Bill Hall was the technician. We have always asked for him for all our plumbing concerns. He is always on time. He uses the paper shoe covers to protect the house. He quickly studies and then diagnoses the problem. He educates us - the homeowner- regarding the plumbing concern. He is a good and clear teacher. He answers questions. He recommends the solution necessary to fix the problem - or he suggests options. He clearly states the total costs involved for the service or repair before he starts the required work. He demonstrates the new corrected function to the homeowner.. By always asking for Bill Hall he gets to know our plumbing and its history. He services two households in our family.,
