See Why Brooklyn Residents Love Window World

Had my bay window replaced with a beautiful bow window by Window World and they did an excellent job. They did a quick job; it only took 3 hours to do. They cleaned up nicely afterward, they were polite. Just overall great! Highly recommended!

I recently had new windows installed by Window World of Long Island and I couldn’t be more impressed with the entire experience. From start to finish, they exceeded my expectations with their professionalism and attention to detail.

Window World of Long Island renovated the entire exterior of our 70-year-old house. New roof, new siding, new doors, new windows. It was without a doubt the best experience we have ever had with a contractor. On time, under budget, polite and courteous people, and absolutely top-shelf quality workmanship. We couldn’t be happier with our decision to use Window World of Long Island.
