Price Ranges by Project Type
These are 2026 numbers based on actual project pricing in the Wilmington, NC area. Coastal NC pricing runs modestly higher than the NC inland average due to material specifications for salt air, humidity, and wind loads. Pricing covers labor and materials unless noted.
| Project Type | Low | High | Typical |
|---|---|---|---|
| Porch Rescreening (existing frame) | $2,500 | $6,000 | $3,500-5,000 |
| Screen Porch Repair (storm damage) | $800 | $5,000 | $1,500-3,000 |
| Porch Enclosure (convert open porch) | $6,000 | $18,000 | $8,000-14,000 |
| New Screened Porch (small, 150-250 sq ft) | $9,000 | $18,000 | $11,000-15,000 |
| New Screened Porch (medium, 250-450 sq ft) | $14,000 | $28,000 | $18,000-24,000 |
| New Screened Porch (large, 450+ sq ft) | $22,000 | $45,000 | $28,000-38,000 |
| Aluminum Screen Room (pre-engineered) | $12,000 | $32,000 | $16,000-24,000 |
| Pool Enclosure | $18,000 | $55,000 | $24,000-38,000 |
| Three-Season Room | $18,000 | $45,000 | $24,000-36,000 |
| Four-Season Sunroom | $35,000 | $90,000+ | $45,000-70,000 |
What Drives Cost in Coastal NC
Wilmington and the Cape Fear Coast have specific conditions that affect screened porch pricing differently than inland NC.
No-See-Um Mesh
Standard 18x14 fiberglass screen does not block sand gnats (no-see-ums), which are a significant problem along coastal NC from roughly March through October. Most Wilmington homeowners need 20x20 no-see-um mesh. The finer mesh costs more per roll and takes longer to install than standard screen. Budget an additional $300 to $800 over standard screen pricing for a typical-size porch.
Hurricane-Rated Hardware
New Hanover County falls in a high-wind zone under NC building code. Framing requires hurricane-rated metal connectors, proper post anchoring to footings, and connections designed to resist wind uplift. These are code requirements, not optional upgrades. They add to material costs and require more precise installation than standard construction.
Salt-Air Fasteners
Standard galvanized fasteners corrode in coastal NC within a few years of salt air exposure. We use stainless steel or hot-dipped galvanized hardware throughout. The price difference per pound of fasteners is significant, and it adds up across a full porch build. It's not a big number in the context of the overall project, but it's a legitimate cost that distinguishes a coastal build from an inland one.
Permit Fees
New Hanover County building permits for a residential screened porch typically run $150 to $400 depending on project valuation. Island municipalities (Wrightsville Beach, Carolina Beach) have their own permit processes and may involve CAMA review for coastal properties near the shoreline. Brunswick County (Leland) has a separate fee schedule from New Hanover County. All permit costs are passed through at cost.
Cost Factors That Matter Most
Size. The biggest single driver. More square footage means more framing, more screen, more roofing material, and more labor. A 400 sq ft porch costs significantly more than a 200 sq ft porch even with identical specifications.
Framing material. Pressure-treated wood is the most common framing choice for standard porches. Aluminum costs more upfront but requires less maintenance in coastal conditions. Cedar is aesthetically preferred by some homeowners but carries a premium. The framing material choice affects both the initial quote and the long-term maintenance cost.
Roofing. A screened porch with a basic aluminum or fiberglass roof panel costs less than one with a fully framed insulated roof, standing seam metal, or a cathedral ceiling. The roof often represents 25 to 35% of total project cost on a new build.
Foundation / existing structure. Building on an existing concrete slab saves significant cost compared to pouring new concrete. If there's no existing slab, add $2,000 to $6,000 for concrete work depending on size. Some projects also require footings for post anchoring, which adds cost beyond the slab.
Screen type. Standard 18x14 fiberglass, no-see-um 20x20 mesh, solar screen, and pet-resistant screen all carry different price points. Solar screen (for reducing heat and glare) can cost 30 to 50% more than standard screen.
Rescreening vs. New Build
If you have a structurally sound existing porch frame, rescreening is usually the most cost-effective option. The frame itself typically lasts 20 to 30 years with proper maintenance, while the screen panels last 7 to 15 years depending on UV exposure and use. A rescreen runs a fraction of the cost of a new build and extends the life of your existing structure.
When to consider a full rebuild instead: significant wood rot in the framing, posts that were never properly anchored to footings (a hurricane risk that inspectors flag), or an existing structure that can't be adapted to current code requirements. We assess all of these on the free estimate visit.
Getting an Accurate Quote
Phone estimates for screened porches are guesses. There are too many variables - existing foundation conditions, local soil, roof pitch, permit requirements for the specific municipality - to give you a real number without seeing the site. We give free on-site estimates throughout Wilmington and the Cape Fear Coast. The estimate includes a written scope of work and pricing so you can make an informed decision before committing.
