Soft Washing FAQ's

  • What surfaces can be soft washed?

    Soft washing is ideal for delicate exterior surfaces that could be damaged by high pressure. This includes vinyl siding, painted wood, stucco, brick, stone, fencing, patios, outdoor furniture, and asphalt shingles. It's a safe way to remove mold, algae, and grime without harming the surface.

  • Is soft washing better than pressure washing?

    It depends on the surface. Soft washing is the preferred method for surfaces that need a gentle touch—like roofs, siding, and screens—while pressure washing is better for hard surfaces like concrete and pavers. Our team will always recommend the safest and most effective method for your home.

  • How long does soft washing last?

    Most homes only need to be soft washed every 1 to 2 years. The results typically last longer than pressure washing because soft washing kills mold and algae at the root, rather than just rinsing it away.

  • Will soft washing damage my landscaping?

    We take every precaution to protect your plants and landscaping. Our cleaning solutions are applied carefully. Before we begin, we pre-rinse and protect surrounding vegetation to ensure your yard stays healthy and safe.

  • How long does a soft washing service take?

    Most residential soft washing projects can be completed in a few hours or less, depending on the size of the home and which surfaces we’re treating. Larger or multi-surface jobs may take longer, but we’ll always provide an estimate beforehand.

  • Is soft washing safe for older or historic homes?

    Yes! In fact, it’s often the only safe method for older homes. High-pressure washing can cause paint to peel or siding to warp. Soft washing gently removes contaminants without compromising the structure or integrity of your home.

  • How much does soft washing cost?

    Every property is different, so we provide personalized estimates based on your home’s size and condition. What we do guarantee: no hidden fees, fair pricing, and the most thorough clean possible. Contact us for a free estimate.

  • Do you offer soft washing for commercial buildings?

    Yes, we do. Our team has experience soft washing restaurants, office buildings, retail storefronts, HOA communities, and more throughout Nassau and Suffolk County. We’re fully insured and offer convenient scheduling to minimize disruption to your business.
