Aluminum Window Replacement Tips Aluminum Window Replacement Tips
Aluminum window replacement, contrary to the opinions of some window suppliers and contractors, is generally not done because the homeowner has decided to use a different window material, but because he is replacing old windows with a different size or type of aluminum window. Or, he is replacing an aluminum window that has become damaged. Still, a replacement for any reason will require that the homeowner either hire a professional to do the job, or that he install his new windows, himself. This will mean, if you are the homeowner replacing your aluminum window, you'll need to know something about what it takes to replace your window.
Measuring for Your New Window
Before doing anything else, you'll need to measure your window opening. First, you'll need to be able to see on the window frame which of the flanges protrudes more. You will be able to see this better if you remove the window screen—if you have one attached. Then you'll need to measure the top width, middle width, and bottom width of your window opening. Then measure at these same places for height.
Ordering Your Window
When you order your new window, regardless of the supplier you choose, you'll need to give your supplier the measurements you took of your window opening.
Removing Your Old Window
After receiving your new window, you need to remove the old one. But before you do, you should double check the measurements you took from the window opening, just in case you just might have made a mistake in your measurements. You won't want to tear our your old window until you know for sure the new one is going to fit as it should. Assuming your measurements were accurate, remove the old window screen and moving panel. If you find screws holding them in place, you'll need to remove the screws. If the window has been caulked, it may stick somewhat when you pull it out. If so, it will take a little prying to remove it. Next, you will need to remove the meeting rail.
Installing the New Window
If you're installing your new window in a wall with stucco, check the old frame to be sure the surface near the window doesn't stick out past the siding. For a house with lap siding where the old frame protrudes beyond the siding, this will not create any problems. But if there is a gap, you may want to seal the window by re-caulking. Before permanently installing the new window, you should apply caulking to the frame. But leave one or two gaps near the weep holes. As you insert the new window, you should try to avoid disturbing the fresh caulking you have just applied. You'll make a better seal between window and frame if you push the window firmly against the frame. Make sure the window is level and plumb, so it will operate as it should. You can now secure the window by making screw holes in the frame and driving screws through them and into wall studs.
To cover gaps between the new frame and interior drywall, attach wood, vinyl, or aluminum molding.
