It depends on your climate and the type of paint used on your house. In general, you should wash your house every two years. However, if you live in a humid climate or your paint is peeling, you should wash it more often.

It depends on your climate, the type of paint used on your house, and how dirty your house gets. In general, most people recommend washing your house every other year. If you have a vinyl siding, you should wash it at least once a year to get rid of the dirt and dust that can build up and cause the color to fade. If you have a brick or stucco exterior, you don't need to wash it as often since those materials are porous and can absorb dirt and dust. But you should still occasionally rinse them off with a garden hose to get rid of any built-up grime.
