Are you tired of seeing the gray coats of dust staining your home’s facade? Perhaps you think your home is finally ready for a fresh coat of paint? In both of these cases, you might start looking into ways to clean the surface of the walls. After all, new paint isn’t going to adhere to a dirty surface — and those dusty spots should be fairly easy to get rid of. We asked our friends at Pressure Washing Alternatives in Jacksonville, Florida to give us the pros and cons of pressure washing your house.

Why You Should Pressure Wash Your House

What is pressure washing? According to Wikipedia, it is “the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, chewing gum, and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces.” Pressure washing the exterior walls of your house is a surefire way to get the gunk off. However, you should take care to do it correctly, if you want to avoid some of the damage we’ll mention.

Still, if you get people who know what they’re doing to pressure wash the walls, you shouldn’t have any trouble with it. In fact, a capable crew can use a pressure washer to get rid of mold and mildew as well as any loose paint. You’d end up with a clean surface you can patch up and paint as you please.


In fact, while you’re at it, you might direct the pressure washer to some of the wooden exterior elements as well. Pressure washers can easily knock the grime off your wooden deck or railing even at low pressure. They’ll also great for cleaning vinyl fences and asphalt or concrete driveways at medium pressure. Additionally, you can also use it at high pressure for metal and stone surfaces.

The Case Against Pressure Washing Your House

As good as pressure washers can be in the right hands, they can also do a lot of damage in the wrong ones. We’ve already noted that the pressure should be adjusted accordingly for each surface you’re cleaning. A professional cleaning crew would know that.

Conversely, if you were to grab a pressure washer without any prior experience with one, you might even break a window. Furthermore, blasting your walls at high pressure could also:

  • Ruin window screens and weatherstripping seals
  • Damage the mortar on brick houses
  • Chip the existing paint (which may be an issue if you weren’t planning to repaint the walls)
  • Cause water damage inside the walls
  • Encourage mold growth

However, if you treat every surface with care, you’ll be able to avoid all of these possible consequences.

Don’t Try This at Home

Ultimately, when it comes to pressure washing your home, you might want to leave it to the professionals. After all, they’re much more knowledgeable about the way the various materials your home is made of react to pressure. When it comes right down to it, it’s best to keep the pressure low to avoid chipping the paint or causing other kinds of damage.
