I was told I would get a deal on my windows, and low and behold I shopped around and there was no better price.

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.

A good friend of mine who happens to be a contractor reccomended this company Lang to me when I needed to replace my windows. He told me I could save some money on a nice product. I took his advice and needless to say I am very happy about it.

As a contractor I can speak from experience. Lang windows are a great price, and they have a great line of windows for any project. It was a one stop shop, and I'll be back for my next project. A++

You have to check out these guys if you need new windows! I didn't think that changing my windows could change the look of my house inside and out! So 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.

I love these new windows! They look great and are easy to maintain.

Couldn't have had a more pleasent experience! Fantastic prices, and the service was above and beyond. The knowlegable staff told me about Silence is Golden windows, which really helped reduce the sound of traffic coming through my windows.

Before I bought my patio doors from Lang Exterior I would get ice coming through my old aluminum patio doors. Now I have cherry interior patio doors and never have any ice problems. Thanks to Lang Exterior's windows my furnace doesn't run as often in the winter and I can enjoy fresh air in the spring without the opening bar falling off my old window.

For such a big job like replacing the windows on my home, my contractor was right! I just upgraded big time, and the investment is paying off right in front of my eyes! We love our new windows. The woodgrain colored interior is a great match for our style!

Nice windows!!! I am really happy I purchased windows from Lang. The color matched perfectly. The face of my house looks sooooooooo beautiful:)

I love the color choices, i never knew that there were so many. This place has been in buisness for over 58 years. Wow even though they sell only to contractors I dont mind i just went and looked at the products and had my contractor by the windows for me. and I love them. I purchased there newest window called SILENCE IS GOLDEN. Wow what a diffrence how quite my house is I love them just love them!!! and I also like that Lang Exterior had a R-5 window which is one of the most energy efficent windows that can save on heating and cooling bills with a U.20 and they are so pretty to look at. So yes I would recommend these wndows

I have been a customer of Lang Exterior for over 20 years. I love my window supplier. I know that they are wholesale only, so I know that my business is safe ordering from Lang Exterior, becuase they do not sell product to my customers. They have the best possible window on the market today at the best possible price. They do not skimp on quality in order to deliver the best product at the most resonable price.I can always get what I need from them becuase they have so many colors and options to choose from. I love my Lang Windows!

Arrogant Lady behind the front desk.Customer service non existing. Delivered Wrap around nontransparent foil windows. One of four windows I picked up was broken/Damaged. Called immediately to claim this problem and The same arrogant lady Accused me that I'm lying. That I did brake it. She said they are not responsible for this.Be aware of these people. Bunch of arrogant try to be businesswomen. Shame!Service Sucks
