"I highly recommend NW Sundance. Setting up the appointment was easy, they called 30 minutes before they showed up to let me know they were coming like promised, arrived on time, and quoted me the repair price all in a very effortless matter.The plumber Jorge was a great guy. Very professional, outgoing and efficient. He even cleaned up his mess when he was done, not leaving a trace behind that he was even there, except for new pipes and the garbage disposal he just installed for me. Even disposed of the old unit for me, without even asking. I am very impressed with these guys and will use them again if the need arises."
