Brick Cleaning in Houston: Removing Mold and Mildew Without Damaging the Brick
Brick is one of the most durable exterior materials on a home. However, that does not mean it stays clean forever.
Here in the Greater Houston area, our humidity, frequent rain, shade, and landscaping create the perfect environment for mold, mildew, and algae to grow on brick surfaces. Over time, that organic growth can turn beautiful brick dark, green, or almost black.
The before-and-after photos from this project show just how dramatic professional brick cleaning in Houston can be.
At first glance, the dark staining may look like ordinary dirt. In reality, much of what homeowners see on brick is often mold, mildew, algae, and other organic growth.
Fortunately, the right cleaning process can safely remove it.

That Dark Brick Is Often More Than Dirt
One of the biggest misconceptions we hear is that a dirty-looking house simply needs to be rinsed.
Unfortunately, water alone usually will not solve the problem.
Mold and mildew can grow deep within the textured surface of brick and mortar. Therefore, simply spraying the wall may make it look slightly better for a short time while leaving much of the organic growth behind.
Instead, professional exterior cleaning treats the source of the discoloration.
As a result, the brick becomes noticeably cleaner and brighter without unnecessary pressure.
Why Mold and Mildew Grow So Quickly in Houston
Houston gives mold and mildew almost everything they need to thrive.
For example, exterior brick frequently deals with:
- High humidity
- Frequent rainfall
- Shade from trees and landscaping
- Roof and gutter runoff
- Sprinkler overspray
- Dirt and pollen that hold moisture
Because brick is porous, moisture can remain on the surface longer than homeowners realize.
Consequently, the lower portions of brick walls, areas behind shrubs, and sections near water runoff often become the darkest first.
You can see exactly that kind of buildup in these before photos.
How We Clean Brick Without Damaging It
More pressure is not always better.
In fact, using excessive pressure on brick can damage mortar joints, disturb aging brick, and create an uneven appearance.
At APro Pressure Washing, we choose the cleaning method based on the surface and the type of staining we find.
First, we evaluate the brick and surrounding materials.
Next, we apply the appropriate treatment to break down mold, mildew, and algae.
Then, we allow the cleaning solution time to work before carefully rinsing the surface.
Finally, we inspect the area to make sure the cleaning looks even.
The result is what you see in these after photos: cleaner brick without sacrificing the character of the home.
Look at the Difference
This transformation is a great reminder that exterior cleaning does not always require replacing, repainting, or covering up a surface.
Sometimes the original material is still beautiful. It simply needs to be cleaned properly.
After treatment, the natural brick color became much more visible. In addition, the area around the home looked brighter and better maintained.
That improvement makes a surprisingly big difference in overall curb appeal.
How Often Should Houston Homes Be Cleaned?
For many homes throughout Greater Houston, we recommend considering exterior cleaning about every 2 to 3 years.
Of course, every property is different.
Homes surrounded by heavy tree cover or located in particularly damp areas may need attention sooner. Meanwhile, properties with more direct sunlight may stay cleaner longer.
Either way, addressing mold and mildew before the buildup becomes severe usually makes maintaining the home much easier.
