Precision Irrigation for Chicagoland Lawns

Raintree Irrigation has been designing and servicing irrigation systems across Naperville and DuPage County since 1975. We build systems to the exact specifications your lawn needs — calibrated pressure, designed zones, and no over-watering.

Every installation is Illinois plumbing-code compliant and engineered to match your soil type, sun exposure, and plant material. We don’t upsell hardware you don’t need.

Spring Startup & Tune-Up

Spring sprinkler startup in progress

Each spring, your irrigation system needs a careful startup before the season begins:

  • Backflow preventer inspection and certification
  • Zone-by-zone head check and adjustment
  • Controller programming review for current season
  • Leak and breakage inspection before full pressure is applied

We schedule spring startups throughout April and May. Early booking fills fast — call or book online now.

Fall Winterization (Blow-Out)

Fall irrigation blow-out / winterization

Illinois winters will crack your manifolds and heads if your system isn’t properly drained. Our compressed-air blow-out service:

  • Clears all water from every zone and lateral line
  • Protects backflow preventers and manifold assemblies
  • Documents which zones were cleared for spring reference
  • Usually completes in under an hour for residential systems

We blow out systems from late September through November. Don’t wait until a freeze warning — schedule early.

Smart Wi-Fi Controller Upgrades

Upgrade from a basic timer to a weather-based smart controller:

  • Rachio, Orbit B-hyve, and Hunter Hydrawise installations available
  • Auto-adjusts watering based on local weather and evapotranspiration data
  • Control from your phone, set seasonal schedules, get leak alerts
  • Saves 20–50% on water bills versus fixed-timer schedules

Repairs & System Expansions

We service all makes and models of residential and commercial irrigation systems:

  • Broken or sunken heads replaced same-day in most cases
  • Zone valve and solenoid replacements
  • Manifold and mainline repairs
  • Zone additions and layout redesigns for landscaping changes
