National 2026 data
Planning ranges based on external benchmarks published October 2026 (sources linked beside each figure), not Loudoun Decks prices or quotes. Ranges assume the area, whether the structure is new or existing, the material tier, railing, stairs, demolition, and whether permits are included or excluded, as noted in each row. Elevated, multi-level, custom railing or lighting, site access, permit and HOA conditions, and structural repairs can move a project above these ranges. Your written estimate — after a site visit and measurements — is the only project price.
National 2026 cost guides put a new screened porch at about $25–$120 per sq ft (Angi, HomeAdvisor, 2026), or roughly $7,000–$20,000 for 12x12 to 20x20 (Angi, Aug 2026). Screening an existing covered porch runs about $5–$20 per sq ft. Northern Virginia labor, permits, HOA review and roof tie-ins often push projects to the upper part of these ranges. Loudoun Decks prices each porch in a written estimate.
| Scenario | Assumptions | National 2026 data | Source and year |
|---|---|---|---|
| New screened porch | Built from scratch. Northern Virginia labor, permits, HOA review, and roof tie-ins often push a project to the upper part of the range. | About $25–$120 per sq ft. Roughly $7,000–$20,000 for 12x12 to 20x20. | Angi, updated August 3, 2026 · HomeAdvisor, Build a Porch, 2026 |
| Screen an existing covered porch | A covered porch is already in place. A new roof, new footings, and a new structure are a different scope. | About $5–$20 per sq ft. | Angi, updated August 3, 2026 · HomeAdvisor, 2026 |
Loudoun County says its Typical Deck detail cannot be used for a screened porch, which needs a full plan set, so this page does not publish a flat Loudoun screened-porch permit fee. Fairfax County requires a permit for screen porches and calculates the fee in PLUS. The published minimum base fee is $141.75 plus levy and surcharge (2026 fee schedule). That minimum is not a porch total. See Loudoun County Decks (accessed October 18, 2026) and Fairfax County permit rules.

Frequently Asked Questions
How much does a screened porch cost in Northern Virginia?
National 2026 cost guides put a new screened porch at about $25–$120 per sq ft (Angi, HomeAdvisor, 2026), or roughly $7,000–$20,000 for 12x12 to 20x20 (Angi, Aug 2026). Screening an existing covered porch runs about $5–$20 per sq ft. Northern Virginia labor, permits, HOA review and roof tie-ins often push projects to the upper part of these ranges. Loudoun Decks prices each porch in a written estimate.
Is a screened porch worth it?
Resale recovery is not a fixed percentage. The 2025 Cost vs Value report does not include a screened porch category, so this page does not publish an ROI figure. Loudoun Decks prices each porch in a written estimate.
Can you add screens to an existing deck?
Often yes, if the framing supports the added weight. National 2026 data puts screening an existing covered porch at about $5–$20 per sq ft (Angi, updated August 3, 2026; HomeAdvisor, 2026). That range assumes a covered porch already exists. We inspect before quoting. Loudoun Decks prices each porch in a written estimate.
What are EZE-Breeze windows?
Vinyl panels that convert a screened porch into a 3-season room. Slide up for airflow, close for wind and rain protection. This page does not publish an EZE-Breeze price.
