Heritage and conservation trades A–Z dictionary
UK trade reference · plain English
Historic fabric needs an understanding of how the building was constructed and how repairs affect its drying, movement and significance. A modern material is not automatically an improvement, and an old-looking product is not automatically compatible. Permissions, investigation and proportionate intervention can be as important as the visible finish. These terms help discuss repairs with a suitable specialist, without assuming every older building needs the same treatment.
This A–Z combines useful technical vocabulary with links to full references where the article meets our depth and sourcing checks. An unlinked definition is intentionally kept here rather than turned into a shallow standalone page. Read a quotation against its actual scope: a familiar word is not a complete specification.

C
- Conservation
- Managing change to retain significance and fabric, rather than making every surface appear newly manufactured.
- Consolidation
- A treatment intended to strengthen vulnerable material in appropriate circumstances. Compatibility and the cause of deterioration require assessment.
G
- Getting into stonemasonry
- Stonemasonry shapes, fixes and repairs stone for buildings, interiors, memorials and other structures. Workshop carving, stone fixing and heritage conservation have different demands. A good entry route explains the intended specialism and develops practical skill without assuming every stone or historic repair behaves like modern masonry.
L
- Lime mortar
- A mortar using lime binder in a specified formulation. Not every lime product has the same properties or use.
- Lime pointing
- Lime pointing is the finishing or renewal of masonry joints using a lime-based mortar selected for the building. It is commonly associated with repair of traditional brick and stone construction.
- Listed building consent
- A consent process for relevant works affecting a listed building's character. It is separate from ordinary planning permission.
P
- Patina
- Surface change associated with age and use. Removing it may remove historic character rather than merely dirt.
R
- Repointing
- Renewing appropriate mortar at masonry joints. Joint preparation and mortar compatibility affect the surrounding fabric.
S
- Sacrificial repair
- A designed repair intended to weather preferentially rather than damage more significant adjacent fabric.
- Stone indent
- A suitably designed replacement stone piece inserted into existing fabric. Material and fixing require a compatible detail.
