The Advantages and Disadvantages of Redwood Decks

Appearance

• Many homeowners choose redwood for outdoor decks for its appearance. It is available in varying shades of red and pink that blend with the natural outdoor surroundings. Redwood has a straight grain that is easy to cut. If left unfinished, the wood will weather to a natural gray shade, but it can be stained and sealed to keep the natural wood finish if you prefer.

Durability

• Although oak and maple are harder woods, redwood is durable and resists shrinking and warping. It has natural tannins that deter rotting from weather and insect damage. With regular maintenance, redwood can be expected to last for 20 years or more. As with any wood, redwood can be damaged by water over time, but it resists such damage longer than other woods. If you choose sapwood, the wood that closest to the bark, this is less durable and more susceptible to rot, however.

Maintenance

• Although redwood is a durable wood, it does require regular cleaning and maintenance in order to stay in the best condition, which is a disadvantage when compared to composites. The wood should be cleaned and treated with a water-repellent finish every year to protect it from weathering and UV damage. Redwood resists rotting from weather, but just as with any wood, it is important to keep water from pooling on the boards. Redwood boards are available with a slight crown on the top surface, which encourages water to drain away.

Cost

• Redwood is more expensive than other natural wood choices, including pressure-treated wood and plastic composites. The advantages in appearance, durability and longevity may outweigh cost considerations for some. Construction-grade redwood is a less expensive option with the same durability as better grades. It has a lot of tight knots, however, and lacks the sought-after appearance of the more expensive grades
