 Trustindex verifies that the original source of the review is Google. 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! Ethan in Leslieville

 Trustindex verifies that the original source of the review is Google. 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. Quality craftsmanship on both projects shows how much care and pride are involved. I would highly recommend working with GVD: great work and great people!

Last year, Ryan built a fantastic deck for my current home, and it’s been everything I hoped for—sturdy, beautifully designed, and perfect for enjoying time outdoors. They also did the deck at previous home, my parents’ place, and even a few friends, and every single project has been top-notch.Ryan is professional, reliable, and really listens to what you want, making sure the end result fits your vision. Their consistency across all these jobs speaks volumes about their skill and dedication. If you’re looking for a deck builder you can trust, Golden Valley Decks is the way to go—I’d recommend them to anyone!

 Trustindex verifies that the original source of the review is Google. I was referred to Ryan by a friend. Ryan and his team built our first composite deck. I was very happy with the quality of work done and they completed the work in the time we requested. My kids enjoyed their activities on the deck all summer long. Looking forward to spending more summers on the deck with the kids. We would highly recommend Golden Valley Decks.
