We had 23 large windows installed by Window World, and the whole process was excellent. The crew worked quickly and did a great job with the installation. Very clean. It’s been a year now and the windows are still working perfectly with no issues. On top of that, the price was great compared to other companies. Overall, fantastic value and a smooth experience — highly recommend! Luigi was excellent to work with.

I do not recommend Window World Flemington.
I placed my order back in March and was told installation would take 6–8 weeks. Months later, I still don’t have an install date. The owner, Larry, has been completely unresponsive despite repeated attempts to reach him. This lack of communication and professionalism is unacceptable.
I’ve cancelled my order, filed a chargeback, and will be reporting this to the BBB. Save yourself the frustration—look elsewhere for your window needs.

Poor Quality, Worst Service. No Warranty as Promised. They don't respond to you for warranty services but excuses. No Good.
Frequently Asked Questions About Window World Garden State West
What does "Any Size, Installed" mean?
The term "Any Size" refers to any size replacement Double-Hung window our manufacturer will construct. Currently this is a minimum width and height of 15" X 26" and a maximum of 48" X 78". "Installed" refers to the removal of a basic Double-Hung wooden window and installing your new Window World replacement window, using the existing wooden stops.
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. 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.
