Have you noticed green or black streaks forming on your siding? That unsightly growth is likely algae, and if left untreated, it can spread fast. At Bright & Shiny Window Cleaning & Pressure Washing, we help homeowners restore curb appeal safely with expert soft washing.

Here’s what you need to know about removing algae from siding the right way.

🦠 What Causes Algae to Grow on Siding?

Algae thrives in warm, humid environments—especially on shaded parts of your home that don’t get much sunlight. Rain, moisture, and pollen contribute to this growth, particularly on vinyl, wood, or composite siding.

Signs of algae on your siding:

• Green streaks or patches
• Black or dark stains (often mistaken for mold)
• Slippery residue on surfaces near siding

❌ Why Pressure Washing Isn’t Always the Answer

While pressure washing may seem like a quick fix, blasting algae with high pressure can:

• Damage siding and paint
• Force water behind panels
• Void manufacturer warranties

That’s why we recommend soft washing—a safer, more effective approach.

✅ Soft Washing: The Right Way to Remove Algae

Soft washing uses low pressure and specialized cleaning solutions to gently eliminate algae, mold, and mildew without damaging your home.

Benefits of soft washing:

• Kills algae at the root
• Prevents regrowth for longer-lasting results
• Safe on all types of siding
• Environmentally responsible and non-corrosive

At Bright & Shiny, we customize our cleaning formula based on your home’s surface and severity of buildup.

🧼 Preventing Algae Growth

To reduce future algae buildup:

• Trim trees to allow more sunlight
• Clean gutters regularly to reduce moisture runoff
• Schedule soft washing annually or semi-annually
• Keep lawn sprinklers from soaking the siding
