"We couldn't be happier with our new deck! Bob was amazing to work with and his attention to detail and the quality of his work is outstanding."
"Bob did an excellent job with our deck project. He was extremely communicative through out and was competitively priced when compared to the other quotes I received. He listened to what I wanted and delivered exactly that."
"Bob and Bobby did a great job on our balcony deck. They arrived promptly and were very careful bringing in their tools and equipment since they had to go though our unit. They worked hard all day, and ended up finishing the project earlier than anticipated. The new deck looks great. We’re very pleased."
"Bob and Bobby did an AMAZING job on our new deck. Our old one had been an eye sore since we moved in and the built a beautiful deck very quickly. Great communication about the process of the job and updates during the project. Extremely fair price and would highly recommend"
"Bob did an incredible job on our deck. It ended up being a bigger job than we expected, but Bob got it done before the weather turned too cold. He was honest, excellent at communicating, and we love our new deck."
