Typical deck price ranges in Huntsville
- Pressure-treated wood deck: roughly $25–$45 per square foot installed. A 12×16 ft deck often lands around $5,000–$9,000.
- Composite deck (Trex, TimberTech, etc.): roughly $40–$70+ per square foot installed. The same 12×16 ft deck is commonly $8,000–$15,000.
- Deck repair: small board and railing repairs can be a few hundred dollars; structural repairs (joists, posts, footings) cost more.
- Railings: wood railings are the most affordable; composite, aluminum and cable railings add cost per linear foot.
These are general ranges, not quotes. Your price depends on the details below.
What changes the price of a deck
- Size and height: second-story decks need taller posts, more bracing and longer stairs.
- Material: composite costs more up front but needs far less maintenance than wood in North Alabama's humid summers.
- Site and soil: sloped lots and Huntsville's clay soil can require deeper or larger footings.
- Permits: the City of Huntsville and Madison County generally require a building permit for decks attached to the house or above a certain height.
- Extras: built-in benches, lighting, pergolas, covers and screened porches.
Wood vs. composite: which is cheaper long-term?
Wood is cheaper on day one. Composite usually wins over 10–15 years because it does not need yearly sanding, staining or sealing and resists rot and splintering. If you plan to stay in your home for a long time, composite or Trex is often the better value. See our composite deck installation and Trex deck installation pages.
