- PSPaul SteinerFeb 5, 20265.0Justin Kempfer knocked it out of the park. On time every time. They have taken care of my mothers house and now another rental of mine. Great pricing, great work.
- SCSteven ChoppJan 29, 20262.0I’m giving 2 stars because I’m satisfied with about half the windows, the inside half. Overall, window world provided me with quality windows and installation. The pricing for the window job was reasonable, and the installation team completed the work efficiently, finishing seven windows in approximately 1.5 hours. However, the estimator did not include the necessary aluminum flashing repair in the original quote. During the quote, I inquired about our older storm windows and if this would be a problem. The estimator told me it would not be an issue. As a result, after installation, there is a visible ring of exposed wood around the window, and the existing aluminum flashing is lifted and no longer meets the window properly. The company has since provided an additional quote for the flashing repair, which is expected to cost approximately $1,400. This added expense was not accounted for when we compared estimates from other competitors, creating an unexpected and significant increase in the total project cost.
- LKLisa KochJan 21, 20265.0We couldn’t be happier with the entire process! From our first interaction with Barry and every single person we interacted with, to every step along the way, it was easy and seamless. From making the first appointment to final cleanup on the day of installation, every single aspect of the job went great! The communication, the people, the product… all top notch! We are 100% pleased!!
- BLBrandon LavergneJan 8, 20265.0Justin came out and measured our windows and was very straight forward. Very easy process. I can’t wait to get our new windows. Don’t even have them in yet and I’m so happy
- TNTyler NeumannJan 6, 20265.0Excellent quality of work and great communication every step of the way. Will definitely be going with Window World for the rest of our windows!

Do you install replacement windows year-round? If so, will I lose a lot of heat/cooling at the time of installation?

Please take down curtains, blinds, or any other window treatments. Security sensors should also be removed and turned off by your security company.

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.
