A deck is an extension of your home's living space. It offers extra room for dining, entertaining, and relaxing in the sun (or shade). Decks need little maintenance and few repairs to keep them in good condition. Here's how to take good care of your home's deck.

How Does It Work?

Components of a typical deck.

A deck is a flat structure adjoining a house. It consists of a floor, horizontal joists, horizontal beams, and vertical posts. In addition, a deck typically has perimeter railings and stairs. Decks are constructed of decay-resistant wood (redwood, cedar), pressure-treated wood, or newer plastic materials, and are held together with fasteners.

What Can Go Wrong?

From exposure to the weather, a deck's protective finish will deteriorate and need renewing. Boards warp and sometimes are damaged. The edges of deck boards may become rough and unsightly. Steps may be damaged. Parts can loosen up.
