to let neighbors know if crews will be working near a shared property line.

At the walkthrough, ask the crew to run every zone with you, show you how to change the schedule and give you a zone map for your records.

Planning for the first year

New systems need the most attention in their first season. New sod needs frequent, short watering at first, tapering off as roots establish; ask your installer for a starting schedule and when to change it. Watch each zone run a few times in the first weeks and report dry spots or soggy areas while the crew can still adjust heads easily.

Before the first hard freeze, the system must be winterized: water off, backflow drained and lines purged with regulated air. In spring it needs activation and inspection. Many homeowners enroll in an annual maintenance agreement so those visits happen on schedule; Aqueduct says most of its installation customers do.

A well-designed, properly installed system should then run quietly for years, watering a Brentwood landscape through hot summers without hoses or guesswork.

Questions Brentwood homeowners ask

Should I install sprinklers before or after sod on a new home?

Ideally plan irrigation before final grading and sod, so pipe sleeves under drives and walks can go in early and the lawn is not disturbed later.

Can a sprinkler system be added to a mature landscape?

Yes. It takes careful routing around tree roots and existing beds, narrow trenching and good restoration, but established yards are retrofitted regularly.

Is a smart controller worth it?

Smart controllers adjust watering for rain, temperature and evapotranspiration. Aqueduct recommends them and says they typically pay for themselves in water savings within a season or two.

Why do sprinkler quotes vary so much?

Zone count, head spacing, drip, controller type, terrain and component grade all change the price. Compare those details, not just the total.

Do I need maintenance after installation?

Yes. Plan for spring activation and fall winterization every year, and consider an annual agreement so the visits happen on schedule.
