We were awarded tendered works lime repointing a Farmhouse which is part of a larger estate. Using lime-based mortar instead of modern cement mortar is important in the conservation of older buildings, especially those with rich historical or architectural significance when built with traditional materials.
Repointing is the process of renewing the exterior of the mortar joints between stones or bricks, a technique vital for preserving the integrity of the building’s structure while also allowing it to “breathe.” Lime mortar, unlike cement, is porous, allowing moisture to escape from the walls, which is particularly important in older buildings where trapping moisture can lead to decay of the building fabric. The use of lime mortar also maintains the aesthetic and historical authenticity of the structure.
Lime repointing involves several steps. Firstly, any damaged / deteriorated / cementitious mortar is carefully removed to avoid damaging the surrounding stone or brick. Then, the new lime mortar mixture—this time including hotlime (AKA Quicklime), grit sand, and water—is prepared. The consistency of the mix is critical to the final finish.
The fresh mortar is then carefully applied into the joints, using techniques that allow for the mortar to cure slowly and evenly. This helps ensure the repointed areas are structurally sound and visually consistent with the original construction. The mortar is then sheeted, protected and monitored until cured for brushing back to finish.
The repointing was to the roadside elevation and the gable. The provided specification required hotlime (AKA Quicklime) and grit sand mixed with local sand. We have extensive experience completing hotlime projects.
Only a stone lintel required reforming which had royally decayed over time along with rebuilding a section of the roadside elevation which appeared to have been affected from previous roofing work by others.
Such efforts are often made upon properties that require significant restoration or potentially tied to historical figures, ensuring that the farmhouse remains a lasting symbol of enduring prominence.
