Screened-In Porch Cost Calculator

A screened-in porch typically costs $5,000 to $25,000, with most projects landing around $8,000 to $18,000 — but the range is wide because it depends entirely on scope. Simply screening in an existing covered porch can be $2,000 to $6,000, while building a new, large, or premium screened porch can top $25,000 to $40,000+. On a per-square-foot basis, that's about $25/sq ft to screen an existing porch, ~$75/sq ft to build a new standard porch, and ~$120/sq ft for a premium build. The main drivers are the porch size, whether you're screening an existing structure or building new (the biggest factor by far), the screen system (standard fiberglass vs. premium pet/solar/no-see-um vs. motorized), and the roof. Add-ons like a foundation/deck, upgraded flooring, a knee wall, electrical, a ceiling fan, and a screen door add on top. A ~$1,500 project minimum applies. Enter your details above for a localized estimate.

It's dramatically cheaper to screen in an existing covered porch — often a fraction of the cost of building new — because the expensive parts (foundation, floor, posts, and roof) already exist. Screening in an existing porch mostly means adding screen framing and mesh between the existing posts plus a screen door, so you're paying for screening and labor, typically $2,000 to $6,000 (roughly $25/sq ft here). Building a new screened porch from scratch means constructing everything — footings, a floor/deck, framing, a roof (a major cost), and then the screening — which runs $15,000 to $30,000+ (about $75–$120/sq ft). The structure, especially the roof and foundation, is where most of the money goes, so the more sound existing structure you can reuse, the less you spend. If you have a covered porch, screening it in is by far the most cost-effective route; build new only if you don't have suitable existing structure. This calculator includes both paths.

The core difference is the enclosure: a screened porch uses insect screen (open-air), while a sunroom uses glass (enclosed and weather-tight). A screened porch keeps out bugs, leaves, and debris while letting in fresh air and breezes — it's the most affordable enclosure and gives the most 'outdoor' feel, but it isn't weather-tight (rain can blow in) and isn't heated or cooled, so it's mainly seasonal, fair-weather use. A sunroom is glassed in and can be climate-controlled: a '3-season' room without full HVAC, or a '4-season' room with heating and cooling for year-round use. Sunrooms cost more (glass, more construction, possibly HVAC) and feel more like an interior room than an open porch. A patio enclosure is a broader term that can be screen, glass, or a convertible system. Choose a screened porch for affordable, open-air, bug-free living in nice weather; a sunroom if you want a weather-protected, longer-season room with light and views.

Standard fiberglass screen is the best all-around choice for most porches — it's affordable, flexible, won't corrode or crease, and gives good insect protection and visibility, which is why it's the default. From there you upgrade for specific needs: pet-resistant screen (a heavy, vinyl-coated polyester) resists scratching and pushing from dogs and cats; solar/sun-control screen blocks a portion of the sun's heat, glare, and UV to keep the porch cooler and reduce fading (great for west- and south-facing porches in hot climates); and no-see-um/fine mesh has a tighter weave that keeps out the tiniest biting insects like gnats and sand flies (worth it near coasts and marshes, though it reduces airflow a little). Aluminum screen is more durable but can dent. Motorized retractable screens aren't a mesh type but a system that opens the porch fully and deploys screens when wanted — the premium, flexible option. This calculator groups the pet/solar/no-see-um upgrades as a premium screen and offers motorized separately.

Usually yes for a new build, and possibly even to screen in an existing porch — so check with your local building department before starting. Building a new screened porch is new construction of a roofed structure with a foundation and framing attached to the house, which almost always requires a building permit and inspections to confirm it meets structural, roofing, attachment, and (if added) electrical codes. Screening in an existing covered porch is less clear-cut: if you're only adding screen framing and mesh with no structural changes, some jurisdictions don't require a permit while others do — and the moment you add electrical (outlets, lighting, a ceiling fan) or modify the structure, a permit becomes much more likely. Permits matter because unpermitted structures can cause fines, forced removal, insurance problems, and complications when you sell. Also check zoning setbacks and HOA rules, since a porch must sit within property setbacks. A reputable contractor typically pulls the permits and handles code compliance; budget a bit of time and modest fees for it.

Yes — a screened-in porch generally adds value and is a sought-after feature, because it extends the home's usable living and entertaining space into a comfortable, bug-free outdoor area that buyers appreciate. The value is highest in warm, humid, or insect-prone regions (the South, Southeast, and Midwest summers), where outdoor living with insect protection is especially prized and the usable season is long; in cold climates with short outdoor seasons the added value is somewhat lower but still real. Like other outdoor-living projects, a screened porch tends to return a solid portion of its cost at resale, with the exact ROI depending on the quality of the build, how well it integrates with the home's style, its size and usability, and local buyer preferences. Beyond resale, much of its worth is the personal enjoyment — years of comfortable outdoor relaxing and entertaining. To maximize value, build a quality, well-designed porch suited to your climate, keep it permitted and code-compliant, and add comfortable features like a fan and lighting.

The features that make a screened porch genuinely usable are usually worth the modest cost. Electrical and outlets (~$800) power everything else and let you use the space in the evening and plug in fans, chargers, and a TV. A ceiling fan with lighting (~$600) is one of the highest-value additions — the fan keeps the porch comfortable on hot, still evenings and also helps keep insects moving off, while lighting extends usable hours after dark. A screen door (~$350) is essential for access without letting bugs in. Beyond comfort, a foundation or deck base (~$2,000) is needed if you don't already have a floor, upgraded tile or composite flooring (~$1,500) gives a finished look and durability, and a knee wall or half wall (~$1,000) below the screens adds structure, a place to lean, and a more finished appearance. Prioritize electrical, a fan with lighting, and a screen door for comfort; add the structural upgrades based on your build and budget.

It depends heavily on the scope. Screening in an existing covered porch is quick — often just a few days to a week, since it's mainly installing screen framing, mesh, and a door on a structure that already exists. Building a new screened porch from scratch takes much longer, typically 2 to 4 weeks, because it involves the full construction sequence: footings and foundation, the floor or deck, posts and framing, the roof, and then the screening and any electrical and finishes. Larger porches, complex or cathedral roofs, premium finishes, and added features all extend the timeline, as do permitting and inspection steps (which happen before and during construction) and weather, since much of the work is outdoors. A motorized screen system adds installation time too. Your contractor can give a firm schedule once the design, scope, and permits are set — plan for a few days for a simple screen-in and several weeks for a new build.
