1. Verify the license and insurance yourself
Mississippi regulates plumbing work, and any company doing work that requires permitting should be able to produce its license and certificate of insurance without hesitation. Ask for both in writing. A company that treats the request as unusual is telling you something.
Insurance matters most on the jobs where something can go badly wrong: water line excavation, sewer replacement, gas line work, and anything that opens a wall or a slab.
- Ask for the license number and confirm it is active
- Ask for a certificate of insurance naming the company
- Ask who pulls the permit when a permit is required
