Cedar, redwood, cypress and other naturally rot-resistant woods are often hailed as the premier choice when building outside structures like decks, arbors or saunas. They have beautiful color and grain, are often aromatic, and their chemical structure can make them immune to insect and fungal pests.  

However, naturally resistant wood species are not guaranteed to last any longer than pressure- or green-treated lumber. Here are some ways to help ensure your natural, beautiful and expensive wood lasts for decades, not years.
