For those who prefer the look and feel of real wood, Redwood is the way to go.
It is naturally resistant to wood-boring insects and weathering without the use of preservative chemicals. Redwood can last up to about 30 years on a well-maintained deck under good circumstances and is the most fire-resistant decking material on the market.
Historically, Redwood has been the most popular deck material because of these properties. However, because of a limited supply and environmental concerns, it is now less available and can sometimes be more expensive than composite decking material. One must also weigh the cost and time needed to properly care for their wood decks. There is the need for seasonal painting, staining, and/or sealing, and depending on the grade of wood chosen, fading, staining, splits and splinters can be an issue.
