Brick is one of the most common exterior materials on homes across Greater Cleveland — the classic brick ranches and colonial styles built in the 1950s–1970s throughout Parma, Parma Heights, Fairview Park, Rocky River, and Lakewood are a big part of what makes these neighborhoods look the way they do.
And yes — brick can and should be cleaned. But it requires more care than vinyl siding or concrete.
## Why Brick Gets Dirty
Brick is porous, which means it absorbs moisture and provides an excellent surface for algae and mildew to root into — not just sit on top of. This is why brick often looks cleaner immediately after a rain but darker and streaked in dry weather — the organic growth is embedded in the surface.
In Northeast Ohio, north-facing brick surfaces and areas near foundation plantings typically show the heaviest algae and mold growth.
## What Happens If You Use Too Much Pressure on Brick?
This is the key risk. Excessive pressure on older brick can:
– Damage mortar joints (especially on homes 40+ years old)
– Force water deep into the brick core, causing moisture problems
– Spall or chip softer face brick
– Remove the “fire skin” on old brick, making it more porous going forward
The safe range for brick is typically 500–1,500 PSI depending on the age and condition of the brick and mortar. Older, softer brick (pre-1970s) requires the lower end of that range.
## The Right Approach: Low-to-Medium Pressure + Chemistry
The most effective approach for brick is using appropriate cleaning solutions (sodium hypochlorite or oxygen bleach-based) that penetrate the brick surface and kill the algae and mildew at the root, combined with moderate pressure rinsing.
This combination:
– Cleans more thoroughly than pressure alone
– Is safer for older mortar and brick
– Produces results that last longer (algae killed, not just removed)
## Efflorescence on Brick
If your brick has white chalky deposits (efflorescence), that’s mineral salts migrating through the brick — often a sign of moisture infiltration. Standard pressure washing won’t remove it effectively. Efflorescence requires specific acid-based cleaners (diluted muriatic acid or proprietary efflorescence cleaners) applied carefully.
