A screened-in porch in Metairie can cost a few thousand dollars if you’re screening a patio that already has a sound roof, or well into five figures if the porch and its roof are being built new along with the screens. HomeAdvisor’s June 2026 guide puts screening an existing porch at $5 to $20 per square foot and a new screened porch at $25 to $120, while HomeGuide’s February 2026 guide runs higher at $10 to $25 and $50 to $175, and the spread between those numbers comes down to a handful of decisions you can make before anyone hands you a quote.
We build and screen porches across Metairie and the rest of Jefferson Parish, so this guide walks through what those national figures cover, what moves a Metairie price up or down, and how to compare quotes once they arrive. Every dollar figure below comes from a named national source, and your own written estimate is the only number that applies to your house.
Key takeaways
- HomeAdvisor’s cost guide, updated June 2026, lists $5 to $20 per square foot to screen an existing porch and $25 to $120 per square foot to build a new screened porch.
- HomeGuide’s guide, dated February 2026, runs higher: $10 to $25 per square foot to add screens and $50 to $175 per square foot for a new screened porch.
- The biggest single cost driver is whether you already have a roof over the space.
- Screen type, doors, electrical work for fans and lights, and the condition of the slab all change the total.
