Hear It Straight from Our Happy Customers

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. 



– Marcia Herman
