We specialize in designing, installing and maintaining residential and commercial lawn sprinkler systems.  We have also received our  Certified Irrigation Contractors license from the Irrigation Association and are partners with the EPA WaterSense program.

We have installed thousands of systems in our 39 years in the business in communities such as New Lenox, Mokena, Homer Glen, Frankfort, Lockport, Lemont, Naperville, Shorewood, Plainfield, Manhattan, Matteson, Tinley Park and Orland Park as well as most of the Chicagoand area. We have never had an underground pipe break from freezing.  Our systems are the best quality and easiest systems to winterize available today. We back up our self-draining systems with a lifetime warranty against freeze damage on all of the poly piping.
