How to Remove a Sash from an Aluminum Window Frame: A Step-by-Step Guide

Removing a sash from an aluminum window frame can be a straightforward task, but it’s essential to follow the proper steps to avoid damaging the window or injuring yourself. Whether you need to replace a broken pane of glass or simply want to clean the window, this guide will walk you through the process of safely removing the sash from your aluminum window frame.

Preparing the Window

Before you begin, make sure you have the necessary tools on hand, including a screwdriver, a utility knife, and a pair of gloves. It’s also a good idea to have a clean, flat surface ready to place the sash on once it’s removed.

Locating the Sash Stops

The first step in removing the sash is to locate the sash stops. These are typically small plastic or metal pieces that hold the sash in place within the frame. Depending on the design of your window, the sash stops may be visible or hidden behind the jamb liners.

Removing the Jamb Liners

If the sash stops are hidden behind the jamb liners, you’ll need to remove them first. Gently pry the jamb liners out of the frame using a screwdriver or utility knife. Be careful not to damage the liners, as you’ll need to replace them later.

Tilting the Sash

Once the jamb liners are removed, you should be able to see the sash stops. Use a screwdriver to gently pry the sash stops out of the frame. With the sash stops removed, you can now tilt the sash inward, starting from the top.

Lifting the Sash

As you tilt the sash inward, lift it slightly to clear the bottom of the frame. Continue tilting the sash until it’s completely free from the frame, then lift it out and place it on a clean, flat surface.

Reinstalling the Sash

To reinstall the sash, simply reverse the process. Place the sash back into the frame, making sure it’s properly aligned with the bottom track. Tilt the sash back into place, then replace the sash stops and jamb liners.
