Removing a fixed window sash may seem like a daunting task, but with the right tools and method, it can be done safely and efficiently. Whether you need to replace a damaged sash, upgrade to a new window with moveable hardware, or perform maintenance, this guide will walk you through the process.

What Is a Fixed Window Sash?

A window sash is the framed part of a window that holds the glass in place. In operable windows, the sash can move to open and close the window. However, in fixed windows, the sash is permanently secured and does not open, making removal a bit more involved.

Tools and Materials Needed:

Before starting, gather the following tools and materials

• Safety glasses and gloves

• Utility knife

• Putty knife or pry bar

• Screwdriver or drill

• Hammer and chisel (if needed)

• Heat gun (for stubborn glazing)

• Painter’s tape (to secure glass during removal)

Steps to Remove a Fixed Window Sash

Step 1: Prepare the Work Area

Clear the area around the window to prevent damage to furniture and flooring. Lay down a drop cloth to catch any debris. Wear safety glasses and gloves to protect yourself from glass shards.

Step 2: Remove the Stop Molding

The stop molding is the trim that holds the sash in place. Use a utility knife to cut along the edges of the stop molding to break any paint seal. Carefully pry it off using a putty knife or pry bar. If the molding is in good condition, set it aside for reinstallation.

Step 3: Cut Through Any Sealant or Paint

If the sash is sealed with caulk or paint, run a utility knife along the edges to break the bond. This step prevents damage to the window frame when prying the sash loose.

Step 4: Detach the Sash from the Frame

If the sash is secured with screws or nails, remove them using a screwdriver or drill. For older windows with glazing putty, you may need to soften the putty with a heat gun before carefully chipping it away with a chisel.

Step 5: Carefully Remove the Sash

Once all fasteners and seals are removed, gently wiggle the sash to loosen it. If it is still stuck, use a pry bar to lift it out gradually. Be cautious when handling glass to prevent breakage.

Step 6: Clean the Opening

After removing the sash, clean the window frame to remove any remaining debris, sealant, or putty. This step prepares the frame for a new sash or window installation.
