Thinking about replacing an old porch this summer. Central
Wisconsin.

What is recommended depth for footings of corner posts?

At least 4 feet. Use Sonotube's BigFoot base if possible. At a
minimum wrap the Sonotube in polyethylene to help keeping it in place
in the face of frost heaves. Most decks don't weigh enough to keep a
straight footing in the ground when there are frequent freeze/melt
cycles.


Sonotubes, yea right, bs , if he is building an addition ok, but this
is a dam Deck, nothing more. Even small sheds you buy are recomended to
have Pads, not foundations to frost. A fence yes, but not a deck.


He is in Wisconsin, and he says the deck is attached to the house. If
the deck is attached to the house, it needs support starting below the
frost line. Having a deck on surface pads heave a half inch or so during
a Wisconsin winter will certainly un-attach the deck from the house,
over time.

It's a porch, NOT a deck.
