Got new gutters w/ leaf guards from Window World so I would not need to climb the latter and clean the gutters anymore. But because the leaf guard is recessed the branched. leafs and stuff all collect on the leaf guard and now I need to climb the ladder to clean the leaf guards! And above my Bow window the guarder has a back pitch and with a heavy rain it runs out the back of the gutters and down the windows! Will have to get on the ladder to fix that!

I was blown away by the response from Window World. They came out on two separate days, the first for replacing ten windows from our 125 yo house and also a beautiful back door. The second day they came out to replace the roofing on our first and second story porches. Both days they showed up promptly at 8 am and worked steadily through the day. The teams were so friendly and professional under the supervision of Allan and Justin. And the work looks beautiful. I have full confidence that our winters will be cozier and am so glad that the old roofs have been dealt with. I thought the cost very reasonable, quite a bit under my expectations. In short, Window World is the only way to go, Trust me on this.

From Alan who helped me choose a new door and obtain financing, the nice man (sorry I don't remember his name) who measured and explained installation, to Jeremy and Adam who delivered and completed the installation of my BEAUTIFUL new front door - I cannot say enough about the friendliness, kindness, professionalism, and patience of the Window World family. Let us not forget the office personnel!!! All my many, many questions were answered happily and completely and no-one minded me watching the entire procedure. They even beat their completion estimate by several weeks. Jeremy and Adam made me feel as if best friends were installing my door (not a couple of strangers) . I would happily recommend Window World to anyone!!!!!!!!!!

Ryan and his team of installers from Window World came to install a new sliding glass door today and, what an amazing job they did for us. What my wife and I got was, a very high quality door with 2 locking mechanisms for security purposes along with great attention to detail throughout the installation process. This is my second time using Window World and, I would highly recommend them to anyone who is in need of a high quality window or door replacement.

From start to finish, getting new windows (both replacement and new construction) from Window World was a seamless process! The specialists were responsive to our initial inquiry, on-time for scheduled appointments, clear about cost and timeline expectations, and professional in their interactions with us. Specialist, Lanèa, did a great job pulling together the scope of work to be completed and providing an accurate estimate of the cost for the job. The installer, Ariel, and his team were friendly, hard working, and professional when installing the windows in our home. Ariel kept us updated on their progress throughout the day, the team's work was top-quality. We are thrilled with the results and would highly recommend Window World to anyone looking to install new/replacement windows in their home!
Frequently Asked Questions About Window World of Western Massachusetts
What types of Payment methods & Financing do you offer?
We offer a variety of payment methods and financing options (subject to approved credit) depending on the 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?
Generally, replacement windows can be installed within 4-8 weeks from the date that the final measurements are taken. The type of window being installed and type being removed helps determine the amount of time needed to complete the job. On average each window takes about 30-60 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?
Window World replacement windows come with an all-inclusive limited lifetime warranty. Contact us 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 they arrive 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. As a first step, we recommend you visit the Support page of our website for troubleshooting tips and advice on correcting common issues.
