Deck Maintenance FAQs, answered by experts

Yes, designing builds to fit space constraints and meet functional needs.

Applying too much sealer to a deck might seem like extra protection, but it can cause more harm than good. Wood is a porous material with a limited capacity to absorb liquids. When you go overboard with sealer, the excess can't soak in and instead forms a film on the surface. This leftover layer is prone to peeling, cracking, and trapping moisture, ultimately defeating the purpose of sealing in the first place. 

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.

In most cases, there should be a small gap between the house and the deck, usually no more than ½ to ¾ of an inch. This space allows water and moisture to flow through instead of pooling against the side of your house. It also lets flashing protect your siding from runoff, which is one of the most common issues with decks.

What goes under your floating deck depends on your preferences. Some homeowners put landscaping fabric underneath their decks to prevent weeds from popping up through the boards. Others choose to build a floating deck over grass or gravel. However, it’s best not to set your deck directly on the ground. Instead, set your deck on blocks to keep it elevated enough to prevent moisture from rotting the wood.
