Redwood lumber is in almost every way, a remarkable decking material; it’s very stable, straight, and its heartwood is naturally-resistant to wood-boring insects and weathering without using preservative chemicals. It’s beautiful, versatile, and sustainable. When you build with this wood, you capture its natural beauty and unique properties. Not only, is the material prized for its exceptional beauty, but also for its ease-of-workability, resistance to shrinking, warping and checking. It’s been historically the most popular decking material because of these properties. Redwood may last up to approximately 30 years with a well-maintained deck under good circumstances.
