Deck costs vary significantly by size, decking material, structural complexity, and regional labor rates. Here’s a practical overview of what to expect in many regions in 2026, along with what questions confirm the quotes you’re getting are comparable.
“The most common budget mistake on decks is comparing quotes that aren’t specifying the same footing depth, the same structural member sizes, or the same decking product. A quote that’s $8,000 cheaper might be using 18-inch footings and builder-grade composite while the other uses 48-inch footings and a premium product. Those aren’t the same deck.”

Deck Cost by Decking Material (your region, 2026)
Pressure-Treated Lumber Deck
| Size | Typical installed range |
|---|---|
| Small deck (10′ x 12′, 120 sq ft) | $6,000 – $10,000 |
| Medium deck (14′ x 16′, 224 sq ft) | $10,000 – $18,000 |
| Large deck (20′ x 20′, 400 sq ft) | $18,000 – $30,000 |
Composite Decking (mid-range product)
| Size | Typical installed range |
|---|---|
| Small deck (10′ x 12′, 120 sq ft) | $10,000 – $16,000 |
| Medium deck (14′ x 16′, 224 sq ft) | $18,000 – $28,000 |
| Large deck (20′ x 20′, 400 sq ft) | $30,000 – $50,000 |
Premium Composite or PVC Decking
Add 20–40% over mid-range composite for premium brands (Azek, TimberTech Landmark, Trex Transcend).
What Drives Deck Costs Up
Decking material. Composite costs 2–3× more than pressure-treated lumber for the surface; PVC costs more still. However, composite’s lower maintenance costs narrow the lifecycle cost gap.
Structural complexity. Elevated decks, multiple levels, curved shapes, and complex stair configurations all add labor and materials cost.
Railing system. A basic wood post-and-baluster railing adds $30–$60 per linear foot. Cable railing runs $100–$200/lf. Glass panel railing runs $200–$400/lf.
Hot tub platform. A deck designed to support a hot tub requires additional structural engineering — posts, beams, and footings must handle a significantly increased point load. Budget an additional $3,000–$8,000 for hot tub-specific structural requirements.
Permits and inspections. Permit fees in many regions typically range from $300–$1,500 depending on municipality and project value. These should be included in the contractor’s quote.
Site conditions. Difficult access, sloped sites requiring retaining walls, or rock encountered during footing excavation all add cost.
Fence Costs (your region, 2026)
| Material | Typical installed cost (per linear foot) |
|---|---|
| Pressure-treated pine (basic privacy fence) | $35 – $55 |
| Cedar privacy fence | $45 – $75 |
| Vinyl fence (6′ privacy) | $50 – $90 |
| Aluminum ornamental fence (4′) | $40 – $80 |
| Chain link (4′, residential) | $20 – $40 |
Gates add $400–$1,500 each depending on size and hardware.
Getting Comparable Quotes
Always confirm that quotes specify: footing depth (for decks and fences), decking material by brand and product line, structural member sizes, permit inclusion, and all hardware. Without these, comparing prices is meaningless.
