We had dealt with our previous plumber for 4 years but on our last "big" project we decided to call around for more options. A&A had the best price by over $100. They came at the time they said they would and the work only took a few hours. They replaced most of piping in the spare bathroom. Everything is working great and they got rid of that annoying knocking sound that we used to get when the water was running.
Will definitely be using A&A again.
