Vinyl siding is the most popular siding material in the United States. It is durable, looks great, and doesn’t rot or flake. However, it does get a dull and dirty look over time. Even more important, it will harbor unhealthy mold, mildew, dirt, bugs, and other unwelcome visitors unless it is thouroughly cleaned periodically. We recommend cleaning your home’s siding every year; keeping it in good repair extends the life of any siding and heads off replacement costs.
