What We Do

Complete Irrigation,
Start to Finish

Drip irrigation system

Drip Irrigation Install

Precision water delivery directly to root zones. Drip systems use up to 50% less water than traditional sprinklers and eliminate runoff on slopes and planting beds.

Sprinkler system design

Sprinkler System Design

Custom designed zone layouts that match your lawn's shape, sun exposure, and soil type. Every head placed to eliminate dry spots and overlap without waste.

Smart irrigation controller

Smart Controller Upgrade

Replace your old timer with a weather-based smart controller. Your system adjusts automatically based on rainfall and evaporation rates, saving water year round.

Irrigation system inspection

System Inspection

A full head-by-head check of your existing system. We test coverage, look for leaks, identify broken heads, and give you a clear picture of what needs attention.

Irrigation winterization

Winterization

Blow out every zone with compressed air before the freeze. Proper winterization protects your pipes and heads from cracking, saving you hundreds in spring repairs.

Spring irrigation startup

Spring Startup

Turn your system back on the right way. We pressurize gradually, walk every zone, adjust heads and timing, and set your controller for the new season's conditions.

What Customers Say

Real Yards.
Real Savings.

Danny walked our entire yard and designed a system that covers every inch without any dead zones. Our water bill dropped by nearly $60 a month in the summer. The smart controller pays for itself. GreenFlow is the real deal.

Paul and Sandra M. -- Full System Install, Hilliard

We hired GreenFlow to inspect a system that came with the house. Bev found four cracked heads, two zone valve issues, and a slow leak we had no idea about. She fixed everything that day and even reset the controller to a proper schedule. Incredibly thorough.

Meet the Castros

"A well-designed system saves water and keeps everything green."

Danny and Bev Castro launched GreenFlow in 2008 after Danny spent a decade working for a commercial landscaping firm and grew frustrated watching poorly designed irrigation waste thousands of gallons a week. Bev brought her background in horticulture and plant biology to complement Danny's installation expertise.

Today GreenFlow serves residential and commercial clients across the region, maintaining over 400 active seasonal service accounts. The Castros believe that smart irrigation is not just about green lawns, it is about responsible stewardship of water in every yard they touch.
