John Friend arrived well within the time frame and got to work immediately. Before he came into my house he informed me that he would sanitize all surfaces that he touched. He was masked and gloved. He diagnosed the problem and unclogged the drain within a short period of time. He was very friendly throughout his visit. I have been using Bill Howe plumbing for many years and have recommended them to friends. I am always extremely happy with their work and the people that work there..
