I had an great experience working with Heiner and his team when it came to our bathroom renovation. From start to finish, they were professional, detail-oriented, and delivered exactly what I wanted. The entire process was smooth, and exceeded my expectations.
We needed to update our living room and hired Cornerstone Building Group based on a friend’s recommendation. Heiner and his team did such a great job—they were easy to work with, showed up on time, and paid attention to the smallest details. The space looks amazing now, and the whole family loves it. Would definitely work with them again!

We hired Cornerstone Building Group to update our living room, and it turned out better than we imagined. The team was professional, showed up on time every day, and cleaned up before they left. Heiner was great about explaining everything and making sure we were happy with each step. It was such a smooth process, and now our space feels brand new.

I recently had Cornerstone Building Group renovate my bathroom, and I couldn’t be happier with the results. Heiner and his team were friendly and easy to work with, and they made sure to keep me updated throughout the process. They even finished a little earlier than expected! My bathroom looks amazing now, and I’ve already recommended them to a couple of friends.
