The two men who installed our windows were very professional and did a great job. We have purchased windows from window world in the past. Great windows, and we even used their guarantee on a 10-year-old window. Thanks, guys!

The crew that installed the window were awsome and my new basement window looks amazing. I would recommend Window World to my friends.

Just finished up our house today, and I can’t recommend window world enough!! From start to finish, I’ve been informed, given exactly what they were going to do and the cost. They provided me ahead of time what we needed to have done before their arrival and the install crew was very nice, courteous and respected our house and belongings.
