If your driveway, siding, or roof has developed dark streaks or green buildup, you’re not alone. Across Virginia and North Carolina, homeowners are battling a common problem: organic growth.

What looks like dirt is actually living contamination.

What Those Stains Really Are

Black and green stains are typically caused by:

• Algae
• Mold
• Mildew
• Lichen
• Bacteria buildup

These organisms feed on moisture and organic material, spreading rapidly across exterior surfaces.

Why DIY Cleaning Doesn’t Work

Many homeowners try pressure washers from hardware stores. Unfortunately, DIY cleaning often:

• Uses too much pressure, causing damage
• Fails to remove root systems of algae
• Leaves streaking and uneven cleaning
• Causes growth to return quickly

Surface contamination isn’t just cosmetic — it’s biological.

The Importance of Professional Cleaning

Professional exterior cleaning removes organic growth safely and thoroughly. When done correctly, it:

• Restores curb appeal instantly
• Eliminates slippery surfaces
• Protects roofs and siding
• Prevents long-term damage
• Improves property value

Surfaces That Benefit Most

Professional washing dramatically improves:

• Driveways and sidewalks
• Roofs and gutters
• Vinyl siding
• Decks and patios
• Brick and stone surfaces

Why Regular Cleaning Matters

Exterior surfaces accumulate contamination every year. Routine professional cleaning helps prevent buildup and protects the longevity of your home’s exterior.

Clean surfaces aren’t just about appearance — they’re about protection.
