Enter your deck specifications to calculate the cost.
How It Works
Our deck cost calculator uses current material prices and average labor rates to estimate your project. We calculate costs based on your deck's square footage and factor in framing, footings, railing, stairs, and hardware.
Pressure-treated lumber is the most affordable option but requires regular maintenance. Cedar offers natural beauty and rot resistance at a moderate price. Composite decking costs more upfront but requires minimal maintenance over its 25+ year lifespan.
Labor typically accounts for 40-50% of total deck cost. Complex designs, multi-level decks, and difficult site conditions can increase costs. Always get multiple quotes from licensed contractors.
Frequently Asked Questions
How long does it take to build a deck?
A simple 12x16 deck takes 1-3 days for professionals. Larger or more complex decks with multiple levels, built-in seating, or intricate railing designs can take 1-2 weeks. Weather delays and permit inspections add time.
Do I need a permit to build a deck?
Most jurisdictions require permits for decks over 200 square feet or more than 30 inches above grade. Permits ensure your deck meets safety codes and typically cost $100-$500. Building without a permit can cause problems when selling your home.
Which decking material lasts longest?
Composite decking lasts 25-30+ years with minimal maintenance. Cedar lasts 15-20 years with proper sealing. Pressure-treated wood lasts 10-15 years but requires annual sealing. All materials require proper installation and drainage for maximum lifespan.
Can I build a deck myself?
Basic decks are achievable DIY projects if you're comfortable with carpentry. You'll save 40-50% on labor costs. Key challenges include proper footing placement, ledger board attachment, and building to code. Consider hiring for the foundation and doing decking yourself.
What adds value: a deck or a patio?
Wood decks typically recoup 65-75% of their cost at resale. Patios cost less but also add value. Choose a deck if you have a sloped yard, want to be at door level, or prefer wood aesthetics. Patios work better for flat yards and fire pit areas.
