Casement window sash replacement

Have a casement window sash replacement or repair project? Removing a casement sash for repair or replacement can be simple with these easy steps.

Stationary Sashes

There are several methods to securing stationary sashes, depending on the manufacturer.

1.  There could be visible screws through the edge of the sash frame or the molding around the perimeter of the sash on the inside.

2.  There could be hidden brackets behind the perimeter molding, in which case the molding has to be removed.

3.  Worse case, the sash was nailed or stapled in through the jamb at the factory. In this case, the only way to remove the sash is to find the staples around the sash and break or cut them.

Operable Sashes

Most major manufacturers all use the same brand/style of hardware made by Truth. In general, the following steps will help you remove an operable casement sash.

1.  With the sash open, line up the end of the long arm of the operator with the arrow on the sash track. Push down on the arm to release the roller.

2.  Release the small arm of the operator from the post by prying up on the end of the arm.  If your hardware has a slip pin instead, slide the pin back away from the post to release.

3.  Retract the operator back to the closed position to remove the sash from the hinges.

4.  Release both the top and bottom hinge arm from the hinge post by prying up on the arm at the post, or by sliding back the slip clip.

5.  Slide the sash over to the opening in the hinge track to expose the hinge slider. Once the slider has been removed from the hinge track, the sash will be loose.  Be sure you are ready to bear the weight of the sash at this time.

      Jeff, I am not familiar with that specific model so we wouldn’t have it available, nor am I aware that brand is still available or in production by the original manufacturer or others. However, our specialty is manufacturing obsolete window sash, so it is possible we could produce a replication for you. We could start with some photos of the sash, both interior and exterior. Ultimately, in order to produce a replication, we will require a sample sash sent to us to put through engineering. If you wish to pursue this option, please send photos to and we will be happy to take a look. Thanks!

    I have a 1991 installed fogged stationary casement sash with visible screws through inside molding around the perimeter of the sash into the edge of the sash frame. I am trying to figure out who the manufacturer is. Does anyone have a list of potential candidates?

      Ron, Well, I’m sure we can do that for you, but we need a profile. We have to send you something that will fit in the opening. You have to select one of the sash profiles we have in our catalog on our website.

    I have a 30 year old Marvin Prefinished wood dble casement. Can I get replacement sash for this? One of the sashes is “fogged” up. I also have a 30+ year old Roto Frank venting roof window that the sash is “fogged”. Can you E-Mail me an answer? Thanks!

      Sorry Larry, We don’t handle any Marvin products. You might just try a local glass company if all you need is the glass replaced.

    I am looking for replacement casement sashes. My house was built 16 years ago and I believe that are Crestline. They are vinyl inside and out.

      Laura, We don’t offer Crestline nor do anything with vinyl windows. You’d have to talk to Weathershield about that.
