If you are wondering whether or not to power wash your house, take a good walk around your home – pointing out any spots that look dirty or dingy. We can tell you that on the northern side of your home, you’ll typically find much more dirt – including things like black mold or algae growth. You may see the discoloration on your siding, stone landscaping, asphalt, brick, etc. If you live further out into the country you’ll notice more dust and dirt coating your exterior surfaces.
Exterior surfaces that can be washed using pressure or soft washing include siding, gutters, decks, concrete sidewalks and driveways, fences, retaining walls, and more. Roofs can only be cleaned using soft washing, or low pressure. There’s no real timeline for how often you need to use these techniques to wash your exterior, and you can usually tell just by looking at it. But it is important to note that homeowners living in rural or wooded areas may need to soft wash more often.
