Floating decks are a cost-effective and versatile option, but they come with some compromises. Since they sit on smaller footings instead of being deeply anchored, they’re more likely to shift over time, especially in areas with heavy rainfall or freeze-thaw conditions. Their low-to-the-ground design makes them more susceptible to moisture buildup and potential water damage.

It’s important to make sure the wood on a new deck is properly seasoned. Seasoning a deck is simple: Once you build it (or have a pro do so), just leave it alone so it can acclimate to the environment. If you don’t give the deck proper seasoning time before staining, the stain can lock in any lingering moisture and cause mold, rot, and other moisture issues down the road. Give the wood at least four to eight weeks to season before you stain.

PVC decking might be long-lasting, but this synthetic material lacks​​ the natural aesthetic or sustainability of wood decking. If you want to match your decking to your new garden furniture or just freshen up the faded surface, it’s not usually possible to paint PVC decking. When comparing PVC to composite decking, PVC is pricier and more prone to warping in hot regions.

You can build an outdoor kitchen on a deck, but you should choose composite decking since it's more heat-resistant. Metal deck materials like steel and aluminum are also good choices because they're less flammable than wood. You should also consider the weight of the kitchen—make sure your deck can support it and any appliances you plan to use. You should consult a structural engineer to confirm exactly how much weight your deck can safely support when building an outdoor kitchen.
