Does pressure washing damage brick?
Many homeowners have questions about whether their specific type of house siding can be safely pressure washed. This is a particularly common question among homeowners who live in a brick house: Does pressure washing damage brick? Here’s the thing: If you attempt to pressure wash your home yourself—without professional equipment, experience, or technical knowledge—you are risking damage to your home’s exterior, no matter what type of siding your home has.
The reason for this comes down to one thing: Pressure. When you are pressure washing a brick house, you must take every precaution to apply just the right amount of water pressure: You need enough to remove grime, dirt, and contaminants but not enough to cause damage to the existing brick and mortar. This is true when you are pressure washing any type of brick surface, including brick walkways and patios.
