Avon, Connecticut Customer Reviews

I was very impressed with the whole process. From the sale to installation. Window World’s customer service is fantastic. The installation was done in a day. I couldn’t ask for better performance from AJ and his crew. Milton was very professional and made the install look effortless. Brenda, you are very accommodating as well. Thank you for that.
Tom M.
Right before the 2018 winter season begins our entire house windows were replaced and also patio door. My family and I are happy with the window world from the salesman to the installation crew. Also, Brenda’s professionalism is second to none as well as our installers. Window world Motto “Simply the Best for Less” is a real statement. Highly recommend them.
