It was the weekend over the Christmas holidays when we had a gas leak caused by a faulty "no to code" installation of natural gas connection to my gas stove. I shut off the gas and then called up a number of companies. Situation was urgent as temps were falling to -20 and we were now without heat. Reliable was the first to respond - so I went with them. Darren was prompt and professional. He repaired the problem and brought the installation to code.
