Conservation plasterwork

Heritage plastering that respects the hands that came before.

Conservation-grade plasterwork for listed and historic buildings — repairing and reinstating original finishes with the same materials and methods they were made with.

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.

Common questions

Questions we hear most.

What is the difference between a heritage plasterer and a general plasterer?

Materials and intent. A general plasterer works mainly in gypsum and cement, aiming for flat, fast, modern finishes. A heritage plasterer works in lime and earth, matches what is already on the wall, and aims to conserve original fabric rather than replace it. On pre-1930 solid-wall and listed buildings the wrong choice causes real damage.

Do I need listed building consent for replastering?

Often, yes. Replastering that affects the character of a listed interior — removing historic plaster, changing finishes — generally needs consent, while genuine like-for-like repair is usually acceptable. The judgement sits with your local conservation officer, and we can help you scope and document the work so the application is straightforward.

Can old plaster with cracks or bulges be saved?

Frequently. Cracked and even partially detached historic plaster can often be consolidated, re-adhered or grouted back to its background rather than pulled down. Original lime plaster is part of a building's historic fabric — saving it is usually better conservation and often less disruptive than replacement.

How much does heritage plastering cost?

It depends entirely on the building: the condition of the existing plaster, how much can be conserved, access, and the finishes required. We inspect first and quote from a clear written scope, so you know exactly what is included before any work starts.
