- CSCathy ScottAug 15, 20255.0From beginning to end a seamless & painless process, and can’t be happier! Salesman Michael was great with communications making sure we were getting exactly what we needed and wanted. Any general questions (i.e. what to expect next, financing, scheduling, billing) were quickly answered by the great office staff of Laura, Anna and Hannah. They always answered with a cheerful voice and never made you to feel like you were being a burden or pain. Our biggest kudos and shoutout is to our installer Robert Linblad! His consideration for our home, workmanship, and were beyond compare. He explained the how and the whys. The finished product is outstanding. In addition the belief of a strong warranty and support made this a great value.

- TLTommy LesleyJul 7, 20255.0Sorry for being late writing this review for work done on June 23, 2025. There were awesome employees named Rob, Memphis & Rico that did an amazing on my patio door along with the back side of the house windows. These guys are top notch and highly recommend them for my future window needs.
- BCBootie CothranMay 24, 20255.0I had a great experience with Window World, from the sales visit to the installation.
- MMMichaelMay 17, 20251.0We are shopping for windows and doors replacements for our home and after reading all the Negative reviews and "horrible" experiences, we feel it's safe to say we won't be taking quotes or dealing with Window World. Sad thing is before we dug in to Window World because it's such a big project, we thought they were supposedly a great organization to work with, but had we not done our due diligence we could have as well fallen prey to this company. Folks do your research..... it's all out there and even here on this page is enough to throw up tons of red flags. ***** To be 100% clear, we did exactly zero business and had no communication with Window World, this review is based solely on all of the information we ascertained while reviewing them as a possible organization for our project *****
Frequently Asked Questions About Window World of Upstate
What types of Payment methods & 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?
Generally, replacement windows can be installed typically 6-8 weeks from the date that the final measurements are taken. The type of window being installed and type being removed helps 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?
Window World replacement windows come with an all-inclusive limited lifetime warranty. Contact us 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. As a first step, we recommend you visit the Support page of our website for troubleshooting tips and advice on correcting common issues.
