What Clients Say
I had a terrific experience dealing with John from the Saint John Culligan office. He took the time to explain everything about the purpose of softening the water and what we would expect in our own home. He was extremely patient as our builder was very delayed in finishing our home. He stayed in contact with us throughout the six months we waited for our house. When the house was completed, he was very prompt at hooking up our system so that we would have service immediately. I was very happy with the product purchased but even more importantly, the service we received from John!
