See What We Can Build for You
For over 25 years, ATC Sunrooms has been designing and building custom outdoor living spaces for Knoxville homeowners. Every project is built to match your home, your budget, and your vision.
What We Build
ATC Sunrooms offers a complete range of outdoor living solutions for homeowners across Knoxville and East Tennessee. Every project is custom designed, engineered for Tennessee’s climate, and built by our local crews.
Sunrooms
All-season, three-season, Florida rooms, and solariums. Our custom sunroom additions give you year-round living space with floor-to-ceiling views, natural light, and climate control designed for East Tennessee weather.
Screen Rooms
Screened porches and screen room enclosures that let you enjoy fresh air and open views without mosquitoes, gnats, or pollen. The most popular outdoor living upgrade in the Knoxville area.
Patio Enclosures
Convert your existing patio, deck, or covered porch into an enclosed living space. Patio enclosures and deck conversions are a cost-effective way to add usable square footage to your home.
Exterior Services
Roofing, siding, gutters, windows, and skylights for Knoxville homeowners. Our exterior services team handles everything from roof replacements to energy-efficient window installations.
Why Knoxville Homeowners Choose ATC Sunrooms
When you hire ATC, you’re working with a local company that’s been building sunrooms in East Tennessee since 1999 — not a national franchise, not a fly-by-night crew. Here’s what sets us apart.
25+ Years of Local Experience
ATC Sunrooms has been designing and installing custom sunrooms for Knoxville homeowners since 1999. We’ve completed hundreds of projects across Knox, Blount, Anderson, and Sevier counties. Our experience means we know exactly what works in Tennessee’s climate — the materials that last, the designs that perform, and the building practices that pass inspection the first time.
Custom Design & Build
No cookie-cutter kits. Every sunroom, screen room, and patio enclosure we build is engineered specifically for your home’s architecture, your lot’s orientation, and your family’s lifestyle. Owner Ray works directly with each homeowner to design a space that integrates seamlessly with your existing home — from the roofline down to the trim details.
A Local Knoxville Company
We’re based right here in Knoxville. Our crews live and work in East Tennessee. When you call ATC, you talk to the people who will actually build your sunroom — not a call center in another state. We handle permitting, inspections, HOA requirements, and every detail of your project from start to finish.
From Dream to Reality — Custom Sunroom Solutions
Building a sunroom is one of the best investments you can make in your Knoxville home. It adds living space, increases your property value, and gives you a place to enjoy East Tennessee’s natural beauty without the bugs, heat, or unpredictable weather.
At ATC Sunrooms, every project starts with a free, no-pressure in-home consultation. We evaluate your space, listen to your goals, and design a sunroom that fits your home, your lifestyle, and your budget. Our process is straightforward — no high-pressure sales tactics, no bait-and-switch pricing. Just honest recommendations from a contractor who’s been doing this for over 25 years.
Whether you want a bright all-season sunroom for year-round use, a breezy screened porch for summer evenings, or a patio enclosure to make the most of your existing outdoor space, we have the experience and craftsmanship to bring your vision to life.

Don’t just take our word for it. Here’s what Knoxville homeowners have to say about working with ATC Sunrooms.
“ATC created an enclosure on our patio. Ray, the owner, gave us some upgraded options before starting the job at no additional costs. Highly professional and the work was outstanding. We would recommend ATC to anyone looking for quality workmanship at a fair price.”
— Stephanie Canterbury
“We had ATC build a screened-in porch on the back of our home and the results exceeded our expectations. The crew was professional, showed up on time every day, and the finished product is beautiful. We use it almost every evening now. Absolutely the best home improvement decision we’ve made.”
