What a Full Screened Porch Installation Involves
A screened porch installation is more than stapling screen to a frame. For a Wilmington home, you're looking at foundation work, structural framing that meets NC coastal wind-load requirements, proper permitting through New Hanover County, and screen selection that actually keeps the bugs out. We've built porches across Wilmington, Leland, Hampstead, Wrightsville Beach, and the rest of the Cape Fear Coast, so we know what the inspectors want to see and what the climate will put your porch through.
The basic sequence: site assessment and measurements, permit application, foundation or slab prep, post and beam framing, roofing or roof tie-in, screen framing and installation, finishing, and final inspection. Projects typically run 2-4 weeks from permit approval, depending on size and complexity.

On-Slab vs. New Concrete Pour
If your home already has a patio slab in good condition, we can often build directly on it. We'll check the slab for cracks, slope, and thickness first. Most existing slabs in Wilmington neighborhoods are 3.5-4 inches, which is workable. Posts get set with anchor bolts drilled and epoxied into the concrete.
If you're starting from bare ground, we pour a new slab. In New Hanover County, a slab for an attached structure needs to be at the correct frost-depth setback and must drain away from the house. We grade, form, and pour, then wait for the concrete to cure before framing begins. On sandy soils common near the coast, we sometimes install a vapor barrier and additional base prep to reduce moisture wicking up through the slab.
For raised decks at Wrightsville Beach or Carolina Beach properties, we can also build over an existing deck structure if the framing is sound, using deck screws and hurricane ties rated for coastal exposure.
Hurricane Wind Loads and Coastal Construction Requirements
Wilmington sits in a high-wind zone. The NC Residential Code and ASCE 7 wind maps place most of New Hanover County at 130-140 mph design wind speeds, with properties closer to the water pushed even higher. That means your screened porch frame has to be engineered accordingly, not just built to standard residential spec.
For attached porches, we use hurricane ties at every rafter-to-beam connection and post-base connectors anchored to the slab. Knee bracing is added at corners. The ledger board connection to the house requires lag bolts into the rim joist at specified intervals, and that connection gets inspected before we close up the walls. Freestanding porches need deeper footings and moment-frame connections.
We pull all required permits through New Hanover County Building Inspections. The process involves a building permit application, site plan showing setbacks, and sometimes a zoning compliance review if you're in a flood zone (Zone AE is common near the Cape Fear River and marsh areas). Plan on 2-4 weeks for permit approval in most cases, though it can run longer during busy seasons.
Screen Selection for the Cape Fear Coast
Standard 18x14 fiberglass screen keeps mosquitoes out but does nothing for no-see-ums, the tiny biting midges that swarm near marshes, tidal creeks, and any standing water. If your property is anywhere near the Cape Fear River, Masonboro Sound, Bradley Creek, or similar areas, you want no-see-um mesh, which runs 20x20 or finer. It reduces airflow slightly but makes a real difference in usability during warm months.
For salt-air durability, we recommend fiberglass screen over aluminum. Aluminum screen corrodes faster in the coastal environment. Fiberglass won't rust and holds up well in UV exposure. Pet-resistant screen is available if you have dogs or cats that like to push on the screen panels. We'll walk you through the options and trade-offs before we order materials.
We serve all of the greater Wilmington area, including Leland, Hampstead, Castle Hayne, Ogden, Porters Neck, Holly Ridge, Jacksonville, Surf City, and both beach towns.
Cost Ranges for Screened Porch Installation in Wilmington
A straightforward screened porch on an existing slab, 12x16 feet with basic pressure-treated framing and standard screen, runs roughly $9,000-$14,000 installed in Wilmington. Mid-range projects with a new slab, cedar or composite framing, ceiling fan rough-in, and no-see-um mesh typically land between $15,000-$24,000. Larger porches, premium materials, hip roofs, or builds on raised foundations at beach properties can reach $30,000-$35,000 or more. Permit fees in New Hanover County add $300-$600 depending on project value.
