The house next to me is being rehabbed by people who don't know what they're doing. I had 2 gas shut-offs at my house because we thought we had a gas leak. Turns out: it was theirs.

I had to get a stop work order issued, because it was dangerous and expensive for me (First time, BGE shut OUR gas off, and didn't trace the problem to the obvious construction next door. We had to pay AJ Michaels a pretty penny to clear our gas tag that same day).
