How Much Does a Screened-In Porch Cost in Maryland? (2026)
It's the first question almost every homeowner asks, and it's one of the harder ones to answer honestly — because "screened porch" covers a huge range of projects, and the price range reflects that.
A basic screened porch conversion over an existing concrete patio is a very different project from a new ground-up build with a gable roof, composite decking, and custom screen doors. Both are "screened porches." The price difference between them can be $20,000 or more.
Here's a straight breakdown of what drives cost in the Anne Arundel and Howard County market, what you can expect to pay at different project scales, and where the money actually goes.
The Short Answer
For a screened porch in Maryland, here's a realistic range by project type:
| Project Type | Typical Range |
|---|---|
| Basic enclosure over existing slab | $12,000 – $22,000 |
| New build, pressure-treated frame, shed roof | $22,000 – $38,000 |
| New build, gable roof, composite decking | $35,000 – $55,000 |
| Premium build with EZE-Breeze or custom details | $50,000 – $75,000+ |
These are contractor-installed, permitted project costs in the current Anne Arundel and Howard County market — not DIY estimates, not kit prices from a home center. Material and labor costs in this region run higher than national averages, and permit fees, inspection requirements, and engineering add to the baseline.
What Drives the Cost of a Screened Porch
Five factors move the number more than anything else.
1. Foundation and floor system
If you have a solid, level existing concrete patio in the right location, that's the lowest-cost starting point. You're building up from something that's already there. If the slab is cracked, unlevel, or in the wrong spot, you're either repairing it or pouring new concrete — which adds $3,000–$8,000 depending on size and site conditions.
A raised deck frame instead of a slab adds cost but gives you more flexibility on sloped lots and allows for drainage beneath the structure. Expect to add $8,000–$15,000 over a slab-based build for a comparable footprint.
2. Roof structure and complexity
A simple shed roof — sloping away from the house in one direction — is the most cost-effective option. A gable roof that peaks in the middle adds framing complexity and cost. A hip roof is more involved still.
Beyond shape, the roof material matters. Architectural shingles to match your existing house, standing seam metal, or polycarbonate panels all carry different price points. Matching your home's existing roofline almost always adds cost but has a real impact on curb appeal and resale value.
Roof structure is also where engineering sometimes gets required. If the porch is large, if the roof load transfers to an existing deck frame, or if the jurisdiction requires stamped drawings, you'll have engineering costs on top of construction.
3. Porch size
Screened porches are most commonly quoted by the square foot, and size is the most straightforward cost driver. A 200 sq ft porch and a 400 sq ft porch don't cost twice as much — there are shared fixed costs in permitting, mobilization, and structural work — but size is still the primary lever on total project cost.
Most Anne Arundel and Howard County homeowners build in the 200–400 sq ft range. Anything under 150 sq ft starts to feel cramped for furniture and real use. Anything over 500 sq ft starts to require more attention to structural engineering and drainage.
4. Screen and door system
Standard fiberglass screen and vinyl-framed doors are the cheapest option. They're also the most likely to need replacement within a few years — which is why we don't use them.
PRG installs Super Screen vinyl-coated polyester mesh and aluminum-framed screen doors on every porch build. The material cost difference over a standard fiberglass-and-vinyl setup is a few hundred dollars on a typical project. The performance difference over a 10-year horizon is significant — you're not re-screening, and your doors aren't sagging. On a project that might cost $35,000 total, it's not where you want to save money.
If you want EZE-Breeze vinyl glazed panels for three-season flexibility, plan for an additional $3,000–$8,000 depending on the number of openings.
5. Finish level
Pressure-treated framing with basic trim is the starting point. From there, every upgrade adds cost: composite or PVC trim on exposed surfaces, tongue-and-groove pine or cedar ceiling, recessed lighting, ceiling fans, built-in benches, outdoor-rated electrical outlets. These aren't frivolous additions — they're the difference between a porch you use daily and one that sits empty because it's not quite comfortable enough.
Electrical is worth calling out specifically. Running a dedicated circuit for ceiling fans and lighting during the build is far cheaper than adding it after the fact. Budget $1,500–$3,500 for basic electrical depending on panel access and how many fixtures you're adding.
What the Money Actually Pays For
Homeowners sometimes look at a screened porch quote and think about what they could buy with the same money. It's worth being clear about what you're actually getting.
Labor is the largest line item on most porch projects. Framing a roof structure, properly flashing it where it meets the house, building a code-compliant floor system, installing screen panels that are tight and straight — this is skilled work. The connection between the porch roof and your house's existing structure is the most important detail on the entire project. Done wrong, it leaks. Done right, it's watertight for decades.
Permits and inspections add to the cost and timeline, but they're not optional in Anne Arundel or Howard County — and they're not a bad thing. A permitted structure was inspected at key stages of construction. That matters when you sell the house.
Materials in the current market are higher than they were three years ago. Lumber, connectors, roofing materials, and hardware have all held at elevated prices. What something cost in 2021 or 2022 isn't a useful benchmark for 2026 pricing.
What Not to Do on a Budget
If cost is a real constraint, here's where to spend and where to trim:
Don't cut on the roof and structure. This is the part of the project that protects everything else. A well-built frame with a properly flashed roof connection lasts decades. A rushed frame with cheap flashing leaks, rots, and eventually fails.
Don't cut on the screen system. Re-screening a porch costs $500–$1,500. If you build with cheap fiberglass and replace it twice over 15 years, you've spent more than the upgrade would have cost at the start.
Do trim on finishes if needed. Pressure-treated framing and a simple painted ceiling instead of tongue-and-groove is a reasonable trade-off. You can add finish upgrades later. You can't rebuild a bad roof without tearing everything apart.
Do build the size you actually want. Homeowners who build too small almost always wish they'd gone bigger. Adding onto a screened porch after the fact is expensive — the roof structure has to be extended, permits re-opened, and the seams need to be detailed carefully. Build the right size once.
Does a Screened Porch Add Value in Maryland?
Yes — consistently, in this market. Outdoor living additions perform well at resale in Anne Arundel and Howard County because buyers understand what they're buying: usable outdoor space in a climate where bugs and heat make open decks uncomfortable for months at a time.
A screened porch also photographs well and shows well. It's a feature buyers remember. That matters in a market where most homes compete on square footage and kitchen finishes.
A rough rule of thumb: a well-built screened porch recovers 50–75% of its cost at resale, with higher recovery on well-designed additions that match the home's architecture. That's not a guarantee, and it varies by neighborhood and buyer pool — but it's a real value addition, not just a lifestyle one.
Why Do Screened Porch Quotes Vary So Much Between Contractors?
Because scope varies. One contractor may be quoting over your existing slab; another may be including a new concrete pour. One may be using fiberglass screen and vinyl doors; another is pricing aluminum doors and quality mesh. Before comparing quotes, confirm exactly what's included — foundation work, permit fees, screen system, electrical, and finishing details. A lower quote is often a narrower scope.
Is a Screened Porch Cheaper Than a Sunroom?
Significantly. A sunroom is a fully enclosed, climate-controlled addition with insulated glass panels and HVAC integration. Expect to pay $60,000–$120,000+ for a quality sunroom in this market. A screened porch is open to the air and unheated — that's what makes it more affordable and also what makes it a three-season space rather than four.
Can I Get a Screened Porch Built This Summer?
If you start the conversation now, yes — depending on current project schedules. Permit timelines in Anne Arundel County run two to four weeks. Factor in design time, material lead times, and scheduling, and starting the process in early spring typically gets you a finished porch by early summer.
Do I Need to Finance a Screened Porch?
PRG doesn't offer in-house financing, but many homeowners use home equity lines of credit or home improvement loans for projects in this range. We can provide detailed estimates suitable for financing applications.
What's the Most Common Thing Homeowners Wish They'd Done Differently?
Built it bigger. Almost universally. The second most common: added electrical from the start instead of retrofitting it.
