They are lucky that I'm given them 1 star. It would seem like someone with so many years of experience should be able to give me an estimated cost if I exactly I describe that there is an exactly 1/2 crack on my gas line which is located immediately after the gas meter. Instead they want to charge you to come to see that so called "unknown work" like they put it and then charge you an arm and a leg to do repair what turned out to be a small crack then what I stated above. I do not recommend them.
