Our Company

We principally within Wales and the South West of England but will undertake projects further afield if of suitable interest and importance.

Stonemasory Carving and Conservation

Our fitting of new stone within an old context is technically sound and ethically justified.

DOFF Cleaning

High temperature steam provides a gentle, low volume clean that doesn't saturate the surface. Removes moss, algae, fungi and will kill spores. No need for Chemical biocide.

Previous work


Repair to the shaft stonework around corroding cramps which included:

  • dismantling and rebuilding the detached shafts at clerestory level.
  • repairing and cleaning the windows.
  • redecorating the white-painted areas.
  • lightly cleaning the stonework, and rubbing-down the timber ceiling to remove previous water staining.

Glynn Vivian Art Gallery

Stone cleaning and repair to the main facade including both indent and replacement stone.  Significant repairs to the central entrance doorway. This heavily embellished pediment required careful cleaning and build up of detail using mortar repair techniques.  We used both hot mixed lime mortar and shelter coat to protect the finished work.

St Mary's Church

Significant and full depth tracery replacements in Elm Park Bath stone. The original stone had decayed to the extent that the stained glass work was in some areas holding the structure in place. A busy church in continuous use meant that we had to contain the works in sheeted scaffold inside and out and program our works around ongoing services. The completion date for these works was crucial as it was set shortly before the important wedding of two members of the clergy.

St Cadoc's Church

The significance of this already important medieval church of St Cadoc’s at Llancarfan grew massively when routine works uncovered evidence of 15th century wall paintings.

We were appointed when the survey work being carried out in the first phase raised concerns about the stability of the west window. The conservation brief involved working closely with the wall painting conservators to delivery sympathetic consolidation of the tracery. Great importance was placed on minimising vibrations and dust whilst working to tight time constraints..

Cardigan Castle

With a team of up to 14 strong over a period of nearly two years, Coe Stone undertook consolidation and repair work to both the historic castle walls and to many of the associated buildings. Much anticipated locally, the repair and reinstatement work to the curtain walls allowed the removal of the ugly steel stantions that had long blighted the town.

One of the standout achievements for us on this project was to successfully negotiate the reduction of heavy engineering in the stabilisation of the medieval tower. With the backing of both CADW and the architect we were able to argue for less intervention and therefore preserve more of the historic fabric and character of this structure.
