Irrigation & Sprinkler Systems Tuned for Real Lawns

A typical quarter-acre Lake Norman lot runs $3,200 to $5,500 for a complete system. Systems are priced by zone, not by lot size, and most quarter-acre properties need four to six zones. A zone is a group of heads that can run together without starving each other of pressure, and how many you need is decided by your water pressure and flow rate, not by your budget.

That is why we measure pressure and flow at the spigot before quoting. A house on a well behaves very differently from one on Mooresville or Statesville municipal water, and a system designed for the wrong number waters unevenly no matter how good the parts are. Adding a smart controller is $180 to $400 and is the one upgrade that pays for itself; adding drip lines for beds is $400 to $900.

• Rotors for open turf. They throw 25 to 45 feet and suit front and back lawns. Fewer heads, fewer trenches, lower cost per square foot.
• Sprays for tight areas. Strips along a driveway or between beds need short, controlled throw. More heads, more cost, less waste on the sidewalk.
• Drip for beds and foundations. Water goes to the root instead of the leaf. Uses far less, and keeps water off siding and mulch.
• Backflow preventer. Not optional and not a place to save. It is what keeps irrigation water out of your drinking water, and it is code.

Lines are pulled or trenched eight to twelve inches down, below the depth a core aerator or a shovel will reach. Every zone is pressure-tested and every head is set and adjusted before anything is backfilled, because finding a weeping fitting after the sod is back down means digging the same trench twice.

Heads are set flush with finished grade so a mower passes over them, and spaced head-to-head, meaning each head throws far enough to reach the next one. That overlap looks like waste on paper and is exactly what prevents the dry rings and brown arcs that show up in July on a system spaced to save on parts.

A standard install on a quarter-acre lot takes two to three days. We call NC 811 before the first trench, every time, at no cost to you.

North Carolina freezes hard enough to split a pipe, and it does it on a schedule that catches people out. Water left in a lateral line expands when it freezes, and the crack does not show until you turn the system on in April and watch a section of yard turn into a spring. Schedule the blow-out before the first hard freeze, generally mid-November in Iredell.

A blow-out runs compressed air through each zone until the lines are clear, and takes under an hour on most systems. A single split lateral typically costs $200 to $600 to locate and repair, and a cracked backflow preventer more than that. It is the cheapest maintenance item on any property that has irrigation.

A clock-based timer waters on Tuesday whether or not it rained on Monday. A weather-based controller pulls local data and skips or shortens the cycle, which in this area usually means noticeably lower summer bills and, more importantly, a lawn that is not drowning. Overwatering causes more of the fungus and shallow-root problems we get called about than underwatering does.

We also set the schedule to water early morning rather than evening. Evening watering leaves grass blades wet overnight, which is how brown patch takes hold in fescue during a humid Carolina summer. If your system currently runs at 8pm, that is worth changing today and costs nothing.
