Screen Enclosure ($8,000–$20,000)
The simplest and most affordable option. We add posts, a roof structure, and fiberglass screen panels to your existing deck. Keeps bugs out entirely while maintaining open-air airflow. Best for homeowners who mainly want mosquito protection for dining and relaxing.
Includes: Treated or aluminum posts, roof framing with shingles or metal, fiberglass screen panels, screen door, ceiling fan rough-in.
EZE-Breeze 3-Season Room ($15,000–$35,000)
Our most popular enclosure. EZE-Breeze vinyl-glazed panels replace traditional screens. They slide up like double-hung windows for full airflow in summer, then close tight for wind and rain protection in spring and fall. Extends your outdoor season from 6 months to 9–10 months.
Includes: Everything in screen enclosure + EZE-Breeze 4-track vertical sliding panels, tongue-and-groove ceiling, recessed lighting, multiple electrical outlets. Optional: ceiling heater ($500–$1,500) for chilly evenings.
Why it's the sweet spot: 70–85% ROI at resale (highest of any enclosure type), 40–60% cheaper than a full sunroom, and most Northern Virginia buyers specifically look for EZE-Breeze porches in listings.
Full Sunroom Conversion ($40,000–$80,000+)
A permanent, climate-controlled room addition. Insulated walls, real windows (double/triple-pane), HVAC connection, and finished interior. Functions as a year-round living space essentially adding a room to your home.
Includes: Insulated framing, real windows, HVAC ductwork, electrical panel connection, insulated roof, drywall or finished ceiling, flooring (tile, LVP, or hardwood).
Consideration: Full sunrooms have lower ROI (50–70%) because the cost is high relative to the appraised value increase. They make financial sense when you need the living space not as a pure investment play.
Can Your Existing Deck Handle an Enclosure?
Most decks built in the last 15 years can support a screen or EZE-Breeze enclosure if:
- Footings are adequate size (may need upsizing for roof load)
- Joists and beams are in good condition (no rot, no sag)
- Ledger board connection is solid
- Posts can accommodate roof attachment
We inspect everything before quoting. If structural upgrades are needed (joist sistering, footing enlargement), we include them in the estimate. Pro tip: If you're building a new deck and think you might want to enclose it later, tell us now we'll oversize the footings and framing at minimal extra cost.
FAQ
How much to enclose a deck?
Screen: $8k-$20k. EZE-Breeze 3-season: $15k-$35k. Full sunroom: $40k-$80k+.
Can I enclose my existing deck?
Usually yes if framing supports the weight. We inspect first. Some need footing or joist upgrades.
Screen porch vs 3-season room?
Screens keep bugs out but not wind/cold. EZE-Breeze panels close for wind/rain protection, extending use to 9-10 months. Most popular choice in NoVA.
