Lang Exterior
I have a house with all Lang Exterior windows. I just had one slider window that had an issue locking. I called Lang Exterior---these folks were super friendly and responsive, and went out of their way to troubleshoot the issue. They sent someone the very next morning to fix the issue—and he fixed it within minutes! These windows are awesome. They look great, are high-quality, easily slide when unlocked, and are double pane, which gives me a sense of security—and really seals out the noise—which is especially awesome since I live on a corner lot of a really busy street! The former homeowner who chose Lang Exterior windows had really good taste! If I ever bought another property and needed new windows, I would definitely choose Lang Exterior windows. Highest quality windows and they really take care of customers!

After being in the industry for over two decades, I can easily say that I have never found a better price or a better product. Lang consistently produces the best windows, at the best prices, and what's more, they have over 30 some color combinations! I have never had an issue finding a client something that they liked. Plus since the price of Lang windows are where they are, I am able to pass the saving on to home owners. The home owners, then end up spreading the word about my work, and I've gotten more work because of it!

You have to be able to appreciate a locally made product! As a contractor, it's comforting for me to be able to tell my customers that when they spend their money on Lang windows, they are keeping their money in Chicago. Not to mention the fact that Lang has a price guarantee.

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++

I got these windows last winter to replace my single pane windows I had. I knew they were going to make a difference, but I did not think about how nice and updated they would make my home look!

I went to these guys for a window replacement. It was my first stop (recommended by a contractor buddy). I ended up picking out a window, and once it was installed I was in great shape!

I've been doing windows for a long time now. I am surprised at how well the Lang brand has treated me. I save money, my clients save money. It's that simple.

I have had a great relationship with Lang for a couple of years now. I would happily recommend them to anyone looking to get into the window business.
