The author tries to coordinate schedules so that construction of the new deck can begin even while part of his crew is finishing up demolition of the old one.
The author’s crew also uses the Demo-Dek (greentektools.com). It has a jaw design that doesn’t require a joist or beam for leverage, and that holds the deck board in place after it has been removed.
The author’s crew uses several different decking-removal tools, including the Duckbill Deck Wrecker (deckwrecker.com), which has steel jaws designed to straddle single or double 2-by framing.
Old joists and ledgers are rarely structurally adequate or flashed properly, and must be removed and replaced.
During demolition, old PT framing that is in reasonable shape and that can be reused or recycled is stacked and set aside, rather than sent to the landfill.
A cordless circular saw is handy for cutting old decking and framing to length so that it stacks efficiently in the back of a pickup truck or in a cargo or dump trailer.
