What Clients Say
The people are the BEST. They accurately diagnosed why our water was always brown, despite numerous efforts and months working with our previous water softener supplier without success, and they efficiently, professionally, and effectively solved ALL of our water problems in short order. The technician who serviced us was outstanding and explained everything in detail that was easy to understand. The system they installed works flawlessly, and the app that is part of it gives us feedback and alerts the company if any problem occurs, even before we might notice it. I strongly recommend Culligan Rice Lake for any and all of your water problems; they certainly solved all of ours!
