Frequently Asked Questions
How much does it cost to build a deck in 2026?
The average cost to build a deck ranges from $4,000 to $15,000 for a standard 200-300 sq ft deck. Pressure-treated wood costs $25/sqft installed, composite runs $45/sqft, and premium Ipe hardwood can reach $65/sqft. Total cost depends on materials, size, shape, railing, and your region.
Is a composite deck worth the extra cost?
Composite decking costs 60-80% more upfront than pressure-treated wood ($45/sqft vs $25/sqft). However, composite requires almost no maintenance — no annual staining, no splinters, no rot. Over 20 years, composite typically costs less when you factor in the $500-$800 you'd spend staining a wood deck every 1-2 years. Composite also lasts 25-30 years vs 15-20 for wood.
What is the cheapest deck material?
Pressure-treated pine is the cheapest decking material at about $25/sqft installed. For a 280 sq ft deck (14×20), that's roughly $7,000. Cedar costs 40% more at $35/sqft, while composite runs $45/sqft. If you go DIY with pressure-treated wood, materials alone run about $10/sqft.
How much does deck railing cost?
Deck railing costs $35-$120 per linear foot installed depending on material. Wood railing is cheapest at $35/lf, composite runs $50/lf, aluminum is $60/lf, cable railing costs $85/lf, and glass panels are the most expensive at $120/lf. A typical 280 sq ft deck needs about 50-60 linear feet of railing.
Does a deck increase home value?
Yes — a wood deck recoups about 83% of its cost at resale, while composite decks offer about 68% ROI. A $15,000 wood deck typically adds $12,000-$13,000 to home value. ROI is highest in warmer climates and areas where outdoor living space is in demand.
Do I need a permit to build a deck?
Most cities require permits for decks that are attached to the house or more than 30 inches above ground. Permits typically cost $150-$500. Ground-level floating decks under 200 sq ft may be exempt in some jurisdictions. Always check local building codes before starting.
Can I build a deck myself to save money?
DIY deck building can save 50-60% on labor costs. A 280 sq ft pressure-treated deck costs about $7,000 professionally but only $2,800-$3,500 in materials for DIY. However, you'll need carpentry skills, proper tools, and 3-5 weekends of work. Mistakes in framing or footings can be costly to fix and may affect structural safety.
