What Soft Washing Removes
St. Louis humidity creates perfect conditions for organic growth on your home's exterior. Soft wash eliminates it all.
Green Algae
The green film on north-facing walls and shaded areas. Our solutions kill algae and prevent rapid regrowth.
Black Mold & Mildew
Dark streaks and spots, especially in humid areas. We treat at the root, not just the surface.
Lichen & Moss
Crusty growths that embed into surfaces. Soft wash penetrates and removes without scraping damage.
Dirt & Pollution
Road grime, pollen, and environmental pollution. Restores original color and brightness.
Oxidation
Chalky residue that makes vinyl look faded. Our process removes oxidation and restores vibrancy.
Spider Webs & Nests
Cobwebs, wasp nests, insect debris. Complete removal during the soft wash process.
Safe for All Siding Types
We adjust our approach for your specific siding material. No one-size-fits-all methods.
Vinyl Siding
Most common in St. Louis. Soft wash removes oxidation, restores color, won't warp or crack.
Wood Siding
Cedar, pine, hardiplank. Low pressure protects wood fibers, won't raise grain or strip stain.
Brick & Stone
Mortar-safe cleaning. Removes efflorescence, algae, and pollution without erosion.
Stucco
Gentle treatment for delicate stucco texture. No chipping, cracking, or surface damage.

How Often Should You Soft Wash?
Frequency depends on your home's exposure. St. Louis humidity means most homes benefit from regular cleaning.
Heavy Shade/Humidity
Homes surrounded by trees, near water, or with north-facing walls prone to growth. Proactive cleaning prevents damage.
Average Conditions
Most St. Louis suburban homes. Enough time for visible buildup but before organic growth causes permanent staining.
Full Sun/Dry
Homes with minimal shade and good airflow. Less organic growth, but pollution and oxidation still accumulate.
Signs Your Home Needs Soft Washing
If you notice any of these, it's time for a professional soft wash.
Green or Black Streaks
Algae and mold growth, often on north-facing or shaded walls.
Faded or Chalky Siding
Oxidation makes vinyl look old. Soft wash restores original color.
Dark Stains Under Eaves
Mildew growth where moisture collects under roof overhangs.
Visible Dirt Lines
Pollution and road grime create visible dirty areas.
Cobwebs and Insect Nests
Signs of neglected exterior that needs attention.

The Physics of Exterior Damage
Clogged gutters don't just look bad—water overflow erodes foundations at $10,000+ per repair. Algae on siding isn't cosmetic; it's actively degrading your surfaces. Prevention costs 1% of the repair.
Foundation Water Damage
When gutters overflow, water pools at your foundation. Freeze-thaw cycles crack concrete. Moisture infiltrates basements. A $200 gutter cleaning prevents $10,000+ foundation repairs.
Algae Root Systems
Gloeocapsa magma (the black streaks on your roof and siding) has root-like structures that penetrate surfaces. Pressure washing breaks the surface; soft wash kills the organism.
UV & Oxidation
Dirty windows block natural light and trap moisture. Siding oxidation accelerates under debris. Regular cleaning extends surface life by 20-30% compared to neglected exteriors.
