- JLJohn LesterMar 10, 20265.0From having built a house in the recent past, to remodeling we have had experience with window companies. So let me just say that Hunter and the family crew did a superior job. They paid close attention to detail. Window World of Knoxville is the best in our book.
- RPRay PierceMar 10, 20265.0Logan and crew from Window Works are professional , neat and do great job
- GLGlenda LyonFeb 25, 20265.0I have used Window World several times. Their products are superior and their employees are much better. We just had a patio door installed from our living room to our enclosed sunroom. It changed everything for us. With a sleeper sofa, it turned the room into a 4th bedroom for guest and the door provides privacy and a noise barrier.

Frequently Asked Questions About Window World of Knoxville
What does "Any Size, Installed" mean?
The term "Any Size" refers to any size replacement Double-Hung window our manufacturer will construct. Currently this is a minimum width and height of 15" X 26" and a maximum of 48" X 78". "Installed" refers to the removal of a basic Double-Hung wooden window and installing your new Window World replacement window, using the existing wooden stops.
What types of payment methods and financing do you offer?
We offer a variety of payment methods and financing options (subject to approved credit) depending on promotional period. Please contact us for more information regarding available options.
Will the replacement windows be installed from the inside or outside?
The majority of our replacement windows are installed from the outside. In some situations it may be necessary to install from the inside. On the day of installation, your installation expert will assess your unique situation and explain the process that will best suit your home.
Do you install replacement windows year-round? If so, will I lose a lot of heat/cooling at the time of installation?
Window World installs replacement windows year-round. An average installation will take only one day. Our crews install one window at a time and are trained to do what they can to minimize heating/cooling loss. The energy savings from your new windows will recover any incremental energy costs incurred during their installation many times over during their lifetime.
How can I prepare my house for my replacement windows?
Please take down curtains, blinds, or any other window treatments. Security sensors should also be removed and turned off by your security company. Please provide our installation expert with a clear path to the window(s) being replaced by moving anything that may be in the way. It is also advisable to remove all wall decorations from the walls close to the windows as they may fall during removal or installation.
How long will it take to get my replacement windows? How much time should I allow for the installation?
Since every window ordered is custom-built to fit your home and design choices, manufacturing times vary. Once delivered, the type of window being installed and the type being removed help determine the amount of time needed to complete the job. On average, each window takes about 30 minutes. Trim work and cleanup will require additional time to complete. An average job will take a single day.
What type of warranty is available for my windows?
All windows and patio doors we sell come with a manufacturer’s lifetime limited warranty and a repair labor guarantee, good for as long as you own your home! Contact us or see our warranties page for more details.
What happens to my old windows?
After installing your new replacement windows we remove all old windows from your property and dispose of them properly. If you wish to keep your old windows or storm windows, please notify the installation crew as soon as it arrives for your installation.
What do I do if there is a problem with the windows?
Most of the issues encountered by our customers are easily corrected and don't necessarily mean that there is a problem with your window. You are always welcome to contact us for help.

At Window World, it's our goal for each and every one of our customers to feel comfortable throughout their home improvement experience.

If there are any concepts you'd like to read up on as you research your options, feel free to download our Industry Terms document.
