Brick looks tough, so many homeowners assume it can handle a powerful pressure washer. It’s true that brick is durable, but high pressure can damage both brick and the mortar between it. If you’re wondering whether you can pressure wash a brick house in Springfield, here’s what to know first.
Why High Pressure Can Damage Brick
- Mortar erosion: mortar is softer than brick, and a strong stream can wash it out of the joints.
- Surface damage: older or softer brick can chip or lose its outer face.
- Water intrusion: forcing water into the wall can lead to moisture problems inside.
- Painted brick: high pressure can peel paint unevenly.
The Safer Method: Soft Washing
Most professionals clean brick with low pressure and a cleaning solution that breaks down algae, mildew and dirt. The solution does the work, and a gentle rinse carries it away. This is the same approach used for siding; see our house soft washing guide.
Common Brick Problems in the Ozarks
- Green or black growth on shaded walls
- Red clay splash-back along the bottom of walls near flower beds
- White residue (efflorescence) caused by moisture moving through the brick
- Rust stains from metal fixtures and downspouts
Tips if You Clean Brick Yourself
- Use the lowest pressure that works, and keep the nozzle well away from the wall
- Test a small, hidden area first
- Wet nearby plants before and after using any cleaner
- Avoid spraying directly into mortar joints, windows and vents
Questions to Ask a Professional
Ask whether they soft wash brick, which cleaning solution they use, and whether they’ll test an area first. Older homes, like many near Ozark’s historic square, deserve extra care. See our Ozark exterior cleaning guide for more on older homes.
Frequently Asked Questions
Will pressure washing damage brick?
It can. High pressure can wash out mortar, chip older or softer brick and force water into the wall. Low-pressure soft washing is usually safer.
How do you remove white residue from brick?
White, chalky residue is often efflorescence, caused by salts carried out by moisture. It usually needs a specific cleaner and fixing the moisture source, not just pressure.
How often should a brick house be cleaned?
Most brick homes only need cleaning every few years, unless shade causes algae or mildew to build up faster.
