Ecclesiastical

01

Churches, cathedrals, and houses of worship.

Religious stained glass represents some of the finest craftsmanship in architectural history. From rose windows to narrative lancets, we restore ecclesiastical glass with the respect and precision these sacred works demand.

Our work on church doors and steel entryways — including projects like St. Paul the Apostle Cathedral — often involves restoring stained glass panels integrated into the metalwork, combining our glazing and metalworking expertise in a single project.

Residential

02

Transoms, sidelights, and decorative panels.

Victorian homes, brownstones, and estate properties often feature stained glass transoms, sidelights, cabinet inserts, and decorative ceiling panels. These pieces are integral to a home’s character and value.

We repair cracked glass, re-lead deteriorated panels, restore painted details, and fabricate historically accurate replacement pieces when originals are beyond repair.

Commercial & Historic Landmarks

03

Courthouses, universities, and public buildings.

Large-scale stained glass projects in public and commercial buildings require careful logistics: scaffolding, phased removal, secure transport, and precise reinstallation. We manage the full scope from assessment through final installation.

Our NYS and NJ DOT-certified welders handle the steel and iron frames that house stained glass in many institutional buildings, ensuring both the glass and its supporting structure are properly restored.

What Our Clients Say

★★★★★
We used Olek Inc. to shorten and polish our beautiful heavy wood dining table. Olek had to disassemble the table, cut it, re-attach the bookends, and make it look like it was never touched. The result was flawless — you would never know it was modified.

★★★★★
I have a Vladimir Kagan 175 E armchair that was literally falling apart — the wood was separating at the joins and the leather seat and padding were shot. Peter at Olek did an amazing job bringing it back to like-new condition. Highly recommended for designer furniture restoration.

★★★★★
This is the second time I've had Olek reupholster my sofas. Each time I've been astonished at the stunning work. The craftsmanship is impeccable and the attention to detail is second to none. I wouldn't trust anyone else with my furniture.

Stained Glass Restoration FAQ.

Can cracked stained glass be repaired?

Yes. Hairline cracks can often be stabilised with edge-gluing or copper foil reinforcement. If a piece is shattered beyond repair, we fabricate a replacement matched in colour, texture, and opacity to the surrounding original glass.

How long does stained glass restoration take?

Timelines vary by scope. A single residential panel may take 2–4 weeks; a full ecclesiastical window programme can span several months. We provide a detailed timeline during the assessment phase and keep you updated throughout.

What is protective glazing?

Protective glazing is an exterior layer of clear glass or polycarbonate installed over the original stained glass. It shields against weather, vandalism, and UV damage. Vented systems allow air circulation to prevent condensation buildup.

Do you work on both leaded and copper foil stained glass?

Yes. We restore both traditional lead came (H-channel) stained glass and copper foil (Tiffany-style) pieces. Each technique requires different restoration methods, and our artisans are experienced in both.

Can painted details on stained glass be restored?

Yes. Kiln-fired painted glass can be stabilised and, where necessary, repainted and re-fired to match the original technique. We document all painted details before intervention to ensure accuracy.
