Deck Maintenance FAQs, answered by experts

While you can use various materials like sand or even just soil, gravel is widely considered the best option to put under a deck. It provides excellent drainage and is resistant to water, fire, and pests. Gravel also helps anchor the soil to prevent erosion during heavy rain and acts as a built-in weed blocker, reducing regular upkeep. Furthermore, it is simple to spread, available in various textures and tones, and adds a polished look that complements any deck design.

Always sand a deck before repainting so the wood is smooth and ready for paint. While you do not need to fully remove paint before repainting, sanding helps remove any areas with weather and sun damage. Sanding also helps remove chipped or flaking paint and opens the wood pores to improve paint adhesion.

Composite decking requires a solid foundation, substructure, or subframe to ensure stability. This base is typically composed of posts, beams, joists, and footings. The frame's joists can be built from various materials like composite, plastic, timber, or metal, as long as the base can support the deck's weight without shifting. A professional deck builder might recommend installing the frame on a solid concrete base for added durability. The final design and materials for the substructure will depend on your budget, the type of deck, and environmental conditions.

Pressure-treated wood contains preservatives that give the material internal protection from rot and pests. Untreated lumber won’t last more than a few years unless you choose a more expensive wood, like cedar, that naturally stands up well to moisture. Composite decking can outlast wood but is more expensive and doesn’t look as natural. Keep in mind that you’ll need to seal any exterior wood product to protect it from the elements and other forms of external damage.

A covered deck can be a good investment that increases your home value—especially if you live in a hot region with a lot of sun. A covering over the deck means you can get more use out of it, even on the hottest summer days. With a permanent deck covering, you can even add ceiling fans to help cool down your deck for added comfort.
