There is no fixed answer to this question. One of the biggest indicators of how often you should wash your house is where you live. The climate can play a big role in how often your home becomes dirty and needs a pressure washing service. Most professionals would recommend having your home washed once a year. Remember: it's unlikely that you are "overwashing" your home, so it's better to wash it more frequently than let it build up with dirt and grime and risk expensive repairs down the road.
