My experience with window world has been nothing but positive. I was a little skeptical at first about the life time warranty. We have had our windows now for 10 years have needed very little service but when we have called everything is taken care of by Eric very professionally and timely

The entire experience from start to finish with Window World of Madison was amazing. The entire team was overly helpful and made the process essentially stress-free. I truly don't have enough good things to say about them! Thank you Window World team for going above and beyond!

We had several new windows installed in our home in 2023. We have had issues with two of the windows and have had to call several times to have the tech come out to look at and fix the windows. I had a contractor at my house for a seperate reason who looked at my window and told me its not sealed properly. I reached back out to Window world about this and had to send pictures and we ultimately needed a new frame as there were significant gaps between the window and seal even after the "fix" I had to reach out two times for an update on the status of the order for our new frame. I was contacted at the end of September and I was told it would be the 1st week of October they would have our new frame and they would be in touch once its recieved to schedule the new install. I have yet to hear they've received our frame and have received no updates and its almost the end of October.
We need new windows on other parts of our home and will not be using window world for the replacement of the other windows.

I had a parts issue with our patio door...the manufacturer referred us to Window World. I dropped by, share my problem and they provided me with a solution. In the not too distant future i will be in need of window and door replacement and Window World will be my first stop. I love quality customer service and that is what i found with this business.
Frequently Asked Questions About Window World of Madison
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.
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.
I'm overwhelmed by all the industry jargon. What do these words mean?
At Window World, it's our goal for each and every one of our customers to feel comfortable throughout their home improvement experience. We try to always explain any construction concepts in terms everyone will know when we're in the home, but we also like to make definitions available in advance.
