This is the very best and most professional plumbing service by far.  I have used many companies but Malcolm is the best.  I always feel like they are taking care of me and that they really care.

– Joanne Weir

I called Malcolm Plumbing as I wanted a gas pipe with a shut off and on valve, in a 100+ year old fireplace that is no longer safe to use, removed. I realized that I had 2 other fireplaces in the building with the same concern.

     Max shut off the gas, removed and capped all 3 valves and then thought to go into the optometry business on the ground floor and relight the pilot on the water heater for the whole building.  Max was thoughtful about safety, very timely, efficient and I highly recommend him and Malcolm Plumbing.
