Irrigation Services

Irrigation Services in Woodbury, Rosemount & Stillwater, MN, and Hudson, WI

Complete irrigation system installation, repairs, maintenance, and seasonal services for residential and commercial properties

A Minnesota winter doesn’t forgive a poorly winterized irrigation system. One hard freeze with water still in the lines means burst pipes, cracked backflow preventers, and a repair bill before the season even starts. On the other end, an undersized or poorly zoned system means dry spots in August when turf stress is already high and recovery is slow.

LNG’s irrigation team handles the full seasonal cycle, spring startups in April and May, system design and installation for new builds and renovations, and winterization from September through the first hard freeze. Winterization isn’t just blowing out the lines, it’s closing the backflow device, turning valves to 45 degrees to prevent cracking, shutting down the controller properly, and protecting every above-ground component before temperatures drop.

New system installations include drip irrigation for beds, full sprinkler systems zoned for turf and plantings, and Wi-Fi smart controllers (Toro). Target watering runs 1–1.5″ per week delivered between 4–10am to minimize evaporation and disease pressure. Backflow testing is available year-round for commercial properties and seasonally for residential.
