Stucco & Algae
Removal
Specialized soft washing to safely remove black algae, green mold and staining from stucco homes across the Inland Empire — no damage guaranteed.
Algae & Mold Removal from Stucco Homes
The Inland Empire's warm, dry climate with occasional moisture creates the perfect environment for algae and mold to thrive on stucco surfaces. Those ugly black streaks running down your walls aren't just unsightly — they indicate biological growth that, if left untreated, can cause long-term surface damage.
🚫 Never Pressure Wash Stucco
High-pressure washing on stucco can crack the surface, force water behind the stucco layer and cause moisture damage inside your walls. Always use soft washing — low pressure + proper cleaning solutions — for stucco exteriors.
What's Causing Those Black Streaks?
The most common cause of black streaks on Inland Empire stucco is Gloeocapsa Magma — a cyanobacteria (algae) that thrives in humid conditions and feeds on calcium in stucco. It spreads roof-to-wall via rainwater runoff. Our soft washing treatment kills it at the cellular level.

Stucco Cleaning Questions
Will soft washing remove ALL the algae stains?
In most cases, yes — our professional-grade solutions are highly effective at removing algae and mold from stucco. Some very old or deeply embedded staining may require a second treatment, which we'll discuss with you upfront.
How long until algae grows back?
Results typically last 1–3 years depending on your home's exposure to moisture and shade. Homes with heavy irrigation spray or lots of shade may see regrowth sooner.
Is soft washing safe for freshly painted stucco?
Yes — soft washing is actually recommended for painted stucco. High pressure can strip paint; low-pressure soft washing is completely safe for painted surfaces.
