How Much Does a New Deck Cost in Northern Virginia? (2026 Real Numbers)

NOVA deck pricing in 2026 is higher than it was in 2022 — materials are up, labor is up, and permit fees in Fairfax and Loudoun went up again this year. Here are the real numbers Vision Custom Build & Remodel quotes today, so you can plan a budget that actually matches what you will sign.

Quick price ranges by size (Trex composite, standard railing, attached to house)

Deck size	Price range
12' x 14' (168 sq ft)	$18,000 – $26,000
16' x 20' (320 sq ft)	$28,000 – $42,000
20' x 24' (480 sq ft)	$40,000 – $58,000
24' x 30' + stairs (720 sq ft)	$58,000 – $85,000
Multi-level / wraparound 800+ sq ft	$80,000 – $140,000+

These are turn-key numbers including permits, footings to frost depth, framing, composite boards, aluminum railing, and one set of stairs.

What drives NOVA deck cost up or down

Material (single biggest variable)

• Pressure-treated pine: subtract ~30% from the table above
• Cedar: subtract ~10%
• Trex Transcend: baseline (the table above)
• TimberTech AZEK or Deckorators: add 15–25%

Railing

• Aluminum picket (most popular in NOVA): included
• Cable rail: add $80–$120 per linear foot
• Glass panel: add $150–$220 per linear foot

Height off the ground

• Ground-level (under 30"): cheapest, no railing required by code in most cases
• Standard (3–8 ft): baseline
• Second-story / walk-out basement: add 20–35% for taller posts, beams, and longer stair runs

Features that add real money

• Built-in bench seating: +$2,000–$4,500
• Pergola or shade structure: +$4,000–$12,000
• Outdoor kitchen rough-in (gas, water, electric): +$3,000–$8,000
• Stone fireplace or fire pit: +$6,000–$25,000
• Lighting package (post caps, riser lights): +$1,500–$4,000

County-by-county permit cost in 2026

• Fairfax County: $350–$650 for a typical residential deck permit
• Arlington County: $400–$700
• Loudoun County: $300–$550
• Prince William County: $250–$450
• City of Alexandria: $500–$900 (historic district adds review fees)
• City of Falls Church: $400–$700

Vision Custom Build & Remodel includes the permit fee in every fixed-price contract. If your quote does not, ask why.

Why some quotes are 40% lower (and what they leave out)

If you get three quotes and one is dramatically cheaper, it is almost always missing one of these:

• No permit pulled (illegal, and a problem at resale)
• Footings only 12–18" deep (NOVA frost depth is 30" — these decks heave and shift in winter)
• Substandard ledger flashing (water gets behind the ledger and rots the rim joist of your house)
• 6/4 deck boards instead of 5/4 with wider joist spacing (bouncy floor, voids warranty)
• No stairs included ("stairs are extra")
• Pressure-treated railing instead of aluminum (rotted out in 5 years)

A real, code-compliant, permitted Trex deck in Northern Virginia in 2026 starts around $90–$130 per square foot all-in. Below that, somebody is cutting something they should not.

FAQs

Q: Does a new deck increase home value in NOVA? Yes — Remodeling Magazine's 2025 Cost vs Value report shows composite decks recouping 50–62% of cost at resale in the DC metro. More importantly, a clean modern deck makes the house show better and sell faster, which matters more than the dollar recoup.

Q: Can I finance a deck project? Most NOVA homeowners use a HELOC, home equity loan, or a contractor financing partner. Vision Custom Build & Remodel can connect you with financing partners that quote in 24 hours.

Q: How much for just the design and permit drawings? $1,200–$2,500 standalone. We credit this back if you build with us.

Q: Are tear-out and disposal of the old deck included? Yes — we quote teardown, dumpster, and disposal as a single line item, typically $2,000–$5,000 depending on size and access.
