Got gas line insurance from Columbia, my local provider. At the recommendation of the the tech who turned on my service when I moved in.

Had to use it in less than 2 years of moving in. Gas leaking at the sidewalk, right at the cutoff.

They sent some hillbilly contractors who rented a small back-hoe, and got the job done in a day. Cost me nothing (other than the $3 a month on my bill), my biggest complaint was the grass. I bought and watered good seed, and someone showed up 2 months after just as it was starting to take root and threw some straw/seed down on top of it.

9/10 would recommend.
