Yes, you can usually screen in an existing patio slab in Mandeville, as long as the slab is sound enough to anchor a frame and there’s a roof over it or room to add one. Screens alone don’t make a porch; they need a structure to hang on, so the real questions are the condition of the concrete and what’s overhead.
Mandeville has a long screened porch tradition, and with the lakefront, the bayous, and live oak shade around Old Mandeville, it’s easy to see why. We screen existing patios across Mandeville and the Northshore, and this guide covers how we decide whether a slab is ready and walks through the build, then the permit and approval questions to settle first.
Key takeaways
- A slab can carry a screen room if it’s level enough, free of major cracks, and has solid concrete where the posts will anchor.
- If the patio has no roof, the project becomes a cover plus screens, designed together.
- The City of Mandeville requires a building permit for construction, whether a company or the homeowner does the work.
- Old Mandeville addresses inside the historic district need a Certificate of Appropriateness before a building permit is issued.
