How to Protect Vinyl Siding

Vinyl siding is the most popular form of exterior home covering in the United States, according to the U.S. Census Bureau. Relatively maintenance-free and attractive, it is usually the choice for of new home builders, as well as for homeowners updating older houses.

There are many things you can do to protect your investment and keep the vinyl siding looking new for as long as possible.

  1. Cover vinyl siding whenever you are painting or staining near it, such as with a deck. This will protect the siding from splatters.

  2. Keep heat sources, such as grills, and combustible materials, like leaves or paint-smeared rags, away from siding, which can melt quickly near heat.

  3. Avoid spraying pesticides, insecticides and weed killers near the siding, as these can stain and cause discoloration.

  4. Clean the siding annually with a pressure washer to remove mold and rust, both of which can damage siding. For particularly difficult spots of mold or rust, try using straight bleach or white vinegar to remove the majority of the stain before pressure washing.

  5. Apply a sprayed vinyl restorer if yours has faded, or is covered with rust and mildew stains that will not clean. These often provide a barrier that resists additional weather-related damage.

  6. Plant trees or bushes to keep direct sunlight away from the siding, such as on the south side of a house where it beats down all day. Sunlight fades and weakens siding over time, allowing it to crack and break.

  7. Paint the vinyl siding, creating a weather barrier. This is specifically recommended for older siding that is already faded and will not clean, as vinyl siding is meant to be relatively maintenance-free.


  • If painting the siding, make sure to use a paint specifically designed for vinyl siding, as the wrong type can be absorbed and not cover, or easily flake off when dry.
