It's always a little dicey when you hire a plumber.  Luckily, I found Josh of Leak Doctor Plumbing to be a professional and courteous fella.  We needed the main shutoff valve replaced at our house.  Josh was able to come out next day (on a Saturday, at no extra cost) to do the work in less than an hour.  He explained exactly what he was going to do and gave us the parts/labor cost breakdown.  He replaced the valve & pipe, just what we needed.  Now no more leaking!  He's licensed, bonded, and insured and also quoted us the lowest rate amongst 4 other pros we called.  Good contractor & I'd definitely use him again to cure our plumbing woes.   ROC #244221
