    Deck & Patio Sub-Type Comparisons

    Concrete Patio vs Paver Patio

    Concrete patios are the cheapest hard surface at $14–$20/sq ft but crack; pavers cost $25–$45/sq ft, allow individual repair, and add resale appeal in LA.

    Composite Deck vs Wood Deck

    Composite (Trex/TimberTech) costs $40–$75/sq ft and is maintenance-free for 25+ years; pressure-treated wood is $28–$45/sq ft but needs re-staining every 2–3 years in LA sun.
