After having such a stressful experience with another company, I was so glad to see that the guys at Sterling Windows and doors still had a thing called Pride in their work.These guys were very professional throughout the whole job. They even cleaned up after themselves.If you want stress free craftsmanship with a strong sense of Pride, then the guys at Sterling are who you want. They transformed my 84 year old home into something of the modern day. They sealed up all my drafts that were letting heat and air escape. My climate control system nolonger runs constantly. Cant wait to see my electric bill lol Cant even hear traffic outside. So comfortable and tight now. Absolutely wonderful.Once again, thank you so much for your hard work...

We worked with Sterling directly. Our installation was in 1995 and they were Amazing. Sterling is knowledgeable, informative, patient and oversaw the work. Our windows have been in for 26 years and are exceptional. We had a broken pane about 2 or 3 years ago, and Sterling had it replaced same day! We just recently noticed they now have triple pane and are reaching back out to Sterling to check out available options. He and his crew were FABULOUS and are committed to excellence. We would highly recommend Sterling Windows!

From scheduling a consultation to installation, the process was as quick and easy as it should be. David showed up as scheduled and gave me a very reasonable quote to replace an existing sliding door. We ordered the door and expected to wait 6-10 weeks for arrival. About 5 weeks later, I got a phonecall to schedule the install. Jerry and Tim did a phenomenal job putting the door in and making it seem like its been there all along. I could not be happier with my new door!

I purchased 12 windows from Sterling February 2020. We went with the black frames on the outside. The windows look great. David Lance has a real passion for making the customer happy. One of my windows had a crack from the factory and they replaced it with no questions asked. I can not remember the name of the guy that comes to your house for repairs, but he is the same way. He answered all my questions and provided updates throughout the repair.

If you need new windows, Sterling Windows is where its at!! I had 4 companies come out and they were not only the best priced but they are local and I just had a good feeling. Yes I had to wait from Dec to now (March) to get them but thats how busy they are. And they make all their stuff right here in Knoxville! Which also means, you dont pay taxes because you are buying straight from the manufacturer! The guys came out, undid all my blinds, moved the furniture, and even took down the unsightly window molding I was planning on taking down anyway and cleaned up after themselves like they were never here. And before you ask...I dont work for them. Haha. But I will always give an excellent recommendation when a great job is done!

Wonderful company, both salesman and installers, excellent work from all. The salesman was extremely patient with me as I was deciding what color siding, windows and doors to choose. All products were installed promptly and professionally. Highly recommended to many friends who also have had great results!

We had a wonderful experience with David and his crew at sterling. They offered us a great product and a great price. Install was quick and clean. Very professional at what they do. You have all of our future exterior projects David. Thank you everyone at sterling.

2 months for one window. $500 no installation.

I would recommend this Business, Very Professional and get the job done right. Chaz and Preston did an Awesome Job putting our Gutters on. 1 day and it was finished. Thank You Sterling Windows !!! Gert and Don Showers

Quick process. Great installation team. Kept my property clean and neat. Will definitely call for my next project.

Not a good experience with this company! Today 05/01/20 was the last of install to complete an order made in early October! Early October 2019!!!! Almost 7 months to complete the job. I would think twice before hiring this company. And, oh, something Ive learned. A contract is a 2 way agreement. Add in a reasonable time on the contract to have the install completed by date if you do end up using this company or any vendor. Have them also give you that contract without handwriting.Followup 11-22-20: The response below is not true. The purchase was pre-covid and to be installed about 2 months after that. The 7 month delay should not be blamed for the virus.

Sorry company!! Crooks! In EVERY ASPECT!! My neighbor has been waiting almost 6 months for his windows & when they finally got installed the service was terrible. Also heard its an awful company to work for, bad people to work for & employees dont get paid what they deserve. Dont believe the other positive comments on here. Trust me

We had vinyl done and we are very happy with everyone we dealt with.The company did what we agreed on. The employees (Scott and his son)did a wonderful job. Thank you to everyone involved.

I want to start with the fact that I did alot of research on windows and companies. I choose Sterling Windows because of their promise of great product and price. I was not disappointed. They went over and beyond in their timely and expert windows and service. The windows are unbelievable and the service from the staff at the office,sales people, to their installers was one of the best experiences that I have ever had. They worked in the cold and snow. They showed up early and stayed late. Please do yourself a favor and look no further then this company and these people. I own the Cook Loft in downtown Knoxville. feel free to come by and check out the GREAT job they did. Feel free to call me if you have any questions about these folks. They are the only ones I will call if I need any further help. Thanks guys. Thomas Hensley

I am very happy with the service, install and product. Sterling replaced our windows, shutters, and two doors. They arrived on time, very professional.I had got quotes from 5 different companies before going with Sterling. I was very impressed with their windows. I am a very picky customer and the install men went above and beyond to make me happy. I highly recommend Sterling.

Extremely satisfied with my new windows. Sterling went above and beyond my expectation. The installation team did a fantastic job. I highly recommend Sterling Windows totally happy

I bought a large picture window here, picked it up from their factory, and installed it myself. The window was what I expected, and so far is working out well for me. My only complaint is the mating strip used to join my two large windows together in the center is a little flimsy and easy to knock out during installation. I wish they had a more robust joining method. Otherwise I dont believe youll get a better product for the price.

Great! Windows are the best and the best customer service, dealing with your order quickly to have your window needs solved. Would recommend them!!

Extremely happy with my new windows! Sterling did a fantastic job; very professional and the installation team did a fantastic job. Would highly recommend.

My screen making company...very great to deal with

They did a great job with our window replacements. The crew showed up when they were scheduled and were very professional. They picked up after themselves when they were finished. I would highly recommend them.

Very happy with the staff and especially the quality of the windows. Also happy with the installation process. They gave me a date for installation and showed up on time that day!

Very professional and affordable. This is the second home we have had them work on, and we are so pleased. We’ve had siding, gutters, doors and windows. Highly recommend!!

Very professional and helpful.

No after sale customer service. Once they had my payment I couldnt get the salesman, David Lance, to return my phone call. I feel this is a critical failing of the company.

They might be fine for a full service window install, but my experience ordering a custom window was painful. The staff was tremendously ignorant about their products, repeatedly rude to me over the phone and in person, and never returned any of my calls. I will never use this company again, and I would advise everyone else to do the same.

Super committed to customer care and service. Thanks!

We love our windows from Sterling.

Professional, experienced, schedule quickly.

Called to request a bid for repairs and possible replacement of some Windows. The woman who answered the phone was rude and said we were being too vague and refused to have someone come look at our needs.

The Window and Door People in Knoxville

David Lance came out the day after I called for a quote. He quoted me in 24 hours and was very responsive to my questions. We signed and the door came in a few weeks. When it got in he was able to send out an installer, Randy, the next day. Randy and his helper did a great job and provided great communication. I tried to get 4 different quotes and Sterling Windows was the only one that got back to me over two weeks. Would highly recommend.
