Built for the Hill Country

Outdoor projects here are not built like anywhere else.

San Antonio and the Texas Hill Country put real demands on an outdoor space. The right deck, pergola, or patio cover starts with planning for the conditions this region actually throws at it, then choosing materials that hold up for the long run.

  • Intense sun and heat

    San Antonio summers run long and hot. Material choice, surface temperature, and shade orientation decide whether a space is usable in August. We plan for the sun you actually get.

  • Slope and grading

    Hill Country lots are rarely flat. Multi-level decks, engineered footings, and proper grading turn a steep or awkward yard into level, usable outdoor living.

  • Drainage and runoff

    Hard Texas rain moves fast. We grade for positive drainage away from the house and plan runoff so a new patio or deck does not become a water problem later.

  • HOA and subdivision standards

    Stone Oak, Boerne, Fair Oaks Ranch, and most local subdivisions require architectural review. We design to those standards and prepare the submission so approval is not a gamble.

  • Wind exposure

    Open Hill Country lots catch real wind. Pergolas, patio covers, and railings are engineered and anchored for the gusts this region sees, not generic minimums.

  • Long-term material performance

    Texas UV, heat, and humidity swings are hard on outdoor materials. We guide composite, cedar, metal, and roof choices toward what actually lasts here.

Frequently asked

Deck, pergola & patio cover questions, answered.

Real answers about cost, permits, timeline, materials, and what San Antonio homeowners ask before they hire a deck builder.

How much does a custom deck cost in San Antonio?
Most San Antonio decks we build land between $18,000 and $65,000 depending on size, material, and elevation. Composite decks (Trex, TimberTech, Fiberon) sit at the higher end. Cedar and pressure-treated wood builds come in lower. Every Klema Builders quote is fixed-price, line by line, before we break ground.
How much does a pergola cost in San Antonio?
A custom pergola in San Antonio typically runs $9,500 to $35,000. Cedar pergolas start lower, powder-coated aluminum sits in the middle, and motorized louvered or bioclimatic pergolas (Azenco, Struxure) reach the top of the range. We give you a fixed quote after walking the lot with you.
What is the difference between a pergola and a patio cover?
A pergola is an open-roofed shade structure with slats, louvers, or a lattice top. A patio cover is a solid roof, often matched to your home roofline, that fully blocks rain and sun. If you want year-round dry shade, you want a covered patio. If you want filtered light and breeze, you want a pergola.
Do I need a permit or HOA approval for a deck or pergola in San Antonio?
Yes, in most cases. The City of San Antonio requires a permit for decks above a certain height and for any roofed structure. HOAs across Stone Oak, Alamo Heights, Boerne, and Helotes typically require ACC submission with stamped plans. Klema Builders handles every permit and HOA submission for you as part of the build.
How long does a deck or pergola build take?
Most decks take 2 to 4 weeks of on-site work once permits clear. Pergolas typically take 1 to 2 weeks. The full timeline from design consult to walk-through is usually 6 to 10 weeks, including HOA review. We give you a build calendar with weekly milestones at quote signing.
What deck materials hold up best in Texas heat and sun?
For long-term performance in San Antonio sun, capped composite decking (Trex Transcend, TimberTech AZEK, Fiberon Concordia) is the strongest choice. It resists fading, splintering, and mold. Premium cedar is a beautiful natural option that needs sealing every 2 to 3 years. We help you pick the right material for your shade exposure, budget, and maintenance tolerance.
Do you serve Boerne, New Braunfels, and the Texas Hill Country?
Yes. Klema Builders works across the greater San Antonio metro and the Texas Hill Country, including Boerne, Bulverde, Spring Branch, Helotes, Stone Oak, Alamo Heights, Schertz, Cibolo, Fair Oaks Ranch, Canyon Lake, New Braunfels, Seguin, San Marcos, Wimberley, Fredericksburg, and Kerrville.
What manufacturer warranties come with the materials you install?
We install materials with strong manufacturer-backed coverage that passes through to you on day one. Trex composite decking carries up to a 50-year limited warranty, TimberTech and Fiberon up to 30, Belgard pavers a lifetime warranty against material defects, and Azenco and Struxure pergolas carry their own multi-year structural warranties. Every product warranty is registered in your name at the walk-through.
