Ultimately, the best way to take good care of the exterior of your home is to treat power washing as part of routine maintenance. As a general rule, most experts recommend washing the house every 6 to 12 months (or once or twice a year). In general, you should pressure wash your home once a year. If you live in a place that is prone to mold and mildew, I recommend pressure washing it twice a year.
This also applies if you live near a major highway or highway. This question doesn't have a one-size-fits-all answer. Most homes should be pressure washed at least once a year. Pressure washing your coating will extend its life, so it won't need repairs and you won't have to replace it as often.
It also makes your house look like new when it's tidy and clean on the outside. If you're thinking of pressure washing your home regularly, you should try to do it at the end of each season. This allows you to remove dirt and grime. The most important time will be to remove the dust at the end of summer and clean the leaves and sap in the fall.
In general, homes should be pressure washed at least once a year anytime between March and November. As a calendar year approaches, you'll want to make sure your home is well maintained before freezing temperatures and winter weather hit. It's best to think of pressure washing as a routine home maintenance task, as it will help increase the life of the coating, concrete, and all exterior surfaces.
