The 2026 deck cost guide

Most homeowners spend between $4,500 and $15,000 on a new deck, which works out to roughly $30–$60 per square foot installed. The exact number depends on five things: size, material, height, location, and whether you DIY or hire a contractor.

Cost by material

Material is the single largest cost driver. See the full material comparison →

• Pressure-treated pine: $15–$25/sqft installed. The budget pick.

• Composite (Trex Enhance, TimberTech): $30–$60/sqft. Low maintenance, 25-year warranty.
• PVC / capped: $45–$65/sqft. Premium look, fully synthetic.
• Hardwood (Ipe, Mahogany): $50–$75/sqft. Premium and long-lasting.

How to save money on your deck build

1. Build off-season. Late winter and fall offer 10–20% better pricing. Read more →
2. Stick to a rectangle. Custom shapes add 15–25% in labor.
3. Choose entry-level composite instead of premium for similar long-term value.
4. DIY railings or stairs only — leave structural work to pros.
5. Get 3 quotes. Pricing varies wildly by contractor backlog.
