We had windows installed 21 years ago. Our windows are great. Small issues over 21 years and Window World stood behind their warranty. Still highly recommend. Anderson,SC

Despite living near a golf course, it is still a shock when a golf ball smashes through your office window in the early AM. A quick call to Window World started the process. While my job was relatively small, Morgan and the Team at Window World were fantastic. They found the records for my installation - from many years ago - identified the replacement need, and produced a replacement sash that dropped in like a dream. I also ordered a full length aluminum screen in hopes that it would be a bit of protection, should another ball head my way. To top off my experience, Window World is very supportive of Veterans, which further endeared me. You won't go wrong with Window World!

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.
