Our kitchen sink would never completely drain so I called and made an appointment. I got an appointment the next day to have the issue diagnosed. The problem was diagnosed quickly and resolved quickly as well. Very impressed with the whole process and would recommend to anyone to use them. Also, very reasonably priced!
