Timeless Beauty — Stained Glass Installers London

Stained glass adds a unique and timeless beauty to any space, casting vibrant colours and intricate patterns that captivate the eye. Whether you're looking to restore historical pieces, create bespoke designs, or require expert repairs — we are the premier stained glass installers in London.

The centrepiece at Number 21a is a bespoke stained glass transom window, handcrafted in our London workshop and installed above a smart, dark-toned heritage door. Using rich shades of amber and emerald, we integrated the house number '21a' directly into the artwork.

Conservation Area Expertise: Because the original glass remains visible and untouched, encapsulation is a preferred choice for conservation area compliance in London boroughs such as Camden, Westminster, and Kensington.

Our stained glass services include:

🎨 Bespoke design — Victorian, Edwardian, and contemporary motifs
🎨 Leadlight restoration — expert repair of damaged leadwork
✨ Stained glass encapsulation inside double-glazed units
✨ Hand-painted glass using kiln-fired methods
✅ Heritage tiling and pattern matching
✅ Conservation area and Listed Building compliant
✅ Eliminates draughts whilst preserving original glass
And much more!

Project Focus: The ’21a’ Bespoke Transom

A bespoke stained glass transom window, handcrafted in our London workshop and installed above a smart, dark-toned heritage door — using rich shades of amber and emerald with the house number integrated directly into the artwork.

🎨 Hand-Painted Glass

Every pane is individually hand-painted by our artisan glaziers using traditional techniques, creating depth and richness that machine-produced glass simply cannot replicate.

🔥 Kiln-Fired Methods

Colours are kiln-fired into the glass for permanence — they will not fade, peel, or deteriorate over time, ensuring your stained glass remains vibrant for generations.

🏛️ Heritage Design Matching

We study the architectural details of your property and match moulding profiles, tiling patterns, and period motifs exactly — creating stained glass that belongs to the building.

✨ Stained Glass Encapsulation

We carefully restore your original leaded panels in our London workshop and seal the heritage glass inside a new, thermally efficient double-glazed unit — retaining 19th-century character with 21st-century insulation.

Elegant Works — Geometric Panel Above Door

The exquisite stained glass panel situated above the door features a captivating geometric design with rich reds, blues, greens, and yellows, all centred around an eye-catching circular motif.

The way light filters through these colourful panes creates a truly unique and welcoming atmosphere in the hallway — a beautiful heritage detail integrated seamlessly with the new door installation.
Bespoke Design Service: We work closely with you from the initial sketch through to final installation, ensuring every design is unique to your property and its character.
Restoration Service: Expert restoration of damaged leadwork and broken panes, preserving historical integrity. We source period-correct glass to ensure an invisible repair.
Modern Integration: Seamlessly encapsulating original stained glass within new energy-efficient double-glazed units — the best of both worlds for period London homes.

Stained Glass FAQ

Can I keep my original stained glass if I upgrade to double glazing?

Yes. We specialise in stained glass encapsulation. We carefully restore your original leaded panels in our London workshop and seal the heritage glass inside a new, thermally efficient double-glazed unit.

What are the benefits of encapsulating leadlights?

Encapsulation allows you to retain 19th-century architectural character while gaining 21st-century insulation. It eliminates draughts, reduces external noise pollution, and protects delicate stained glass from weather damage.

Is stained glass encapsulation safe for conservation areas?

Yes. Because the original glass remains visible and untouched, encapsulation is a preferred choice for conservation area compliance across London boroughs including Camden, Westminster, and Kensington.

Can you create a completely new stained glass design?

Absolutely. We offer a full bespoke design service — from initial sketches and colour sampling through to kiln-fired production and installation. Every design is unique to your property.

How much does stained glass work cost?

Cost depends on the size, complexity of design, and whether it's restoration, encapsulation, or a new bespoke commission. Send us photos for a free assessment and no-obligation quote.
