About 66.7 percent of Glynn County residents own their homes, and a growing number of Jekyll Island homeowners are adding sunrooms to make the most of the island's natural light without fighting the heat and insects that come with it. Sunrooms in Jekyll Island, GA require materials and framing details that hold up to salt air, heavy termite pressure, and the kind of humidity that settles in by mid-morning. Eicher's Pro Vinyl has been doing this work since 1998, and our crews are employees, not subcontractors.

Three-Season vs. Four-Season: What Jekyll Island Homeowners Actually Need to Compare

The first decision most homeowners face is whether to build a three-season sunroom or a fully insulated four-season sunroom addition. On Jekyll Island, that choice matters more than it does inland, and here is why.

A three-season room uses screened or single-pane glazed panels and is not conditioned with heating or cooling. From October through April on the island, that works well. But Jekyll Island averages 2,724 cooling degree days per year, and average summer highs reach 87.3 degrees Fahrenheit. A three-season room in July becomes uncomfortable without climate control, and you will not use it during the months you want it most.

A four-season room is framed with insulated vinyl, uses thermally broken window systems, and can be tied into your home’s HVAC or fitted with a mini-split. You get the view and the light year-round without the heat penalty. For most Jekyll Island homeowners, the four-season build is the better long-term value.

• Three-season pros: lower upfront cost, good for mild-weather use, lighter structural load
• Three-season cons: unusable in summer heat, limited insulation value, less energy efficiency
• Four-season pros: year-round comfort, adds conditioned square footage, higher resale value
• Four-season cons: higher initial investment, requires HVAC planning

We walk through both options during every free in-home estimate so you can make the call with real numbers in front of you, not guesswork.

Why Vinyl Framing Wins Against Wood and Aluminum on a Barrier Island

Jekyll Island sits roughly one mile from the coast, and the termite risk rating for this area is classified as Very Heavy. That rating is not a formality. Subterranean termites along Georgia’s barrier islands are aggressive, and any wood framing in a sunroom addition is a long-term liability without ongoing chemical treatment.

Aluminum framing is a step up from wood in terms of pest resistance, but aluminum conducts heat and cold efficiently, which means it works against you in both summer and winter. Condensation on aluminum frames in humid coastal air is a recurring maintenance issue as well.

Vinyl framing does not absorb moisture, will not rot, and gives termites nothing to eat. It also insulates better than aluminum, which matters when you are trying to keep a sunroom comfortable through a Georgia coastal summer. Our vinyl framing is color-stable and does not require painting or staining, which reduces the long-term maintenance load significantly.

Jekyll Island’s high tree canopy also means a lot of organic debris, including Spanish moss, pine needles, and leaf litter, collects on and around structures. Vinyl surfaces shed that material more easily than wood and do not stain the way painted surfaces do when wet debris sits against them for days after a heavy rain. With 41.6 inches of annual precipitation and up to seven heavy rain events per year, that is a practical consideration worth thinking through before you choose a framing material.

Screens That Actually Keep Sand Gnats Out: What to Ask For

Anyone who has spent a late afternoon near Jekyll Island State Park or along the marsh edge knows that standard window screen mesh is not fine enough to stop sand gnats. Standard mesh runs 18 by 16 strands per inch. Sand gnats are smaller than that.

We install 20/20 gnat-resistant screens as a standard option on our three-season rooms and screened sunroom enclosures. The tighter weave keeps out the no-see-ums that make coastal Georgia evenings miserable from late spring through early fall. With an estimated 186 mosquito-activity days per year in this region, a well-screened sunroom is not a luxury, it is a practical upgrade that changes how you use your outdoor-adjacent spaces.

If you are comparing proposals from different contractors, ask specifically what screen mesh they use. A screen that looks identical to the eye can perform very differently when the gnats come out at dusk near the island’s maritime forest edge. It is a small spec detail that makes a large difference in how often you actually use the room.

Hurricane Exposure and How We Build for High-Wind Coastal Conditions

Jekyll Island carries a high hurricane exposure rating, and it is in a wind zone that demands more from a sunroom structure than you would need 50 miles inland. The island recorded a maximum wind gust of 49 mph in available weather data, but tropical systems that move through the Georgia coast routinely exceed that during a named storm.

Our sunroom installations use anchoring and framing details suited to coastal Georgia building codes. We are licensed and insured in Georgia, and every job is permitted and inspected through the appropriate Glynn County channels. This is not something to leave to a crew that is not familiar with coastal construction requirements.

The homes on Jekyll Island average a construction year of around 1986, which means many of the existing structures were built before modern coastal wind codes were tightened. If you are adding a sunroom to an older home, the connection between the new addition and the existing structure needs careful attention. Our team has been doing these assessments since 1998 and will tell you honestly during the estimate if any reinforcement is needed before work begins.

Financing a Sunroom Addition Without Draining Your Savings

A quality four-season sunroom is a meaningful investment, and we understand that not every homeowner wants to write a single large check to make it happen. We offer 100 percent financing with no money down, including five-year, seven-year, and ten-year term options. There is also a one-year same-as-cash plan for homeowners who want to spread payments over the short term without carrying interest.

Military families and senior citizens receive discounts on their projects. Jekyll Island and the surrounding Golden Isles area include a significant number of retired residents and active-duty personnel stationed near Kings Bay Base, about 20 miles south, and we have been working with those communities for decades.

Every project starts with a free in-home estimate. We come to you, look at the space, talk through the options, and give you a clear written number. There is no sales pressure and no obligation. If you want time to think it over or compare it to another proposal, that is completely fine with us. We have been around since 1998 and are not going anywhere.
