Residential House Washing | Duxbury & the South Shore

If your home's siding has black streaks, green algae, or a general dull, dirty appearance — that's not just cosmetic. Mold, mildew, and algae are actively breaking down your siding, eating into paint, and spreading across your exterior every season. A professional house wash doesn't just make your home look better. It protects it.

TwinStream Solutions LLC provides professional soft wash house cleaning services across Duxbury, Hingham, Cohasset, Scituate, Norwell, Marshfield, Kingston, Plymouth, and the surrounding South Shore. We use low-pressure soft washing with professional-grade cleaning solutions that safely eliminate organic growth at the root — without blasting your siding, damaging trim, or forcing water behind your walls.

Why Soft Washing — Not Pressure Washing — Is the Right Method for Your Home 

Most homeowners assume their house needs to be pressure-washed. The truth is, high-pressure washing on siding, trim, and painted surfaces causes more damage than it fixes. It forces water behind siding, strips paint, cracks caulk, and can void your manufacturer's warranty.

Soft washing uses low pressure — similar to a garden hose — combined with professional biodegradable cleaning solutions that kill mold, mildew, algae, and bacteria at the source. The result is a deeper, longer-lasting clean that won't harm your home's exterior.

At TwinStream, we soft wash every house we clean. No shortcuts. No high pressure on surfaces that can't handle it.
