What Drives Deck and Fence Costs?
Deck and fence costs — $13,000 to $38,000 for a complete deck, $2,700 to $12,000 for a typical 150-foot fence — reflect the material choices, size, and site conditions of each specific project.
Deck Height and Foundation
A ground-level or low deck (under 18 inches above grade) uses simple footings and requires less structural support — a straightforward build. A raised deck (3 to 10+ feet above grade) requires: deeper concrete footings (typically below the frost line — 24 to 48 inches deep depending on climate), larger beams and posts, diagonal bracing for lateral stability, and often a more complex permit process including engineering review. A raised deck costs 20 to 40 percent more per square foot than a ground-level deck of the same material and size. For a second-story deck: add $5 to $15 per square foot over a comparable first-level deck for the additional structural requirements.
Stairs and Railing
Stairs and railing are among the most labor-intensive elements of deck construction relative to area. A simple stair run (3 to 5 steps): $500 to $1,500. A full stair run to grade (6 to 12 steps): $1,500 to $4,000. Railing: $40 to $120 per linear foot installed depending on material — pressure-treated wood and vinyl at the low end, composite and aluminum at the top. A 40-linear-foot railing: $1,600 to $4,800. Cable railing (horizontal stainless cables rather than balusters) provides an open, modern look at $85 to $180 per linear foot installed. Glass panel railing: $200 to $500 per linear foot installed. (For more on this, see Deck Material Comparison: Wood vs. Composite.)
Fence Terrain and Gate Count
A flat, obstacle-free yard with clear fence line access is the minimum-cost fencing scenario. Slopes: a stepped fence (panels installed level in steps) vs. a racked fence (panels that follow the slope) — stepped fences are simpler but leave gaps at the base; racked fences follow the slope but require more skilled installation. Gates: $200 to $1,000 each for a standard wood or vinyl gate, $500 to $2,000 for a double gate or a gate with hardware for a driveway. Post removal (if replacing an existing fence): $25 to $50 per post for removal and disposal of posts set in concrete. (For more on this, see Hidden Costs of Deck and Fence Installation.)
Material Grade
Within the composite decking category: entry-level composite (Trex Enhance, TimberTech AZEK Harvest) at $3 to $5 per linear foot for the boards vs. premium composite (Trex Transcend, TimberTech AZEK Vintage) at $5 to $9 per linear foot. The premium products have more realistic wood-grain texture, better fade and stain resistance, and longer warranties (30 to 50 years on some premium lines). On a 400-square-foot deck: this material difference adds $1,700 to $3,400 for the decking boards alone, since 400 square feet takes roughly 850 linear feet of 5.5-inch board.
Deck and Fence Cost at a Glance
| Cost Factor | Typical Range | Notes |
|---|---|---|
| Wood deck | $40 to $70 per square foot | installed — pressure-treated, complete with footings, framing, railings, and steps |
| Composite deck | $55 to $100 per square foot | — low-maintenance and durable; cellular PVC and tropical hardwood run $70 to $120 |
| Fence | $18 to $80 per linear foot | — varies by material, from chain-link to wood to vinyl |
| Overall range | $13,000 to $38,000 | , averaging $20,000 for a complete 16 by 20 foot deck; a 150-foot fence runs $2,700 to $12,000 |

Planning Your Project Budget
The cost ranges in this article are based on industry data and are intended as planning benchmarks, not fixed prices. The actual cost for your project depends on your specific home, your local labor market, the current price of materials, and the scope the contractor confirms after a site inspection.
Always get at least two written quotes on equivalent defined scope before committing to any home services project. Wide price variation between quotes usually reflects differences in material quality, scope completeness (what is included and what is not), or contractor overhead and experience level rather than simple price competition.
Use the cost data in this article to ask better questions during the quoting process: What material is included? What does that per-square-foot or per-linear-foot rate include and exclude? Are permits, cleanup, and disposal included? What is the warranty on labor? These questions turn a quote into a comparable basis for decision-making. (For more on this, see Questions to Ask Before Building a Deck or Fence.)
Working With a Contractor on This Project
Getting the right outcome on any home services project starts before the work begins. A few consistent practices make the difference between a smooth project and a frustrating one.
Get at least two or three quotes. A single quote gives you no basis for comparison. Two or three quotes reveal the market rate for the work, expose scope differences between bidders, and let you assess contractor communication quality before any commitment is made. The lowest bid is not automatically the best value if the scope is thin or the materials are underspecified.
Ask for licenses and insurance before work starts. Verify current general liability insurance and, for any work involving workers on your property, workers compensation coverage. Licensing requirements vary by state and trade; confirm the specific requirements in your jurisdiction. A licensed contractor who carries appropriate insurance protects both parties if something goes wrong during the project.
Get the scope in writing. A written proposal that specifies materials, labor scope, timeline, what is included (permits, cleanup, disposal), and warranty terms is the foundation of a professional engagement. Verbal agreements on any of these points invite misunderstanding. For any project over $500, written scope is non-negotiable.
Clarify the payment schedule upfront. A reasonable payment schedule ties major payments to project milestones: a deposit at signing, a payment at material delivery or project start, and a final payment at completion after a walkthrough confirms satisfaction. A contractor who requires full payment upfront before work begins is a red flag in any trade.
