Patio Enclosures in Knoxville & East Tennessee
Transform your existing patio, porch, or deck into a beautiful enclosed living space. Custom patio enclosure design and installation by ATC Sunrooms — serving Knoxville and East Tennessee for over 25 years.
Transform Your Patio Into Livable Space
A patio enclosure converts your existing outdoor area into a protected, usable living space. ATC builds custom enclosures that integrate seamlessly with your home — from simple screen-ins to fully enclosed rooms with glass and climate control.
What Is a Patio Enclosure?
A patio enclosure converts your existing outdoor patio, porch, deck, or covered area into a fully enclosed or partially enclosed living space. Instead of building a brand-new room from the ground up, a patio enclosure leverages the structure you already have — your concrete slab, existing roof, or deck framing — and adds walls, windows, screens, or glass panels to create a protected space you can use more of the year.
Patio enclosures are one of the most cost-effective ways to add usable square footage to your home. Because much of the structural foundation already exists, an enclosed patio typically costs significantly less than a full sunroom addition while delivering many of the same benefits: protection from insects, rain, wind, and temperature extremes.
At ATC Sunrooms, we’ve been designing and installing custom patio enclosures for Knoxville-area homeowners for more than 25 years. Whether you want to screen in a back porch, enclose a concrete patio with glass, or convert a wooden deck into a year-round living space, our team evaluates your existing structure and builds a solution that fits your home, your lifestyle, and your budget.
Benefits of Enclosing Your Patio
- Maximize existing space — Stop losing your patio to rain, bugs, and heat. An enclosure turns underused outdoor square footage into a room you’ll actually use every day
- Lower cost than new construction — By building on your existing slab, roof, or deck, you save thousands compared to a ground-up addition
- Increased home value — Enclosed patios add usable living space that appraisers and buyers recognize, typically returning 50-70% of the investment at resale
- Year-round enjoyment — Depending on the enclosure type, enjoy your space from early spring through late fall — or all year with insulated glass and HVAC
- Insect and weather protection — Screens or glass eliminate mosquitoes, wasps, pollen, and debris while preserving your outdoor views
- Versatile living — Use your enclosed patio as a dining area, entertaining space, home office, playroom, or morning coffee spot
Types of Patio Enclosures We Build
Every patio is different, and so is every enclosure. ATC Sunrooms offers multiple patio enclosure styles to match your existing structure, your goals, and your budget. Explore each type to find the right fit for your home.
Patio Covers
A patio cover adds a solid, lattice, or retractable roof structure over your existing patio, providing shade and rain protection without fully enclosing the space. Patio covers are the most affordable entry point and can be upgraded to a full enclosure later. Available in aluminum, vinyl, or wood to match your home’s exterior.
Deck Enclosures
Convert your existing wooden or composite deck into a fully enclosed room with screens, glass panels, or a combination of both. Deck enclosures add usable living space while preserving your elevated views. Our team evaluates your deck’s structural capacity and reinforces as needed to safely support the enclosure.
Screen Enclosures
The simplest form of patio enclosure: mesh screen walls installed around your existing covered patio or porch. Screen enclosures keep out insects and debris while allowing fresh air to flow freely. They’re ideal for homeowners who want bug-free outdoor living at the lowest cost. Can be upgraded to glass later.
Glass Enclosures (Sunroom Conversion)
The ultimate patio enclosure: full glass walls that transform your patio into a three-season or all-season sunroom. Glass enclosures offer maximum weather protection, energy efficiency, and year-round usability. When you’re ready to upgrade from a patio to a true living space, this is the path.
The ATC Sunrooms Difference
25+ Years of Patio Enclosure Experience
ATC Sunrooms has enclosed hundreds of patios, porches, and decks across Knoxville and East Tennessee since 1999. We’ve seen every type of existing structure — concrete slabs, wooden decks, covered porches, carports — and we know how to work with what you have to create something exceptional.
Structural Assessment Included
Not every patio or deck can support an enclosure without modification. During your free consultation, we evaluate your existing structure’s load-bearing capacity, foundation condition, and connection points. If reinforcement is needed, we handle it as part of the project — no surprises.
Local, Licensed & Insured
We’re a locally owned Tennessee company with local crews — not a national franchise. Our contractors are licensed, insured, and experienced in residential patio enclosure construction. We handle permitting, inspections, and code compliance for every project.
Warranty & Financing
Every ATC patio enclosure is backed by our workmanship and materials warranty. We also offer flexible financing options to make your project affordable. Ask about our current financing programs during your free consultation.

Patio Enclosure vs. Sunroom: What’s the Difference?
Homeowners often wonder whether they should enclose their existing patio or build a new sunroom from scratch. The answer depends on your existing structure, your budget, and how you plan to use the space. Here’s how they compare:
| Feature | Patio Enclosure | New Sunroom Addition |
|---|---|---|
| Uses existing structure | Yes — builds on existing slab, deck, or roof | No — new foundation, framing, and roof |
| Typical cost | $10,000 – $50,000 | $15,000 – $70,000+ |
| Construction timeline | 1–4 weeks | 2–6 weeks |
| Climate control options | Screen only, glass 3-season, or full HVAC | 3-season or full HVAC (all-season) |
| Design flexibility | Limited by existing structure dimensions | Fully custom size and layout |
| Permitting | Usually required (we handle it) | Always required (we handle it) |
| Home value impact | Moderate — 50-70% ROI | High — 50-80% ROI |
In many cases, a patio enclosure is the smarter financial move — especially if you already have a solid patio slab or covered porch. If you want maximum design flexibility or a larger room than your existing patio allows, a dedicated sunroom addition may be the better choice. Our team can help you weigh the options during your free consultation. For a broader comparison of enclosed vs. open-air spaces, read our sunroom vs. screen room guide.
Frequently Asked Questions About Patio Enclosures
Can any patio be enclosed?
Most patios can be enclosed, but the approach depends on what you’re working with. A concrete slab patio in good condition is the easiest starting point. Wooden decks can also be enclosed but may need structural reinforcement to support the additional weight of walls and a roof. During your free consultation, our team inspects your existing structure and recommends the best approach — including any reinforcement or foundation work that might be needed.
Do I need a building permit to enclose my patio in Knoxville?
In most cases, yes. Knox County and surrounding municipalities require building permits for patio enclosures, especially when you’re adding walls, a roof, or modifying an existing structure. ATC Sunrooms handles all permitting as part of our standard process, so you don’t have to deal with paperwork or inspections.
How long does it take to enclose a patio?
Most patio enclosure projects take 1 to 4 weeks from the start of construction, depending on the type of enclosure and whether structural work is needed. A simple screen enclosure on an existing covered patio might take a week, while a full glass enclosure with HVAC could take three to four weeks. The total timeline from consultation to completion is typically 4 to 10 weeks, including design and permitting.
Can I add heating and cooling to my enclosed patio?
Yes. If you choose a glass enclosure with insulated frames and panels, the space can be connected to your home’s existing HVAC system or fitted with a dedicated ductless mini-split unit. This turns your patio enclosure into a true all-season sunroom — comfortable in every season. Screen-only enclosures cannot be climate-controlled, but they can be upgraded to glass later.
Will enclosing my patio increase my home’s value?
Enclosed patios add usable living space that buyers value. Depending on the type of enclosure and quality of construction, you can expect to recoup 50-70% of the investment at resale. Glass enclosures with climate control return more than basic screen enclosures. Beyond dollar figures, an enclosed patio makes your home more attractive to buyers and can reduce time on the market.
