Signs Your Property Needs Professional Soft Washing
Green algae creeping up your siding. Black streaks running down your roof. Mildew stains that come back no matter how many times you rinse them. If this sounds familiar, your home needs more than a garden hose and elbow grease — it needs a professional soft wash that eliminates organic growth at the root.
For Homeowners
Green algae creeping up your siding, black streaks running down your roof, mildew that comes back no matter how many times you rinse it — these are not just cosmetic problems. They are organic growth actively breaking down your home's exterior. Our soft wash kills the growth at the root and protects your siding, shingles, and cedar for years.
For Property Managers
Algae-stained storefronts, dirty fascia, and weathered building exteriors send the wrong signal to tenants and customers. Soft washing restores curb appeal without the high-pressure damage that pressure washing causes to signage, awnings, and siding. We coordinate scheduling around your operations and offer maintenance contracts for HOAs and multi-unit properties.
Soft Washing Solutions for Every Exterior Surface
Different surfaces require different approaches. We tailor our cleaning solutions and techniques to match the material, ensuring a thorough clean without any risk of damage.
Vinyl siding, wood clapboard, and composite materials all collect algae, mildew, and grime — especially on north-facing walls and shaded areas. Power washing these surfaces risks forcing water behind the siding, causing hidden moisture damage and potential mold growth inside your walls.
Our soft wash approach applies a custom-mixed biodegradable solution at low pressure (under 100 PSI — less than your garden hose). The solution breaks down algae, mold, and mildew at the root, then we rinse everything clean with gentle water flow. The result is siding that looks freshly installed without any risk of water intrusion or surface damage.
For homes being prepped for painting, soft washing is an essential first step. It kills the organisms that cause paint failure and creates a clean bonding surface for primer and paint. As a painting company with 65+ years of experience, we understand exactly how surface preparation affects long-term paint adhesion.
Why Soft Washing Beats Pressure Washing on Vinyl, Cedar, and Stucco
Pressure washing forces water under siding and tears up cedar fibers. Soft washing uses low pressure and a mold-killing solution that cleans from the surface inward — and stays clean for years longer. Watch the difference up close before you let anyone aim a pressure washer at your house.

Frequently Asked Questions About Soft Washing
Not sure if soft washing is right for your home? Here are the answers to the questions we hear most from homeowners across Southeastern Massachusetts.
General Questions
The fundamental difference is pressure and cleaning method. Power washing uses high-pressure water (1,300 to 3,100 PSI) to blast contaminants off surfaces. Soft washing uses low-pressure water (under 100 PSI) combined with specialized biodegradable cleaning solutions that kill organic growth at the root. Power washing is appropriate for hard surfaces like concrete driveways and stone patios. Soft washing is the safe choice for siding, roofs, cedar shingles, painted surfaces, and any material that could be damaged by high pressure. We offer both services and will always recommend the right method for your specific surfaces.
