Vitaly and his team were very responsive when I called on a Saturday to inspect my basement drain. The water level of the catch appeared higher than normal and I wanted to make sure there was no blockage causing a back-up. Vitaly answered the phone personally and assured me that he would come by that evening. He was courteous at the door, removing his outdoor footwear. He performed a thorough inspection using his camera equipment, and explained to me exactly what was showing on the monitor. Although thankfully there was no problem to fix this time around, I wound not hesitate to call Master Drain & Water Works again in the future.
