- LWLarry WoodardJul 22, 20265.0Just want to send a special Thank You to installers Justin and Jason for their hard work giving our house a great look with new windows and sliding glass doors. They spent two long and very hot days getting the job done as Tropical Storm Bertha was making her way to town. They got us all buttoned up and looking good. Also a special Thank You to Tiffany for orchestrating all the behind-the-scene magic it takes to make Window World the go-to place for professional home improvements on the Gulf Coast.

Frequently Asked Questions About Window World of Southern Mississippi

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.

Trim work and cleanup will require additional time to complete. An average job will take a single day.
