Dependable Swimming Pool Service, Inc. is a family owned and operated business. We have been serving the Grayslake, IL and Lake County area since 1969. We have grown from a maintenance company operating out of a one-car garage to a 2,200 square foot retail showroom. Besides providing pool maintenance, we carry BioGuard pool chemicals, SpaGuard spa chemicals, and Doughboy above ground swimming pools. We also carry a full line of pool and spa accessories, pool toys, ladders, pool heaters or just about anything else you may need for your pool or spa.
