About

Your Crystal Lake Water Treatment Experts. We are Culligan of Crystal Lake, your water technology experts proudly serving in Northeast Illinois. Our dealership specializes in providing water softeners, reverse osmosis systems, water coolers, bottled water, water filtering and softener salt delivery service to area homes and businesses. For over 70 years, Culligan's mission has been to deliver high-quality water treatment products that will benefit every part of our customers' lives. We hope to raise the quality of life by purifying its most essential element: water. Hard water is the biggest problem in Crystal Lake, but high TDS, iron water and sulfur water are also concerns for local residents. Water that tastes like rocks and smells like iron or rotten eggs are signs of these Crystal Lake water problems, in addition to spotty dishes, white build-up on fixtures and red stains on sinks and tubs. Water problems can harm your home or business in a variety of ways, and Culligan has the right water treatment equipment for every situation.
