Our Story

18 years of windows,
done right

Custom Windows Plus has been serving homeowners across the Green Bay area for 18 years. We started this company with one goal: give local families a reliable, no-hassle way to replace their windows and doors. That goal hasn't changed.

Over the years, we've sold and installed more than 3,000 windows per year. That kind of volume means we've seen nearly every window situation a home can throw at us. Old wood frames, failed seals, drafty patio doors — we've replaced them all, and we know how to do it right.

Hello. Just wanted to give a shout out to the young men from Iowa that installed my windows yesterday in Wisconsin Rapids. They did a wonderful job. Hard workers. The windows look great. These guys were dedicated young men. Thanks again!

Best price around!!! Saved me thousands. Very communicative and friendly office staff. The installation crew were kind, efficient, courteous and completely cleaned up after work was finished. Overall, I can not say enough about how great this company was to work with. The quality of the product seems great too BUT the real test will be when winter hits in a few months and that was the reason for replacing my windows in the 1st place. Fingers crossed.
