Customer service was impeccable . The representatives were extremely helpful with making the necessary changes to my order.
I Recently remodeled my home and used Lang windows. I purchased their black vinyl windows and am extremely satisfied with how they came out. The exterior of the window is black and interior is white. Pricing was also cheaper than its competitors. I highly recommend Lang Windows!
I am a developer in the Chicago and have used Lang for my last 2 projects. I am extremely satisfied with the quality of the windows and sliding patio doors. Customer service with Theresa at their Pulaski location is great. Highly recommended!
Nowadays good customer service is hard to come by. However, Beth at Lang Exterior goes above and beyond every time my company needs something. Thanks Beth!
We had 15 Lang Windows put in 4 years ago. We are so happy with these windows! We had terrible windows in this house when we moved in, and replaced them all with Lang Windows. Our heating bill went way down the first winter we had them, and has stayed that way. I just called the customer service number, and was treated with such kindness! So happy with our Lang Windows! Would highly recommend Lang Windows to anyone thinking of replacing theirs!
Definitely!! happy with my decision to purchase Lang windows and patio doors. Absolutely love my doors & windows and the customer service is outstanding!!
Lang exterior has excellent service, and great quality!
This is a business that knows there doors and windows and treats you with respect. I will always purchase from them
Great window company with reliable service. I worked with Lang Northside for over 20 years and I would recommend strongly.
I was recommended to come to lang exterior. From the moment I walked in the personal was kind and inviting. I was taken care of immediately, and I got same day service. My screen was repaired within a hour, at a very reasonable price. I highly recommend Lang exterior for your screen repair. And they have beautiful sample windows to look at in their show room on 2323 W 59th St, Chicago. Thank you again to the customer service department.
Year after year Lang exterior continues to impress me with their dedication to customer service and their perpetual drive towards perfection. Simply said, they have the best window on the market.
We purchased 4 front windows and I love the windows. I was skeptical on what I ordered but I love them. They are exactly what I wanted.
My wife and I had a contractor rehab our house and they installed 13 Lang vinyl windows. They were really nice black exterior and white interior vinyl windows. We were having problems with a couple windows not operating properly, and I emailed Lang customer service. The next day I received a call the next day by David who was genuinely concerned with the problems we were having. He requested a few pics and a short video so he could see what was going on. With the little information he had, he was able to troubleshoot this problem, get me the replacement springs and tool to adjust. We appreciate the fantastic customer service, as this was a problem caused by poor installation of our contractor. The windows are beautiful, and operate great again. We highly recommend Lang windows! Thank you David for the fantastic customer service, we greatly appreciate it! Brian & Teresa
Called about degraded weather stripping(bulb seal) on at least 15 year old windows. I was told I could pick some up at one of their locations. I asked if it could be shipped as I am located out of the state. NO PROBLEM. Jan took all my info and actually walked me through fixing an issue with a window latch I thought I'd messed up. I received the bulb seal early the next day, called when I had a question about installation, the gentleman, I didn't get his name, walked me through it. GREAT CUSTOMER service.
Great people to do business with polite precise and great prices
Ordered all triple pane argon filled windows for my new construction and they are outstanding. The house stays warm in winter and cool in summer. They are very well insulated and look great.
Top shelf service, the supreme workmanship is outstanding.This is my second time back for more work on other windows. they have gain my trust.
We dropped off windows at Lang Exterior Windows and Aimee was great! She took great care of us. All the staff seemed very professional and very helpful. Same day service, definitely recommend.
This company has by far the best customer service! I have worked with them on several occasions and they have never failed me once. I cannot thank them enough for always coming through.

I had an amazing experience with this company. The windows look amazing and came in time for all the beautiful photos we took for my son's wedding! We chose to pay more for black windows and they are awesome! It transformed our 44 year old home into the modern century!
I just visited Lang Exterior Windows and my experience there was as it has been each time: as warm as a shut window on a cold wintry night, and as easy as an open window on a breezy spring day--pleasant. Thank you so very much for your product and your experience.
This 4 lite Patio door is the bomb! I feel like I live in Florida! Thank you for such a great product!

Great experience with Lang. Great pricing and product. Delivery on time. Would recommend to everyone.
I had a weather strip replacement requirement on two windows on my north facing elevation. Lang was happy to replace under warrantee the seals. This goes above and beyond all expectations. I would recommend Lang for your future window needs.
Outstanding! We had to have a few windows replaced after they were damaged. We were frustrated until we contacted Lang Exteriors. Their customer service was second to none. They were efficient, knowledgeable, and a pleasure to deal with. Their products are superior and I would recommend them in a heartbeat.
We had Lang Exterior windows installed a few weeks ago and the house is so much quieter. Now every window can open and close so smoothly. We are very happy with the new Lang windows. I cannot recommend them enough. Can't wait for a warmer winter indoors this year. No more drafts and leaks. These are great.
We went with platinum 2400 for the the thicker frame little more money well worth the cost . Very solid and nice windows . I will recommend Lang Windows to all who are looking for new windows. Lang is the best !
Far superior to the windows available at the big box home centers. Spiral tensioner NOT a piece of string. Re-enforced top and bottom; optional foam insulation, etc. make these windows outstanding.
Great product here at Lang been a long time customer and the showroom was a great idea!
As a homeowner the knowledge and helpful attitude of the staff at Lang made a complicated task of ordering our windows a very positive experience.f Thank-you.

Lang has unbeatable pricing on a high quality product! I can't say enough how happy I am to work with Lang!
Wonderful windows made a huge diference in our heat and cooling bills. They operate smoothly and close tight. The service on a small item(night lock that we broke) was wonderful. we would recommend Lang windows to anyone.
As a contractor, I'd just like to thank you for all of the help you have provided for my business. You have proven to be a name I can trust, and a name I believe in.
I can't tell you how nice my new windows look... I love them. Thank you for making such a great product!
These windows are awesome! Thank you for making such a great product!
when my contractor showed me all of the color choice that Lang Exterior had to offer i couldnt belive that they exsisted. I love how rich the woodgrains look and also i love all of the attention to detail that is in the window it looks like wood to me i couldnt get over how rich the window looked in person. I love Lang Vinyl windows.
I used Power Weld windows in the homes I was renovating. The windows look good, nice curb appeal, work well, and kept square during installation. After five years they perform as well as they were new. Now as I res erect the A****** Lang is going to be a vital part of my product offerings.
I am a first time homeowner and I just had all of my old windows replaced with Lang windows. I could not have made a better choice. I did some shopping around and the Lang windows I bought were both very well made and affordable. I look forward to using them again in the future and would recommend them to anyone.
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.
