How to Maintain Aluminum Siding

Aluminum siding is one of the most popular types of home siding because it looks good, tends to retain its “new” appearance for many years, and is relatively easy to maintain. However, to keep siding in good repair does require some care and attention.

Since siding is repeatedly exposed to the elements, the effects of sun, pollution and water will leave their marks. Several problems that siding is prone to are related to the build-up of dust, dirt and pollen. It is recommended that aluminum siding be cleaned once a year.

To clean aluminum siding:

  • Rinse the entire area first.
  • Aluminum siding is lighter in weight than other types of materials used for siding. When using a pressure washer, set it on a lower setting to begin with; a higher power setting might cause dents in the siding.
  • The same applies to the ladder – be careful that it doesn’t scratch or dent the aluminum siding when leaning against it.
  • Start at the top and work your way down.
  • Once the surface is wet, you now can begin cleaning specific areas that need attention.
  • Clean mildew and mold stains with bleach.
  • Remove general grime using a soft brush or cloth to prevent scratching the surface.

Over a period of time, siding can fade. Since paint protects siding from the damaging effects of climate, fading could be an early warning sign that it’s not protecting the siding as it should. Especially if you live by the ocean or in a region that receives a lot of rain, aluminum siding can corrode or rust.

To paint aluminum siding:

  • Clean the area thoroughly.
  • Let it dry before you begin painting.
  • Use a primer on any bare or chipped spots so that the paint will stick to the siding.
  • Give the primer time to dry before applying a coat of paint.
  • Depending on the type and thickness of the paint, you might have to apply a second coat.
