Replacing the windows in your home can improve energy efficiency and decor.

How to Remove a Large Aluminum Window

by Maria Magher

Old aluminum windows can lose their energy efficiency or can make a house look dated, causing you to want to replace them with wooden or vinyl windows. You don't have spend a lot of money on the job by hiring a window-replacement company. You can save hundreds of dollars by removing the old aluminum windows yourself.

Place masking tape in a large "X" pattern over each of the window panes. This will minimize shattering if the window should accidentally break during removal.

Remove the trim by pulling it away from the wall, using a pry bar.

Cut through the aluminum window stop on one side of the window, using a reciprocating saw. Remove the window stop.

Lift up the panels of glass and remove them from the frame.

Unscrew the aluminum frame from the frame of the house, using a drill. Alternatively, if you cannot locate the screws or if the screws have become wedged into the frame, cut out the frame, using a reciprocating saw.

Remove the frame. Use a pry bar to loosen the frame even after the screws have all been removed, if necessary.

Items you will need

  • Masking tape
  • Pry bar
  • Drill
  • Reciprocating saw
  • Utility gloves
  • Safety goggles


  • Have your new window in hand before you take out the old one. Don't remove it in anticipation of the window arriving, only to find out that there's been a delay and now you have a big hole in your house.


  • Always wear safety goggles when using power tools.
  • Work with a friend who can help you to remove the panes of glass. Windows can be heavy and you may drop the glass or seriously injure yourself if you attempt the job alone.
