5.0
Twenty-six reviews. Every one of them five stars.
Highly recommend Hols & Co. if you are looking for someone to build your deck. The whole team was excellent to work with. They were professional, respectful and communicative. They were very efficient when they were on site and kept out property clean while they worked. Solid craftmanship and the finished product is exactly what we were envisioning. We would definitely hire this crew again for future projects.
