About ATC Sunrooms — Knoxville’s Sunroom Experts Since 1999
Locally owned and operated for over 25 years, ATC Sunrooms has helped hundreds of East Tennessee homeowners transform their outdoor living spaces with custom-built sunrooms, screen rooms, and patio enclosures.
Over 25 Years of Building Dream Outdoor Spaces
ATC Sunrooms was founded in 1999 with a straightforward idea: East Tennessee homeowners deserve a sunroom contractor who actually lives and works in this community, knows the local building codes, and stands behind every project personally. That idea has guided our business for more than a quarter century. What began as a small, hands-on operation has grown into one of the most experienced sunroom companies in the Knoxville market — but we’ve never lost the personal approach that built our reputation.
We are a locally owned and operated company, not a national franchise or a corporate outfit that subcontracts to whoever is available. Our owner, Ray, has been in the sunroom and home improvement industry for decades and oversees every project personally — from the initial design consultation to the final walkthrough. When you work with ATC Sunrooms, you’re working directly with the people who build your sunroom. That means faster communication, better accountability, and a finished product that meets the high standard we’ve set for ourselves since day one.
Over the years, we’ve completed hundreds of sunroom installations across Knox, Anderson, Blount, and Sevier counties. We’ve built sunrooms on 1950s ranch homes in Fountain City, custom solariums in Farragut, screened porches overlooking the Smoky Mountains in Sevierville, and patio enclosures on newer construction in Hardin Valley. Every project is different, and that’s what keeps this work rewarding. Our team — including Jim, our experienced estimator, and Kelsey in the office — treats every homeowner like a neighbor, because in most cases, that’s exactly what you are.
What Makes ATC Sunrooms Different
There are plenty of contractors who will sell you a sunroom. Here’s why Knoxville homeowners keep choosing ATC Sunrooms — and referring us to their friends and family.
Custom Design
We don’t do cookie-cutter sunrooms. Every project is designed from scratch to fit your home’s architecture, your lot’s orientation, and the way your family actually lives. Whether you have a mid-century ranch, a craftsman bungalow, or a modern build, we engineer a sunroom that looks like it was always part of the house. Our design process accounts for roof pitch, foundation conditions, existing structures, and your aesthetic preferences — so the end result is seamless.
Quality Materials
A sunroom is only as good as what it’s built with. We use top-tier materials selected for durability and energy efficiency in East Tennessee’s climate: thermally broken aluminum frames, Low-E insulated glass, weathertight roofing systems, and corrosion-resistant hardware. Our sunrooms are engineered to handle Knoxville’s hot, humid summers and occasional winter ice storms without warping, leaking, or losing efficiency year after year.
Personal Service
When you call ATC Sunrooms, you talk to real people — not a call center in another state. Ray and the team are hands-on from the first consultation to the final walkthrough. Jim will visit your home, take measurements, and walk you through every option. Kelsey keeps everything organized and on schedule. You’ll always know who is working on your project and how to reach them. That kind of accountability is something the national franchises simply can’t match.
Comprehensive Outdoor Living Solutions
ATC Sunrooms is more than a sunroom contractor. We offer a full range of outdoor living and exterior home improvement services for homeowners across Knoxville and East Tennessee. Whatever your project, we bring the same attention to detail and quality craftsmanship that has defined our work for over 25 years.
Sunrooms
From all-season and three-season sunrooms to Florida rooms and glass solariums, we design and build every type of sunroom to fit your home and your budget. Each project is custom-engineered for Tennessee’s climate.
Screen Rooms
Enjoy the fresh air and backyard views without the bugs. Our screened porches and screen rooms provide full insect protection while keeping you connected to the outdoors — perfect for Knoxville’s long, warm evenings.
Patio Enclosures
Already have a patio, deck, or covered porch? We can convert it into a fully enclosed living space. Patio enclosures and deck enclosures are a cost-effective way to gain square footage by building on what you already have.
Exterior Services
Through our sister company network, we also provide roofing, siding, gutters, windows, and skylights. Whether you need a new roof to complement your sunroom or a full exterior upgrade, we have you covered.
