Just had our windows installed. Very good experience with Mike and Vic. Really cool guys. Install was in a timely manner. They were polite and very knowledgeable. The clean up was excellent as well. You can't tell they were even here.

An amazing experience. The installers, Mike & Victor, were amazing. They arrived on time and did excellent work. Keeping me informed with unexpected bumps along the way, I was able to use their expertise to make informed decisions. Very polite, friendly, knowledgeable, respectful and the best work ethic I’ve ever seen! Highly recommend this company and these installers for your future needs. High quality products, services and warranty! So glad I chose Window World 😁

Highly recommend Window World!!! Don't miss out on this great company. Window World's commercials matchup with my personal experience. This happens rarely.
Salesman Rick was thorough and answered all ?'s day of sale & followup calls. He was up-front about everything, walked me through all the steps
Installer Scott was awesome! (I do not use that word lightly) Scott was prompt, worked very hard ALL day. Put in an 11¾ hr day over ½ the day worked all alone (all the removal & initial installation i.e. lifting by himself) Scott did a very neat, clean job, picking up as he went. Didn't leave a scrap of anything, anywhere. He gave us perfect miters on the inside corner trim work. P.S. He had a great playlist and kept the sound at a very reasonable level.
Thank you Window World for a wonderful experience.

Hello 🙂 I just wanted to send something to say how very helpful Scotty was to my husband and I last night😊 We have been worried about our windows for so long and he just put our mind at ease. He was helpful, knowledgeable and friendly and we truly appreciate it. We also appreciate that Window World is a company that honors and follows Jesus Christ. We will be referring Window World to all who ask & we will be purchasing only from Window World for all of our future window needs. Thank you!

We love our new windows. Mike and Victor were great! They let us know what to expect and kept us informed on their progress. 26 windows in two days. I highly recommend this company and these two men.
Frequently Asked Questions About Window World of Green Bay
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.

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.
