Remedial Treatment to listed buildings and period properties requires special consideration, as there are legal requirements and limitations on what work can or cannot be carried out and which materials may or may not be used. English Heritage ( has strict guidelines regarding the remedial treatment of listed buildings and this is enforced by the local Listed Building Inspector or Conservation Officer. It can be a criminal offence to carry out unauthorised works to a listed building without attending to the correct consultation procedures.

When carrying out works to a listed building, the objective should be to retain as much as possible of the historic fabric and halt further decay. To preserve the authenticity and historic value of the property, intervention should be kept to a minimum when containing the problem.

When working on historic and/or listed buildings it is crucial that special considerations are made when planning works and choosing materials.

Where possible, Preservation Treatments use Dryzone Hi-Lime Renovation Plaster on Listed Properties.

This is an environmentally friendly alternative to hard cement renders which is highly effective and breathable renovation plaster.  Hi-Lime has a porous structure which allows walls to dry out by evaporation, achieving a dry decorative surface which is suitable for use on salt and damp contaminated walls.
