Those old aluminum windows on your house were all the rage … in 1973. But now they are rattling in their frames, you can feel the wind blow through them, and, worst of all, they are sucking money out of your wallet in the form of heating and cooling costs. Replacing those old aluminum windows with modern, dual-pane windows will keep your house quieter, cooler in the summer and warmer in the winter. You can save a lot of money by replacing old aluminum windows yourself.
Removing the Old Windows -Remove all the exterior trim from around the old aluminum windows. You can pry this material from the window opening by using a pry bar. Be careful when removing the trim so that you don't cause unnecessary damage to the exterior of your home. Also, you can reuse the old trim if it isn't in bad shape after removal.
