A deck is one of the best ROI home improvements you can make — and one of the most variable in pricing. Material choices, height, complexity, and local permit requirements can push deck quotes from $5,000 to $30,000+ for similar-sized projects. QuoteScore helps you understand what's fair in your specific market.
Deck Pricing Varies Dramatically by Region
Lumber costs, permit fees, and labor rates vary significantly across the U.S. A deck in the Pacific Northwest faces different material costs than one in the Southeast. Your zip code unlocks locally calibrated benchmarks.
Understanding Deck Pricing in Your Market
Deck pricing has three major components: materials (the largest variable), labor (the largest local variable), and permits and inspections (varies widely by municipality). Material costs are fairly transparent — you can look up Trex or pressure-treated lumber prices at Home Depot. Labor and permits are where local knowledge matters.
In high-cost markets like Seattle, Denver, or any major Northeast city, deck labor runs $45-$80 per square foot just for installation. In lower-cost markets, the same labor is $20-$40/sq ft. Permit fees range from $100 in rural areas to $1,500+ in urban markets with complex inspection requirements. QuoteScore's regional pricing database accounts for all of this when benchmarking your specific quote.
Material Choices and What They Should Cost
Pressure-treated lumber is the budget option at $15-$25/sq ft installed. It requires staining every 1-3 years to prevent cracking and splitting. Budget option, but ongoing maintenance cost.
Cedar or redwood is a step up at $20-$35/sq ft installed. More attractive appearance, naturally resistant to moisture and insects, requires less maintenance than PT but still needs periodic sealing.
Composite decking (Trex, TimberTech, Azek) runs $30-$60/sq ft installed. Requires virtually no maintenance, looks excellent for decades, and comes with 25-year warranties. The premium pays for itself in maintenance savings over time.
Any quote should specify exactly which material, which brand, and which grade/product line. "Composite decking" without a brand is not a specification — product quality varies enormously between manufacturers and product tiers.
Deck Quote Red Flags
No permit included. Attached decks and elevated decks (over 30 inches) require building permits in nearly every U.S. jurisdiction. Permits cost $100-$1,500 but protect you from structural liability and home sale issues. A quote that doesn't mention permits is planning to build without them.
Footings not specified. Deck footings must go below the frost line for your area — the depth varies from 12 inches in Southern states to 48+ inches in Northern climates. Shallow footings on a frost-subject site will cause your deck to heave and become unsafe. Ask specifically about footing depth.
Vague material description. "Composite decking" with no brand, "pressure-treated lumber" with no grade — these are invitations for a downgrade to the cheapest available material after you've agreed to price. Require specific brand and product names before signing.
