Terrain and soil
North of Loop 1604 the ground is thin soil over Edwards limestone and caliche, so deck piers are often drilled into rock rather than dug.
MoreLess
South and east of downtown the Blackland clay swells and shrinks with the seasons, which is why footing depth and ledger flashing matter more than they do in a dry-rock yard. Mature live oaks and pecans are common inside Loop 410 and shape where posts can go.
Permits and HOA review
Inside city limits the City of San Antonio Development Services Department typically requires a building permit for a deck that is attached to the house, larger than 300 square feet or more than 30 inches above grade, plus an electrical permit for lighting; the city code and Information Bulletin 151 set the 300 square foot line, an older DSD web page still shows 200, so confirm the threshold for your lot with the city.
MoreLess
Master-planned neighborhoods such as Stone Oak, Alamo Ranch, Sonterra and The Dominion run an architectural review before work starts. Alamo Heights, Terrell Hills and Olmos Park are separate cities with their own permit desks.
Why it matters
The right pier depth and fastener spec change within a few miles here.
MoreLess
A deck engineered for rock in Stone Oak is not the deck that survives clay on the South Side, and a permit filed with the wrong city is a lost month. Klema Builders scopes the footing and the paperwork to the exact address before the price is written.

How a job runs
Step 1: Consult
We meet at your home, walk the backyard, and listen to how you actually want to use the space. A real conversation about the project, with no pressure and no hard sell.
Step 2: Design and scope
We sketch the layout in place, talk through structure and elevation, and define a clear written scope so everyone knows exactly what is being built.
Step 3: Materials
We bring real material samples to your home and compare them in your own light. Composite versus cedar, roof options, railings, and finishes, chosen with you, not guessed.
Step 4: Permits and HOA
When your project needs HOA approval or a city permit, we prepare the submission package and handle the back-and-forth so you are not chasing paperwork.
Step 5: Build
A tight, trusted crew builds the project on a written schedule. You get regular progress updates, so you always know what is happening and what comes next.
Step 6: Walk-through
We walk the finished project with you, complete a punch list together, and hand over every manufacturer warranty registered in your name.
Common questions
Does Klema Builders build custom decks in San Antonio, Texas?
Klema Builders is a custom deck builder in San Antonio, Texas, working in wood (cedar, ipe, pressure-treated), composite (Trex, TimberTech, Fiberon), and full multi-level designs, and serving San Antonio, the Texas Hill Country and the I-35 corridor to Austin. Custom deck builds across every neighborhood inside Loop 1604 plus Stone Oak, Alamo Heights, and Helotes. A 400 sq ft composite deck is built in 3 to 6 weeks after permits clear and quoted fixed-price, line by line, after a free in-home consult. HOA submissions and permits handled, with manufacturer warranties registered in your name at the walk-through.
How much does a custom deck cost in San Antonio?
A 16x30 basic wood deck with handrails in San Antonio starts at $6,500, labor and materials included. That is a 16 ft by 30 ft (480 sq ft) deck in economy-grade wood with no upgrades (no composite boards, lighting, multi-level framing or built-ins), with handrails, built and installed. The final number depends on the decking material, the height above the ground, stairs, railing style, permits and HOA review. Every job gets a written fixed-price quote, line by line, within 3 to 5 business days after a free in-home consult.
What wood do you use for decks in San Antonio?
Wood decks in San Antonio are built with western red cedar, ipe, or pressure-treated southern yellow pine. Cedar carries the warm, traditional Hill Country look, with hand-cut decorative ends, sanded by hand, and sealed for Texas UV. Ipe is the hardwood option for a 30-plus year lifespan, oiled annually. Pressure-treated pine is the framing standard for every Klema deck. Custom deck builds across every neighborhood inside Loop 1604 plus Stone Oak, Alamo Heights, and Helotes. Stainless and coated fasteners survive local humidity swings, and we flash every ledger connection to prevent the slow rot that starts where the deck meets the house.
Do you build composite decks in San Antonio?
Yes. We build composite decks in San Antonio with Trex, TimberTech, and Fiberon. Surface temperature, UV stability, and structural shrinkage are the three Texas-specific failure points we engineer around. We compare board colors in your own sun at the consult, choose heat-rated capped composites, and specify stainless or coated fasteners. Lighter composite colors and modern capped boards run cooler than dark first-generation composite. Manufacturer warranties pass through to you on day one: Trex up to 50 years, TimberTech up to 50, Fiberon up to 30.
Do you build multi-level and pool decks in San Antonio?
Yes. Most San Antonio backyards benefit from at least two levels. A platform off the back door for the dining table and lounge seating, stepping down to a larger entertaining tier with seating and a fire feature. We engineer stairs, lighting, and railing heights to current IRC code in every jurisdiction we serve. Pool decks get slip-resistant surfaces, generous coping detail, and engineered drainage transitions. Every multi-level deck we build is custom-designed to your lot, your view corridor, and the way you actually live outside.
Do you handle HOA submissions and permits?
Yes, every time. We prepare the architectural review package, the site plans, and the material specs, and submit on your behalf. We also pull all required deck and electrical permits and coordinate inspections. Permitting is a line item in your quote.
More questions (4)Fewer questions
How long does the build take from quote to walk-through?
Composite or cedar decks take 3 to 6 weeks from signed contract to walk-through once permits clear. Multi-level decks or pool decks run 6 to 10 weeks. We provide a written schedule in your contract.
Will a composite deck get too hot in Texas summers?
Dark first-generation composite can get hot in direct August sun. Lighter colors and modern capped boards run cooler, and we compare samples in your own sun before you commit.
Can you build on a sloped Hill Country lot?
Yes. Multi-level decks on caliche, limestone, and clay soils are normal terrain for us. We engineer the pier depth and beam spans for your specific lot, with stamped drawings if your jurisdiction requires them.
What manufacturer warranties come with the materials you install?
Manufacturer warranties on composite decking pass through to you on day one: Trex up to 50 years, TimberTech up to 50, Fiberon up to 30. Every manufacturer warranty is registered in your name at the walk-through.
