| Bug protection | None | Full |
| Rain use | No | Yes (roof + screens) |

| Sunbathing | Yes | Filtered through screen |
| Resale ROI | 65–80% | 70–85% |
| Maintenance | Occasional wash | Occasional wash + screen repair |
| Permit complexity | Standard | Higher (roof structure + electrical) |
| Construction time | 2–4 weeks | 3–6 weeks |

When to Build a Deck
- You love grilling outdoors open-flame cooking isn't safe in an enclosed porch
- Budget under $30k more square footage for the money
- You want full sun tanning, gardening, open-air feeling
- Multi-level yard decks handle slopes better than porches
When to Build a Screened Porch
- Bugs are a dealbreaker mosquitoes, stink bugs, gnats kept out entirely
- Pollen allergy screens reduce pollen exposure significantly in spring
- You entertain often dining, games, TV watching without weather interruption
- 3-season or 4-season use EZE-Breeze windows extend into Nov/Mar
- Higher ROI priority porches return 70–85% vs 65–80% for decks
The Best of Both: Deck + Porch Combo
Our most popular configuration: an open composite deck (250–350 sqft) with a connected screened porch (150–250 sqft). The deck serves as the grill and sun zone; the porch is the dining and relaxation zone.
Combo cost: $45,000–$75,000 (30–40% less than building separately).
Example project: 300 sqft Trex Transcend deck + 200 sqft screened porch with EZE-Breeze windows, beadboard ceiling, and ceiling fan in Centreville = $52,000.
Can You Convert a Deck into a Porch Later?
Yes if the existing deck framing can support the added roof weight. We inspect the structure before quoting. Converting typically costs $20,000–$40,000 depending on size and features. If you think you might want a porch later, tell us during deck design we can oversize the footings and framing now (minimal added cost) to make future conversion easy.
