Sunroom Installation Across East Tennessee
ATC Sunrooms designs and builds custom sunrooms, screen rooms, and patio enclosures for homeowners throughout the greater Knoxville area and beyond — from the Tennessee Valley to the Cumberland Plateau.
Serving East Tennessee Homeowners for Over 25 Years
ATC Sunrooms is a locally owned and operated sunroom contractor based in Knoxville, Tennessee. Since 1999, we’ve helped hundreds of homeowners across East Tennessee add beautiful, functional living space to their homes through custom sunroom additions, screen rooms, and patio enclosures.
Our service area spans from the heart of Knoxville outward through Knox, Blount, Anderson, Loudon, Roane, Sevier, Cumberland, and Putnam counties. Whether you live in a lakefront property on Fort Loudoun Lake, a mountain-view home near the Smokies, or a suburban neighborhood in West Knoxville, we bring the same level of craftsmanship, professionalism, and attention to detail to every project.
Every project begins with a free, no-obligation in-home consultation. We evaluate your property, discuss your vision, and provide a detailed written estimate — no pressure, no surprises. Our local crews handle everything from permitting and foundation work to final trim and cleanup.

Knoxville
Our home base and primary market. We serve neighborhoods across Knoxville including West Knoxville, Bearden, Sequoyah Hills, Fountain City, and Cedar Bluff with custom sunrooms built for the city’s mix of ranch homes, craftsman bungalows, and newer subdivisions.
Farragut
One of Knoxville’s most affluent suburbs with well-maintained homes and larger lots. Farragut homeowners frequently invest in sunroom additions to complement their properties and take advantage of the area’s beautiful, tree-lined neighborhoods.
Maryville
The county seat of Blount County and gateway to the Great Smoky Mountains. Maryville’s mix of historic homes and newer developments — many with mountain views — makes it an ideal market for sunroom additions that frame the surrounding landscape.
Oak Ridge
The historic “Secret City” is home to well-established neighborhoods with many mid-century homes that are prime candidates for sunroom additions. Oak Ridge’s DOE and ORNL employment base means homeowners with the means to invest in quality home improvements.
Sevierville
The gateway to Pigeon Forge and Gatlinburg in Sevier County. Sevierville’s growing residential areas feature both permanent homes and vacation properties, many with mountain views that a sunroom can showcase year-round.
Lenoir City
Located in Loudon County near Fort Loudoun Lake and Tellico Lake. Lenoir City’s lakefront and lake-view properties are perfect for sunrooms that maximize water views while protecting against insects and weather.
Clinton
The Anderson County seat offers small-town charm with easy access to both Knoxville and Oak Ridge. With Norris Lake nearby and affordable housing stock, Clinton homeowners are adding sunrooms to extend their living space and enjoy the area’s natural beauty.
Alcoa
Adjacent to Maryville and home to McGhee Tyson Airport, Alcoa has well-established neighborhoods built during the aluminum company era. These solid, mid-century homes are excellent candidates for sunroom additions that modernize the living space.
Powell
A growing community in north Knox County known for its family-oriented neighborhoods and strong community feel. Powell’s ranch homes and newer subdivisions offer great foundations for sunroom additions that expand your living space.
Loudon
A charming small town on the Tennessee River with a historic downtown and excellent lake access. Loudon’s quiet residential neighborhoods and riverfront properties are natural fits for sunrooms that bring the outdoors in.
Kingston
The Roane County seat sits near Watts Bar Lake, offering affordable housing and a growing community between Knoxville and Crossville. Kingston homeowners enjoy lake-area living and are increasingly adding sunrooms to capture those views.
Crossville
Known as the “Golf Capital of Tennessee,” Crossville sits on the Cumberland Plateau with cooler summer temperatures and a thriving retirement community. Mountain properties and golf-course homes here are ideal for sunroom additions.
Cookeville
Home to Tennessee Tech University, Cookeville is a growing city at the eastern edge of our service area. Its mix of established and newer neighborhoods, combined with the Upper Cumberland’s natural beauty, makes it an excellent market for sunroom additions.
