There was water leaking from the ceiling of my family room. Joe the Plumber's office sent, on 2 separate occasions, 2 young and what we presumed to be, junior, plumbers to my home.
They proceeded to make several holes in my family room ceiling in an effort to trace the leak.
Before taking my entire family room ceiling down, I called them back and asked that they send a more senior plumber on site. They complied with my request and on their 3rd attendance, removed the drywall from my master bath (which is above family room), found the leak, fixed it and repaired my wall.
Overall, they did a great job but only after I requested a more senior member of their staff be sent.
