Glastonbury, Connecticut Customer Reviews

A positive experience from beginning to end!! I received appraisals from 4 separate companies before choosing who I wanted to purchase from…Once I made a final decision, the time frame was exactly as I had been told. The installers were neat, professional, and worked surprisingly quickly removing the old windows and getting the new ones in place. I would HIGHLY recommend Window World to anyone!

We had a kitchen window that was literally rotting off of the house. Anton personally came and installed our new window, and we could not be more pleased! I’m still taken aback every morning when I walk into the kitchen and see the beautiful new window and how much glorious light it lets in!! Thank you, Anton!!

Window World did two replacement casement windows and one patio door. They came on time, were professional and completed their work in a timely manner. Used drop cloths on floors and furniture
