🧼 Green Stuff on Your House? Here’s What It Is (And Why It’s a Problem)

If you’ve noticed green streaks, blotches, or film on the side of your house, you’re not alone — and you’re not just looking at “dirt.”

That green stuff is likely algae, mildew, or mold, and it can cause more issues than you might think.

At Prestige Pressure Washing, we’ve helped thousands of homeowners across Dayton and the Miami Valley safely remove these invaders with a professional soft wash system that cleans deep without damage.


🍃 What Causes Algae or Mildew on Siding?

Warm, humid weather + shady areas = the perfect environment for Gloeocapsa magma (algae) and mildew to grow. These organisms cling to your siding and thrive when:

  • Your home is shaded by trees or buildings

  • You have poor airflow around the house

  • The siding hasn’t been cleaned in a few years

  • Moisture builds up on north-facing walls

You’ll often see it on vinyl, stucco, Hardie board, or painted wood siding — especially in spring and summer.


⚠️ Is It Dangerous?

It can be.

While not always hazardous to your health, mildew and mold spores can trigger allergies — especially for kids, pets, and anyone with respiratory issues.

More importantly, algae and mildew break down your siding’s surface over time, trapping moisture and causing:

  • Fading, warping, or cracking

  • Early paint failure or wood rot

  • Lower curb appeal (and home value)

  • HOA violations or insurance issues


💧 The Safe Way to Remove It: Soft Washing

The worst thing you can do? Blast it with high pressure. That often forces water behind your siding, creating even more growth and hidden damage.

Our soft wash method gently applies eco-friendly, biodegradable cleaning solutions that:

  • Kill algae, mildew, and mold at the root

  • Loosen stains, streaks, and grime

  • Rinse clean with low pressure and no damage

  • Keep your siding looking new for longer

It’s 100% safe for all siding types and backed by over 18 years of trusted results.
