Screen Porches Designed for the Lowcountry
A screen porch is the most-used room in a Lowcountry home for half the year, and the least-tolerant of shortcuts the rest of the time. At Global Finishes, we build, convert, and repair screen porches throughout Savannah, Bluffton, Hilton Head Island, Pooler, Richmond Hill, and Beaufort. Whether you want a new screened-in addition off the back of the house, you want to convert your existing deck, or your current porch is sagging and your screens are torn, we handle the full job from permitting through final paint.
What makes a screen porch work in our climate is not glamorous. It is pressure-treated framing rated for the moisture load, fasteners that will not corrode in salt air, no-see-um mesh that stops the midges along with the mosquitoes, a roof pitched to shed heavy summer rain, and a ceiling fan to move the humidity out from under the roof. Get those right and your porch lasts twenty-plus years. Skip any one of them and you are tearing it apart in five. We have seen both outcomes on jobs we were called in to fix, and we build with the long view in mind.
Types of Screen Porches We Build
New Screen Porch Construction
A from-scratch screen porch starts with concrete footings sized for the local code, pressure-treated posts and beams, a roof framed and shingled to match your existing house, and screen-wall framing on all open sides. We can match your home's siding, roofline, and trim profile so the new porch looks like it was always there, not like a tacked-on box. Most ground-up porches in Savannah and Bluffton run between 200 and 400 square feet, big enough for an outdoor dining table and a separate seating area without dominating the yard.
Pressure-Treated Wood Frame Screen Porches
Pressure-treated southern yellow pine is the traditional and still the most cost-effective framing material for Lowcountry porches. We use ground-contact-rated PT lumber for any post or framing within six inches of the deck surface, and we predrill every fastener point to prevent splitting in the dense PT grain. All hardware is hot-dipped galvanized or stainless steel, never electroplated. Electroplated fasteners react with the chemicals in modern PT lumber and corrode within a year or two near the coast.
Aluminum-Frame Screen Rooms
For homeowners who want a cleaner, more modern look or who do not want to repaint wood every few years, we install aluminum-frame screen rooms. Aluminum framing is lighter, will never rot, will never need paint, and accepts screen panels that snap into place for fast replacement. It is a strong choice for second-story screen porches over garages or for any application where weight on the existing structure is a concern.
Deck-to-Screen-Porch Conversions
If you already have a deck that is sturdy but underused, screening it in is one of the highest-return projects you can do. The deck surface becomes a usable shaded room you can sit in at dusk without getting eaten alive. We assess the existing footings and joists first, reinforce anything questionable, and then frame walls and a roof over the existing platform. Most conversions take 1 to 2 weeks of on-site work and cost a fraction of building from scratch.
Screened-In Deck Conversions with Composite Decking
For deck conversions where the existing decking boards are weathered or rotting, we often replace the deck surface at the same time using composite decking. Composite holds up to salt air, never needs sealing, and will not splinter under bare feet. Brands like Trex, TimberTech, and Fiberon all perform well in our climate. We can also leave structural framing intact and only replace the visible deck boards if the joists are sound.
Gable-Roof vs. Flat-Roof Screen Porches
Roof style is one of the first decisions on a new porch and it changes everything else. A gable-roof porch with an exposed cathedral ceiling feels open and bright, ties cleanly into a house with a steeper roof pitch, and gives you room for a fan that hangs low without bumping your head. A shed-roof or flat-roof porch is simpler, less expensive, and works better when the porch tucks under an existing eave on a single-story home. We walk you through the trade-offs against your roofline before we draw anything up.
Hurricane-Rated Framing
Coastal Georgia and South Carolina sit in a hurricane-prone zone, and our local building codes reflect that. New screen porches are framed with hurricane straps, hurricane clips at every rafter-to-top-plate connection, and properly sized posts and footings to resist uplift. This is not optional and we do not skip it to save a few dollars. A porch that flies off in a Category 1 storm damages the main house when it goes. Done right, the porch stays put.
Motorized Retractable Screens
For homeowners who want the option of opening up the porch to the breeze on perfect days, or closing it to the bugs on bad ones, motorized retractable screens are a great upgrade. The screen rolls up into a discreet housing at the top of the opening when you do not need it and rolls down with a remote or wall switch when the bugs come out. They work especially well on the large openings that face the marsh or the water.
Screen Replacement & Repair
If your existing porch frame is sound but your screens are torn, sagging, or full of pet holes, we re-screen the whole porch in a day or two. We pull the old spline, clean the channels, install fresh mesh tensioned to the right tautness, and lock it down with new spline. We can swap regular fiberglass for no-see-um mesh at the same time without rebuilding anything. Most full re-screens on a 250 square foot porch run between $400 and $900 depending on panel count and mesh choice.
Lowcountry Bug Protection: It Has to Be No-See-Um Mesh
The single most common complaint we hear from homeowners with older screen porches in this area is "I still get bit." That almost always traces back to the screen mesh. Standard fiberglass screen has an 18x16 weave that was designed to stop mosquitoes and it does. But the no-see-ums (also called sand gnats, midges, or punkies) that swarm at dusk along the marshes from Tybee to Hilton Head are small enough to walk right through that weave.
The fix is no-see-um mesh, which uses a tighter 20x20 weave or finer. It costs slightly more per square foot, it cuts visibility through the screen by maybe ten percent, and it is the only thing that keeps those bugs out. We default to no-see-um mesh on every Lowcountry porch we build unless a customer specifically asks for regular screen. We have never had a customer ask us to go back the other way after sitting on a no-see-um porch at dusk.
Common Add-Ons We Build Into the Porch
Tongue-and-Groove Ceilings
A tongue-and-groove pine ceiling is the single biggest upgrade you can add to a screen porch for the money. It hides rafter undersides, gives the porch a finished interior look, and works with stain or paint. Cypress and southern yellow pine T&G both perform well outdoors when sealed properly. Painted haint blue ceilings, the traditional Lowcountry choice, look right at home on any porch from Beaufort to Savannah's historic district.
Exposed Beams
Exposed beams give a porch architectural weight, especially under a gable roof. We can leave the structural ridge and rafters exposed with a sanded and stained finish, or wrap them in finish material for a cleaner look. Cedar wraps look great in beach communities like Hilton Head and Tybee, while painted poplar fits better with the trim profiles of older Savannah homes.
Outdoor Lighting and Outlets
Most of our clients want at least a couple of switched lights and two or three GFCI outlets on the porch. Recessed cans give clean overhead light, while pendants over a dining table add warmth. Switched ceiling fan circuits are standard. Outlets for a TV, a string-light controller, or a slow cooker for game-day cookouts come up on almost every project. We coordinate electrical with licensed electricians under permit.
Ceiling Fans for Humidity
In the Lowcountry a ceiling fan turns a screen porch from "occasionally usable" to "the favorite room in the house." We install only wet-rated or damp-rated fans (not interior fans) and we frame in fan-rated braced boxes during construction so the fan mounts into solid blocking. For porches over 200 square feet we often install two fans for even airflow across the whole space.
Composite Decking That Survives Salt Air
If the porch sits on a deck surface, composite decking is the lowest-maintenance choice for our climate. Salt air does not care about composite. It does not splinter, does not need sealing, and resists the mildew that hits unsealed PT decking within a year of installation. We work with Trex, TimberTech, and Fiberon depending on the look and budget.
Water-Resistant Outdoor Furniture Pads
This is not something we sell, but it is worth a mention: even on a covered screen porch, the humidity here will mildew indoor cushions in one season. Use Sunbrella or another marine-grade outdoor fabric for cushions and pillows, and store them in a dry container during long absences. We have seen too many beautiful porches let down by furniture that lasted one summer.
Permits, Inspections, and Code in GA and SC
Most new screen porches in Chatham County, Bryan County, Beaufort County, and the cities of Savannah, Pooler, Bluffton, and Hilton Head require a building permit. The exact threshold varies but anything attached to the main house, anything with a roof, or anything over a certain square footage almost always requires one. We pull the permits, schedule the inspections, and meet the inspector on site. You do not deal with the permit office. Permitting timelines run from 2 to 6 weeks depending on the jurisdiction and the time of year, and we factor that into the schedule we give you up front.
Re-screening an existing porch or doing simple repairs to an already-permitted structure typically does not require a new permit. We will tell you which category your job falls into during the first site visit. We do not do work without the right permits and we do not let homeowners take on permit risk to save a few dollars. Zero Surprises means zero surprises from the building inspector six months after you write us the final check.
Painting and Finishing the Porch
Once the structure is framed and screened, finishing the porch the right way is the part most contractors rush. We do not. Posts, beams, ceilings, and trim all get appropriate primer and two coats of exterior-grade finish, and we coordinate stain or paint choices with whatever look you want for the space. Painting a screen porch is closely related to our exterior painting work, and we use the same humidity- and salt-air-resistant products we use on full house exteriors. If you want a stained natural-wood look on cedar beams alongside painted PT framing, we can do that combination too.
