There’s a particular satisfaction that comes from returning to a site where your hands have already shaped part of the story. Working again in Blairgowrie, on a smaller satellite building connected to the same estate as the main house you restored previously, feels less like starting a new job and more like continuing a conversation with the fabric of the place.

The stone, the mortar, the scars of weather and time, they all speak in the same dialect as the big house, and because you’ve worked there before, you recognise the subtleties instantly.

The stone has that familiar warmth, the same granular texture that responds beautifully to careful cleaning and sympathetic repointing. The old lime mortar, though weathered and failing, still carries the imprint of the original craftsperson’s hand, and you can trace the continuity of technique across the estate as if the builders had left a quiet signature for anyone who knows how to read it.

The new project is a reminder of how interconnected these estate buildings once were. Even when they sit apart physically, they share a lineage. The same quarry sources, the same construction logic, the same rhythm of coursing and bonding. When you step onto a site like this, you’re not just repairing a wall, you’re stepping into a historical ecosystem.

The rubble stonework, with its irregular but purposeful arrangement, tells you immediately that this was a working building, built with practicality in mind but still shaped by the craftsmanship of its time.

The lime mortar joints, though eroded, show the same breathable, flexible qualities that have kept Scottish stone buildings alive for centuries. As you begin the process of raking out, assessing, and preparing for new lime work, you’re not imposing something modern onto an old structure, you’re reintroducing the material that the building has always known. Fantastic!

There’s a friendliness to lime that modern materials simply don’t have. It moves with the seasons, it breathes with the stone, and it ages in a way that feels natural rather than forced. When you’re working on a building with this much history, you’re not just thinking about the immediate repair, you’re thinking about how the mortar will behave in ten years, twenty years, fifty years! You’re thinking about frost cycles, moisture pathways, and the subtle ways that Scottish weather tests every joint and surface. You’re thinking about the building’s ability to shed water, to dry out, to remain structurally honest. And because you’ve already worked on the main house, you have a deeper understanding of how this particular estate responds to those pressures. You’ve seen how the stone behaves after restoration, how the lime settles and cures, how the building breathes once the project reaches completion. That experience becomes part of your toolkit, just as essential as your trowels and brushes.

Working on heritage buildings also brings a sense of stewardship that’s hard to describe to anyone who hasn’t felt it. You’re not just fixing something that’s broken, you’re preserving a piece of local identity. Blairgowrie has a long architectural memory, and every building in the village contributes to that. Especially when this building is part of the nucleus of the village. When you repair a wall or repoint a façade, you’re helping to ensure that the next generation will still recognise the character of the place. You’re keeping the continuity of craft alive, not in a museum sense, but in a living, breathing way. The building will continue to be used, weathered, and appreciated, and your work becomes part of its ongoing life rather.

There’s also a personal satisfaction in knowing that clients trust you enough to bring you back or that new clients trust you enought to have you around.. Returning to a site you’ve already worked on is one of the strongest compliments a stonemason can receive. It means the previous work didn’t just meet expectations, it became part of the building in a way that felt right to the owners and neighbours. It means they saw the care, the precision, and the respect you brought to the place, and they want that same approach applied. That trust creates a sense of partnership, not just between you and the client, but between you and the building itself and your enthusiasm and confidence in working. You’re not an outsider arriving to impose a solution; you’re someone who already understands the story and is now helping to write the next chapter.

As the new project progresses, each stage reinforces the importance of doing things properly. Cleaning back the joints reveals the true condition of the stone, and you can see where time has been kind and where it has been less forgiving. Some stones need only gentle attention; others require more substantial repair. But every decision is made with the same guiding principle: respect the original fabric. Use materials that are compatible, techniques that are proven, and judgement that comes from experience. Heritage work is never rushed, because the building itself sets the pace. Lime needs time to cure, stone needs time to settle, and the weather needs to be watched with the same attentiveness as the work itself.

By the time the project is complete, the building will look refreshed but not altered, strengthened but not modernised. The new lime mortar will blend with the old in a way that feels natural, gradually mellowing as it carbonates and takes on the patina of the environment. The stone will be able to breathe again, free from the suffocating effects of incorrect repairsand dilapidence. And the area as a whole will feel more cohesive, with the satellite building once again reflecting the same craftsmanship and material honesty as the main house.

In the end, what makes this project special isn’t just the technical work, though that is always at the heart of what you do. It’s the continuity. The sense of returning to a place where your previous work has already become part of the landscape. The satisfaction of knowing that you’re contributing to the long-term health of a historic environment. And the quiet pride that comes from practising a craft that connects the past to the present in a way few other professions can. And you're the sole witness of these small and quiet adventures.

The recreation of an historic lime mortar begins with the choice of binder, and in this case the decision to use granulated quicklime is central to achieving both authenticity and performance. Granulated quicklime allows the mortar to be produced as a true hot‑mix, replicating the thermal behaviour, expansion, and crystal development that characterised traditional mortars. Powdered quicklime does not achieve the desired effect in so great a way as granulated lime, or even lump lime.

When granulated quicklime slakes within the aggregate rather than in isolation, it forms larger, more interlocking crystals and develops a stronger mechanical key with the surrounding aggregate. This behaviour is essential in mortar mixing when the mortar must remain flexible, breathable, and capable of accommodating normal movement without cracking and most importantly, be produced the same was as the original example. The use of granulated quicklime therefore ensures that the recreated mortar aligns closely with the original material logic of the building.

The primary aggregate in the mix is a sharp sand sourced from a vein only two miles from the site. This local provenance is not merely a matter of convenience, it reflects the historic reality that builders traditionaly used sands drawn from the immediate landscape. Such sands carry the mineral signature of the local geology and therefore produce mortars that are visually and mechanically compatible with the local masonry they belong to or the mortars that have been used in the past. Sharp sand provides the coarse skeleton of the mortar, contributing strength, permeability, and resistance to erosion. Its angular grains interlock effectively, supporting the lime binder while maintaining the open pore structure required for moisture movement. Using a sand vein so close to the building ensures that the mortar will harmonise with the existing fabric in both appearance and behaviour given that it is likely the same source or related in some way.

To further enhance compatibility, a portion of the aggregate is replaced with recovered building mortar that has been carefully graded to match the sharp sand. This recovered material contains remnants of the original lime binder, historic sand grains, and trace amounts of stone dust from the wall itself. Incorporating it into the new mix reintroduces the building’s own mineral composition, improving colour continuity and promotes that the new mortar should share the same vapour permeability and flexibility as the old in part. The graded old mortar also contributes lime fines that act as nucleation sites during carbonation, subtly improving the cohesion and curing behaviour of the mix. This approach reflects a conservation philosophy that values continuity of material identity and respects the building’s original construction methods while giving us more of an educated implementation.

Beyond the coarse and medium fractions, the decision to include both fine kiln dried silica sand and chalk whiting introduces a level of fine‑tuning that enhances the mortar’s performance without compromising its traditional character. The addition of a small percentage of silica fines improves the grading curve by filling micro‑voids between the larger sand grains. This reduces shrinkage, increases cohesion, and produces a more predictable early set, all while remaining chemically inert and non‑hydraulic. However, to maintain authenticity and avoid over‑refinement, half of the silica fraction is substituted with reclaimed mortar that has been graded to the same fine particle size. This substitution ensures that the fines contribute not only to mechanical performance but also to colour matching and mineral continuity. As fines play a dominant role in colour matching.

A similar strategy is applied to the chalk whiting, a traditional ultra‑fine calcium carbonate additive valued for its ability to improve workability and creaminess. Yet, as with the silica, half of this fraction is replaced with ultra‑fine dust derived from the recovered building mortar. This substitution tempers the brightness of the whiting, ensuring that the mortar retains the warm, muted tones characteristic of historic limework. It also introduces additional lime fines and stone dust that contribute to the mortar’s flexibility and compatibility with the existing fabric. The combined effect of these substitutions is a mortar that benefits from the functional advantages of whiting and silica while remaining firmly rooted in the material identity of the building. Added sparingly and just enough to modify the mechanical function of the mix and implement an historic cross play of materials.

The overall strategy chosen i hope creates a mortar that is both academically defensible and practically effective. The granulated quicklime provides authentic hot‑mix behaviour; the sharp sand establishes a strong, breathable aggregate framework; the graded recovered mortar helps mineral and visual continuity; and the carefully balanced fines of silica and whiting, each partially substituted with reclaimed material, refine the mortar’s performance without compromising its identity. The result is a lime mortar that cures reliably, moves with the building, and integrates seamlessly with the historic masonry, embodying both traditional craftsmanship and informed conservation practice and hopefully provides this project with a mortar that is pleasing to work with, technically operational, and a firm handshake to the original mortar.
