Why Porches Matter

The DMV has porch weather six months a year.

You moved here for the seasons. A real porch — not a deck, not a patio — extends every season by months. Front porches give your house presence and a place to actually sit. Back porches and screened-in rooms become the most-used space in the house from April through October.

Building one right takes more than carpentry. It takes foundation, roof structure, integration with the existing house, and a finishes-grade attention to detail that most contractors skip.

That’s where 50 years of DMV experience pays off. Our porches are built like additions, because that’s what they are.

What changes the number for your home

  • Square footage. Per-sqft cost drops slightly on larger builds but total cost scales
  • Foundation type. Concrete piers vs. helical piles vs. full slab
  • Roof structure. Integrating with existing house roof; matching pitch and shingles
  • Floor material. Pressure-treated < composite < tropical hardwood
  • Screening / glazing. Open vs. screened vs. windowed each adds materials and labor
  • Railings. Aluminum vs. composite vs. cable rail vs. custom millwork
  • Electrical / lighting. Outlets, ceiling fans, recessed lights all add separate permits
  • Permits. All porch builds require permits + structural inspection in DMV jurisdictions

Why Four Seasons

Most contractors build decks. We build porches like additions.

Foundation, structural roof tie-in, finished ceiling, electrical — porches require addition-level competence.

Integrated roof tie-in

Porch roofs tie into your existing house roof — flashing, valleys, and matching shingles. We do it right; cheap builders leak.

Frost-depth piers, helical piles where needed. Permitted and inspected.

Common Questions

Porch questions DMV homeowners ask.

How much does a porch cost in the DMV?

Covered porches: $20,000-$40,000 for a 200-300 sq ft build. Screened porches: $35,000-$75,000. Three-season rooms with glass: $75,000-$150,000+. Final cost depends on size, foundation type, and finish level.

How long does a porch build take?

Construction typically takes 4-8 weeks. Permit time adds 2-4 weeks upfront. Three-season rooms with HVAC integration can run 8-12 weeks.

Do you handle permits?

Yes, in your name. All porch builds require building permits + inspection in DMV jurisdictions. We handle the application, HOA approval, and inspections.

What's the difference between a porch and a deck?

A porch has a roof. A deck is open to the sky. A porch is an extension of the house with proper foundation and structural integration; a deck is a freestanding (or attached) outdoor platform.

Should I do composite or wood decking?

Composite (Trex, TimberTech) for 90% of our clients. 25-50 year warranties, no maintenance, holds value. Tropical hardwoods (ipe, mahogany) for premium aesthetics on premium budgets.

Can you add a porch to a house that doesn't have one?

Yes — most additions are exactly that. We design the porch to look like it was always part of the house: matching trim, roof pitch, columns, and color.

Can you do screened porches or three-season rooms?

Yes. Screened porches use Phantom retractable screens or fixed screen panels. Three-season rooms use specialized window systems (Eze-Breeze, Pella, Andersen).

Do you offer financing?

Yes. $0 down, 0% interest for 12 months on approved porch projects.
