Giant Siding and Windows – We are a Westchester County-based Roofing Contractor, Window Installer and Siding Installation Company, proudly serving homeowners throughout Westchester NY and Fairfield County CT. Unlike other window installation companies, roofing and siding contractors, at GIANT Siding and Windows, all our teams do is roofing, siding, and windows.

James Hardie

My Grandfather founded GIANT back in 1965

I learned the business from my father, Bob and the most important lesson he taught me was the value of a strong work ethic; to focus on customer service, community and customer relationships and to provide our fellow Westchester County homeowners an exceptional end-product, at an affordable price.

My dad pictured in the middle in the 60’s specialized in Aluminum Siding. In 2016 GIANT was awarded the first James Hardie Presidents Award, and given the Elite Prefered Installer Seal.

We are proud to serve as the only Elite Preferred Installer of James Hardie Fiber Cement Siding in Westchester County.

Here at GIANT, the faces have changed, the times have changed, but we continue to stay on the cutting edge of Siding technology. We use only the best products and work day in and day out to distinguish our brand and build our reputation of excellence.

It was a wonderful experience. I hired Perry over another provided I was also impressed with based, in no small part, on his reviews on Angies. I'm delighted with my choice... Terry K., White Plains
