Jarrett Mohn co-founded Hard Knox Plumbing in Knoxville in 2023 with Danny Ferris and leads the heavier side of the work — water and sewer line replacement, repipes, and new construction rough-in. If a job involves excavation, permits, and inspections, it is usually his.
He insists on a camera inspection before recommending any line repair, on the theory that homeowners deserve to see the problem they are paying to fix. Before Hard Knox he apprenticed at Hiller Plumbing, Heating, Cooling & Electrical. He writes the Hard Knox blog from what he sees in Knoxville homes every week.
