The Rock Valley Culligan difference
Great service! Ben, my delivery guy, is awesome! He delivers water and fills the softener with salt every month. He always communicate when he will be there. It is one less thing in my life that I have to worry about so Thank You Rock Valley Culligan!
Nick Villani provided excellent service. He explained the products well and helped me choose the right unit. The installation was quick, Chris and Bryon were professional explaining the water softener well. I would recommend Nick and Culligan to anyone
Purchased a new water softener about a month ago. The salesman came out and was very informative and knew his stuff. The installer was very professional and completed the job quickly. Very informative. Would definitely recommend Rock Valley Culligan for your water softener needs.
