A very common question we get from homeowners is “Do I need to replace the deck substructure when replacing my old deck boards?”

Well…it really depends on the condition of the existing deck substructure. If the substructure is structurally sound and in good condition, it may not need to be replaced when replacing the deck boards. However, if the substructure is rotting, sagging, or damaged in any way, it will need to be replaced to ensure the safety and stability of the deck.

It's important to inspect the substructure carefully before replacing the deck boards. Look for signs of rot or decay, such as soft or spongy wood, as well as signs of damage or stress, such as cracks or splits. If you're unsure about the condition of the substructure, it's a good idea to consult with a professional deck builder or contractor who can help you assess the situation and determine whether replacement is necessary.

In some cases, even if the substructure appears to be in good condition, it may still be advisable to replace it to ensure the longevity and safety of the new deck. For example, if the existing substructure is made from untreated wood or is improperly sized for the weight and load of the new deck boards, it may not provide adequate support and could compromise the integrity of the new deck. In these cases, it's best to err on the side of caution and replace the substructure as well as the deck boards.
