After soaring the open skies as an air crewman inside of military helicopters, Chris Duffy decided to use his fine-tuned leadership, interpersonal, and physical strengths to start a business. Now, instead of restoring order from above, Duffy keeps his feet planted and sends pressurized blasts of water upward onto roofs, siding, and thirsty clouds.

Since its founding in 2005, Duffy's Dirt-be-Gone has rejuvenated the exteriors of buildings ranging from residential homes to hospitals to 25-story hotels. The licensed and insured company uses pressure washers that powerfully spurt out a specially formulated cleaning solution designed by Chris to break up dirt, mold, moss, and algae without damaging plants or treant house guards. Professional technicians arrive at each job dressed in uniform—jeans or khakis with a Duffy's Dirt-be-Gone shirt—and are often accompanied by Chris himself.
