What heritage plastering means
Heritage plastering is conservation work, not decoration. The aim is to keep as much original fabric as possible, repair what can be repaired, and replace only what has genuinely failed — using materials that match the original in composition, strength and behaviour. On a listed building this is usually not just good practice but a condition of consent.
That discipline changes how the work is done. Instead of hacking off and starting again, a heritage plasterer reads the existing plaster first: how many coats, what binder, what aggregate, whether it sits on stone, brick, lath or daub. Repairs are then designed to sit quietly alongside the old work — matched in texture and plane, breathable like the original, and honest enough that a future conservator can tell what was done.
Our heritage plastering service
- Conservation repair of historic lime plaster on walls and ceilings
- Haired lime plaster on riven lath — ceilings, partitions and soffits reinstated the traditional way
- Consolidation of delaminating or water-damaged historic plaster, keeping original material in place
- Run mouldings, cornices and simple ornamental work repaired or re-run in lime
- Earth and daub repairs on timber-frame buildings
- Specification support — method statements and material specifications for conservation officers and architects
Working on listed buildings
We regularly work under listed building consent and alongside conservation professionals. That means like-for-like materials, minimal intervention, reversibility where practical, and paperwork done properly: method statements before work starts, samples agreed on the wall, and changes recorded. If your conservation officer has asked for a specialist rather than a general plasterer, this is the service they mean.
Materials matched to the building
Historic plasters vary enormously — chalk-rich binders, earth plasters, hot-mixed lime, hair of different animals and lengths. Where it matters, we match new work to the original: lime putty and hot-mix repairs for soft historic backgrounds, natural hydraulic lime only where exposure genuinely demands it, and aggregates chosen to match colour and texture. The result ages with the building instead of fighting it.
Where we work
Heritage plastering across South Wales, the Marches and the West Country — Newport, Cardiff, Monmouthshire, Abergavenny, Hereford, Gloucester, Bristol and Swansea. Chapels, farmhouses, townhouses and timber-frame buildings are the bread and butter; for unusual buildings further afield, ask.
