Column posts for backyard porch

[Ben M.]

What type of lumber are installed in column posts for backyard porch. Is 20 year ground contact lumber common? What other options for lumber are available that would last longer? 

[Jay Thomas]

For backyard porch columns, pressure-treated lumber is a good pick because it’s budget-friendly and stands up to rot and insects. You might see 20-year ground contact lumber, but it’s not usually used above ground. If you want something longer-lasting, cedar and redwood are great—they handle Houston’s humidity well, though redwood is pricier. Composite materials are another option; they’re durable and low-maintenance, but they cost more initially.
