Aluminium windows are becoming increasingly popular for their durability, weather resistance, and environmental benefits, as well as for the way they improve the appearance of the home. Replacing your old windows with new installations of this material is not difficult, provided adequate safety measures are taken, and provided you have at least a basic knowledge of building and carpentry. However, before you can install your new windows, you first have to remove your old ones, and if this is not done properly, your installation will not be a success.
Removing Old Windows
For removing your old windows, you need a reciprocating saw, a hammer, a wrecking bar and a knife. This task can be quite dangerous -- you should have at least two people on the job, and always wear gloves and eye protection. If your old windows have wooden frames, the easiest way to remove them is to pull the trim away from the outside of the window, and then go inside the house to take the glass panes out from the inside. Using your wrecking bar, you can prise away the window stops. Window stops are the strips of moulding that keep the panes in place. If the moulding has been painted over a few times, you may have to run the knife down it to free it more easily. For a sash window, first loosen the window stop from one side of the lower pane, and you should then be able to slide the pane out, followed by the upper pane.
