  • Broken head, valve and line repairs
  • Controller programming
  • Fall winterization (compressor blowout)

Designed in zones

A good system waters lawn and beds differently, and sun and shade differently. We split the property into zones so each area gets what it needs: rotors for open lawn, spray heads for tight areas, and drip lines for shrubs and flower beds. Matching the heads in each zone keeps coverage even, so you don't get brown corners and soggy spots.

Watering smart on Long Island

Long Island's sandy soil drains quickly, and summer demand puts real strain on the water supply. If you're on Suffolk County Water Authority water, irrigation runs on an odd/even schedule (odd-numbered addresses on odd days, even on even days) and not between 10 a.m. and 4 p.m. We program your controller to follow those rules, water early in the morning in shorter cycles the soil can absorb, and we can add a rain sensor so the system skips a cycle after a storm.

Start-ups and winterization

Every spring we turn the water back on, check each zone, fix and adjust heads, and program the controller. Every fall, before the first hard freeze, we blow the lines out with a compressor so water left in the pipes doesn't freeze and crack them. Skipping winterization is the most common reason for spring repair bills.
