Frequently Asked Questions

Most custom stained glass commissions take 3 to 6 weeks from design approval to installation. The timeline depends on the complexity of the leaded glass design, the number of glass pieces, and any specialty glass sourcing required. Sunday Projects handles everything from stained glass design through to on-site installation across Toronto.

Every custom stained glass window starts with a full-scale design, drawn to the exact dimensions of your opening. Once the stained glass design is approved, each piece of glass is hand-selected, scored, and cut to shape. The pieces are then assembled using lead, soldered at each joint, and sealed with putty for weatherproofing and structural integrity. All stained glass windows by Sunday Projects are handcrafted in Toronto.

Sunday Projects designs custom stained glass windows in a wide range of styles including Victorian, Edwardian, Art Deco, Mid-Century Modern, and contemporary geometric patterns. Every stained glass piece is custom designed to suit your Toronto home’s architecture and your personal taste — from front door windows and transoms to bay windows and interior accents.

Absolutely. Many stained glass clients come with photos, sketches, or references from Pinterest, magazines, or other leaded windows they admire. I use these as a starting point and work together with you through the stained glass design process to refine the concept until it’s exactly what you envision for your Toronto home.

Yes. Sunday Projects handles the full stained glass process from design through to on-site installation across Toronto. Your finished stained glass or leaded glass window is carefully installed and trimmed for a clean, polished look. Installation is included as part of the custom stained glass commission process.

Yes. Most antique and heritage stained glass windows can be fully restored by a professional stained glass artist. Common stained glass repairs include replacing cracked glass pieces, re-leading deteriorated lead, reinforcing sagging panels, and resizing leaded windows to fit new openings. Sunday Projects specializes in stained glass restoration for homes across Toronto.

Signs your stained glass or leaded glass window may need restoration include visible cracks in the glass, bowing or sagging panels, loose or crumbling lead, rattling when touched, drafts coming through the window, or white powdery residue on the lead lines. If your stained glass window is over 80–100 years old, it’s likely due for at least a professional assessment. Sunday Projects offers free stained glass evaluations across Toronto.

In most cases, yes. The stained glass panel is carefully removed from the frame for restoration work and then reinstalled once the lead and glass repairs are complete. If the frame itself is in poor condition, Sunday Projects can refurbish or replace it as part of the stained glass restoration project.

The individual pieces of glass in a stained glass or leaded glass window are held together by H-shaped strips of lead. The glass sits in the channels on either side of the lead, and each joint is soldered to create a strong, weathertight stained glass panel. Over time, lead can deteriorate and need replacement — this is one of the most common stained glass restoration services Sunday Projects provides in Toronto.

Stained glass encapsulation involves sealing your existing stained glass or leaded glass window within a modern thermal glass unit. This improves insulation, protects the stained glass against weather damage, and increases home security — all while preserving the original character of your heritage stained glass windows. Sunday Projects offers professional stained glass encapsulation for Toronto homeowners.

Yes. Through stained glass encapsulation, your leaded glass window is sealed between two panes of modern glass, creating an insulated unit that significantly reduces drafts and heat loss. This allows Toronto homeowners to enjoy the beauty of heritage stained glass without sacrificing energy efficiency. Encapsulation is especially popular for stained glass windows in older Toronto neighborhoods.

Stained glass windows are relatively low maintenance. Avoid using harsh chemical cleaners — a soft cloth with mild soapy water is sufficient for routine stained glass cleaning. Inspect the lead lines periodically for signs of deterioration. Sunday Projects also offers professional on-site stained glass cleaning services across Toronto for a deeper clean without the need to remove the leaded window.

With proper care, a well-built stained glass window can last 75 to 100+ years. Many of the stained glass windows I restore in Toronto are over a century old. The key factors in stained glass longevity are the quality of the lead work, proper installation, and protection from the elements — which is why stained glass encapsulation is such a valuable investment for Toronto homes.
