Plumbing runs in John Comerford Jr.’s blood. His grandfather and father were plumbers. Now one of his sons is, too. “Our name is on our businesses,” Comerford says. “No one in my family has disgraced it yet — and I’m not going to be the first!”Since 1978, Comerford Plumbing has forged a reputation for the highest standards of professional service at reasonable rates in the suburbs west of Cleveland. “We concentrate on basic residential work — drain cleaning and faucet fixing,” Comerford adds.
