I called Dial One Johnson Plumbing and told them that I had a slab leak. I was told that it would cost $49. to have a plumber come out and locate the leak. When the plumber arrived he told me the service call was $49. and to find the leak was $333. and that he would be 100% accurate in locating the leak. At this point I let him go and find it. Then they wanted $3345. to fix the leak. and I would have to find someone else to fix the tile floor. I called another plumber he came out the next day fixed the leak for $500. including the tile. Also his 100% was 2 1/2 feet off.
