What drives the cost
Frame condition — redecking only works if joists and posts are sound
Board material: wood needs refinishing every 2–3 years, composite doesn't
Railings and stairs (often half the project cost)
Fastener system (hidden fasteners add cost, look better)
Repair or replace?
Replace individual rotten boards freely on a wood deck. Redeck (all boards, keep frame) when surfaces are splintering everywhere but the structure passes the screwdriver test. Full rebuild when posts or ledger show rot — that's a structural problem, not a cosmetic one.

Methodology & sources
National range is an editorial estimate from durable historical cost data; treat as a rough planning number and verify with local quotes.
State adjustment uses an editorial labor-cost index (0.85–1.35 vs national average) — a simplification of real regional variation.
Quality tiers apply published multipliers for material/type differences (Pressure-treated wood / Composite / PVC / premium composite).
Ranges exclude financing, unusual site conditions, and code-upgrade surprises.
