I was recommended to come to Lang exterior. From the moment I walked in I was treated by a very friendly staff. I got immediate service. My screen was repaired within an hour at a very reasonable price. They also have a show room of beautiful windows to look at 2323 W 59th St, Chicago. I highly recommend Lang Exterior for any window needs. read more

Quick, no hassle service. Dropped my broken double pane window off at 9am. It was ready the same afternoon. Will definitely use again!

I would like a owner or supervisor to contact me to resolve a issue, before i write my review.

Thank you to Amy and staff for treating me like my problem mattered (broken double pane glass window to child's bedroom). Lang is exceptional because of their commitment to customer service and same day glass repair guarantee: must be brought in before 9AM. In my particular situation, since I didn't bring the window in before 9, they could not guarantee that my window would be fixed that day; however, due to my situation, the staff pulled off a small miracle of sorts and I was told to pick it up by 3PM that same afternoon. I am very grateful to Lang for their professionalism, quality of work and the price of the repair. From now on, Lang will be our first choice for all of my future home window needs. read more

Beth and the entire staff at Lang are extremely helpful and kind. I trust the product and feel confident about them standing by their work.

In 2004, we replaced all 17 windows of our house with Lang Exterior series 1600. They have been great windows. The only problem has been deterioration and separation of the weather strip on the bottom of the lower sash. I brought pictures of the drooping weatherstrip to the store and they provided replacement weatherstrip at no charge. It is not hard to replace. After 16 years, I am glad we went with Lang. read more

Lang Exterior has become my #1 go-to for windows based upon quality. The product is outstanding (visually and functionally). Ordering was also a smooth process, and my shipment was timely. read more

A-1 door replacement!! I wanted to match existing sliding screen doors on the front a 3 unit building. Lang not only got the sizing perfect, but the also we're dead on with the color! Quick turnaround as well! These screens actually make the doors look better! read more

I had lang exterior windows installed nine years ago and the bubble seal on the south and east windows had deteriorated due to the extensive exposure to the sun. I brought the windows to Lang windows on 59th st. today and they replaced the seals at no charge after 9 years. while I was there I was helped by their extremely courteous office personnel, 2 ladies and one young gentleman. I was treated with great respect and they were extremely helpful in helping me to solve my problem. I highly recommend this company to anyone who is looking to replace windows in their home. I give them a 5 star rating.. read more

I just moved into a house that has fairly new (2007) all Lang Exterior windows. All the windows have a good quality look and operate perfectly, except for just one slider window that had an issue locking. I was concerned about it, especially with a string of burglaries going on around the area I live in. I called Lang Exterior, and was pleasantly surprised how responsive they were. I spoke to Sue and Mike. These folks were super friendly and went out of their way to troubleshoot the issue and help me. They sent Darius 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! read more

I have a lot of experience and have found no better windows for the price! Their team of girls in the office get orders processed faster than Jiminy Cricket. Even if Lang didn't provide a superior product, I'd still want to deal with them because they are so nice and professional. Fortunately, though, there isn't another provider who can compete with their quality of product and pricing. Order with confidence! read more

Lang Windows are one of the best vinyl Windows in the business, if not the best that I have ever installed. Would highly recommend them.

Another pleased customer. Thank you Lang Exterior. My end customer was very happy with the quality and look of their new windows. Your customer service is very helpful in advising the right product for my customer. I definitely will be using you again. Cost effective and quality you can't beat!! read more

In 2013 we gut rehabbed our home. Everything down to the windows needed replacement. Lang was recommended to us by our contractor. We had every single window and sliding door in our town house custom measured and ordered from Lang. From start to finish they have been accommodating. We had to choose an exterior color to match the rest of the windows on our town home group. They provided me with vinyl sampled to take home. The windows are efficient and high quality and we are very happy with them. Fast forward to 2017 - our contractor (who installed the doors) did not install the latch for the screen doors. One call and Beth, who is at the 59th St location was able to help me almost immediately! I emailed her a copy of the invoice and she was able to locate and send the parts we needed the very next day. Customer service at both the Pulaski and 59th St locations has been top notch. I highly recommend Lang! read more

In the surrounding area I was at work with, Lang Exterior repaired a window for me at a low cost and also at my convenience. Very cost effective business and also a friendly customer service which was appealing! Thank you for your business, I will continue to be a partner! read more

Yes I waited a few years to write the review because I just learned about Yelp. Very few people insulted me as bad as the old Mr Lang. He treated people like dirt. You (the daughter) can try to give excuses, any window contractors in the area know how rude Mr Lang is. That's the truth. read more

I have never encountered worst customer service anywhere. They failed to charge me the final payment prior to shipping the windows. When they did contact me I told them I was out of town and would get them the authorization upon my return. They charged my account without the authorization, and 4 days earlier than we agreed. When I called to express my frustration the owner/office manager accused me of lying and of stealing windows. I agree with the other review. These people are insulting. They are rude, disorganized, and dishonest. Avoid them. read more
