We are able to design and produce suggested replacement mortars based on the results of analysis or from a provided sample. Often this may be on a ‘like-for-like’ basis but may be in response to failure of existing material. We can provide variations to form an exemplar panel for architects. The materials are sourced from our stocked and manufactured traditional materials: lime, sand, aggregates, additives and pozzolans.

Accurate mortar matching is essential to the successful repair and conservation of historic masonry. At Rose of Jericho, we provide a comprehensive mortar matching service that combines laboratory analysis with practical expertise in traditional materials to replicate existing mortars with precision.

Our process begins with detailed sampling and analysis of the original mortar. This may include visual assessment, microscopic examination, and where required, techniques such as acid digestion and X-ray diffraction (XRD) to identify binder types, aggregate composition, and particle size distribution. From this, we determine the proportions, grading, and material characteristics that define the mortar’s performance and appearance.

We then recreate bespoke mortar mixes using appropriate lime binders and carefully selected aggregates, matched not only in colour and texture but also in strength, permeability, and workability. This ensures compatibility with the historic fabric—allowing the building to breathe, move, and perform as intended, while avoiding the risks associated with overly hard or impermeable modern mortars.

Our mortar matching service is particularly valuable for listed buildings, conservation projects, and high-quality repairs, where visual continuity and material compatibility are critical. Whether for pointing, rendering, or structural repair, Rose of Jericho delivers mortars that are both technically appropriate and visually indistinguishable from the original.

By combining scientific analysis with a deep understanding of traditional craft, we ensure that repairs sit seamlessly within the historic fabric—preserving both the integrity and character of the building.
