The Ranking
Our top 6 deck builders in Austin
A deck in Austin has to survive long, hot summers more than cold winters. Frost is rarely a factor here, so footing depth is driven by soil and load rather than a deep frost line. The residential code Austin follows calls for footings at least 12 inches below undisturbed ground, and many builders go deeper. East of I-35 and across much of the city, expansive clay swells after rain and shrinks in drought, which can tilt posts and pull a deck away from the house over a few seasons. West of MoPac and into the hills, crews often hit limestone close to the surface and need rock bits or pinned footings. Ask every builder how deep it sets footings in your soil, what the posts sit on, and how it handles a slope.
Material choice comes down to heat, upkeep and budget. Pressure-treated pine is the lowest-cost frame and board, western red cedar is common for boards and pergolas, and hardwoods such as Ipe show up around pools. Composite and PVC boards from TimberTech, Trex, AZEK and Deckorators cost more up front but skip yearly staining, and their makers back them with long fade and stain warranties. Composite can get hot in direct sun, so lighter colors, shade from a pergola or a patio cover, or an open-sided roof are worth pricing at the same time. Termites and ground moisture are hard on wood posts, so ask what the posts and joists are rated for and how they are kept off the soil.
Permits matter more for decks than for fences. Under the residential code Austin follows, a deck generally needs a building permit unless it is small, freestanding, no more than 30 inches above grade and does not serve an exit door, so most attached and raised decks need one. Confirm with the City of Austin Development Services Department, which also inspects footings and framing. Two code points come up on almost every job: a deck attached to the house must be bolted to a sound rim with a properly flashed ledger, and a deck surface more than 30 inches above grade needs a guard at least 36 inches tall with openings small enough that a 4 inch sphere cannot pass. Austin also protects larger trees, so footings or decks inside the root zone of a protected tree can need review before work starts.
Texas has no state licence for deck builders or general home improvement contractors, so no state board vouches for any company here, and the checks fall to you. Ask for a certificate of general liability insurance, get the board line, framing lumber, fasteners, footing depth, railing type and warranty written into the quote, and confirm who pulls the permit and books inspections. Electrical work for deck lighting or outlets must be done by a contractor licensed by the Texas Department of Licensing and Regulation. Many subdivisions, from Circle C to Avery Ranch, have HOA rules on deck height, materials and colors that need approval first. Before anyone digs, Texas law requires a call to 811 so buried utility lines are marked.
The six companies on this list include two fence and deck builders, two whole-exterior firms with outdoor living divisions, a design-build remodeler and a siding company that also builds decks and patio covers. Match the company to your job: a simple replacement deck, a composite deck with a pergola, or a deck folded into a larger remodel.
