Custom Windows

Design That Works With the Space

Not every opening is square. Not every room follows a grid. Some walls call for a window that breaks the mold – angled, curved, tall, narrow, or completely unique to the home.

ABC Seamless of Janesville installs custom-shaped windows to match the lines, angles, and layout of your home. We work with shapes like circles, half-rounds, triangles, trapezoids, and combinations that don’t fit the usual categories. These are made-to-order and installed to look like they were always meant to be there.

What Makes Custom Windows Different

These windows are common in older homes, vaulted ceilings, tight attic spaces, or anywhere unusual framing gets in the way of standard units. They’re often used to bring in light above doors or beneath angled rooflines, or to mirror existing architectural features.

Sometimes they’re a design choice. Other times, they’re the only way to finish a space properly. We’ll help you figure out if it makes sense, and what it should look like when done.

Key Details That Make the Difference

Custom-shaped windows involve smart planning. The shape affects everything from how the window handles weather to how it’s installed into the frame. Here’s what matters:

Field measurements to match the true shape of the opening
Frame options to line up with other windows in the home
Solid glass or pairing with venting units, depending on the layout
Clean trim that finishes the job without extra filler or patching
A final install that fits without needing to hide mistakes

Why Homeowners Choose Custom Windows

There are good reasons to use a custom-shaped window, and not just visual ones:

Fit in spaces where standard windows won’t
Add architectural interest without changing the structure
Bring in natural light without sacrificing privacy
Work with angled ceilings, high walls, or unusual layouts
Help define the character of a space without being oversized or flashy
