Z PLUMBERZ of Ann Arbor was perfect for my job. They were very good. They were courteous and thoughtful. They were mindful that my house is in an old historic district and doesn't have a high ceiling, so the work was hard. Working under those conditions, they did a good job switching out galvanized plumbing. Work is never easy in an old house and unexpected things happen, but they were confident. I would call them again. I've already used them a couple of times. I was so grateful that one morning I brought a homemade breakfast casserole to them at their office.
