Stucco Cleaning & Soft Washing in Houston, Texas: Safely Removing Mold and Mildew Without Damage

One of the biggest concerns homeowners have when they call us is whether stucco can be cleaned without causing damage.

The answer is yes—when it’s cleaned correctly.

This Houston homeowner noticed mold and mildew beginning to grow on the dormer windows and chimney of their beautiful stucco home. Like many homes throughout the Greater Houston Area, years of humidity, rainfall, and shade had created the perfect environment for organic growth.

Fortunately, this is exactly the type of project we specialize in.

At APro Pressure Washing, we’ve spent more than 24 years helping Houston homeowners safely restore stucco using professional soft washing techniques instead of high pressure.

Why Mold and Mildew Grow on Stucco Homes

Houston’s climate is ideal for mold and mildew.

High humidity, warm temperatures, frequent rain, and shaded areas allow organic growth to develop on exterior surfaces. As a result, homeowners often notice black or green streaks on:

• Dormer windows
• Chimneys
• Stucco walls
• Window trim
• Upper elevations
• Gables

At first, these stains may seem like ordinary dirt. However, they are typically mold, mildew, algae, and other organic growth.

If left untreated, the stains usually continue to spread over time.

Why We Soft Wash Stucco Instead of Pressure Washing It

Many homeowners are surprised to learn that stucco should not be cleaned using high pressure.

In fact, excessive pressure can damage the finish, force water behind the stucco, and even create cracks or moisture issues.

Instead, we use a professional soft washing system that combines specialized cleaning solutions with low-pressure rinsing.

This process:

• Eliminates mold and mildew
• Restores the original appearance
• Protects delicate stucco finishes
• Cleans evenly without striping
• Helps keep surfaces cleaner longer

Because we’re cleaning the organic growth—not just blasting it with water—the results last much longer.

A Houston Stucco Transformation

For this Houston project, the mold and mildew were concentrated around the dormer windows and chimney.

These elevated areas tend to stay damp longer, making them especially susceptible to organic growth.

First, we carefully applied our professional soft wash solution to break down the mold and mildew.

Next, we allowed the cleaning solution time to work before gently rinsing the surfaces.

As a result, the black streaks disappeared, revealing clean stucco without damage.

The homeowner was thrilled with the transformation, and the home immediately looked brighter, cleaner, and better maintained.
