I have used and recommended Quality Plumbing for several years. My only complaint is the assessment or diagnostic fee that is added on to the trip charge. I would have had to pay close to $120 just to be told the faucet cannot be repaired it must be replaced. I'm basically forced into doing the replacement (about $325). I'm not asking for free advice; that's why I have no problem with a trip charge. But this diagnostic charge is not right. And I must say, your rates are the highest. I still use you because I trust you.
