Why this fits you

\n
  • You want natural rot resistance without chemical treatment.
  • A warmer, more refined look than PT pine appeals to you.
  • You\'re willing to pay a moderate premium over PT pine.
\n

Cedar decking offers natural rot and insect resistance along with a warmer color and finer grain than typical PT pine, without chemical treatment. It costs more than PT decking but less than premium hardwoods or high-end composite. Like PT decking, it benefits from periodic sealing to maintain its color, though its natural oils provide real protection even left unfinished.

Buying checklist

\n
  • Seal periodically if you want to maintain cedar\'s natural color rather than let it weather to gray
  • Softer than PT pine -- more prone to denting under heavy furniture or foot traffic
  • Confirm you\'re getting genuine Western red cedar rather than a lower-durability substitute sold under a similar name

Frequently asked questions

\n
Does cedar decking need sealing like PT decking?

For color retention, yes -- though its natural oils provide real rot resistance even unfinished, letting it weather to a silver-gray if you don\'t mind that look.

Is cedar decking as durable as PT pine?

It\'s naturally rot-resistant and performs well, though it\'s generally softer and more prone to denting than PT pine under heavy use.

Why choose cedar over PT pine for decking?

Primarily for its warmer natural appearance and avoiding chemical treatment -- functionally both offer solid decking performance, so the choice often comes down to look and budget.
