Eicher's Pro Vinyl installs custom sunrooms in Pembroke, GA with our own trained employees, never subcontractors, backed by a 5-year workmanship warranty and a free in-home estimate. With summer high temperatures averaging 89.4 degrees and 166 mosquito days a year in Bryan County, a well-built sunroom is less of a luxury and more of a practical decision for how you actually use your home. We have been doing this work since 1998, and we know what holds up in southeast Georgia heat and humidity.

Three-Season vs. Four-Season: What Pembroke Homeowners Should Actually Compare

The most important decision you will make when planning a sunroom is whether you need a three-season room or a fully insulated four-season addition. Both have real merit, and the right choice depends on how you plan to use the space and what your home can support structurally.

A three-season screened sunroom is the more straightforward option. It keeps rain, insects, and wind out while letting in fresh air. We install these with 20/20 gnat-resistant screens, which matter here in Bryan County where sand gnats and mosquitoes are a fact of life for more than five months of the year. If your goal is an outdoor living feel without fighting bugs, this style delivers it at a lower upfront cost.

A four-season sunroom is insulated, climate-controlled, and functions as actual heated and cooled living space. Given that Pembroke’s cooling degree days reach 2,568 annually, a four-season room with proper insulation and energy-efficient glazing will stay comfortable even during July afternoons without running your utility bill through the roof. These rooms add usable square footage that shows up on an appraisal, which matters in a market where the median home value is $243,800 and homeownership sits at 72.8 percent.

• Three-season rooms: Lower cost, great ventilation, screened against insects, ideal for spring and fall use
• Four-season rooms: Fully insulated, year-round use, adds appraised living area, higher investment
• Both options: installed by Eicher’s employees, 5-year workmanship warranty, free in-home estimate

We will walk you through both options at your home so you can make the comparison based on your actual layout and goals, not a sales pitch.

Why Vinyl Framing Outperforms Wood in Bryan County's Climate

Pembroke sits in hardiness zone 9a, which means mild winters but aggressive heat, humidity, and a very heavy termite risk classification. Those conditions make wood-framed sunrooms a gamble. Wood frames can warp, rot, and become termite food over time, especially in a structure that sees direct sun, rain, and damp Georgia air year-round.

Vinyl framing does not rot, does not provide a food source for termites, and does not need painting or staining to stay protected. Our vinyl-framed sunroom systems hold their shape and color without the seasonal maintenance that wood demands. For homeowners whose houses were built around the year 2000, which is the median home age for this area, a well-maintained exterior addition in matching vinyl can extend the life and look of the property without constant upkeep.

Wind is also a consideration. Bryan County sees wind gusts up to 44.1 mph, and Pembroke carries moderate hurricane exposure at 67 miles from the coast. Our sunroom installations use frames and glazing rated to handle that kind of lateral load, and we pull the proper permits so everything is built to Georgia code from day one.

Glass Options: What the Glazing Choice Actually Changes

The glazing in your sunroom, meaning the glass or panel system in the walls and roof, has more impact on comfort and cost than almost any other single decision. Here is how the main options compare for a Pembroke home.

• Single-pane glass: Lowest upfront cost, but transfers heat quickly. In a climate averaging 89.4 degrees at the high end, a single-pane sunroom can feel like an oven from June through September.
• Insulated glass units (double-pane): Significantly better thermal performance. The air gap between panes slows heat transfer, which is important given Pembroke’s 2,568 cooling degree days per year.
• Low-E coated glass: Adds a microscopic coating that reflects infrared heat while still letting in visible light. This is the option we most often recommend for four-season rooms in southeast Georgia.
• Polycarbonate panels: Lighter than glass, good insulation value, often used in roof sections. Less clear optically, but very durable under hail and storm conditions.

We will bring samples and spec sheets to your free in-home estimate so you can see and feel the difference between options before committing to anything. There is no pressure and no time limit on that conversation.

How a Sunroom Addition Fits Into a Pembroke Home's Value

Bryan County has seen steady growth as part of the Savannah metropolitan area, and with a homeownership rate of 72.8 percent and a median home value of $243,800, most Pembroke homeowners are building equity they want to protect. A sunroom, particularly a four-season addition that adds appraised square footage, is one of the few home improvement projects that directly contributes to that number.

A three-season screened room may not add appraised square footage in the same way, but it does add usable outdoor living space that buyers in this part of Georgia actively look for, especially given how much of the year the weather is pleasant enough to enjoy a screened porch. Either way, you are adding something functional to a home that most Pembroke residents plan to stay in long-term.

We also offer 100 percent financing with no money down, on terms of 5, 7, or 10 years, plus a one-year same-as-cash option. Military families and senior citizens receive additional discounts, which matters in a county that includes Fort Stewart just 18 miles away. A sunroom does not have to be a project you wait years to afford.

Screens, Ventilation, and the 166-Mosquito-Day Reality

If you have spent a summer evening in Pembroke trying to enjoy the backyard, you already understand why screen quality is not a minor detail. Bryan County logs 166 mosquito days per year, and sand gnats can be active from early spring through late fall. A standard screen will keep out larger insects, but it will not stop gnats.

Our screened sunrooms use 20/20 gnat-resistant screen mesh, which has a tighter weave than standard screen and is specifically designed for the insect conditions common in coastal and southeast Georgia. This is not an upgrade we charge extra for because in this region, it is simply the right screen to install.

Ventilation design also matters. We work with you on the placement and size of screened openings so you get airflow on mild days without creating a wind tunnel or a security concern. A well-ventilated three-season room in Pembroke can be comfortable with the windows open from September through May, which is a significant portion of the year in zone 9a.
