I am a contractor that uses Malcolm Plumbing & Mechanical all of the time. I call them out on jobs for my commercial customers, as well as my personal residence. Recently, I did have them handle a couple of projects for me. The technicians came out to handle a backflow device. The technicians that the company sends out are always very nice to work with, highly knowledgeable and very professional. I have always recommended Malcolm Plumbing & Mechanical to others and plan to continue using them regularly.
