A licensed plumber means the person completed the necessary education or training required to work as a professional tradesperson. Hiring a licensed plumbing service means the people working on your building are knowledgeable about water and gas pipes. If you use unlicensed workers, you run the risk of them damaging your home even further and endangering you by doing faulty work.
They advertising 24/7 service, when I called on Sunday February 11 2018, I was told Sunday service was not available. I even called twice to be sure I heard the correct information. Again I was informed no service on Sunday. I mentioned their advertising said 24/7 service. I was told no service on Sunday. I asked what 24/7 meant and did not get an answer. I am Advantage Plan member but this made not difference. This is a complete waste of money. Don't buy the Advantage Plan. This company is a complete fraud.
