They will quote you a low ball estimate in order to get the job and the check. They do not perform quality work and you have to call, almost to the point of harrasment, in order for them to finish the job after they get the downpayment. They are your typical contractor is out to make money quick and not realize the consequences that their reputation will do. Please do yourself a favor and find another contractor, one that your friends have told you is good. TAKE IT FROM ME, YOU WILL NOT BE HAPPY YOU WENT WITH ALPINE.
