The Premier Window Cleaning & Pressure Washing Service
Photo Gallery - Window Cleaning, Soft Washing and Pressure Washing


Scott Dalton started H2Only in 2008 as a window washing service in East Setauket NY with no employees, no business loan, and an unwavering commitment to turn Long Island into a sparkling gem by the sea one squeaky clean house at a time.

His revolutionary process for cleaning windows using pure, deionized water and no harsh cleaning products requires no squeegee or sponge and leaves windows streak-free.

Results speak for themselves and in no time, H2Only had thousands of customers and was busy cleaning the most prestigious homes in Nassau and Suffolk counties.

Scott quickly realized there was a huge unmet need for professional exterior cleaning services. H2Only added low pressure or soft washing services that use pure water to gently clean cedar shingles and cedar shake, solar panels, roofs, and other exterior surfaces.

Hot and cold power washing services clean pool decks, driveways, walkways and more. 

Today, H2Only has expanded with crews that cover all of Long Island, including the Hamptons and Montauk.

H2Only sets the standard for reliable, dependable and professional window washing and exterior cleaning services. Every uniformed technician is clean and screened and dedicated to providing you the white-glove service our customers have come to expect.
