Stop Green Algae & Black Streaks With Soft Washing
If you’re cringing every time you pull into the driveway because the siding looks green and tired—we understand. Long Island humidity makes algae spread fast, and blasting it with high pressure can damage your home. We can help you get that “cared-for” look back without the risk.
What is soft washing (and why it’s safer)?
Soft washing uses low pressure plus professional detergents to break down algae, mildew, and grime at the root. That means no forcing water behind your siding and no etched surfaces—just a clean, bright exterior.
What we safely clean
- Vinyl, painted wood, fiber cement, stucco, and composite siding
- Trim, soffits, gutters, and downspouts
- Fences and even the bases of patio furniture that pick up green growth
Our process
- Protect plants and property, pre-rinse where needed
- Apply biodegradable detergent that lifts organic growth
- Gentle rinse for a fresh, even finish
- Walk-through so you’re thrilled before we pack up
How often should you soft wash?
Most Suffolk homes do well every 12–24 months; shaded/north faces and tree-lined lots may need it sooner.
