The neighborhoods around Front Street and Hickory Creek have been here a long time, and so have the oaks and maples shading them. Head east and south and you're in subdivisions that went in over the last twenty years, with young landscaping and open sun. Those are two completely different irrigation problems, and a one-size system serves neither well.
Carefree Systems has worked both sides of Mokena for over three decades. On the older properties, we're usually repairing, rezoning, or replacing systems that were designed before the trees filled in. On the newer ones, we're building from scratch or upgrading what the builder put in.
Mokena's tree canopy is one of the best things about the older sections of town — and one of the hardest things to irrigate around. Roots find sprinkler lines and grow into them. Canopy blocks spray patterns that worked fine ten years ago. Shaded turf needs a fraction of the water the sunny half of the yard does, but it's often sitting on the same zone.
We handle this three ways: rezoning so sun and shade run independently, replacing root-damaged line with routing that gives major roots a wide berth, and swapping fixed spray heads for rotary nozzles or drip where the canopy has closed in. Trenching near established trees gets done carefully — we'd rather hand-dig a section than cut a structural root.
A twenty-year-old sprinkler system usually still works. It just wastes a lot of water doing it. Old mechanical timers don't know it rained. Worn nozzles mist instead of spray. Heads that were level at install have tilted with frost heave and are now watering the driveway.
A retrofit typically means a smart controller that pulls local weather data and skips unnecessary cycles, matched-precipitation nozzles, and head resetting throughout. It's a fraction of the cost of a new system and usually cuts water use noticeably in the first full season.
Spring startup, mid-season adjustments, and fall winterization on a scheduled Mokena route. Blowouts happen before the first hard freeze — we don't wait for the forecast to scare us.
Annual backflow testing is required by state law on irrigation systems. We're licensed to test, certify, and repair RPZ devices, and we submit the results for you.
Lawn aeration and fertilization, pond treatments and fountain service, landscape lighting design and install, and MistAway mosquito misting systems — Hickory Creek and the surrounding wetland areas make Mokena a genuinely buggy town in July, and barrier treatments make a real difference.
