Enjoy the beauty of every season from the comfort of a custom year-round sunroom built for your home in Johnson City, Kingsport, Bristol TN, or Bristol VA. We install the Seaway GrandView system, a fully insulated glass room engineered for true four-season use, backed by a transferable lifetime warranty.
The Tri-Cities region of northeast Tennessee and southwest Virginia gives us four real seasons, mountain views, and weather that ranges from humid summer afternoons to snowy January mornings. A year-round sunroom lets you enjoy all of it from inside. You get the natural light, the view of Bays Mountain or your own backyard, and the connection to the outdoors, without the bugs, the wind, or the thermostat swings.
Unlike a three-season room or a screened porch, our Seaway GrandView sunrooms are fully insulated and built to hold conditioned air. That means you can run heat in February and air conditioning in July, and the room stays as comfortable as the rest of your house. For most of our Tri-Cities customers, it quickly becomes the room they use the most.
A year-round sunroom, also called a four-season sunroom, is a fully enclosed glass addition to your home designed for use in every season. It features insulated glass walls, an insulated roof, a weather-tight seal, and connections that allow it to be heated and cooled like any other room in your house.
Our sunrooms use the Seaway GrandView system, which includes thermally improved aluminum extrusions with an external element barrier, foam-filled insulation, an insulated composite roof, and the InsulGlaze 440 high-performance glass package. Every component works together as an engineered system, not a patched-together kit.
Every GrandView sunroom we install includes these premium features as standard, not upgrades:

We install year-round sunrooms throughout the Tri-Cities region, covering both northeast Tennessee and southwest Virginia. Our sunroom service area includes Johnson City, Kingsport, Bristol TN, Bristol VA, Abingdon VA, plus Greeneville, Elizabethton, Jonesborough, Blountville, and surrounding communities in Washington, Sullivan, Carter, and Greene counties in Tennessee, along with Washington County in Virginia. Homes in our region see real winters and real summers, which is exactly why a four-season room, not a three-season one, is the right investment for this climate. See our full service area.
A three-season room is lightly insulated and used from spring through fall. A four-season, or year-round, sunroom is fully insulated, weather-sealed, and connected to heating and cooling so you can use it comfortably in every month of the year. We specialize in year-round sunrooms because our Tri-Cities winters are cold enough that a three-season room sits empty for months.
Yes. A professionally built sunroom adds finished square footage, natural light, and buyer appeal, all of which typically translate to a strong return at resale. The Seaway warranty also transfers one time to the new owner, which is an added selling point.
Yes. Because the GrandView system is fully insulated, you can tie the sunroom into your existing HVAC system or use a mini-split for zoned climate control. We walk you through the best option for your home during the consultation.
Yes, and we handle it. A sunroom is a structural addition to your home, so it requires a building permit in every Tri-Cities jurisdiction we serve in both Tennessee and Virginia. We pull the permits, coordinate inspections, and make sure the installation meets all local codes.
In many cases, yes. During the free consultation, we evaluate your existing deck or concrete slab to confirm it can support the new structure. If modifications or a new foundation are needed, we walk you through the options before work begins.
Yes. The Seaway GrandView limited lifetime warranty covers the aluminum extrusions, vinyl frames, insulated panels, and hardware for as long as you own your home.
