01 / 05

Cedar, aluminum, louvered, or bioclimatic.

Cedar pergolas remain the most popular Hill Country choice for their warmth and craftsmanship. We hand-cut, sand, and seal every cedar member, and use stainless connectors that survive San Antonio humidity swings.

Powder-coated aluminum delivers maintenance-free performance with crisp lines that suit modern and transitional homes. Louvered systems add motorized control, and bioclimatic systems from Azenco close into a fully sealed outdoor room for genuine year-round use.

02 / 05

Attached or freestanding, modeled side by side.

Attached pergolas tie into the home roofline, deliver deeper shade, and typically save 10 to 20 percent on cost. Freestanding pergolas can sit anywhere on the property and avoid any modification to your existing roof. We walk you through both options on site with material samples, and flag the proposed footprint on the ground so you can stand inside it before you commit.

03 / 05

Motorized louvered and bioclimatic, for year-round use.

Louvered systems open and close at the tap of a button, with rain sensors that close automatically when the weather turns. Bioclimatic units add side screens, wind sensors, integrated heaters, and ambient lighting. With sealed gutters and full perimeter screens, your patio works as a den from October through May and an open-air dining room the rest of the year.

04 / 05

HOA submissions and ACC packages, handled by us.

We prepare the architectural review submission, including site plans, material specs, and a project narrative. Average approval time in our top neighborhoods is 2 to 4 weeks. We respond to board comments on your behalf and notify you only when something requires a decision from you.

05 / 05

Lighting, screens, and the details that change everything.

We map out the lighting plan during your consultation, so post-cap lights, low-voltage step lighting, and integrated overhead fixtures all line up with how you actually use the space. MagnaTrack motorized screens drop in 30 seconds and transform an open pergola into a mosquito-proof family room.

Questions homeowners ask us

Frequently asked questions

Does Klema Builders build custom pergolas in San Antonio?
Klema Builders is a custom pergola builder serving San Antonio, Texas and the surrounding Texas Hill Country. The team designs and installs cedar, powder-coated aluminum, motorized louvered, and Azenco bioclimatic pergolas across the greater San Antonio metro. Cedar pergolas typically run $4,000 to $12,000 installed. Motorized louvered and bioclimatic systems range from $18,000 to $70,000 plus. Every project includes HOA submissions, city permits, a fixed-price quote line by line, and manufacturer warranties from Azenco, Struxure, and our cedar suppliers registered in your name at handoff.
How much does a pergola cost in San Antonio?
Cedar pergolas in San Antonio run roughly $4,000 to $12,000 installed. Powder-coated aluminum lands at $8,000 to $18,000. Motorized louvered systems run $18,000 to $45,000, and Azenco bioclimatic units start around $25,000 and can exceed $70,000 with screens and lighting.
Should I attach my pergola to the house or freestanding?
Attached pergolas are typically 10 to 20 percent cheaper, integrate with the house roofline, and provide deeper shade. Freestanding gives you placement freedom and avoids any tie-in to existing roofing. We walk you through both options on site with material samples so you can choose with confidence.
Are louvered pergolas worth the price difference?
If you want to use your patio in light rain, blazing sun, and across all four seasons, yes. Motorized louvers open for full sun, close for rain protection, and integrate with rain sensors. Bioclimatic units like Azenco add wind sensors and side screens for genuinely year-round use.
How long does a custom pergola take to build?
Cedar pergolas typically take 2 to 4 weeks from contract to completion. Aluminum and louvered systems run 4 to 8 weeks depending on lead times. We confirm material availability before the contract so the schedule is realistic.
Do pergolas need HOA approval in San Antonio?
Almost always, yes. Stone Oak, Alamo Ranch, Cibolo, Fair Oaks Ranch, and Timberwood Park all require submissions. We prepare and submit the package on your behalf as part of the standard scope.
Will a pergola provide enough shade in Texas?
A standard open-rafter pergola provides about 40 percent shade at noon. We design the rafter spacing and orientation based on your sun path, and can add shade cloth, sliding canopies, or louvers to dial it up to 100 percent.
Can I add a pergola to an existing concrete patio?
Yes. Existing concrete slabs at least four inches thick can host most cedar or aluminum pergolas with surface-mount or core-drilled anchors. We core test the slab during the consultation to confirm.
What is a bioclimatic pergola?
A bioclimatic pergola has a motorized louvered roof and side screens that respond to weather. Open the louvers for sun, close them for rain. Run the screens to block sun, wind, or insects. The system seals tight enough to use as a year-round outdoor room.
