Window Installation reviews across the US

Installers were very friendly. They worked steadily to complete installing 8 windows in one day. Windows are very good quality with many convenient features.

Jonathan and Kaiden did excellent work. They did everything in a very professional manner, and they are also very personable. I highly recommend Window World and these wonderful young men.

The crew arrived early and worked quickly and efficiently like a well-oiled machine! Cleaned and swept up everything when they were finished and hauled all trash and old windows away.
Windows look great!

I highly recommend Window World!
Two years ago we had our roof replaced by them, we came back when we needed the windows replaced. We knew this company has outstanding quality and installation service.
They replaced all the windows in one house in one day!

We replaced all of the windows in our home during our whole house remodel. Window world came out within a couple of days for a quote. Our quote was done and our order was processed quickly and easily. Our order was delivered well before promised. The installers were professional, prompt and clean. Installation was timely and completed quickly. I would recommend them for replacement windows for anyone!!

Window World was awesome, they installed my new windows and they look great and work great!

Had them come out to quote me some windows and doors. Decided to move forward with the door first which was $4,000 and do the windows in about 6 months. Was told to text my credit card number to my representative which I thought was a terrible idea but I did it anyway. Called the store 9 days later to check on progress and was told they never received the go ahead from my representative. This place is the definition of a crooked fly by night company. Please save yourself the hassle I went through and call a company that does not make you text them sensitive financial information.

Edit to add: The female representative I spoke with when I called the office 9 days after I approved work agreed that sending or asking to send credit card information through text was a terrible idea, and there was no record of me approving work. She asked if I would like a new representative to come out and re quote the job. To this I answered yes and shared my concerns and distrust with the previous representative. Less than 10 minutes later the original representative called my phone and said “if you want the door it’s still $4,000” beyond unprofessional. All I was trying to do was make some repairs to my house. Window World turned it into some big fiasco, I feel embarrassed for your company the way this situation was handled.

We had some windows replaced by Window World a few years ago and have been happy with them. Today we met with Kevin Groce to have more replaced. We’re happy with the price, quality, and service of Window World. Kevin made the process of ordering more windows easy and we enjoyed talking to him.

This is the first time we committed ourselves to getting more than one bid on having our old leaky French doors replaced with sliding glass. I'm sure glad we did. Window World had the best price and the salesperson was very knowledgeable about the product. Both the upstairs and downstairs doors were installed the same day (a nice surprise)! The doors have really opened up the view to our back yard and they slide so easily they almost open and close by themselves. The financing made it easy to afford so we didn't have to go through another winter with doors that were cold and wouldn't stay shut. I will not miss the arguments about who didn't shut the door all the way either. You have first dibs if and when we replace our siding, which is another story....

I had some old wood windows and an entrance door replaced in my garage. Everything went well. The install looks better than expected and the installers did it all in one day. Very pleased with the whole process and will call them again next time I need more windows.

I had a great experience with Logan! His communication was great with me coordinating the appointment and thoroughly inspecting all my windows, as well as demonstrating his excellent skills caring about the product performing and reviewing the maintenance of it, the install of window and measurement for replacements! Thank you Logan.

Highly recommended!!! Window World did an excellent job at replacing our old windows. Very professional staff and excellent installation service! From our first encounter with consultation and estimate, and until the last day of windows being installed, it was flawless and super easy!!

We had 2 other estimates and Window World beat their prices, and we got better quality windows as compared to the other large market competitors! We saved over $13,000! I wouldn’t look anywhere else!! Go with Window World!

We had 18 windows and a basement slider/hopper replaced and they are absolutely perfect. I love the quality of our new windows and how much they highlight our 100 year old Craftsman home. We are so pleased and highly recommend Window World!

I am very pleased by the service provided by Window World for my new back sliding door. Everyone I worked with in order get this new door installed was such a pleasure to work with and took time to ensure that I got exactly what I wanted. The installation was the cherry on top as my installers Jonathan & Kaiden where friendly, timely, and very complimentary of my home. I highly recommend Window World for any of your home needs.

Guys did a great job replacing window. They were friendly and courteous. I am pleased with the installation. Window was replaced by Logan, Matt and Kaiden. Thanks to the guys for great service.

We had such a great experience with Window World! Hunter Williams and his crew were quick, friendly, and answered any questions we had. We had a terrible experience with another window company in town, and from the beginning the first person who came out, wish I could remember his name, explained everything in a concise way, didn't do a big long sales pitch, and the price was super reasonable. Our new windows look amazing, we are so happy with our experience!

We got windows from them a few years ago during covid and it went good enough so we came back to get windows for our new house. The windows look great but that's where the positive things stop. The install finished August 8th and a window was broken. Here we are on Aug 30th and it was supposed to be installed today and they called and said they had to cancel with 6 hours notice because the service tech called out sick conveniently on Labor Day weekend and nobody else can come install it. So rescheduled to Sept 4th, the window has been at their warehouse over a week now so that wasn't the issue. The installers were nice enough but they were on break as much as they were working. The windows are disgusting and every single one of them needs cleaned, when I brought this up I was told "we don't have a window cleaning service". They destroyed our trim when installing the windows, trash all over our roof and screens came with holes in them. This was a VERY expensive job with a very frustrating experience and the communication has been extremely bad in all regards as well. I definitely would never recommend Window World after this experience. I do know from the first time I got Windows until this time the owner changed and I can tell you all the prices went up drastically as well. Check the included photos!

First of all ,we had a fast response on the first phone call we made to them. We were told a salesman would be out to talk to us. Scott M. came out and gave a price for new windows in our house. We agreed on four windows being installed. Scott told us the price would be in effect for 1 year. David was our installer, he was great at his job.He cleaned as he worked. David showed us all the details of the windows and how to use them. The windows were so much more than we thought they would be . We are very pleased with Window World.
We recommend this company. Sincerely Linda and Allen H.

Kevin was incredible at coming out and discussing door options with us. It was a great experience getting to talk with him! I highly recommend this company to anyone seeking these services. Not only are they the most affordable, but talking with them has been truly enjoyable. Kevin is fantastic, and we couldn't be happier!

I’m so pleased with my new windows. 18 in total, all installed in 1 day about 3 weeks earlier than anticipated. The crew did an excellent job, cleaned up afterwards and were very courteous.
I chose Window World of Knoxville because they scheduled quickly for the initial visit to get measurements and give me a quote, unlike the other company I contacted who didn’t call back until 5 days later.
I highly recommend them.

We checked out other companies here in Knoxville before we chose Window World. We had a very good experience with Window World for 3 doors & 29 (!) windows this October.
The sales rep took all the time we needed to answer our questions with no pressure. The door crew, Jonathan & Kaiden, were skilled. Our house was built in the 60s so skilled door hangers was a must for us.
The window crew was very good also. They did all the indoor work quickly first so that they minimized our household disruption. We appreciated their good work & tidy cleanup. They cleaned the windows so nicely before they left. We were very satisfied.

After securing 3 estimates for replacing 9 windows and a door at our home, the staff at Window World best helped us understand how changing out our windows with their products would go smoothly and affordable. They walked us through the entire process, including payment. We went ahead and ordered the nine windows to replace our existing windows and a beautiful new door. The technicians were extremely professional, timely, industrious and cleaned up very nicely after they completed their work. I highly recommend Window World for your next window project. They are great!
