I was called to do estimate for boiler replacement. After discussion the job with the prospect customer, he and his wife asked me to draft the contract. After I sent the contract for their examination, the customer decided to take a quote from another contractor. Here we go again, the buyer’s repentance was made even before the final purchase, the customer started questioning my means and methods, as a matter of fact he challenged me in the fact, that the utility company shall upgrade gas services to the house, another contractor stated that national grid will be installing additional gas services to the house, with an additional new gas meter. After all, he challenged the code requirement to test existing gas piping, which will be connected to a new service.Another plumber told him, it is not nessesary. I pointed out that he and his family would be at jeopardy, if I wouldn’t do the gas tests. So, then he stated, that the other plumber said, a small leak in the gas line is no big deal, and it will be diluted in the air. No biggie. At this point I almost fainted to the floor at this nonsense, and was strained to reject the customer all together. Here is my question: how can the customer differentiate a normal contractor from a fake one? Another question is how my competitors manage to get away with this staff? Any ideas?
