"House gets cold," laughs Johnson.

Oh, and one other thing: Johnson says to find your main water shut-off.

If you're going away for the weekend, just turn it off.

That prevents pipes from freezing.

And if you're worried about a particular pipe near an outside wall, just keep water running from it at a very slow pace.

The analogy is, lakes freeze but rivers don't, so best to keep the water moving.

"Water flowing through the pipes is not going to freeze as easy," suggests Johnson.

Homeowners with faucets and pipes below that are close to an outside wall, should just open up the cabinet.

It lets the warm air from your home into that cabinet space and keeps those pipes warmer.

And if you think a pipe might be frozen, don't do anything drastic.

Just call the experts.
