Paint vs. Replace

The cost to replace aluminum siding is about $2.20 per square foot. In some cases, you may be able to repair minor dents or blemishes in the paint. Determining whether your siding needs re-painted or replaced is relatively easy. If it has been previously repainted and is now peeling, has large dents across several planks, or you see white rust - which is a sign of oxidation - you should consider fully replacing it.

Maintenance and Length of Life

If done correctly, repainted aluminum can last about 15 years. To achieve maximum life expectancy, the surface has to be properly prepared. Improper preparation will result in premature cracking and peeling. This preparation includes cleaning the surface and the application of paint and primer in weather conditions from 50 to 80 degrees. Always check the forecast before beginning, a painting project can be ruined by rain showers. The length of life can be improved by avoiding impact on your siding. Everyday items such as a stray basketball bouncing into your siding or repetitive impact from the output of a lawnmower can chip away at the paint over time.

Painting Galvanized Steel and Other Metal Siding

For galvanized steel or other metals, you can use latex or acrylic paint. Galvanized Steel will not react to latex paint like aluminum. Your contractor will be able to determine if your siding is galvanized, aluminum, or another type of metal before beginning and will adjust the quote according to the type of paint required. Because galvanized steel does not react causing white powdery oxidation, it is an easier surface to repair. When painting, be sure to scrub off any rust with a wire brush or prepare the surface with a rust-covering primer.
