A screen porch cost estimator helps Montgomery County, MD and Fairfax County, VA homeowners budget accurately for their outdoor living upgrade. Our tool breaks down material, labor, and design costs so you understand pricing before construction begins. Get a personalized estimate based on your porch size, style, and local market conditions.
The thing that stops most Maryland and Virginia homeowners? They have no idea what it costs.
We built something to change that.
Design Builders has launched a first-of-its-kind free screen porch estimator Maryland Virginia homeowners can actually trust — real cost ranges before you ever pick up the phone.
No forms. No sales calls. No waiting on a contractor who never calls back.
In under five minutes, you'll know exactly where your project stands.
The tool walks you through the same questions our design team asks in a consultation:
Every selection updates your estimate in real time — based on actual Design Builders pricing, not national averages that don't apply to Montgomery County or Fairfax County.
Here's what most homeowners don't realize: the best screen porch projects get started in February and March — not June.
By the time Memorial Day rolls around, the best builders in Maryland, Northern Virginia, and Washington DC are booked solid. If you want your porch ready for July Fourth entertaining or fall football season, the planning conversation needs to happen now.
"The homeowners enjoying a new screen porch by summer are the ones who started planning in winter."
Starting with the estimator gives you a realistic budget before you sit down with a designer. That means your consultation is focused, efficient, and far more likely to result in a project that fits your vision and your budget.
Building in Maryland, Northern Virginia, and Washington DC comes with factors that national calculators simply cannot account for.
Montgomery County and Fairfax County each have their own setback rules, structural requirements, and permit timelines. Our estimator reflects local complexity — not a generic national average.
DMV summers are hot and humid. Winters bring ice and freezing temperatures. Every material we specify — from Fortress Steel framing to Sunspace WeatherMaster windows — is chosen to perform in this specific climate for decades.
Many neighborhoods across Maryland and Northern Virginia require architectural review. We've navigated hundreds of HOA approvals across the region and know exactly what gets approved — and what doesn't.
Screen porch projects in the DMV typically range from $35,000 for a straightforward structure to well over $150,000 for a fully appointed four-season room with Sunspace WeatherMaster windows, Archatrak porcelain flooring, Infratech heating, and premium structural details.
The estimator shows you where your specific vision lands — and where you can adjust scope without losing what matters most.
Once you've run your numbers, here's how the process works with Design Builders:
We've built screen porches across Montgomery County, Prince George's County, Fairfax County, Arlington, and Washington DC. We know what it takes to get a project approved and built to a standard that makes your home the one everyone admires.
Spring projects book fast. The homeowners enjoying a new screened porch addition by summer are the ones who started planning now.

Yes — completely free, no account required, no sales call triggered. We built it because homeowners deserve real information before they start a conversation with a screen porch builder in Maryland or Virginia.
A three-season porch uses standard or motorized screens and is comfortable from spring through fall. A four-season room incorporates Sunspace WeatherMaster insulated glass panels, Infratech heating, and sometimes cooling — making it comfortable year-round. The estimator lets you price both options.
For a summer project in Maryland or Virginia, start at least 3–4 months in advance to allow for design, permitting, and material procurement. Spring projects that start planning in March can realistically be complete by late July or August.
