The outside tap at the back of our house was leaking.
We called J & S Plumbing Service and agreed to a $40 minimum service call charge. Technician Wayne arrived a couple days later.
After a two-minute assessment, he told us that the hose bib (tap) had to be replaced, and that it would cost $350 plus tax! We refused and asked him to leave. He immediately dropped the price to $227, which we also refused. He wrote up the work order quoting the lower price plus $40 service charge, we paid the $40 plus tax and he left.
I went to Home Depot, purchased a hose bib for under $10, and installed it myself in 16 minutes. I have little plumbing experience.
This event suggests that J & S Plumbing has an hourly rate of somewhere between $1,300 and $800 per hour, plus a $40 service call charge to show up. It seems that the price you pay depends on how much you resist their wild estimates.
Strongly suggest that people shop around before calling this company, and have a firm idea of cost before you end up paying them $40 for ten minutes giving you an outrageous estimate.
