Is cypress more rot-resistant than cedar?

Old-growth cypress heartwood is exceptionally rot-resistant. Modern second-growth cypress and cedar are roughly comparable in decay resistance.

Can I get cypress outside the Southeast?

Yes, but availability is limited and prices are higher. Cedar is usually the more practical choice for Northern and Western projects.

Which is better for a dock?

Cypress has a long history in dock and marine construction in the South. Its density and moisture tolerance make it well-suited for water-adjacent structures.

Does cypress need to be sealed?

Like cedar, cypress benefits from periodic sealing to maintain its natural color. Left untreated, it weathers to a silver-gray patina.
