I completely agree with this article! In USA also, people tend to hire unlicensed plumbers simply because they charge less. However, many of them have to pay a huge price later onwards. As per a survey conducted by one of the leading plumbing services in New Jersey, http://www.allweekplumbing.com , almost 72% of the population of USA have some time or the other faced plumbing crisis due to negligent hiring of unlicensed plumbers. Often, these unlicensed plumbers violate the safety rules and the customer ends up paying a hefty amount to get the mistakes rectified. Unlicensed plumbers are not insured as well, hence no insurance claims can be put on them.
