We were initially told 6-8 weeks before the windows and the door were to be customized and installed. It has now been 3 months and no windows or door. We have to email them or text them for updates. Now they are saying they are short on installers. I’m now wishing I had gone through another company. I went by the previous reviews. So disappointed

The whole team did a great job of installing the windows. A tarp was placed under each window that the team was working on and cleaned the mess as they went from window to window. Excellent job on installing and caulking. Highly recommended!

We love our new windows, they look so pretty and clean and seems to let more light in the rooms. Hoping to see a difference in the electric bill.

Great experience! We had three different window companies give us guotes and window world was by far the cheapest. Great thing is, we didn’t have to wheel and deal. They gave us the absolute lowest they could go up front unlike the other two companies that had to keep matching. Fast work, and cleaned up any debris as they finished each window. Friendly and very accommodating.
Frequently Asked Questions About Window World of Hattiesburg
What types of payment methods and financing do you offer?
We offer a variety of payment methods and financing options 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.
