  2. 2. Diagnose or plan – test first, then propose the right fix or scope
  3. 3. Provide clear options – scope, timing, and what’s included
  4. 4. Execute professionally – neat installs, code-compliant work, minimal disruption
  5. 5. Verify + label – testing, final walkthrough, and clear panel schedules
