Traditional plasterwork

Services

 

Hirst Conservation undertakes all aspects of both internal plasterwork and external render and stuccowork. As well as providing conservation and restoration expertise on existing plasterwork, our plaster specialists can undertake new plastering projects using traditional materials and techniques. Work ranges from the stabilization of highly intricate moulded or cast decorative ceilings to extensive rendering projects.  We also undertake detailed condition surveys of ceilings, assessing the condition from both the underside and upper side. Where access is poor, fibre optic investigation is utilised.  Where a ceiling is found to be unstable we undertake different methods of ceiling suspension, aiming to allow future inspection of the historic plaster surfaces. Our methods aim for lightweight systems and suspension from the upper-side only, where possible.


The services offered include:

  • Initial survey work to determine the extent of conservation and the type of repairs required;
  • Analysis of existing material to ensure compatibility of repair mortars and plasters;
  • Lime plastering onto masonry, reed and lath;
  • Running/ replication of plaster mouldings in situ;
  • Fibrous plasterwork and mould making and casting of decorative elements;
  • Ceiling suspension and securing, using both traditional methods and more modern materials;
  • Consultation on major conservation and restoration projects.
