Many people use the terms plumber and plumbing contractor interchangeably. While they are closely related, they are not always the same. Understanding the difference can help you choose the right professional for a repair, renovation, construction project, or commercial plumbing job.

For most everyday plumbing issues, a licensed plumber is the right person to call.
