Why You’ll Love Our Vinyl Windows

Quality Construction

Custom Windows Plus vinyl replacement windows are manufactured right here in the USA and backed by our Lifetime Limited Warranty.

Replacement Windows in Wisconsin - Custom Window Plus

Built with maintenance-free u-PVC vinyl, our replacement windows offer amazing durability & resistance to the elements. We use fusion-welded corners, increasing structural integrity which reduces stress on the overall window frame. That helps support and maintains the integrity of our air and watertight seals. The seal is achieved with our triple weather stripping.

When quality counts, you can always count on Custom Windows Plus!

Built For Comfort & Convenience

Our vinyl windows are Energy Star Certified. This means they are independently tested, verified, and certified by the National Fenestration Rating Council for meeting strict energy efficiency guidelines established by the Environmental Protection Agency (EPA).

This ensures you get a window that lowers your energy bills by keeping the elements outside, and your comfortably heated or cooled air, inside.

Many of our vinyl windows feature easy-to-operate tilt-in sashes that allow you to clean the exterior windows from the inside of your home. That allows you to avoid climbing ladders to clean those hard-to-reach second story windows. You’ll spend more time admiring your windows and less time cleaning them!

Custom-Built Especially for Your Home

Trying to fit a specific opening with a “stock” window can result in a change of the actual window opening requiring re-framing and that means additional installation labor & material costs, and plenty of aggravation.

We custom make your home windows to the exact specifications of your window opening. That guarantees you get a window that looks like it was built especially for your home – because it was!

You get the right sized window each and every time from the pros at Custom Window Plus
