ProWash was founded in April 2024 by Gavin Kelnhofer and Regan McCarthy—two Windham, Maine locals with a passion for quality work, community values, and helping homeowners take pride in their property.
Gavin is an Engineering graduate of Maine Maritime Academy, bringing a strong work ethic to deliver consistent, high quality results.
Regan, a Business and Economics graduate of the University at Albany, brings a sharp eye for customer service, communication, and operations.
Together, we started ProWash with one simple goal: to provide safe, reliable, and effective exterior cleaning services that homeowners can trust. As lifelong Mainers, we know how much your home matters—and we treat every project like it's our own.
Whether it's roof washing, house washing, or full exterior cleaning, we're proud to serve Southern Maine with professionalism, care, and results you’ll actually notice.
