Excellent experience with DiMarco plumbing! We had a water leak from an upstairs bathroom that leaked into a room downstairs. They were able to get to me same day to diagnose the source of the leak. Super friendly and knowledgeable; while no one ever wants to ‘have’ to call a plumber, this is the only company I will call from now on. Highly recommended!
