Knapped flint

Flint split to expose its dark face and laid as the finished surface of the wall — the traditional walling of Sussex.

Hot lime mortar

The traditional mortar for flint work. We build and repair with hot lime mortar, not cement.

Repair, restoration, new build

From repointing and coping repairs to restoring a tired wall or building a new one from the footing up.

Flint in the landscape

The building stone of the Sussex Downs.

Flint walls bedded in lime are part of this landscape. They can be repaired, rebuilt and extended in the same materials they were built with.

The craft

Knapped flint, laid in hot lime mortar.

Knapping splits each flint to expose its dark, glassy face. Laid to course, with brick or stone dressings at corners and openings, it makes the walls seen throughout Sussex — and it is how we build and repair them.

Lime mortar is softer than the flint it holds and lets a wall breathe. Hot-mixed lime is the traditional mortar for this work, and it is what we use.
