I had the smoothest and most pleasant experience working with Ryan and his team on my backyard deck and second story deck. Ryan helped me map out my vision for the project and GVD completely the job ahead of my expectations. After going through a long and painful home reno with many delays and cost overruns from other trades working with GVD was a breathe of fresh air. Highly recommended!

Ryan is a pleasure to work with: professional, organized and efficient. Based on the deck he and his team built us 2 years ago, we asked him to build our fence this year.
