Window World of Fond du Lac

I can't say enough good things about Window World of Fond du Lac and the experience we had with our replacement windows. The entire process was wonderful and the windows are amazing! The installation crew arrived early, are efficient and hard working, took good care of our house on the inside, and cleaned up the outside. The fit and finish is great, they look fantastic. My house is quieter and I can already tell we are saving money on our heating costs. Marvin was a pleasure to meet and deal with. Always happy to leave an honest review for such a good company. Wish we had gotten our windows replaced sooner! They make such a difference. Very happy customers!

I got a new bow window, screen door, and main door. They did an excellent job. They were polite. They cleaned up after the installation. I highly recommend this company.

Marvin was great to work with, he kept us updated on our custom window and back patio slider door special order. The installers were great and worked thru the rain to complete the job. Mike checked in on the job to make sure everything was going smooth. Would highly recommend Window World of Fond du lac.

I had originally given Window World a poor review in November 2018. They had installed 18 (middle of the road option) windows and while I enjoyed the quality of the windows, the inside stops made of both pine and cedar weren't installed with much care. They had overhang, gaps and in one case, a large open knot facing outwards. I put the pictures up on Google reviews but have since taken them down, as they no longer reflect the work Window World has done. The new pictures are quite dark but trust me, the windows look much better! Window World of Fond Du Lac reached out to me and has since come back to my house to fix the issues. Matt and Mike personally came to do the work, removed the ill-fitting stops and replacing them with new ones. Despite the difficulties with the original inst

The installers were on time right to the min. They were beyond professional. Took care in protecting my home while they worked by covering the floors during installation. And vacuumed twice after completing the work. Explained everything to me before they left. Answered my questions. Extremely polite. This is the second time we have had them out to our home for improvements. I would absolutely recommend them to anyone. Completely satisfied with Window World and their service crew. Thank you
