Alpine gave me a very competitive quote relative to their major competitor last year and stuck by it this year when I finally got the permit to complete the job. They were on site within a couple of days and finished the job in a day, cheerfully and adding small additions at my request. I really liked the supportive attitudes of Mimi, William, and the crew on site besides the quality and promptness of the work.
I thought that Mimi summed up the company succinctly when he told me that they try to be 'fair' in their pricing, including the extras. I think that this is a far better approach than cheap or simply competitive.
