Can this business work under this registration? Can work while it stays active.

The registration has 269 days left before it expires on Jul 27, 2027. Check that date against your project timeline.

All status codes are explained in Washington Contractor License Statuses Explained.

Checks for Plumbers

  • Plumbing has two layers: the business registers as a contractor, and individual plumbers hold certificates of competency. Ask who will do the work and check their certificate on L&I Verify.
  • Trainees may work only under appropriate supervision; ask who is supervising.
  • Most plumbing beyond simple repairs needs a permit from your local building department.

How to Verify This Contractor

  1. Use the Confirm on L&I Verify button and search registration PIPERMI796NE or UBI 601838017. The status there is the official one.
  2. Check that the name on your bid or contract matches Piper Mechanical Inc exactly (a corporation).
  3. On L&I Verify, look for bond claims, lawsuits and any newer registration.
  4. Ask for a certificate of insurance sent directly by the insurer, and compare it with the Middlesex Insurance Company policy on file.
  5. Check the individual certificate of the person doing the work, not only the business.
