Deck Cost Breakdown
Deck cost varies dramatically by material choice. Pressure-treated pine is the budget option at $2–4 per square foot for materials. Composite decking (Trex, TimberTech, Fiberon) runs $4–12 per square foot but eliminates staining and maintenance for 25+ years. Hardwood (ipe, mahogany) costs $8–20 per square foot but lasts 40+ years.

Labor adds $15–30 per square foot on top of materials. A 200 sq ft deck: $2,400–4,800 materials (PT wood) or $4,000–8,000 (composite), plus $3,000–6,000 labor. DIY saves the labor cost but requires tools and building code compliance — most jurisdictions require a permit for any deck over 30 inches above grade.
