Improving NY & CT Homes For 3 Generations
5-Star Customer Service for Over 60 Years!
Serving Westchester & Fairfield Homeowners with Fairness, Honesty, and Integrity.
At GIANT Siding and Windows, we’re a family-owned exterior remodeling company proudly serving Westchester County, NY, and Fairfield County, CT since 1965. Founded by my grandfather and passed down through generations, GIANT has always stood for integrity, craftsmanship, and community. I learned the business from my father, Bob, who taught me the importance of a strong work ethic and treating every homeowner like a neighbor.
Unlike other contractors, we focus exclusively on what we do best—roofing, siding, and windows. Our dedicated teams deliver exceptional results with personalized service and affordable pricing—because that's what our New York & Connecticut neighbors deserve.
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."
Steven G.
"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."
Peter W.
"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."

The Values That Shape Every Project
Our values are rooted in tradition, craftsmanship, and a commitment to excellence. From my father’s early days specializing in aluminum siding to becoming the only Elite Preferred Installer of James Hardie® siding in Westchester County, we've built our reputation by staying on the cutting edge of siding, roofing, and window technology. We pair industry-leading products—like James Hardie®, GAF®, and Marvin Integrity®—with factory-trained experts who take pride in precision, efficiency, and care.
Every project we take on reflects our promise: deliver an exceptional product that lasts a lifetime. I personally stand behind our work, sharing my direct phone number with every client, because I believe in what we do and who we are. With the best tools, the best training, and the best people, we create results few can rival.
