No, they're hooking up a gas stove so you'll most likely smell gas for a while.

Ask them. It can't hurt anything to ask and set your mind at ease.

have a smoke and THINK about your question!

So I just moved into a house and the gas company was just in my kitchen hooking up my (gas) stove. They're in thae crawl space now doing something with the water heater. But I smell gas in my kitchen. Should I be concerned?
