Material Analysis, Cost per Square Foot by Decking Type
Pressure‑Treated Lumber, $25–45 per Sq Ft Installed
Characteristics
Pressure‑treated southern yellow pine is the most common deck material in the US. It offers low upfront cost and wide availability. Annual sealing is required. Within 5–7 years, cracking, warping, and raised grain typically appear.
Cedar and Redwood – $35–65 per Sq Ft Installed
Characteristics
Cedar provides natural rot and insect resistance with a distinct aroma. Redwood offers premium aesthetics. Both are softer than PT and prone to surface damage from heavy objects. Redwood prices on the West Coast have increased substantially.
Composite Decking – $45–80 per Sq Ft Installed
Characteristics
Composite materials (wood fibers and recycled plastic) require no sealing, staining, or sanding. Surface temperatures can exceed wood in direct sunlight. Hidden fastening systems add $1–3 per square foot.
Premium PVC – $60–100+ per Sq Ft Installed
Characteristics
PVC decking (e.g., Azek, TimberTech premium lines) is 100% synthetic and completely resistant to moisture and rot. It can be painted and is available in many colors. In high‑cost markets such as Boston, installed prices may reach $140 per square foot.
Labor Cost Analysis, Hourly and Per‑Square‑Foot Rates
Regional Variation
Labor is the primary driver of differences in deck building cost per square foot across US markets. The same deck specifications can vary by 100% or more depending on location.
Low‑Cost Labor Markets
Midwest and South (e.g., rural Ohio, Missouri): Total installed cost (materials + labor) ranges from $35 to $55 per square foot for basic decks.
High‑Cost Labor Markets
California, Northeast, and Seattle metropolitan areas: Labor alone accounts for $50 to $80 per square foot before materials are added.
Ancillary Costs, Permits, Railings, Stairs, and Site Work
Six Common Budget Extenders
The following items are frequently omitted from initial quotes but materially affect the final deck building cost per square foot.
- Demolition and disposal of existing deck: $3–8 per square foot
- Building permits: $200–1,000 flat fee (not per square foot)
- Ground preparation (grading, excavation, gravel): $2–10 per square foot
- Railings (basic to premium): $10–40 per linear foot
- Stairs and landings: $1,500–5,000 per set
- Hidden fasteners for composite decking: $1–3 per square foot
