"Sal has been our go-to guy ever since we put on a second floor addition twenty years ago here in Palo Alto. He knows what he is doing, makes a point of being up-to-date on all the best systems, is honest, fair, and doesn’t try to sell you anything you don’t need. He has our complete vote of confidence!" – Virginia, Palo Alto
