Three Generations of Exterior Cleaning on Long Island
For more than 70 years, our family has helped Long Island homeowners and businesses care for their properties. Today, we carry that tradition forward with window cleaning, power washing, soft washing, and exterior surface care—using the right method for each surface and treating every property with respect.
ABOUT US
A Long Island Exterior Cleaning Company Built on Experience
This business has been part of our family for more than 70 years. What began with window washing has grown into a full range of exterior cleaning services, but the way we work is still personal: show up when we say we will, explain what the property needs, and leave it looking noticeably better.
Some jobs call for pressure. Others need a gentler wash, specialized equipment, or a little patience around older materials and landscaping. We take time to look at the surface first instead of reaching for the same solution every time.
Owner Dave Riemer is proud to carry the business into its third generation. The experience matters, but so do the small things customers notice—clear communication, careful setup, and a final walk-through before we leave.
My family has owned and operated our Long Island window washing and power washing business for over 70 years. I take pride in providing great work and carrying on that legacy.
