Cornerstone did an extensive remodel of my very dated 1970's house in Quail Creek and did a great job. Many hidden problems were encountered but they managed them very well and explained each issue to me fully. Their extensive knowledge of building methods and materials of past decades made them a good choice for an updating job like mine. The house went from dowdy and obsolete to modern and beautiful and it really looks great! Pete LaTrustindex verifies that the original source of the review is Google. Allan and his crew remodeled my Kitchen. Several little things that made my kitchen pop was a built-in coffee bar, drawer for the garbage , a pull out spice rank in the cabinet. Also redesigning the layout , placing the pantry in the corner and microwave and oven on the wall. Also I had all new flooring done in my kitchen, retreat, and half bath. Over all I highly recommend Alan's crew because of master of details and cleanliness.Google rating score: 5.0 of 5, based on 6 reviews
