Every year, homeowners get the same bad news from a contractor: “Yeah, you’re going to need to replace that whole window.”

And every year, they write a check they didn’t want to write.

Here’s what most of them didn’t know: you probably don’t need to replace the whole window. You just need to replace the part that’s broken.

That’s the sash. And that’s exactly what we do.

What Is a Casement Sash?

The window sash is the moving part of your window. It’s the framed panel that holds the glass and swings open in a casement window. When a window starts failing, it’s usually the sash, not the entire window frame, that’s the problem.

Most homeowners don’t know this distinction exists. Window replacement companies aren’t exactly rushing to tell you about it either.

If your casement window is drafty, sticking, rotting, or just refusing to cooperate, there’s a good chance a replacement sash fixes it entirely. Replacing a window sash only costs a fraction of what a full replacement costs.

Can I Replace My Window Sash?

If you have Caradco, Norco, or another legacy casement window brand, you’re in the right place. Fenster manufactures wood replacement sashes for legacy brands that stopped making their own parts years ago.

Your window frames are likely fine. The frame is just sitting there doing its job. It’s the sash that’s tired. Learning how to replace a window sash is an important step in fixing your windows.

We make an exact replica. You swap it out. Done.

Can I Replace a Window Sash Myself?

Yes, and Ryan walks you through every step on how to replace a window sash in the video below.

The short version: it’s all done from inside the house, the tools are basic, and the trickiest part is probably realigning your lock keepers at the end. Ryan covers that too, along with a few things that trip people up (looking at you, black plastic hinge bushing).

One thing worth knowing going in: your new sash is going to feel tight at first. That’s not a defect. New weather stripping is firm. Give it a few months to settle into the opening and you’ll wonder why you waited so long to do this.
