Stained Glass Restoration in Fort Collins: How We Bring Historic Panels Back to Life

Fort Collins wears its history well. Walk through Old Town on a quiet morning and you’ll pass Victorian-era storefronts, late-19th-century churches, and homes in neighborhoods like the Loomis Addition whose original architectural details — including original stained glass windows — have survived more than a century of Colorado seasons. At Fort Collins Stained Glass, stained glass restoration is one of the most meaningful things we do. When a historic panel comes through our studio, we understand that we’re holding someone’s family history, a congregation’s heritage, or a craftsperson’s century-old handiwork in our hands. We take that seriously.

Why Stained Glass Restoration Matters in Fort Collins

Properly maintained leaded glass can last 80 to 150 years — sometimes longer. The challenge is that most stained glass panels don’t receive the regular inspection and care they need. Lead came, the metal strips that hold individual glass pieces together, oxidizes over time. The cement or putty behind the came dries out and loses its grip. Panels begin to bow outward under their own weight, joints crack, and glass pieces shift or break. In Colorado, where temperature swings between cold mountain winters and warm Front Range summers add thermal stress to already aging materials, deterioration can accelerate.

Fort Collins’ robust Historic Preservation program recognizes how much these details matter to the character of the city. Many homeowners and congregations here are committed to maintaining the authenticity of their properties — and that commitment often leads them to us when their stained glass begins showing its age.

Signs Your Stained Glass Panel Needs Professional Restoration

Stained glass issues rarely announce themselves all at once. More often, they develop gradually over years. Here are the warning signs we most commonly see in Fort Collins homes and churches:

• Bowing or bulging. If a panel is visibly sagging or pushing outward, the lead structure has weakened and the panel is at risk of collapse if not addressed.
• Cracked or missing glass. Individual pieces crack from thermal stress, accidental impact, or shifting in a deteriorating came matrix.
• Brittle or oxidized lead came. Lead that has turned white-gray, is flaking, or crumbles when touched has reached the end of its functional life.
• Failing cement or putty. Dried-out cement rattles when you tap the panel and allows water and drafts to enter.
• Water infiltration. Staining on surrounding woodwork, damp smells near window frames, or frost buildup in winter often trace back to compromised stained glass joints.
• Visible gaps at solder joints. When solder connections between lead lines open up, the structural integrity of the whole panel is at risk.

If you’re seeing one or more of these issues, the sooner you bring in a professional, the better. Panels that are addressed early are far easier — and less involved — to restore than those that have been left until structural failure is imminent.

Our Restoration Process

When a panel arrives at our studio, or when we visit a site to assess a window in place, we begin with a thorough documentation and assessment phase. We photograph the panel in detail, note the condition of each came line, identify cracked or replaced glass, and assess the structural support system. This documentation isn’t just for our records — it guides every decision we make during the restoration and gives the owner a clear picture of what we found and what we did.

For panels that need re-leading — the most complete form of stained glass restoration — we carefully disassemble the window, removing each glass piece and cataloging it by position. We clean the glass, repair or replace broken pieces using matching art glass, and then rebuild the panel from scratch using new lead came sized and profiled to match the original as closely as possible. Every joint is soldered, the came is cemented, and the panel is cleaned and polished before it goes back in its frame.

For panels with isolated damage — a single cracked piece, a handful of failing solder joints, or a small area of deteriorated came — we can often perform targeted repairs without full disassembly. This approach preserves as much of the original material as possible, which is particularly important for historic or antique panels.

Our work follows the standards published by the Stained Glass Association of America, which provide detailed guidance on preservation philosophy, documentation, lead came replacement, protective glazing, and cleaning. These standards exist because the field has learned hard lessons about well-intentioned but poorly executed restoration work — and we apply them on every project.

Protecting the Restored Panel

A freshly restored stained glass panel is an investment, and protective measures can dramatically extend its life. In many applications — particularly exterior-facing windows in Fort Collins churches and historic homes — we recommend a protective exterior glazing system. A clear, vented exterior panel installed a few inches in front of the stained glass shields it from direct weather, UV degradation, and accidental impact while still allowing the window to be viewed and enjoyed from both sides. The airspace between the panels also improves energy efficiency, which matters during Northern Colorado winters.

We walk every client through the protective glazing options available for their specific window type and help them understand the long-term maintenance requirements so that their restored panel stays in great shape for generations.

Restoration for Homes, Churches, and Historic Buildings

Our restoration work spans a wide range of projects. In residential settings, we frequently work on leaded glass cabinet doors, transom panels, and decorative art glass windows in craftsman bungalows and Victorian homes throughout Fort Collins and the surrounding communities of Loveland, Windsor, and Timnath. In religious settings, we handle everything from small sanctuary accent windows to large narrative panels that have anchored worship spaces for a hundred years or more. Each project comes with its own history, and we approach that history with the respect it deserves.
