What You Can and Cannot Pressure Wash

Hundreds of YouTube videos prove that few things are more satisfying than watching all that dirt and gunk get pressure washed right off a driveway. But, what else can be pressure washed? And what should absolutely not be blown to bits with the power of water?

What Should Be Pressure Washed

When pressure washing a surface, technique is key. Paint, stains, and seals are important aspects to keep in mind, as a pressure washer can create costly damages if not done correctly. In the broadest of terms, the following surfaces can be pressure washed. We will go more into detail later on best practices when pressure washing, and whether or not it is worth it to use a pressure washer on a particular surface.

  • Driveways
  • Sidewalks and walkways
  • Fences
  • Garage doors
  • Exterior siding
  • Brick
  • Patios and decks
  • Outdoor furniture
  • Gutters
  • Tile roofs
  • Cars and boats

Pressure Wash with Caution

While these things can be pressure washed, there are certain things you must keep in mind. Wood siding, for example, can be pressure washed. But if the pressure is too high, water can find its way under the exterior surface and damage insulation, electrical wiring, or cause mold. Too-high water pressure can also dent aluminum and vinyl siding. So it is not worth pressure washing these things if you do not know what you are doing

Any surface that is painted should be pressure washed by professionals. There’s a certain technique that must be used in order to perform the job properly, otherwise you’ll wash the paint right off! Lead paint should never be removed with a pressure washer. It must be carefully contained instead, since a pressure washer would just blast the chemicals into the air.

Though brick can be pressure washed, weathered brick houses and old mortar can be severely damaged with pressure washing. Any loose material can be broken off, creating costly damages to an already sensitive structure.

Don’t underestimate the power of the pressure washer. While efficient for cleaning, the power and speed with which the water contacts your surfaces is enough to cause serious damage. Do not pressure wash your windows (they will break) and forget about pressure washing your roof if you have asphalt shingles. The force of the water will remove granules that protect your roof.

In general, it’s best not to pressure washing anything in high places, since you would very likely throw yourself off your ladder. Pressure washers are more powerful than you may realize – it can even cut through human skin! So if you’re not sure you should pressure wash a particular surface, leave it to professionals like us.
