Commissioning a stained glass panel is a journey — one that begins long before a single piece of glass is cut. When we create custom stained glass in San Antonio, we guide each client through every stage, from the first concept sketch to the moment the finished panel is set into its frame. A clear, deliberate process is what separates a panel that looks beautiful on paper from one that performs gracefully for decades in South Texas light and humidity.

Why a Guided Commission Process Matters in South Texas

San Antonio is a city where history and climate sit side by side. The Alamo City’s landmarks — including the San Fernando Cathedral, founded in 1731 with stained glass added in 1920 — remind us that well-made glass can outlast generations. But San Antonio’s high UV index and hot, humid summers also accelerate wear on building materials, which means a custom panel has to be designed for its specific location from the very first sketch. That is why we never treat a commission as a single creative leap — we break it into clear stages, each one giving the client a chance to weigh in before we move forward.

The Consultation: Reading Light, Space, and Intent

Every project starts on site. During the initial consultation, we study how light moves through the space across the day and through the seasons — a window facing the Riverwalk’s morning glare behaves very differently from one shaded by live oaks in Alamo Heights. We also listen carefully to intent: is the panel meant to honor a congregation’s story, brand a commercial lobby, or bring character to a private residence in Bexar County? These are the conversations that shape every decision that follows in a custom stained glass in San Antonio commission.

From those conversations we gather measurements, structural notes, and design goals, and we reference the client’s existing architecture, because a custom panel should feel like it belongs to the building, not dropped in from somewhere else.

From Concept Sketch to Approved Design

Next comes the concept sketch — the first time the project becomes visible. We translate the consultation notes into hand-drawn renderings that show composition, color placement, and proportion relative to the opening. Clients often see two or three directions before we settle on the one to refine. This sketch phase is, in many ways, the heart of any custom stained glass in San Antonio project, because it is where intent becomes image.

Once a direction is chosen, we develop it into a full-scale cartoon — the working drawing that will guide fabrication. At this stage we confirm:

  • Overall dimensions and orientation within the frame
  • The balance of color, clear, and textured glass
  • Lead line rhythm and structural reinforcement points
  • How the panel will read from both near and far, inside and out

Nothing moves into fabrication until the client signs off on the cartoon. That approval is the hinge between concept and craft, and it prevents costly surprises later in the build.

Selecting Glass for San Antonio’s Climate

Material selection is where a design either survives or struggles in South Texas. Because San Antonio’s UV exposure and humidity stress both glass and lead over time, we choose glass with proven longevity and plan the came, reinforcement bars, and weatherproofing to match. For panels that will live in historic or civic settings, we align our approach with recognized stained glass preservation standards set by the Stained Glass Association of America, so the new work can stand alongside — or eventually be maintained alongside — older windows without conflict.

This is also where the design’s character takes physical form. The same cartoon can become two very different panels depending on whether we lean into jewel-toned antique glass for a chapel or cooler beveled textures for a contemporary commercial interior. Every choice is deliberate, and every choice is tied back to the original intent we captured in consultation.

Fabrication: Where the Sketch Becomes Structure

In the studio, the approved cartoon becomes the template for cutting, leading, and soldering. Each piece is cut to the cartoon’s lines, then fitted into lead came that does double duty — holding the glass and carrying the design’s rhythm. Rebar and structural bars are integrated where the panel’s size or orientation demands them, which is especially important for the larger openings common in churches and civic buildings across San Antonio and the surrounding Hill Country.

Throughout fabrication we keep the installation conditions in mind. A panel destined for a humid sanctuary near New Braunfels is built and sealed differently than one going into a climate-controlled downtown office, and those decisions are locked in during this stage — not improvised at the job site. This attention to the build environment is what allows custom stained glass in San Antonio to hold its integrity through the long, humid summers that define the region.

Installation: the Final, Careful Step

Installation is where months of planning either hold together or fall apart, so we treat it as its own discipline. We coordinate framing, weatherproofing, and protective glazing as needed, and verify the panel sits true before we consider the work finished. For clients who already have older windows in place, a new commission can also be planned alongside a careful restoration of existing San Antonio stained glass, so new and historic pieces age as one coherent collection rather than competing with each other.

By the time the last came is puttied and the frame sealed, the concept sketch that started it all is no longer a sketch — it is light moving through a finished panel, as the client and we envisioned. That is the payoff of a process-led approach to custom stained glass in San Antonio: the final result is never an accident.

Ready to Begin Your Custom Stained Glass Project in San Antonio?

Custom stained glass in San Antonio deserves a process built for this city’s light, history, and climate — not a one-size-fits-all template. At Commercial Art Glass, we walk every client from the first concept sketch through to a careful, climate-aware installation, and we would welcome the chance to do the same for your space, whether it is a sanctuary, a commercial interior, or a private home. If you are considering new work, or want a panel designed to complement what we already build for San Antonio clients, reach out to us to schedule a consultation. We will bring the sketchbook — you bring the wall of light you want to transform.
