Stained Glass Repair and Restoration in Western Wisconsin and Eastern Minnesota
Backwards Progress repairs and restores stained glass windows, leaded glass panels, doors, sidelights, transoms, and church stained glass throughout the St. Croix Valley and surrounding region.
From a single cracked piece or loose solder joint to bowed panels, deteriorated lead, and complete restoration, the work begins with a careful assessment of the glass, metalwork, frame, support, and original construction.
Stained Glass Services for Windows, Doors, Decorative Panels, and Places of Worship
Stained glass can fail in more than one way. The right scope depends on whether the concern is isolated broken glass, failing solder, fatigued lead came, a bowed panel, frame movement, weather exposure, or broader age-related deterioration.
Cracked and Broken Stained Glass
Repair may include replacing damaged pieces, matching color and texture, addressing loose joints, and stabilizing the surrounding panel.
Stained Glass Restoration
Older or broadly deteriorated panels may require documentation, removal, disassembly, cleaning, re-leading, cementing, finishing, and reinstallation.
Leaded Glass Window Repair
Service for leaded windows, beveled panels, antique entry glass, transoms, sidelights, cabinet panels, and other architectural glass.

Not sure what kind of stained glass you have? Send one photograph of the full window or panel, close-ups of the problem, rough dimensions, and the project location. Backwards Progress can use those details to begin identifying the construction and the most useful next step.
Small Stained Glass Problems Can Point to a Larger Structural Issue
A cracked piece may be the only visible problem, but it can also be the result of movement, pressure, weak lead, failed perimeter support, or a frame that no longer holds the panel correctly. Looking beyond the break helps prevent a cosmetic repair from hiding a continuing cause.
Earlier evaluation is especially important when a panel is bowing, rattling, pulling away from its frame, or showing daylight around the lead lines.
Common reasons to request an assessment
- Cracked, chipped, missing, or poorly patched glass
- Loose, split, or failed solder joints
- Bowed, bulging, sagging, or distorted panels
- Brittle, stretched, oxidized, or fatigued lead came
- Loose cement, rattling glass, or visible gaps
- Water intrusion, condensation, or frame deterioration
- Damage from impact, weather, vibration, or building movement
A Restoration Plan Should Match the Window's Condition—not a One-Size-Fits-All Scope
Localized stained glass repair focuses on a limited problem while preserving sound surrounding material. Complete stained glass restoration is more appropriate when deterioration affects much of the panel, the lead network has lost strength, or earlier repairs no longer support the glass correctly.
Depending on the panel, location, access, and damage, some work may be completed in place while other projects require careful removal and controlled workshop repair. The purpose of the assessment is to determine the least disruptive approach that still produces a stable result.
Preservation comes first. Original glass and meaningful historic material should be retained whenever practical. Documentation, careful handling, and compatible repair choices help preserve both the appearance and the record of the window.
Inspect and Document
Review glass, lead or foil, solder, reinforcement, frame, protective covering, access, dimensions, visible damage, and earlier repairs.
Define the Scope
Determine whether the panel needs localized repair, stabilization, partial rebuilding, complete re-leading, frame work, or another coordinated solution.
Protect the Original Design
Retain original material where practical and identify suitable color, texture, opacity, and construction for any necessary replacement pieces.
Repair or Rebuild
Complete the approved glass, solder, lead, copper-foil, cement, reinforcement, and perimeter work required by the condition.
Refit the Panel
Return the restored panel to a suitable frame or opening, with attention to fit, support, drainage, ventilation, and surrounding materials.
Record the Work
Keep a clear record of the panel's condition and completed work so future owners, caretakers, or restoration professionals understand what changed.
Leaded Glass Windows, Doors, Sidelights, and Transoms
Leaded glass windows often combine clear textured glass, colored accents, bevels, zinc or lead came, and surrounding woodwork that is part of the home's original character. Repair should account for the complete assembly instead of treating the broken piece as an isolated object.
Backwards Progress works with leaded glass in older homes, entry doors, sidelights, transoms, cabinet doors, interior panels, and other architectural applications. Potential work may include individual glass replacement, solder repair, perimeter repair, re-leading, cementing, reinforcement, removal, and reinstallation.
Leaded glass projects may include:
- Historic and antique leaded windows
- Beveled and textured clear-glass panels
- Entry doors, sidelights, and transoms
- Arts and Crafts or Prairie-style windows
- Cabinet, built-in, and interior decorative glass
- Loose joints, weak came, bowing, and broken pieces
Church Stained Glass Repair and Restoration
Church stained glass may carry artistic, historic, memorial, and congregational significance in addition to serving as part of the building envelope. That makes documentation, access planning, panel stability, original glass retention, and communication with church decision-makers especially important.
A church project may involve a localized broken piece, loose solder, failing lead, bowing panels, deteriorated frames, unsuitable protective coverings, or a larger phased restoration. Backwards Progress can assess the visible conditions and develop a scope that explains priorities and next steps.
Church stained glass planning may address:
- Condition assessment and photographic documentation
- Cracked, missing, or previously repaired glass
- Lead fatigue, failed joints, bowing, and panel support
- Careful removal, workshop restoration, and reinstallation
- Frames, support systems, drainage, and ventilation concerns
- Prioritized or phased work for larger window groups
Stained Glass Restoration for the Architectural Details Worth Keeping
Decorative glass can be part of a window, entryway, built-in, stair landing, interior door, or freestanding panel. The construction, movement, exposure, and surrounding frame all influence the repair plan.
Preserve the Glass That Gives the Home Its Character
Repair and restoration for stained and leaded windows, stair-landing panels, built-ins, cabinet glass, room dividers, and decorative architectural pieces.
Match the Repair to the Glass, Frame, and Building
Older glass may be irregular, textured, mouth-blown, opalescent, beveled, painted, or no longer manufactured. Matching is based on the actual visible qualities of the original piece.
Doors, Sidelights, and Transoms
Repair decorative glass while accounting for daily door movement, perimeter fit, safety, frame condition, and the appearance of the full entry.
Cabinets, Built-Ins, and Hanging Glass
Review loose foil, broken glass, damaged borders, weak hanging points, and frames before the piece is returned to use or display.
Antique Stained Glass Repair
Retain original glass where practical, document necessary changes, and avoid making a distinctive older panel look unnecessarily new.

Questions About Repair, Restoration, Leaded Glass, and Church Windows
Can a cracked piece of stained glass be repaired?
Often, yes. The appropriate repair depends on the crack, glass type, construction, location, and condition of the surrounding lead or copper foil. A damaged piece may be replaced with glass selected to match the original color, texture, opacity, and pattern as closely as practical. The panel should also be checked for the pressure or movement that contributed to the break.
What is the difference between stained glass repair and restoration?
Repair generally addresses localized damage such as one or more broken pieces, failed solder joints, or a limited weak area. Restoration is broader and may involve complete documentation, removal, disassembly, cleaning, glass repair or matching, re-leading, cementing, reinforcement, finishing, and reinstallation. The condition assessment determines the appropriate scope.
Do you repair leaded glass windows?
Yes. Backwards Progress works with leaded glass windows, entry doors, sidelights, transoms, beveled panels, decorative windows, and related architectural glass. More information is available on the leaded glass window repair and restoration page.
Do you restore church stained glass?
Yes. Church stained glass work may include assessment, documentation, localized repair, panel restoration, re-leading, removal and reinstallation planning, frame and support review, and phased restoration planning. Visit the church stained glass repair and restoration page for the dedicated service information.
Can old glass be matched?
Many older colors and textures can be matched closely, although an exact match is not always possible because historic glass varies and some products are no longer made. The original piece, surrounding glass, transmitted light, surface texture, opacity, and viewing distance all help guide the selection.
Does every bowed stained glass window need complete re-leading?
Not automatically. Bowing is a warning sign that requires evaluation of the lead network, solder joints, panel size, reinforcement, perimeter fit, frame, and earlier repairs. Limited stabilization may be appropriate in some cases, while widespread lead fatigue or distortion may justify complete re-leading.
Can stained glass be repaired onsite?
Some localized repairs may be possible onsite, but other work requires controlled removal and workshop repair. Panel condition, access, size, construction, glass value, safety, and the extent of deterioration all affect that decision.
What affects the cost of stained glass repair?
Pricing depends on panel size, access, construction, glass type, number of damaged pieces, matching difficulty, lead or foil condition, bowing, frame work, removal and reinstallation needs, protective coverings, documentation, and whether the project is a localized repair or complete restoration. Photographs and approximate dimensions help begin the estimate.
What areas does Backwards Progress serve?
Backwards Progress generally serves stained glass projects within approximately 80 miles of Amery, Wisconsin, including communities across Western Wisconsin, the St. Croix Valley, and Eastern Minnesota. Exact availability depends on the project and address.
What should I send when requesting an estimate?
