Our Washing Standards


Environmental consciousness drives United Mobile Power Wash operations. We remain vigilant about water-saving techniques, strictly adhering to Department of Environmental Quality mandates.


Our power washing services utilize a unique combination of steam and hot pressurized water that can also clean mold, mildew, grime, and even years of dirt build-up.


We offer 360-degree, full-slate power washing services that ensure your assets stay clean. First impressions are not only made at your front door, they are made from the side and rear doors, parking lots, fleet, and more.

Our History

Our journey began in 1987 with our founder, Dennis D’Arcy, who had a vision of creating a family-oriented business. Working alongside his wife Ann and their four sons, United Mobile Power Wash, Inc. was born—a power washing company dedicated to serving fleets and commercial businesses.

In 2000, Dennis and Ann retired, passing the torch to their daughter, Bridget (D’Arcy) Mahrle. Bridget developed a close bond with Gordon Mahrle, one of our earliest washing contractors, and the two fell in love. With Gordon’s extensive 28 years of cleaning experience and Bridget’s proactive approach, United Mobile Power Wash experienced rapid expansion, solidifying its reputation as one of the nation’s premier providers of power washing and commercial cleaning services.

Today, United Mobile Power Wash, Inc. stands as a testament to family values, dedication, and entrepreneurial spirit, serving as a trusted leader in the power washing industry.
