Composite decking from Trex or TimberTech is the most practical choice for Concord's hot summers. It resists heat-related expansion and contraction better than wood, does not require staining, and lasts 25 to 30 years. For homeowners who prefer natural wood, redwood with a UV-blocking finish is a good option.

A typical deck takes two to four weeks from start to finish, depending on the size and complexity. Permit review adds two to four weeks before construction begins. A simple ground-level deck may take one week. A multi-level deck with built-ins and lighting may take four to six weeks.

According to the Remodeling Magazine Cost vs. Value Report, a wood deck addition recoups approximately 50 to 60 percent of its cost at resale nationally. In the Bay Area's competitive housing market, a well-designed deck can be a strong selling point, particularly in neighborhoods like Concord's Countrywood and Dana Estates where outdoor living space is highly valued.
