Jason and Trevor showed up in the first ten minutes of the hour long window I was given for there arrival. They promptly got to work by laying down blankets making sure to protect my floors and they even wrapped a blanket around the legs of a table to ensure their hoses weren’t scratching it. Definitely liked that! They quickly got to work and cleaned up after themselves. They were very professional and quick with there work. I would highly recommend Safety King for anyone looking to get their ducts clean. I was very pleased with there work and professionalism. One happy customer in Rockwood, MI!
