How Much Does a Full Deck and Screened Porch Build Cost?

Screened Porch & Deck Screening Cost Guide for Brevard & Indian River County (2026)

Screening in an existing covered porch or deck is the more affordable option, typically ranging from $2,800 to $12,500, or approximately $28–$35 per square foot, depending on the layout and screen options. Building a brand-new screened porch with its own roof is a true construction project, generally ranging from $18,000 to $65,000+, depending on the size, roof style, engineering requirements, and finishes.

This guide breaks down real pricing factors for our area, including the coastal engineering that makes Brevard and Indian River County projects different from the national averages you'll see elsewhere.

Quick Answer: Cost by Project Size

Every project is quoted to the actual space — the price ranges can help frame the conversation, and an on-site measure settles it.

The One Factor That Matters Most: What You're Starting With

Screening an existing covered porch, lanai, or deck. The roof and structure already exist, so you're paying for aluminum framing, screen, a door, and labor. This is the budget-friendly path — see our patio enclosure service for exactly this project.

Building new. No roof means building one — framing, roofing, engineering, and a foundation or verified footings, then the screens. It's a genuine construction project with permits and engineered drawings, which is why the price is a multiple of the screening-only route.

The in-between case that surprises people: a deck with no roof. Adding a roof to an existing deck isn't a small upgrade — a roof system puts significant load on the structure below, and many decks were never built to carry it. Part of any honest quote is assessing whether your deck's framing and footings can take the weight; if not, new footings or a slab change the scope. We'd rather tell you that at the estimate than discover it mid-project.

What Moves the Price in Brevard & Indian River County

  • Square footage — the primary driver; more area, more material and labor.
  • Coastal engineering — this is the line that separates local costs from national averages. Our projects are engineered and permitted to the Florida Building Code wind-load for your location — higher near the coast — with anchoring to match. [If you quote a typical coastal-engineering premium, state your real figure; otherwise describe it qualitatively.]
  • Salt-air materials — powder-coated aluminum framing and corrosion-resistant hardware cost more than bare builder-grade material and are non-negotiable near the water; wood framing rots, twists, and feeds termites in our humidity, which is why we build in aluminum.
  • Roof style (new builds) — a gabled/peaked roof costs more than a flat or shed roof [your real delta].
  • Mesh choice — see the table below.
  • Electrical — ceiling fans, lights, and outlets [your real per-fixture pricing].
  • Doors and steps — screen door options and any stairs/railings to code.
  • Permits and engineering — county or municipal permits plus engineered drawings [your real range]; some lots also need a survey to verify setbacks.
  • Site condition — demolition of an old structure, hidden rot where the old deck met the house, soil and footing needs.

Where the Surprise Costs HJide

Budget a contingency of [10–15% — confirm you agree with this guidance] for the things that only show up once work starts: unstable soil under planned footings, rotted wood where the old structure attached to the house, water damage behind missing flashing. Tear-out of an old deck plus debris hauling is its own line item [your real range]. None of this is unusual — it's why our quotes itemize and why we look hard at the attachment points during the estimate.

Why Quotes Differ so Much Between Contractors

Two bids for "the same porch" can be thousands apart because they aren't for the same porch. A low bid often covers screen installation only, on the assumption your structure needs nothing; a complete bid includes engineered drawings, permits, code-compliant anchoring, coastal-grade materials, and debris removal. Before comparing numbers, compare scope: Are permits and engineering included? Is the material powder-coated aluminum? Who handles demolition and haul-away? Does the price meet the wind-load code for your address — and will it pass inspection? A quote that skips those isn't cheaper; it's incomplete.

Ways to Keep the Budget in Check (honestly)

  • Build on what you have. A sound existing slab or covered lanai eliminates the most expensive line items. (That's the patio enclosure path.)
  • Keep the footprint rectangular. Simple layouts frame and roof faster than multi-angle designs.
  • Choose electrical deliberately. A fan and a couple of outlets serve most porches; elaborate lighting plans add real cost.
  • Combine projects. If you're considering two outdoor projects, one mobilization and one permit round costs less than two.
  • Don't cut the engineering. The place not to save is wind-load compliance and anchoring — it's the difference between a porch and storm debris, and it's required to pass inspection anyway.

A screened porch is also one of the outdoor projects that genuinely reads as value at resale in Florida — protected, usable outdoor space in a climate where bugs and sun otherwise claim it.

Frequently Asked Questions

How much does it cost to screen in an existing covered porch or deck?

Approximately $28–$35+ per square foot. The structure being already in place is what keeps this the affordable version of the project.

How much does a brand-new screened porch cost?

$10,000 to $15,500+, driven by size, roof style, foundation needs, and features. It's a permitted construction project with engineered drawings — built once, to code, for our wind.

What does a 12×12 / 12×16 / 20×20 screened porch cost?

See the size table above.

Can my existing deck support a screened porch roof?

Maybe — that's the first thing we assess. Roof systems load the structure below, and many decks weren't built for it. If yours can't carry it, new footings or a slab join the scope; we'll tell you at the estimate, not after demolition.

Do I need a permit?

Yes — screened porches in Brevard and Indian River County are permitted structures with engineered drawings and inspection. We handle the permitting end-to-end, and the cost is itemized in your quote.

Why is the coastal version more expensive than national averages online?

Because national averages don't include Florida wind-load engineering, hurricane-rated anchoring, or salt-air-grade materials — and around here, quotes without them don't pass inspection.

The Bottom Line

Screening an existing covered space is the high-value move — modest cost, immediate payoff. Building new is a real construction project priced accordingly, and in this county it's engineered for wind and salt or it isn't worth building. Either way, the honest number comes from a measure and an itemized quote, not a national average.
