Period & Listed Buildings
Older and listed buildings need a careful, considered approach to repointing. The materials and methods that suit a modern house are often the wrong choice for a historic one, and getting it wrong can do lasting harm.
Older bricks and stone are usually softer than modern equivalents, and they generally need a compatible, breathable mortar rather than a hard modern mix. The existing historic mortar should be looked at and understood before any decisions are made about what to replace it with.
Appearance matters on these buildings. The colour of the mortar, the aggregate and the joint finish all affect the character of the elevation, so careful mortar matching is an important part of the work rather than an afterthought.
Care during removal is just as important. Excessive or careless raking out can damage the arrises and faces of old bricks and stone, so removal needs to be done by hand where appropriate and no more than necessary.
Listed buildings can involve consent or conservation requirements depending on the nature of the work. We would always encourage you to make the appropriate checks where necessary, and we are happy to work sensitively within those requirements. We do not make legal promises about whether a particular job does or does not need consent, as that depends on the specifics.
Our Process
Understand the building
We look at the masonry, the existing mortar and the character of the building before recommending anything.
Considered specification
We recommend a compatible mortar and approach suited to the age and construction of the property.
Appropriate checks
Where relevant we encourage the appropriate checks on consent or conservation requirements.
Careful removal
Old mortar is removed by hand where appropriate, protecting the historic masonry.
Matched repointing
The building is repointed with a matched mortar, finished to suit its character.
Curing and protection
Lime work is given time and protection to cure properly.

Frequently Asked Questions
It depends on the building and the nature of the work, so we cannot give a blanket answer. We would encourage you to check with the appropriate authority where necessary, and we are happy to work within any requirements.
Older, softer masonry usually needs a softer, breathable mortar. A hard cement mix can trap moisture and push it out through the brick or stone faces, which can damage the masonry over time.
Matching is a priority on period and listed work. We consider colour, aggregate, texture and joint profile so the repointing suits the character of the building.
Yes. Over-aggressive raking out can chip and damage the edges and faces of old bricks and stone. This is why careful, appropriate removal matters so much on older buildings.
