Installing Composite Deck Skirting and Fascia
Deck skirting can be an attractive feature that can be added to any low-level deck. You can use boards to construct a wall around the bottom of your deck. Another option is to use wood or vinyl lattice material. Make sure you leave gaps for ventilation to prevent mold from growing under the deck. You should install a door for access to under the deck. This area can be used for storage. You shouldn't anchor the skirt to the ground because frost heave will eventually damag the skirt. Constructing a deck skirt will require a lot of additional material depending on the height of the deck. Typically, lattice is sold in 4' x 8' sheets. There is also considerable added labor involved.
Most contractors use some type of fascia to finish the edge of the deck and hide the underneath support joists. Many brands of decking actually offer fascia that will match the deck boards. However, if you are looking for a nice contrast in your deck design, you may want to opt for a fascia of cellular PVC. Low maintenance cellular PVC is available in board and sheets and comes in smooth or textured finishes. Cellular PVC products come in white but can be painted, if desired.
