What Our Customers Say
What do our customers say about their experience working with us? Take a look at their experience working with Defender Door Company in Chicago, Illinois…
I was extremely impressed with the door that Defender installed for us. We knew we wanted a door with decorative glass and we ended up buying a door with a woodgrain finish. Even though it is a steel door, it looks just like wood and matches the rest of the woodwork in our house. Working with Defender was also hassle-free which really made us love everything about our door. Thanks, Defender!
After meeting with sales people from several different companies we chose Defender to install our bow window. We couldn’t be happier with the end result. Our new bow window has completely transformed our home. The inside of our house feels more spacious and from the outside it looks much classier. Defender was a pleasure to do business with and we have already referred them to friends.
