My sewer backed up just before bedtime, and I was planning to head out of town for a long weekend first thing in the morning. A call to Mr. Drain Plumbing gave me the option of engaging their 24 hour emergency service or waiting till normal business hours the next day. Against my conservative nature, I decided to roll the dice and wait till morning, crossing my fingers that they could respond first thing. I made contact at 07:00pm, technician arrived before 08:00pm, and by 08:30pm the problem was fixed and we were both out the door. Responsiveness, professionalism, and expertise deserve these five stars!
