[QUOTE=Mike Goodwin]so you need to pull a mold off the deck before you remove it .

This is what I already said pulling off a mold before detaching the deck. Then You would make the new deck so it over hangs a bit. I got from an old
gentleman who re did decks. What I was not clear on with him was what
do you do with the old dog house. Take out the roof?

a definite mess no doubt. I'd say remanufacturing.
