Here's What Some of Our Clients Have to Say

"Their attention to detail was amazing and it showed in the execution. After speaking with multiple companies, getting multiple estimates, asking neighbors for recommendations, and even James Hardie for certified vendors I am truly satisfied with my decision and the work that Giant completed for us. I am happy I chose Giant Siding & Windows and would HIGHLY recommend them to you."

"We used Giant for residing of our house. Their quote was HALF of what another local competition came in at. The team showed up promptly at 8:00 am each day and worked hard all day long till quitting time at 6pm...The team was very friendly and true masters of their craft!!! The outcome was way past our expectations! Our roof needs replacing and Giant will start next week as well as build a new deck for us! We HIGHLY recommend Giant."

"I was most satisfied with how professional they were. The owner even went with me to present to the historic board. Also, they had to redo some work that another contractor had done and did it very well and without fuss. They also were very nice to my neighbors who are very particular. I would like to recognize the owner, for his exceptional service. As well as Tony, the foreman. He was excellent, and all the men that worked under him were very professional."
