Do I Need a Custom Sized Double-Hung Window?

In most cases, you will be able to find a standard double-hung window size that fits your home. That means it is a window size readily produced by most (or all) manufacturers.

However, there are a few cases where you may need a custom window size instead.

1. You have an older or historic home.
2. Your home has unique architectural designs that include non-standard window openings.
3. You are replacing a window that was originally custom-built.
4. You have a specific look or design in mind that may be larger or smaller than a standard size.
5. Your home has structural constraints that make a custom window less expensive than remodeling your home’s structure to fit a standard size window.
