This story shows you how make repairs to aluminum siding.
Most aluminum siding joins together much like vinyl. Patch a damaged area or replace a panel.
Metal corner caps are sometimes used instead of corner posts for aluminum siding, and in older installations they were often used for wood or hardboard lap siding as well. If your local supplier does not have caps to match the ones on your house, check online sources; it helps if you know the manufacturer's name. In a pinch you can cut and shape a piece of sheet metal to fit, using an old cap as a template.
Aluminum siding can and should be painted. Scrape any flaking paint, and sand smooth. Pressure-wash and allow to dry. Apply an alcohol-base primer, or an oil-base primer that has been thinned with 2 cups of thinner per gallon of primer. Apply acrylic paint.
Less than an hour for most repairs
