Plumbing work in Michigan needs a licence from LARA, the Bureau of Construction Codes. A licensed master plumber or a plumbing contractor must be responsible for the work. You can check any licence for free on LARA Verify a License.
Ask how the job is priced before the plumber starts. Some shops charge a flat price per task. Others charge by the hour plus parts. Ask about a trip or diagnostic fee too.
A water heater replacement, a new gas line or a sewer repair often needs a permit from the city or township. The plumber usually pulls it. Ask.
In older homes, ask about the main shutoff valve and the sewer line material. Many homes built before 1980 have clay or cast iron sewer lines.
Get the warranty in writing. Parts and labor often have different terms.
