Natural gas. Some sort of butane. Leak was in attic. Growing up gas had a rotten egg smell. So we didn’t realize. Also when we called they kept insisting it was the carpet, the floors, the paint. They would come out and say nothing was wrong and that smell would go away. There was also a carbon monoxide leak that the dector was going off on. That was what make us stupid as shit while dealing with it.
