Mike and his apprentice have done a handful of jobs for our new home (built in the 50's) and have always been honest, extremely personable, and outrageously helpful with anything and everything. When contacting a plumber, 99% of the time, you're in a frantic state and seeking immediate help. In those times, I'm so glad that I can reach out to KO knowing they're going to give quality feedback and not rush anything. Mike is truly a standup guy and you can definitely see that in his apprentice as well. They will listen to you without making you feel like an idiot :)
