We have used Malcolm Plumbing & Mechanical multiple times. Someone else calls to schedule them, but I'm the one who gave them access for their most recent visit. They showed up within the window that they said they would, took care of the job, and checked out with me. I didn't hear any complaints and we never have any issues with their work. I've already referred Malcolm Plumbing & Mechanical to other customers. I recommend them to you. Five stars!
