Church Stained Glass Restoration for Colorado Springs: Our Process for Preserving Sacred Windows

Colorado Springs carries a rich religious heritage that stretches back to the mid-1800s, when settlers arriving in the Pikes Peak region built churches that doubled as community gathering places. Many of those sanctuaries — and the newer congregations that followed them — feature stained glass windows that have watched over worship services, weddings, and funerals for decades. At Colorado Springs Stained Glass, we consider church stained glass restoration one of the most meaningful work we do, because these windows are not just decorative. They tell the story of a congregation’s faith, history, and identity.

Why Church Stained Glass Restoration Matters in Colorado Springs

Stained glass windows in churches face a combination of threats that residential windows rarely encounter. Church sanctuaries often have large, south-facing openings that funnel intense Colorado sunlight directly onto the glass for hours each day. With over 300 days of sunshine annually in the Colorado Springs area, UV exposure accelerates the breakdown of painted details, while thermal cycling — the repeated expansion and contraction from hot afternoons to cool mountain evenings — stresses lead came joints and weakens the structural matrix holding each pane in place.

Beyond the physics, there is the matter of legacy. A church stained glass window may have been donated by a founding family, installed to honor a beloved pastor, or designed to depict a parable central to the congregation’s theology. When that window begins to bow, crack, or lose its painted imagery, the loss is not just aesthetic. It is a piece of the church’s living history slipping away. That is why we approach every church stained glass restoration project in Colorado Springs with a deep respect for both the craft and the spiritual significance of the work.

Our Assessment Process

Every restoration begins with a thorough on-site assessment. We visit the church — whether it sits along the historic Tejon Street corridor in downtown Colorado Springs or in a newer sanctuary in Briargate or Fountain — and examine each window from both the interior and exterior. During this assessment, we look for several telltale signs of deterioration:

• Bulging or bowing panels where lead came has stretched under the weight of the glass
• Cracked or broken glass pieces, often caused by impact or thermal stress
• Faded or flaking painted details, particularly on figurative or lettered elements
• Loose or deteriorating cement between lead came and glass, which compromises weatherproofing
• Corroded lead joints, visible as white or dark powdery deposits around the came

We document every finding with detailed photographs and written notes, then sit down with church leadership to walk through what we have found. Transparency matters here. We want pastors, building committees, and trustees to understand exactly what is happening with their windows and what options are available before any work begins. Many congregations are surprised to learn that signs their church stained glass needs professional attention may have been developing slowly over years, not overnight.

The Restoration Work Itself

Once we have agreed on a plan, the physical restoration work follows a careful sequence. For windows that can be safely removed, we take them to our studio where controlled conditions allow for precise disassembly. We rub each panel to create a template that records the exact position of every glass piece and lead line — a critical step that ensures the restored window will look identical to the original when reinstalled.

We replace deteriorated lead came with new came of matching profile and dimensions, using materials that meet or exceed the standards set by the Stained Glass Association of America. Our work follows the SGAA Standards and Guidelines for the Preservation of Stained and Leaded Glass Windows, which represent the collective best practices of accredited professional studios across the country. Any cracked glass pieces are either edge-glued if the crack is stable and minor, or replaced with new glass that matches the original in color, texture, and thickness. Painted elements that have faded are carefully repainted and kiln-fired to match the original artistic intent.

For windows that are too large or too fragile to remove, we perform in-situ repairs — working on the window while it remains in its frame. This might involve re-cementing the lead came, replacing individual broken pieces with custom-cut inserts, or installing protective glazing on the exterior to shield the stained glass from future weather damage. Every approach is tailored to the specific window and the specific church.

Planning around Worship Services

One consideration that sets church restoration apart from residential work is scheduling. Churches are active spaces. Sunday services, Wednesday evening programs, choir rehearsals, weddings, and funerals all rely on the sanctuary being available and presentable. We work closely with church administrators to plan our work around the congregation’s calendar. Sometimes that means working in sections — restoring one window at a time so the sanctuary remains functional throughout the project. Other times it means scheduling intensive work during a low-activity period, such as a summer hiatus or a planned renovation window.

We also understand that scaffolding, tarps, and studio equipment in a sanctuary can be disruptive. We treat the church space with reverence, protecting furnishings, flooring, and altar areas from dust and debris throughout the process. Our team communicates regularly with church staff so there are no surprises.

Long-term Protection and Maintenance

Restoration is an investment in the future, and we want every church we work with to get the maximum lifespan from their restored windows. After completing a restoration, we provide detailed maintenance guidance tailored to the specific windows and the Colorado Springs climate. This includes recommendations for gentle cleaning techniques, inspection schedules, and protective glazing options that can extend the life of the stained glass by decades.

Properly maintained stained glass windows can last well over a century. We have seen windows in Colorado Springs churches that were installed in the early 1900s and, with periodic professional care, remain vibrant and structurally sound today. Our goal is to ensure that the windows we restore will continue to inspire worshipers for generations to come.
