I have had nothing but great experience with their customer service. Great color choices & prices. Quick turn around time as well!

Shortly after I bought my rental property, I realized that I was going to have to replace windows in a three flat apartment. Problem: I needed aluminum windows that where also energy efficient.
Solution: Lang Exterior came to my rescue, and thank God! Their "Ultra Tuff" window line is exactly what I was looking for, and now that I have them I have seen some significant reduction in my heat bills.

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!

The Lang staff did everything they could in order to refuse to comply with the warranty – dragging out any action on their part in order to claim they had no warranty liability.

To date, I have spent over $1,500.00 replacing Lang insulated thermo-pane glass in the windows of my home. Ten Lang “Power Weld Windows” were installed – that means twenty sashes – with twenty sealed insulated glass window panes. Of these twenty insulated, argon filled, glass window panes - the seals on sixteen panes (80%) failed. (Way more than the 1% failure rate of window seals that Lang’ Exterior’s president claims is their normal attrition.)

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!

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!

There were so many choices of colors for our new windows, I'm glad my husband brought me to take a look!!!

These guys make my life so much easier and hassle free. I am happy to work with them, and I do on a regular basis!

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.

It was a pleasure to have these windows installed at my house!

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!

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.
