Before & After


Traditional Cornice Restoration Techniques

Cornice Running
One of our core skills is running cornices in situ — the same method used in the 18th and 19th centuries. Using a hand-crafted zinc profile on a running horse, we recreate the original moulding directly onto your walls and ceilings. This approach ensures:
- The cornice naturally follows the undulations of old buildings.
- A seamless finish without unsightly joints.
- A solid, integral part of the room rather than a facsimile.
Repairing and Replacing Sections
Where sections of cornice are cracked, missing, or damaged by building works, we carefully replace sections or run new lengths to match the original. Our process may involve:
- Casting new designs where originals have been lost.
- Raking out and filling small cracks.
- Casting and attaching new enrichments such as acanthus leaves, egg and dart, or dentils.
