Patterson is ALWAYS great to work with. We have a 100 year old home. Clearly there are no plans for the house and the layout. Joe always takes time to come and figure out where the plumbing lines are and how it works. Because of our old house there are times when he has had to make a couple of trips but he always keeps me up to date and makes sure I understand exactly what he is doing. Should a problem arise Patterson is the only place I call!!
