Yes, when done correctly. We use soft washing (low-pressure with specialized cleaning solutions) for delicate surfaces like siding, roofs, and wood, and high-pressure washing only where appropriate (concrete, pavers). Our technicians are trained to select the right method for every surface.
Most residential jobs are completed in 2–4 hours. Larger properties or multiple-service bookings may take a full day. We'll give you a time estimate when you schedule your appointment so you can plan accordingly.
You don't need to be home as long as we have access to an outdoor water spigot and the areas to be cleaned. We'll communicate before arrival and send a completion notice when we're done. Most customers prefer to be home for the final walkthrough, but it's not required.
Absolutely. We use eco-friendly, biodegradable solutions that are safe for children, pets, and landscaping. We also take care to rinse landscaping near cleaned surfaces before and after treatment.
Yes! We offer bundle discounts when you book two or more services in the same visit. We also offer seasonal promotions, so mention a bundle when requesting your quote to get our best pricing.
We serve all of Nassau County and Suffolk County on Long Island, including but not limited to: Garden City, Hempstead, Huntington, Smithtown, Babylon, Islip, and surrounding communities. Contact us to confirm your area.
We recommend having your home exterior washed once a year, typically in the spring or fall. Driveways and patios can benefit from annual or bi-annual cleaning. Gutters should be cleaned at least once a year, or twice if you have heavy tree coverage.
