Wood vs. Composite — Which Is Right for San Antonio?
Pressure-Treated Wood
The most common choice in San Antonio. Less expensive upfront, looks great when stained, and handles Texas weather well when maintained. Requires re-staining every 2–3 years to stay protected. Lifespan: 15–25 years with proper upkeep.
Cedar or Redwood
Naturally rot-resistant and looks beautiful. Costs more than pressure-treated pine but less maintenance. A good middle ground for homeowners who want natural wood without constant upkeep.
Composite (Trex, TimberTech, etc.)
Higher upfront cost but very low maintenance — no staining, no splinters, and holds up well to UV in San Antonio summers. Lifespan: 25–50 years. If you're staying in your home long-term, composite often wins on total cost of ownership.
What's Included in a Deck Build?
A properly built deck includes:
- Footings — Concrete piers drilled below the frost line (required by San Antonio code)
- Framing — Pressure-treated structural lumber, beams, and joists
- Decking boards — Surface material (wood or composite)
- Railing system — Required for decks over 30 inches off the ground
- Stairs — At least one stair access point per code
- Ledger board connection — Where the deck attaches to the house (must be done right to prevent water intrusion)
Do You Need a Permit for a Deck in San Antonio?
Yes, in almost all cases. San Antonio requires a building permit for decks that are attached to the home or over 200 square feet. The permit process ensures proper footing depth, structural sizing, and railing height per IRC code.
At MrRoyLLC, we pull all required permits and schedule inspections. We do not build decks without permits — it protects you at resale and keeps your homeowner's insurance valid.
How Long Does Deck Construction Take?
- Permit approval: 1–3 weeks in San Antonio
- Construction time: 3–7 days for most residential decks
- Inspection and final sign-off: 1–2 days after construction
Total timeline from project start to finished deck: typically 3–5 weeks.
What Adds Cost to a Deck Project?
- Multi-level or angled designs — More cuts, more waste, more labor
- Built-in seating or planters — Add $500–$2,000
- Pergola or roof structure — Significant addition ($4,000–$12,000+)
