Many times when replacing an existing deck the old framing lumber is taken to the recycling center or the dump without consideration as to how it can be re-purposed. In some cases the pressure-treated lumber that provided the infrastructure for the old deck is still in good condition even when the deck boards are worn out and rotted.
Here are two ideas for re-using your old deck lumber as a way of enhancing your garden, saving money and reducing the amount of construction debris in the land fill.
New Retaining Wall
The photo at the left is an example of a retaining wall for a terraced garden that was constructed entirely of recycled lumber that was salvaged during the demolition of their old deck. Before tearing down the old deck we assessed the condition of the pressure treated framing lumber and then calculated the lumber requirements of the new retaining wall. As luck would have it, there was more than enough good wood from which to build the new wall. The labor needed to pull nails and screws from the lumber before re-using it was much less than the cost of buying new materials. This approach also saved hauling and dump fees and greatly reduced the amount of debris going to the land-fill
