From the first phone call until the moment they walked out the door, everyone was professional, friendly, and knowledgeable. The only complaint I might have is that it would have been nice to know ahead of time that they had to vent other than at the chimney and that there will be a drainage pipe in a spot that is directly in the path to get to the washer and dryer - its just screaming to be tripped over. However, Adam and Kyle worked their butts off, and the other two men that came later were just as great. Darryl that made the initial visit was so kind to my 90 yr old mom and explained everything very well. I will definitely use Krane again and would recommend to anyone that needs great service.
