Plan the scope first
Loudoun Decks does not publish a per-square-foot rate. Demolition, structure, stairs, railings, and permits are priced in a written estimate.
Don't let an aging, splintering deck hold you back. We inspect old structures, separate repair from replacement, and build low-maintenance outdoor retreats with permit and HOA planning included in the written scope.

Quick answer
A deck should usually be replaced when the ledger connection, footings, posts, joists, stairs, or railings show widespread deterioration, when the frame cannot safely accept new composite boards, or when repairs approach the cost of a rebuild. Replacement also resets structural details for current permit review, HOA documentation, modern railing systems, and low-maintenance composite or PVC decking.
External 2026 planning benchmarks, not Loudoun Decks prices: resurfacing composite decking on a structure that has been confirmed sound is about $15–$45 per square foot (LatestCost, September 25, 2026), or about $4,800–$14,400 for 320 square feet and $6,000–$18,000 for 400 square feet. Demolition of an old deck, when it applies, is a separate about $5–$15 per square foot (Angi, updated September 29, 2026), or about $1,600–$4,800 for 320 square feet and $2,000–$6,000 for 400 square feet. Angi also publishes one 360-square-foot replacement example of $7,200–$16,900, combining demolition, materials, and labor. A written estimate after a site visit and measurements is the only project price.
Old framing can sometimes be reused, but only if it is structurally sound, code-compliant, properly flashed, and compatible with the new decking system. Many replacement projects reveal ledger, joist, stair, or footing issues that should be corrected before new boards and railings are installed.
Most full replacement builds take 2–4 weeks once permits and material selections are complete. Inspections, weather, HOA review, and project complexity can extend that construction window.
Many deck replacements in Northern Virginia require permits when structural components, footings, ledgers, stairs, railings, or layout dimensions change. Permit requirements vary by county and project scope. Homeowners should confirm requirements before construction so inspections, code details, and HOA documentation are handled correctly.
Composite is often worth considering for replacement when the homeowner wants lower maintenance, better long-term appearance, and fewer staining or sealing cycles. The value depends on project budget, expected ownership period, sun exposure, design goals, and whether the existing frame needs significant structural work.
Replacement triage
Full replacement is a high-value path when it solves safety, code, layout, and long-term material goals together. It should not be the default answer for isolated repair items or a frame that still qualifies for resurfacing.
Planning ranges based on external benchmarks published October 2026 (sources linked beside each figure), not Loudoun Decks prices or quotes. Ranges assume the area, whether the structure is new or existing, the material tier, railing, stairs, demolition, and whether permits are included or excluded, as noted in each row. Elevated, multi-level, custom railing or lighting, site access, permit and HOA conditions, and structural repairs can move a project above these ranges. Your written estimate — after a site visit and measurements — is the only project price.

A new composite deck, as distinct from resurfacing, is planned on composite deck cost in Northern Virginia. Wood-to-composite conversion details are on replace a wood deck with composite. This page is the deck replacement page.
| Part | What to look at | Published guidance |
|---|---|---|
| Ledger | Flashing, the connection to the house, and rot at that joint. | Trex resurfacing guidance says to check ledger attachment, flashing, joists, and hardware before new boards go on. A failed ledger is a replacement issue. |
| Joists | Soft spots, span, and spacing for the board you want. | New boards do not correct deteriorated joists. Confirm spacing in the selected product guide. TimberTech publishes joist-spacing instructions. |
| Footings | Movement, post bases, and whether the footings will change. | Loudoun County (accessed October 18, 2026) requires a building permit and a zoning permit for every deck, with footing, framing, and final inspections. |
| Stairs and guards | Stringers, connections, and any change to stair or guard layout. | Work that changes stairs or guards is structural. Fairfax County requires a permit for decks, including alterations. |

Replacement projects often depend on county permit review, HOA rules, access, and existing framing conditions. Use the local planning page closest to the property before requesting a written replacement estimate.
Replacement usually deserves serious consideration when the ledger connection, footings, posts, joists, stairs, or railings have widespread deterioration, when the framing cannot safely support new boards, or when repair costs are approaching the cost of a rebuild. A structural evaluation should happen before that decision is made.
Sometimes. Reuse depends on framing condition, age, spans, fasteners, flashing, footing depth, permit history, and whether the frame is suitable for the new decking and railing system. If the frame is not sound, replacement is safer than covering old problems with new boards.
Most full deck replacements in Loudoun, Fairfax, and Prince William counties require permit review, especially when framing, footings, ledger attachment, stairs, or guardrails are involved. HOA approval may also apply in communities such as Ashburn, Leesburg, Brambleton, South Riding, Reston, Vienna, and Gainesville.
Composite or PVC decking often makes sense during a full replacement because the structure is already being reset. Homeowners commonly compare pressure-treated wood, Trex, TimberTech, and AZEK based on upfront cost, maintenance, heat, color, railing options, and long-term ownership goals.
