Our Clear Vision
A family tradition of excellence in window cleaning, rooted in Hawaii's unique environment and community values.
From Humble Beginnings to Island-Wide Service
Founded in 2012 by Robert and Cassandra Mullen, ProWinClean started as a small family operation cleaning windows in their Paauilo neighborhood. What began as a way to serve neighbors and make ends meet quickly grew into one of Hawaii Island's most trusted window cleaning services.
We understood early on that the salty ocean air, tropical rains, and volcanic dust create unique challenges for window maintenance in Hawaii. That's why we developed specialized cleaning techniques and solutions tailored specifically for our island environment.
Today, ProWinClean serves hundreds of residential and commercial clients across Hawaii Island, from Hilo to Kona. But despite our growth, we still operate with the same core values: treat every home like it's our own, show up on time, and never settle for anything less than crystal clear results.
