Deck Building & Installation
A well-built deck extends your living space outdoors, creating a perfect area for entertaining, relaxing, and increasing your home's value. From classic pressure-treated wood to low-maintenance composite materials, today's decking options offer durability and beauty for every budget.
Decking Material Options
The material you choose for your deck affects appearance, maintenance, longevity, and cost. Here are the most popular options:
- Pressure-treated wood: The most affordable option at $15-$25 per sq ft installed. Requires staining every 2-3 years. Lasts 15-20 years with maintenance. Warm, natural appearance.
- Cedar or redwood: Natural beauty and rot resistance at $20-$40 per sq ft installed. Requires annual sealing. Lasts 20-30 years.
- Composite decking: Made from wood fibers and plastic. Low maintenance with no staining required. Costs $25-$45 per sq ft installed. Lasts 25-30+ years. Leading brands include Trex, TimberTech, and Fiberon.
- PVC decking: Fully synthetic, 100% moisture-proof. Lightest weight and most resistant to staining. Costs $30-$50 per sq ft installed. Lasts 30+ years.
Composite and PVC decks have higher upfront costs but lower lifetime costs when you factor in the elimination of annual staining and sealing. Over 20 years, a composite deck often costs less than a wood deck that requires regular maintenance.
Deck Building Costs
Deck costs depend on size, material, height, complexity, and features like railings, stairs, and built-in seating. For a typical 300-400 sq ft deck:
- Pressure-treated wood deck: $4,500-$10,000
- Composite deck: $7,500-$18,000
- Cedar deck: $6,000-$16,000
- Multi-level or complex design: Add 30-50% to base costs
Railings add $20-$60 per linear foot. Stairs add $50-$150 per step. Built-in benches, planters, and pergolas add to the total. Elevated decks (second story) require additional structural support and cost 50-100% more than ground-level decks.
Most municipalities require permits for decks. Permit costs are $100-$500 and ensure the deck meets building codes for structural safety. Your contractor should handle all permitting.

Deck construction involves structural engineering, carpentry, and code compliance. A poorly built deck is a safety hazard. When choosing a builder:
- Structural knowledge: The contractor must understand load calculations, post spacing, beam sizing, and joist span tables to build a safe deck
- Code compliance: Building codes dictate railing height, stair dimensions, ledger board attachment, and post-to-footing connections. Non-compliant decks are safety hazards and may need to be rebuilt
- Portfolio and references: Ask to see recent deck projects similar to your design. If possible, visit a completed project to inspect the quality of work
- Detailed plans: Before construction begins, you should have scaled drawings showing dimensions, materials, footings, and structural details

A standard ground-level deck takes 1-2 weeks to build. Elevated decks, multi-level designs, or projects with custom features take 2-4 weeks. Add 1-3 weeks for permit processing before construction begins.
Yes. A wood deck recoups approximately 65-75% of costs at resale. A composite deck recoups 60-70%. Beyond resale value, a deck significantly expands usable living space and improves buyer appeal.
Almost always, yes. Most municipalities require permits for any deck that is attached to the house, elevated more than 30 inches above grade, or larger than 200 sq ft. Your contractor should handle permitting.
Composite is better for low maintenance and longevity. Wood is better for initial budget and natural aesthetics. If you dislike annual staining and sealing, composite pays for itself over time through eliminated maintenance costs.
