Deck replacement (custom deck building)
A deck replacement is priced like a new custom deck, because most of the work is the same: footings, framing, ledger, decking, railings and stairs.
| Tier | Typical Scope | Range |
|---|---|---|
| Custom Deck Building: Basic | Small or simple footprint, pressure-treated wood. | $8,000–$18,000 |
| Custom Deck Building: Mid-Range | Mid-size deck, composite decking, standard railings. | $18,000–$35,000 |
| Custom Deck Building: High-End | Large or multi-level deck, premium composite, custom railings and stairs. | $35,000–$70,000+ |

What moves the number
- Square footage: the size of the deck being repaired or replaced.
- Material: wood costs less upfront but needs regular maintenance; composite costs more upfront but needs little upkeep.
- Railings and stairs: material and code-required baluster spacing affect both cost and complexity.
- Levels and layout: multi-level decks and complex shapes take more time to frame than a simple rectangle.
- New build vs. replacement: replacing an existing structure may allow reusing sound framing; a new build starts from the ground up.
Why repair and replacement ranges overlap
A large repair can cost as much as a small new deck. The repair range tops out at $10,000, and a basic pressure-treated deck starts at $8,000. When a repair scope grows to include new joists, new posts, ledger work and new railings, it's worth pricing a replacement side by side. The replacement gets you current county details, new footings and a full new surface; the repair keeps what's still good. We'll show both when the call is close.
Local factors that affect scope
- Ledger condition. Fairfax and Loudoun both prohibit attaching a ledger to brick veneer, chimneys or bay windows. If yours is, the fix may be a free-standing deck design rather than a repair.
- Footings. Both counties' typical details require footings at least 24 inches below grade on solid ground. Older shallow footings can turn a repair into a replacement.
- Permits and plats. Loudoun requires a building permit and a zoning permit with a plat for all decks; Vienna adds Town zoning review to the County permit.
- Electrical. Fairfax's typical details call for at least one electrical receptacle along the deck perimeter on a new deck, which may add electrical work.
What a written deck scope should include
- Exactly which parts are repaired, replaced or reused: boards, joists, beams, posts, footings, ledger, stairs, railings.
- Decking and railing material, manufacturer and color.
- How hidden rot found after boards come up will be handled and priced.
- Ledger flashing and fastening details.
- Who applies for permits, and which office: Fairfax County, Loudoun County, the Town of Herndon or the Town of Vienna.
- Demolition, debris removal and cleanup.
