Had replaced some windows with a different company a few years back. These were rated just as well and were a couple thousand dollars less per window. Out of the 3 estimates I scheduled, Window World was by far the cheapest, easiest, and less painful to get through. The contractor they sent initially to do the estimate was direct, honest, to the point, and willing to work within my budget and schedule. The others not so much. I will absolutely call them again when I replace the rest.
Frequently Asked Questions About Window World of GSV
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.
