Longhouse Cockermouth - 1800s

Longhouse is a traditional terrace property in Cockermouth, originally forming part of a larger building before being divided into smaller homes. The masonry showed signs of moisture retention associated with inappropriate modern repointing materials and changes at ground level.

Previous cement-based pointing had contributed to trapped moisture within the brickwork. In addition, a later patio installation had raised external ground levels, restricting natural moisture movement at the base of the walls. While the patio was not removed as part of this phase of works, a breathable lime mortar was selected to better support moisture movement through the joints.

Existing mortar was carefully removed using hand tools only, ensuring the surrounding brick and stone were not damaged. Once raked out, the masonry was cleaned thoroughly in preparation for repointing.

Repointing was carried out using a traditional hot lime mortar, selected to suit the strength and permeability of the original materials. Once the mortar had reached a green-hard stage, the joints were brushed back and finished using a combination of wire brushes, shaped timber tools, and finally compacted using a churn brush to consolidate the surface and achieve an appropriate traditional finish.

During carbonation, the work was protected using hessian to shield the fresh lime mortar from wind, rain, and direct sunlight. The masonry was regularly dampened to support a slow, controlled curing process and to ensure correct carbonation.

The work was carried out using traditional lime materials and methods appropriate to the age, construction, and exposure of the building, with care taken to respect its character and original masonry.
