I contacted several companies for a water softener. I chose Serv-All not only for their product/price but because Corrine was very pleasant and helpful over the phone. She answered all of my questions and concerns and was never pushy or rude (like some others). Once we made our decision, Theo came out that same day and installed our softener. He was very pleasant and gave us tips on preserving the longevity of our system. Thank you Corrine and Theo!
