Would cypress be a good choice for a porch we're adding in front of our house?

We have used cypress for a fence over 30 years ago, and it still has no sign of rotting or mildew.

Dear J Browon,

As for your 30 year old fence, its success in not succumbing to rot may be due, in part, to the finish applied to it at the time of install.

Never the less, Cypress is a good wood choice for decking material due to its ability to withstand the degradation of moisture.

You can find salvaged/reclaimed Cypress as well as virgin harvested Cypress; check with your local suppliers.

A few things to consider:

  • recommended moisture content is 10-12%,
  • for decking use Grade #2 or Select and
  • choose boards that are 6” wide or less to minimize cupping.

Good luck!
