The professionals at Window World recently replaced a large picture window for us, and it turned out beautifully. Their excellent service and expertise was truly appreciated.

We had a ton of work done this summer by these guys and I really can't speak more highly of their work and professionalism. Siding, foam insulation, front porch replacement and most recently a crew replaced a large 2 pane fixed picture window with new double hung opening windows. They showed up right on time, did a great job and completely cleaned up after themselves. Crew leader Ryan, with Kyle and Tyler were GREAT! Thanks guys and thanks Window World!

Could not even get them to show up on time for their appointments. My belief is if you can't show up on time for that then you probably won't be able to deliver your windows in on time or install them on time

I had an amazing experience with Window World. They were professional, prompt, and perfectionist. I didn’t realize that Window World did more then windows, but I am so glad I called. My new garage door changes the look of my entire home! Highly recommend!

We had all of our old casement windows replaced with beautiful double hung and sliding windows. We were pleased with the installation process, the crews were prompt, respectful and friendly. They took care moving about my home and thoroughly cleaned up inside and out. We couldn't be happier with our investment; the windows look great! Nick took the time to show us the mechanics of the windows, shared tips to clean them and answered all of our questions. Window World made the process easy from start to finish.
Frequently Asked Questions About Window World of Western Massachusetts
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.
