How much does it cost to build a deck?

A basic pressure-treated wood deck costs $15-$25 per square foot for materials, with total project costs (including labor) ranging from $4,000-$12,000 for a standard 200 sq ft deck. Composite and PVC decks cost $30-$50 per sq ft for materials. Total costs depend on size, material, height, and add-ons like railings and stairs.

Which deck material is the best value?

Pressure-treated wood has the lowest upfront cost ($15-$25/sq ft) but requires annual maintenance (staining/sealing). Composite decking ($30-$45/sq ft) costs more initially but requires virtually no maintenance and lasts 25-50 years. Over a 25-year period, composite often costs less when maintenance is factored in.

Do I need a permit to build a deck?

Most municipalities require a building permit for decks that are more than 30 inches above grade, attached to the house, or over a certain size (often 200 sq ft). Ground-level, freestanding decks may be exempt. Always check your local building department. Permit costs typically range from $100-$500.

How long does a deck last?

Pressure-treated wood decks last 10-15 years with proper maintenance (annual staining/sealing). Cedar decks last 15-20 years. Composite decks last 25-50 years with minimal maintenance. PVC decks can last 30-50+ years. Proper installation, drainage, and maintenance significantly affect lifespan.

How long does it take to build a deck?

A simple ground-level deck (200-300 sq ft) can be built in 1-3 days by a professional crew. A larger elevated deck with stairs and railings typically takes 1-2 weeks. Complex multi-level decks with built-in features can take 2-4 weeks. Add time for permitting and material delivery.

Is it cheaper to build a deck yourself?

DIY deck building can save 30-50% on labor costs, which typically make up $8-$22 per square foot of the total. However, DIY is only recommended if you have construction experience. Mistakes can be costly and compromise structural safety. Many composite manufacturers void warranties if not professionally installed.
