A deck is one of the best home improvement investments, typically returning 60–80% of its cost in added home value while giving you years of outdoor living enjoyment. Here's how to budget your deck project accurately.
Average Deck Costs
| Deck Type | Cost per Square Foot | Typical Total Cost |
|---|---|---|
| Pressure-treated wood | $15–$25 | $5,000–$15,000 |
| Cedar or redwood | $25–$35 | $8,000–$20,000 |
| Composite decking | $30–$60 | $12,000–$35,000 |
| PVC decking | $35–$70 | $15,000–$40,000 |
| Hardwood (Ipe, Teak) | $25–$50 | $10,000–$30,000 |
Decking Material Comparison
| Material | Lifespan | Maintenance | Best For |
|---|---|---|---|
| Pressure-treated pine | 15–20 years | Annual sealing | Budget projects |
| Cedar | 20–30 years | Staining every 2–3 years | Natural look |
| Composite | 25–30 years | Minimal — occasional cleaning | Low maintenance |
| PVC | 30+ years | Very minimal | Durability |
Additional Deck Costs
- Railing — $30–$100 per linear foot depending on material
- Stairs — $400–$1,500 per staircase
- Footings and posts — $100–$200 each (need one every 6–8 feet)
- Permit — $200–$1,000 depending on size and location
- Lighting — $500–$2,000 for deck lighting
Pro Tip: Composite decking costs 2–3x more upfront than pressure-treated wood, but saves money long-term — no staining, no sealing, no splinters, and it won't warp or rot.

Most jurisdictions require a permit for any deck over 30 inches off the ground or over a certain square footage (often 200 sq ft). Always check with your local building department. An unpermitted deck can create issues during home sales and may not meet safety codes.
