Deck Enclosures in Knoxville, TN
Convert your existing deck into a beautiful enclosed living space. Custom deck enclosure design and installation for Knoxville and East Tennessee homeowners.
What Is a Deck Enclosure?
A deck enclosure converts your existing outdoor deck into a fully or partially enclosed living space by adding a roof, walls, and either screens or glass panels. Instead of tearing down your deck and starting from scratch, a deck enclosure builds on the structure you already have — preserving your elevated views and outdoor connection while adding protection from insects, rain, wind, and temperature extremes.
Deck enclosures are one of the most popular projects we handle at ATC Sunrooms. Many Knoxville homeowners have a back deck they rarely use because of bugs, sun exposure, or unpredictable weather. An enclosed deck solves all of these problems while adding usable square footage to your home — often at a lower cost than building a new room from the ground up.
Whether you want a screen-enclosed deck for bug-free entertaining, a glass-enclosed deck that functions as a three-season room, or a fully insulated conversion that serves as a year-round living space, ATC Sunrooms evaluates your existing deck structure and designs an enclosure that fits your goals and your budget.
Benefits of Enclosing Your Deck
- Use your deck year-round — Stop losing your deck to bugs, heat, and rain. An enclosed deck becomes a room you’ll use every day, not just on perfect weather days
- Preserve your elevated views — Deck enclosures maintain the raised vantage point that makes decks special, now with protection from the elements
- Cost-effective conversion — Building on your existing deck framing saves thousands compared to constructing a new room addition from the foundation up
- Increased home value — An enclosed deck adds usable living space that appraisers and buyers recognize, typically returning 50-70% of the investment at resale
- Insect elimination — Screens or glass walls eliminate mosquitoes, wasps, gnats, and other pests that make Tennessee decks unusable in summer
- Flexible design — Choose screen walls for fresh-air living, glass panels for weather protection, or a combination that gives you both
Structural Considerations: Can Your Deck Support an Enclosure?
This is the most important question in any deck enclosure project, and it’s the first thing we evaluate during your free consultation. Not every deck is ready to support an enclosure without modification — but most decks can be brought up to standard with targeted reinforcement.
A deck enclosure adds significant weight to your existing structure: a roof system, wall framing, glass or screen panels, and potentially HVAC equipment. Your deck’s footings, posts, beams, and joists must be capable of handling this additional load safely and in compliance with local building codes.
What We Evaluate
- Footing depth and size — Footings must extend below the frost line and be sized to support the additional load. Shallow or undersized footings may need to be replaced or supplemented
- Post and beam condition — We inspect all support posts and beams for rot, insect damage, and structural integrity. Damaged members are replaced before enclosure work begins
- Joist size and spacing — Floor joists must be adequate for the span and load. We verify joist depth, spacing, and connection hardware
- Ledger board attachment — The connection between your deck and your house must be properly flashed and fastened to support the enclosure’s roof loads
- Decking material — Wood, composite, and PVC decking all behave differently. We assess the condition and compatibility of your existing deck surface
- Code compliance — We ensure the completed enclosure meets Knox County building codes, including load requirements, egress, and fire safety standards
If reinforcement is needed, ATC Sunrooms handles all structural work as part of your project — additional footings, post upgrades, beam reinforcement, and joist sistering. You get a single contractor, a single timeline, and a single point of accountability.
Types of Deck Enclosures
ATC Sunrooms offers three primary deck enclosure configurations. The right choice depends on how you want to use the space, your budget, and your comfort expectations.
Screen Deck Enclosure
The most affordable deck enclosure option. Mesh screen walls are installed around your deck with a new or existing roof overhead. Screen enclosures eliminate insects and debris while allowing fresh air to flow freely. They’re ideal for homeowners who primarily want bug-free outdoor living and entertaining. Screen-enclosed decks provide comfortable use from spring through fall in East Tennessee.
Glass Deck Enclosure
Glass panels replace screens, creating a weathertight room with panoramic views. Glass enclosures block wind, rain, and cold while flooding the space with natural light. Available in single-pane (three-season use) or insulated dual-pane (approaching all-season performance). Glass deck enclosures are the upgrade path for homeowners who want extended seasonal use and weather protection.
Combination Enclosure
The best of both worlds: glass panels on the weather-exposed sides of your deck and screen panels on the sheltered sides. Combination enclosures give you weather protection where you need it and fresh air where you want it. Many include operable windows in the glass sections so you can open up the room on perfect-weather days. This is our most popular deck enclosure configuration.
The Deck Enclosure Process
1. Free Structural Assessment
We visit your home, inspect your deck’s structural condition (footings, posts, beams, joists, ledger board), take measurements, and discuss your goals. You’ll receive a detailed evaluation and written estimate with no obligation.
2. Design & Engineering
Our team designs the enclosure around your existing deck dimensions. We select wall types (screen, glass, or combination), roof style, electrical layout, and finishing details. If structural reinforcement is needed, it’s included in the design.
3. Permitting & Structural Prep
We handle all building permits and HOA approvals. Before walls and roof go up, our team completes any required structural reinforcement — upgraded footings, new posts, beam reinforcement, or joist sistering.
4. Professional Installation
Our local crews build the roof system, install wall frames, mount screen or glass panels, and complete electrical and finishing work. Most deck enclosure installations are completed in 2 to 5 weeks depending on scope.
5. Final Walkthrough & Warranty
We walk through the completed enclosure with you, ensure everything meets your expectations, and provide warranty documentation. Every ATC Sunrooms project is backed by our workmanship and materials warranty.

| Enclosure Type | Typical Price Range | Best For |
|---|---|---|
| Screen enclosure (basic) | $8,000 – $15,000 | Bug-free outdoor living, lowest cost |
| Screen enclosure (premium) | $12,000 – $20,000 | Upgraded screens, ceiling fan, lighting |
| Glass enclosure (3-season) | $15,000 – $25,000 | Weather protection, extended seasonal use |
| Glass enclosure (insulated / all-season) | $20,000 – $30,000+ | Year-round comfort with HVAC |
| Combination (glass + screen) | $14,000 – $25,000 | Weather protection + fresh air flexibility |
The biggest cost variables are the type of wall system (screen vs. glass), your deck’s current structural condition (reinforcement adds cost), and whether you want climate control. Decks that are already structurally sound and have an existing roof come in at the lower end of the range.
Every deck is different. The best way to get an accurate price is to schedule a free in-home consultation. We’ll inspect your deck, discuss your options, and provide a detailed written estimate — no obligation, no pressure.

Frequently Asked Questions About Deck Enclosures
Can any deck be enclosed?
Most decks can be enclosed, but not all decks are ready for an enclosure without some structural work. The key factors are footing depth, post and beam condition, joist capacity, and ledger board attachment. During your free consultation, our team conducts a thorough structural assessment. If your deck needs reinforcement — additional footings, upgraded posts, or joist sistering — we handle that as part of the project. In rare cases where a deck is too deteriorated, we may recommend rebuilding the deck portion before enclosing.
Do I need a building permit to enclose my deck?
Yes. Knox County and most surrounding municipalities require building permits for deck enclosures because you’re adding a roof structure and modifying the building footprint. ATC Sunrooms handles all permitting, inspections, and code compliance as part of our standard process. You don’t have to deal with any of the paperwork.
How long does it take to enclose a deck?
Most deck enclosure projects take 2 to 5 weeks from the start of construction, depending on the type of enclosure and whether structural reinforcement is needed. A screen enclosure on a structurally sound deck with an existing roof might take two weeks, while a full glass enclosure requiring structural upgrades could take four to five weeks. The total timeline from consultation to completion is typically 6 to 12 weeks, including design, permitting, and material ordering.
Can I add heating and cooling to my enclosed deck?
Yes, if you choose an insulated glass enclosure. The most common approach is installing a ductless mini-split system, which provides both heating and cooling without requiring ductwork from your home’s central system. This effectively turns your deck enclosure into an all-season sunroom. Screen-only enclosures cannot be climate-controlled but can be upgraded to glass later.
Will my existing deck boards need to be replaced?
Not necessarily. If your deck boards are in good condition — no rot, warping, or structural weakness — they can remain as the floor of your enclosure. For glass enclosures intended for year-round use, some homeowners choose to upgrade to composite decking, tile, or another finished flooring material. We’ll evaluate your deck surface condition during the consultation and discuss your options.
What’s the difference between a deck enclosure and a sunroom?
A deck enclosure builds on your existing deck structure — its footings, framing, and often its floor. A sunroom is typically built on a new foundation (concrete slab) with new framing from the ground up. Deck enclosures are often more cost-effective because they leverage existing structure, but they’re limited by the deck’s dimensions and load capacity. If you need a larger room or complete design flexibility, a new sunroom addition may be the better path. Our team can help you evaluate both options during your free consultation.
