Had a plumbing issue and called to schedule an appointment. With a little bit of background info they were able to tell me how much it would cost to replace my shower valve cartridge ($190). They informed me there could be an extra $100 charge if it is difficult to remove the original cartridge. After it was installed, the plumber, Michael Probst, informed me that it was actually difficult to remove, but not so difficult he would charge me the extra amount. I appreciated his professionalism and honesty. He also did a courtesy check of our water heater, pipe cleanouts, and water quality, etc. Even the plumbing dispatcher, Maria, was courteous and great to work with.
