Wood decks typically last 10 to 20 years depending on climate and maintenance. Composite decks last 25 to 30 years. Minor repairs cost $500 to $2,000, while a full replacement runs $3,000 to $10,000 or more. The right choice depends on the extent of the damage and the age of your deck.
A well-maintained deck adds valuable outdoor living space to your San Antonio home and can be a strong selling point for buyers.
Deck Lifespan by Material
Pressure-treated pine decks last 10 to 15 years in Texas's humid climate with regular sealing and maintenance. Cedar and redwood decks last 15 to 20 years. Composite decking lasts 25 to 30 years with minimal maintenance. PVC decking can last 25 years or more and is completely waterproof. The material you choose determines both the upfront cost and long-term maintenance requirements.
Repair vs Replace: How to Decide
If the deck structure, including joists and posts, is still sound but individual boards are cracked or splintered, repairing by replacing those boards is cost-effective. If the ledger board is rotting, the posts are sinking, or the deck feels bouncy and unsafe, full replacement is the safer choice. A professional inspection can help you decide. In general, if your deck is more than 15 years old and needs significant repairs, replacement is worth the investment.
Deck Repair and Replacement Costs
Minor repairs like replacing a few boards or railing sections cost $500 to $2,000. Structural repairs that involve replacing joists or posts run $1,500 to $4,000. A full deck replacement with pressure-treated wood costs $3,000 to $7,000. Composite deck replacement runs $6,000 to $10,000 or more. Adding features like built-in seating, stairs, or pergolas increases the cost.
Choosing the Right Deck Material
Pressure-treated wood is the most affordable option but requires annual sealing or staining. Composite decking costs more upfront but never needs staining and resists splinters and rot. For San Antonio's climate, composite is a popular choice among homeowners who want a low-maintenance outdoor space. PVC decking is best for areas near pools or in wet conditions.
