Los Altos plumber. ★★★★★
I found this company in my Los Altos Yellow Pages. They checked out my hot water heater which was very noisy and recommended we change it. I never thought about buying a larger capacity water heater for our home until the plumber had mentioned it. So not only do I have a new heater but also more hot water. Now the family will be happy :)

Reliable and professional service. ★★★★★
My family and 
I just moved in, my mother was alarmed when the kitchen sink wasn't draining properly. The owner of Comet Plumbing came quickly to check the plumbing under the sink which I knew was old.

Andrew unblocked the clog and installed new pipework beneath the sink. I am very grateful,it was only $99.00 for this great service.
