  • Composite decks (Trex, TimberTech) cost $15,000–$35,000 but require minimal maintenance

Wood vs. Composite: The Austin Deck Decision

Pressure-treated wood is the budget-friendly entry point. It builds well, looks natural, and costs $8,000–$20,000 for a typical 12×20 ft deck in Austin. The catch: Austin's brutal summers fade and crack untreated wood fast. Plan on annual staining and periodic board replacement after 8–10 years.

Composite decking (Trex, TimberTech, Fiberon) costs more upfront — $15,000–$35,000 for the same footprint — but requires almost no maintenance. It won't fade, crack, or splinter, and carries 25–30 year warranties. In Austin's heat, composite is increasingly the preferred choice for homeowners who don't want annual deck maintenance.

Cedartone and Ipe (hardwood) are premium wood alternatives at $20,000–$40,000+ — beautiful but require specialized care.

Deck Cost by Size

**Small deck (10×12 ft, ~120 sqft):** $6,000–$14,000. Good for a single outdoor table and chairs. Common on smaller East Austin lots.

**Medium deck (12×20 ft, ~240 sqft):** $10,000–$22,000. The most common size in Austin — fits a full outdoor dining setup. Composite at this size runs $18,000–$22,000.

**Large deck (16×24 ft or larger, 380+ sqft):** $18,000–$40,000+. Often combined with a pergola or shade structure. Multi-level decks add 20–30% to cost due to additional framing.

Add-ons that Austin homeowners commonly include: built-in bench seating ($800–$2,500), pergola or shade cover ($4,000–$12,000), outdoor lighting ($500–$2,000), outdoor kitchen rough-in ($1,500–$4,000).

Austin Deck Permits and the Process

Most decks in Austin require a building permit. The threshold is generally any deck attached to the house or over 30 inches above grade — which covers nearly every project we build.

Permit fees run $150–$400 in Austin. The City of Austin's turnaround is typically 2–4 weeks for residential deck permits. We submit the permit application as part of your project — you don't have to navigate the city portal.

HOA approval is separate from city permits. If your neighborhood has an HOA, we can help you prepare the documentation they need, but HOA timelines vary and are outside our control.

Maintenance Reality for Austin Decks

Wood decks in Austin need annual cleaning and staining/sealing to survive the heat and UV exposure. Budget $300–$600 per year for a professional cleaning and seal coat, or do it yourself with $80–$150 in materials.

Neglected wood decks deteriorate fast in Texas. We've seen 5-year-old decks that needed full board replacement because they were never stained. If you don't want the maintenance commitment, composite is the honest recommendation.

Composite decks need occasional cleaning (power wash once a year) — that's essentially it. The higher upfront cost buys you back years of weekends.

Common Questions

Frequently Asked Questions

Do I need a permit for a deck in Austin?

Yes, in almost all cases. Any deck attached to the house or over 30 inches above grade requires a building permit in Austin. Permits cost $150–$400 and take 2–4 weeks. ATX Construction handles the permit application as part of your project.

How long does deck construction take?

A standard 240 sqft deck takes 3–5 days of active construction. Total project timeline from signed contract to completion is typically 3–5 weeks, accounting for permit approval and material delivery. Composite decking materials sometimes have 1–2 week lead times.

Is composite or wood better for Austin weather?

Composite holds up significantly better in Austin's heat and UV exposure. Wood decks fade, crack, and require annual staining to stay looking good. If you want minimal maintenance, composite is the right call. If budget is the primary driver, pressure-treated wood with a commitment to annual care is a solid option.

My deck is damaged — should I repair or replace?

If the structural frame (posts, joists, beams) is solid and less than 40% of the boards need replacement, repair usually makes sense. If the frame is rotting or more than half the boards are compromised, a full replacement is better value. We'll assess both scenarios in your estimate so you can make the call.
