Very fast and helpful service technician. He had my drain cleared in about 45 mins. He was friendly, clean, and followed the appropriate safety precautions for Covid-19. The service itself ... is a bit expensive in my opinion, but you can’t argue with the results. I appreciated the ease of scheduling the appointment, the fast follow up, the small appointment window (2 hours as opposed to waiting half the day is really nice), and the punctuality of the technician. He came within 30 mins of the phone call as promised. My only suggested improvement would be to provide a baseline quote when the appointment is scheduled. For example, a standard drain cleaning starts at $X and may increase with additional time and complications.
