House Washing in the Hamptons & Long Island, NY
Salt air, humidity, and coastal storms leave Long Island and Hamptons homes especially prone to algae and mildew buildup on siding.
Rather than blasting your home with high pressure — which can strip paint, force water behind siding, and damage trim — we use a soft-wash process: low-pressure application paired with a biodegradable cleaning solution that kills algae and mildew at the root, then rinses clean without damaging your home’s exterior.
Our Working Process
We make the entire process simple, efficient, and stress-free. From your first contact to the final walkthrough, our team ensures clear communication, professional execution, and outstanding results every time.

What Our Customers Say
Frequently Asked Questions
Most residential house washing projects are completed within 2 to 4 hours, depending on the size of the home, the amount of buildup, and the accessibility of the property.
Because Long Island and the Hamptons experience coastal humidity, salt air, pollen, and seasonal weather, we recommend professional house washing every 12 to 18 months. Homes located near the shoreline or surrounded by trees may benefit from annual cleaning to prevent algae and mildew buildup.
High-pressure washing can damage siding, paint, trim, and other delicate surfaces. Soft washing safely removes organic growth using specialized cleaning solutions and low-pressure rinsing, providing a deeper clean that lasts longer while protecting your home's exterior.
