Eicher's Pro Vinyl installs custom sunrooms in St. Simons, GA with our own trained employees (never subcontractors), a 5-year workmanship warranty, and a free in-home estimate. Just a tenth of a mile from the coast, St. Simons Island homeowners know better than most that every square foot of comfortable, protected living space counts when the barrier island heat, humidity, and those notorious coastal gnats make being fully outdoors less than pleasant for much of the year.

Starting the Process: What a Sunroom Consultation Looks Like on St. Simons Island

When you call Eicher’s Pro Vinyl at (912) 588-0061, we schedule a free in-home estimate at a time that works for you. One of our experienced team members comes to your home, looks at your existing foundation and roof lines, talks through how you use your outdoor spaces, and helps you understand what a three-season or fully insulated four-season sunroom would actually cost and feel like in your specific situation.

St. Simons Island sits in zip codes 31522 and 31527, and homes throughout Glynn County in zip codes 31520 and 31525 share similar construction characteristics. With a median home build year of 1986, many island homes were designed without a dedicated sunroom, but their footprints and lot layouts often make them ideal candidates for an addition that adds real, usable square footage.

We bring samples, discuss glazing and screen options suited to coastal conditions, and walk you through financing before we leave. There is no sales pressure and no obligation. Our goal at the estimate is simply to give you enough information to make a confident decision on your own timeline.

Choosing the Right Sunroom Style for Island Living

Not every sunroom is the same, and the differences matter a great deal when you live 0.1 miles from the coast with high hurricane exposure and 179 mosquito days per year on record for this area.

• Three-season sunrooms are a popular starting point. They use screened or single-pane panels and are built for spring, fall, and mild winter use. Our 20/20 gnat-resistant screens are a standard recommendation here because St. Simons sand gnats are genuinely relentless from late spring through early fall.
• Four-season sunrooms are fully insulated, climate-controlled additions. Given the area’s 2,716 cooling degree days annually and high summer temperatures that regularly reach the upper 80s, a four-season room with proper insulated glazing lets you actually use the space from January through December without running up your energy bill.

We walk you through both options clearly, with real numbers on cost and performance, so you can weigh what makes sense for your home and your budget. Homeownership in Glynn County sits at 66.7 percent, and a well-built sunroom is one of the more straightforward ways to add functional living space to a home you plan to stay in for years.

How We Build: Materials, Crews, and Quality Control

Every sunroom Eicher’s Pro Vinyl installs is built by our own employees. We have never used subcontractors, and that policy has held since we opened in Jesup, Georgia in 1998. On an island community like St. Simons, where word travels fast among neighbors and HOA communities near Mallery Park or along the Frederica Road corridor, our reputation depends on every single job being done right.

Our vinyl framing systems are selected for durability in coastal environments. We use Color Through vinyl where applicable, meaning the color runs all the way through the material rather than sitting on the surface, so it does not chip or fade under the sun and salt air that St. Simons homeowners deal with constantly. Glazing is selected based on the room’s orientation and your insulation needs.

Termite risk in this part of Glynn County is rated Very Heavy, so we are deliberate about minimizing wood framing contact points wherever the design allows, and we discuss treatment options with every homeowner during the planning phase. When the installation is complete, your sunroom is covered by our 5-year workmanship warranty in addition to the applicable manufacturer warranties on materials.

Financing a Sunroom Addition Without Draining Your Savings

A quality sunroom is an investment, and Eicher’s Pro Vinyl offers 100 percent financing with no money down so the project does not have to wait until you have saved up the full amount. We offer 5-year, 7-year, and 10-year financing plans, along with a 1-year same-as-cash option for homeowners who plan to pay it off quickly.

Military families and senior citizens receive additional discounts, which matters on St. Simons Island where a significant portion of Glynn County’s population falls into one or both of those categories. If you are unsure what you qualify for, ask us during your free in-home estimate and we will walk through the numbers with you.

The median home value in this area is around $204,900, and a sunroom addition that is properly designed and installed tends to hold its value well, particularly in a coastal resort and residential community where usable indoor-outdoor living space is something buyers actively look for. Homeowners in nearby Brunswick (about 6 miles away) and Country Club Estates have found the same thing.

What to Expect After Installation: Warranties and Long-Term Performance

Once your sunroom is installed, Eicher’s Pro Vinyl stands behind the work with a 5-year workmanship warranty. That covers the installation itself, including framing connections, panel seating, door operation, and screen fit. Manufacturer warranties cover the materials according to their own terms, which we explain clearly before you sign anything.

Sunrooms in St. Simons, GA face real weather stress over time. The combination of high humidity, salt air, and wind gusts that have been measured up to 46.1 mph in Glynn County means your sunroom needs to be built to handle movement and moisture, not just look good on installation day. Our crews account for that from the first structural measurement to the final caulk line.

Homeowners in zip codes 31522 and 31527 have been calling us for exterior remodeling work for years, and many of them come back when they are ready for the next project. That kind of repeat business only happens when the first job holds up the way it should. We service what we sell, and our Jesup showroom at 341 Cameron Rd is always open if you have questions after your project is complete. We also have a Brunswick location closer to the island for Glynn County customers.
