🧪 What’s Actually Growing on Your Home? (And Why It Keeps Coming Back)

Most homeowners think the dark streaks or green patches on their house are just “dirt.”

They’re not.

What you’re seeing is living organic growth—and if it’s not treated properly, it will keep coming back no matter how often you spray it off.

At Building Wash NC, we don’t just clean surfaces—we remove what’s actually causing the problem.

🦠 The 3 Main Culprits on Your Home

1. Algae (The Black Streaks)

Those black streaks on siding or roofs are usually algae, and it feeds on moisture and heat.

It’s especially common in North Carolina because of:

• Humidity

• Shade from trees

• Warm temperatures

👉 The problem:

Algae spreads fast and can stain surfaces permanently if untreated.

2. Mold & Mildew (Green or Dark Patches)

Mold and mildew thrive in damp areas like:

• North-facing walls

• Under gutters

• Around windows

👉 The problem:

• Can affect air quality

• Eats away at surfaces over time

• Keeps spreading if not killed at the root

3. Lichen (The Stubborn Growth)

Lichen is a mix of algae and fungus—and it actually attaches itself to surfaces like roofs and siding.

👉 The problem:

• Extremely hard to remove

• Can damage shingles and surfaces

• Often comes back stronger if not treated properly

🔁 Why It Keeps Coming Back

Here’s the biggest mistake homeowners make:

👉 Rinsing instead of treating

If you only use water (or high pressure), you’re removing the surface layer—but not killing the growth underneath.

That means:

• It grows back faster

• Sometimes worse than before

• You end up cleaning more often
