What does a screened porch cost in Hampton Roads?
Screening in an existing covered porch runs about $10 to $25 per square foot, so a 200 square foot porch is roughly $2,000 to $5,000 and a 400 square foot porch is $4,000 to $10,000. Building a new screened porch from the ground up, including foundation and roof, runs $50 to $175 per square foot. The gap between those two numbers is the single biggest cost decision in this project, and it comes down to one question: is there already a roof?
Screen material, per sq ft: fibreglass $0.20-$0.35 · aluminium and pet-resistant mesh mid-range · copper $2.00-$3.00.

Permit note: Requirements vary by locality and by whether you are screening an existing roofed porch or building a new roofed structure. Exterior Source confirms current city and HOA requirements before construction.
What makes a screened porch work in Tidewater
Three details decide whether a screened porch gets used from May to October or abandoned in July.
Airflow. The muggy season here runs roughly 21 May to 6 October, and July averages about 25 muggy days. A porch with screen on one side and solid wall on three is a hot box. Cross-ventilation, ceiling fan rough-in and screen on opposing sides are what make it comfortable.
Screen selection. Standard fibreglass is fine on an upper-level porch. At ground level, with dogs and coastal salt spray, heavier pet-grade mesh or an aluminium frame system earns its cost. Salt does reach fasteners and frames on waterfront lots.
Floor. If the porch goes over an existing deck, the decking underneath is now interior-adjacent and much harder to replace later. It is the right moment to upgrade the surface, not the moment to defer it.
- Cross-ventilation designed in, not added later.
- Ceiling fan and outlet rough-in at framing.
- Screen grade matched to ground-level, pet and salt exposure.
- Floor decided before the screen goes on, not after.
Screened porch questions
Can I screen in my existing deck?
Only if it has a roof, or you add one. Screening requires a structure to attach to. Adding a roof moves the project from the $10-$25 per square foot range into the new-build range.
Screened porch or three-season room?
A screened porch is open to outdoor air with mesh. A three-season room adds glazed panels and shoulder-season use, at meaningfully higher cost and usually a permit. In this climate the screened porch is the better value for most households; the three-season room is worth it if you want April and November.
How long does it take?
Screening an existing covered porch is typically three to five working days. A new build runs four to eight weeks including permit review.
Will it help with mosquitoes?
That is the point of it in a coastal market. Pair it with drainage that does not leave standing water, which is a reason to look at the patio grading and downspouts at the same time.
Can you add a screened porch to a new deck?
Yes, and designing both together is cheaper than doing them in sequence. The deck frame has to carry roof point loads, which means the footing plan changes.
