Understand the wall
The condition of joints and surrounding masonry helps determine where repair is appropriate and what information is needed before work is specified.

Lime Mortar Repointing for Listed and Historic Buildings
Survey-led lime mortar repointing for listed and historic brick and stone buildings, with compatible materials, careful joint repair and trial-panel support.
Discuss the proposed scopeWork shaped by the existing masonry and project context.
Lime mortar repointing can change how historic masonry manages moisture and movement. A suitable approach starts with the existing construction, mortar condition, joint profile and wider project context rather than selecting a mix from a generic recipe.
Our work is planned around retention of sound fabric, compatible replacement mortar, an appropriate finish and clear delivery sequencing. The agreed scope can include localised removal, joint preparation, repointing, local brick repair and sample panels where useful to the project team.
How the work is approached
Clear decisions before work begins.
Match the repair to the material
Lime, sands and aggregates are considered in relation to the existing fabric, exposure and required appearance.
Protect adjacent fabric
Removal, preparation and application are planned to minimise avoidable disturbance to historic brick and stone.
Record the agreed outcome
Site records and practical project information are maintained in line with the defined masonry scope.

Frequently asked questions
Questions before a specialist scope is agreed.
Where Listed Building Consent or formal heritage advice is required, the relevant local planning authority and appointed advisers should confirm the route forward.
Is lime mortar always required on a listed building?
Material choice depends on the individual building and its existing construction. A listed status alone is not a material specification, so the proposed repair should be assessed in context.
Why does the joint profile matter?
Mortar joints contribute to the appearance and weathering performance of a wall. The existing profile and the desired repair outcome should therefore be considered as part of the scope.
When is a trial panel useful?
Trial panels can provide a practical way to review colour, texture and finish before wider work proceeds. They are most useful when the project team needs an agreed visual reference.
