Western Red Cedar (Thuja plicata) Hardwood

Both are naturally durable softwoods. Cedar (350 lbf) is softer and lighter than Cypress (510 lbf). Cedar has better dimensional stability and is more widely available nationally. Cypress heartwood may have slightly better decay resistance. Cedar is preferred for siding; both work for fencing and structures.

Cedar heartwood typically lasts 20-30 years above ground without treatment. With regular maintenance (staining every 2-3 years), it can last longer. For comparison, untreated pine lasts 3-5 years and pressure-treated pine 10-15 years.

Western Red Cedar decking/siding typically costs $3-7 per linear foot depending on grade and dimension. Premium clear grades cost more. It's moderately priced between treated pine and tropical hardwoods.

Cedar offers natural, chemical-free durability and better aesthetics. Treated lumber is cheaper and performs better in ground contact. For visible outdoor applications (siding, fencing, decking), cedar is preferred. For structural ground-contact use, treated lumber is standard.

Yes. Cedar's aromatic compounds naturally repel moths, carpenter ants, and other insects. This is why cedar is the traditional choice for closet lining and storage chests. The effect diminishes as the wood ages and the scent fades.

Ipe is 10x harder (3,680 vs 350 lbf), much denser, and lasts 75+ years vs cedar's 20-30 years. Ipe is far superior for high-traffic decking. Cedar is lighter, easier to work, and more affordable — best for covered decks, siding, and fencing where extreme durability isn't critical.
