 Trustindex verifies that the original source of the review is Google. Josh Hartman and his team were great to work with from start to finish. Communication was clear, expectations were realistic, and the quality of the work really shows. We talked to several contractors to get a bid on roof replacement and another bid on our outdated kitchen which badly needed a remodel. Josh stood out because he was straightforward and took the time to explain options without any pressure. The crew was professional and respectful of the home, and cleaned up each day. Any questions that came up were handled quickly. You can tell there’s a lot of experience behind the work and his suggestions for small upgrades were much appreciated. If you’re looking for someone reliable for remodeling or roofing in the Austin area, I’d absolutely recommend Josh Hartman

 Trustindex verifies that the original source of the review is Google. Allan, Tom and the crew from A.C. 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!

 Trustindex 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.
