“

Called the office mid afternoon about water dripping through main floor into basement and customer service representative informed me that someone would be there between 2-5. Just a few minutes after I received a call that they were on their way. Andrew was the plumber and it’s the second time we have had him for repairs. He was able to diagnose where the leak was and gave us options on how to fix. Highly recommend John The Plumber and Andrew who is very knowledgeable and personable.<br><br>Chri
