Mold, algae, and mildew are common problems that affect the exterior surfaces of homes, decks, driveways, and fences. Not only do these growths damage surfaces over time, but they also pose health risks and detract from your home's curb appeal. Many homeowners wonder if power washing mold, mildew, and algae is an effective solution, and the answer is a resounding yes. Power washing can be an efficient and eco-friendly way to restore your home’s exterior and keep it looking fresh and clean.
At EcoWash, we specialize in professional pressure washing services that safely and effectively remove mold, algae, and mildew from a variety of surfaces. If you’ve noticed dark streaks, slippery patches, or discoloration on your home or outdoor spaces, power washing can be the solution you need.

What Causes Mold, Algae, and Mildew Growth?
Mold, algae, and mildew flourish in moist, shaded, and humid conditions. Surfaces that are shaded by trees or receive little sunlight provide the perfect breeding ground for these organisms. Moisture from rain, humidity, and poor drainage can linger on surfaces, encouraging growth.
Mold: A fungus that can penetrate porous materials, causing decay and potential health issues.
Algae: A green, slimy growth that often appears on wood, concrete, and siding.
Mildew: A type of fungus that appears as a powdery or fuzzy growth, typically white or gray.
These organisms not only discolor surfaces but also contribute to deterioration by trapping moisture and causing rot or corrosion over time.
How Power Washing Removes Mold, Algae, and Mildew
Power washing, also called pressure washing, uses high-pressure water spray to remove dirt, grime, and biological growth from exterior surfaces. The force of the water breaks down the mold, algae, and mildew, flushing them away without harsh chemicals.
Here’s why power washing is effective:
Deep Cleaning Action: The high-pressure spray penetrates surface crevices and porous materials, removing embedded mold and mildew that traditional cleaning can miss.
Surface Restoration: Power washing restores the natural color and texture of wood, concrete, brick, and siding by eliminating stains and buildup.
Eco-Friendly: When done properly, power washing reduces or eliminates the need for chemical cleaners, making it a green choice for homeowners concerned about environmental impact.
Power Washing vs. Other Mold and Mildew Removal Methods
While some homeowners try scrubbing or applying chemical cleaners, these methods can be labor-intensive and sometimes ineffective. Scrubbing may remove surface mold but often misses roots or spores deep in cracks and pores, leading to regrowth. Chemical cleaners can damage plants, harm pets, or discolor surfaces.
Professional power washing offers:
Efficiency: Large areas can be cleaned quickly and evenly.
Safety: Technicians know the correct water pressure and techniques to avoid damage.
Long-Lasting Results: The thorough cleaning reduces mold and mildew regrowth by removing spores and stains.

Surfaces That Benefit from Power Washing
Power washing is safe for many exterior materials when performed by experts like EcoWash. Common surfaces include:
House siding: Vinyl, wood, brick, stucco, and fiber cement siding all respond well to power washing.
Decks and patios: Surfaces made of wood, composite, and concrete can be refreshed and restored.
Driveways and walkways: Concrete, asphalt, and pavers look cleaner and safer.
Fences and outdoor furniture: Mold and algae are removed, prolonging the life of these structures.
Power washing can be combined with gentle cleaning solutions when needed to remove stubborn mold or algae.
How Often Should You Power Wash to Prevent Mold and Mildew?
The frequency of power washing depends on your environment and exposure to moisture. In humid or shaded areas prone to algae and mold growth, annual or bi-annual power washing is often recommended. Regular cleaning prevents buildup and maintains your home’s appearance and structural integrity.
