Identify what matters
Original plasterwork, timber profiles and historic decorative finishes can be obscured by repeated coating or damaged by unsuitable preparation. Record the features to retain and obtain appropriate advice before stripping or altering them.
Check the proposed work
Historic England advises owners of listed buildings and homes in conservation areas to seek advice before changes, as consent may be required. Discuss the particular proposal with the relevant adviser or local authority. Do not assume a generic rule covers every internal or external surface.
Agree a compatible approach
The existing materials and condition should inform the specification. A product described as heritage is not, by that label alone, a complete answer. Define the extent of repairs, any samples and the limits of preparation before work starts.
For listed buildings and conservation areas, check the proposed work before starting. See Historic England’s advice on redecoration.
