Removing an Aluminum Window: A Step-by-Step Guide


Removing an aluminum window can be a daunting task, but with the right knowledge and tools, it can be done with ease. This article will guide you through the process of removing an aluminum window, from measuring the window to installing the new one. It is important to understand the process and follow the steps carefully for a successful window removal.

Measuring the Window

The first step in removing an aluminum window is to determine the size of the replacement needed. To do this, you will need a tape measure and a pencil. Measure the width and height of the window frame at its widest points, making sure to keep the measurements exact. Once you have the measurements, write them down so that you can reference them when shopping for a new window.

Removing the Window

Once you have the correct measurements, you can begin the process of removing the window. Start by using a screwdriver to remove any screws that are holding the window frame in place. Then, use a flathead screwdriver to carefully pry out the aluminum window. If there is any sealant around the edges of the window frame, use a putty knife to remove it. Finally, lift the window frame out of the opening and set aside.

Cleaning the Opening

Before you can install the new window, you must make sure the opening is clean. Remove any debris or residue left behind by the old window. Be sure to use the proper cleaning materials and techniques to ensure that the opening is free of dirt and dust before proceeding.

Installing the New Window

Now that the opening is clean, you can begin the process of installing the new window. Position the window in the opening, making sure that it fits snugly. Secure the window in place with screws. Finally, seal the window frame with caulk or other sealant. Allow the sealant to dry completely before closing the window.


Removing an aluminum window requires careful preparation and execution. Measure the window accurately, remove it carefully, clean the opening thoroughly, and install the new window securely. By following these steps, you can remove an aluminum window safely and successfully.
