This was my first experience purchasing new windows for my home. I asked my contractor for a lot of help throughout this process. He is the one that brought me to Lang Exterior. I was able to take a look at their showroom, which I found very helpful. All in all, I don't plan on needing windows for quite a while, but I would definitely recommend these windows to anyone else!

Very happy about the purchase I just made with Lang Exterior. I just finished installing windows for a client of mine, and I have to say that the wood grain finish really made the room look so much better than the way I had found it.

These new windows from Lang Exterior are great. They were affordable, and they are reliable.

Great windows! Great Prices! Great options! All around, I give these guys two thumbs up!

I wasn't looking forward to the process of replacing 4 windows. With the winter coming, and knowing my old windows, my heating bill would have been outrageous if I had not made the move for new windows when I did. I got in touch with a local contractor, and requested the Lang product. He confessed that to his surprise Lang was actually a better deal than his usual supplier! I guess a little research really paid off!

I couldn't be happier with Lang Exterior. I needed to get windows replaced before the cold weather came. A contractor I was working with was able to get me my windows in 10 days!

I went to the location on Pulaski (not the address here) and I placed a small order for a small job to try them out. I will definitely be back on my next big job. I don't usually write reviews, but I have had trouble finding a good window distributor before I found Lang.

Went into your store a few weeks ago, and got a quote pretty quickly. Took that quote to client, and they couldn't believe how low my price was for them. thanks

Two thumbs up to these guys! Can't believe they are able to price their product as well as they do! If you want nice windows at an amazing price, these are your guys.

I've dealt with a few different window manufacturers and dealers in the Chicago area, by far this was one of the best experiences I have had yet. I saved a bunch of money, and got to pass the savings on to my client who was extremely happy.

I love love LOVE our new windows from Lang Exterior! My husband and I had a hard time deciding between all the different color choices but we picked brown on the outside and cherry woodgrain on the inside and they are beautiful!!! The wood looks so real, I can't believe it's vinyl! I would use Lang windows again in a heartbeat and I would recommend them to anyone!

Good quality, and low prices. Quite a value in that they have a everyday window which is better than average, and a Sunday kind of window that exceeds most of the competition's spec's. I use them almost exclusively.
