The answer to 'how often to clean pressure washing' is that most experts recommend pressure washing your home's exterior surfaces every 12-24 months. This helps remove built-up dirt, grime, and mildew that can damage and discolor your siding, roof, walkways, and other surfaces over time. The exact frequency may vary depending on factors like your local climate, the age and condition of your home, and how dirty the surfaces get.
Regular pressure washing is an important part of maintaining your home's curb appeal and protecting your investment. It can help extend the life of your siding, roof, and other exterior components by preventing premature wear and tear. Many homeowners find it's best to have their home professionally pressure washed every 1-2 years to keep it looking its best.
