Malcolm Plumbing & Mechanical is a great company, and I often recommend them to others! I am a frequent user thanks to a rental home I manage, which was built in the early 1900s in San Fransisco. I originally had them working at my own home, and they did such great work, I had them start working on the rental home as well. They're always available when I need them, which is great since a lot of the issues from that old home are emergency situations. This last time I used them for the rental, it was due to a clogged drain, and everything went well. They were neat and tidy, per usual, and they always perform thorough checks to make sure the work was done correctly. We just love them and will continue using their services!
