Stone conservation is as much about judgement as it is about craft. From modest repairs to major restoration, we work carefully with historic and contemporary stone buildings to stabilise, repair and protect them for the long term.

Drawing on generations of masonry experience and modern conservation practice, we combine technical understanding, careful material selection and skilled handwork, always guided by the principles of minimum intervention and long-term care.

Care for Historic and Natural Stone

Minimum Intervention,
Maximum Integrity

Every building and stone type tells a different story. We conserve and repair limestone, sandstone, granite, marble, terracotta and travertine, working across churches, estates, civic buildings and listed properties.

Our experience includes Listed structures and projects for clients such as English Heritage, National Trust, Historic England and private estate owners.

From the choice between a mortar repair and a new indented stone, to the selection of pointing mortars and cleaning methods, every action has a long-term impact on the building.

Protecting Stone for Future Generations

Skill, Patience
and Deep Knowledge

By combining technical understanding, careful material selection and skilled handwork, we help ensure that historic stone buildings can continue to perform and weather well for future generations.

Our NVQ-qualified site masons and conservation teams carry out cleaning, stone repairs, replacements, piece repairs, repointing and associated detailing, monitoring interventions throughout.

Our Process

From Survey to Conservation

Survey, Diagnosis
and Strategy

We begin with a careful assessment of the building and its stone. This may include visual surveys, condition reports and discussions with architects or conservation officers. We identify the causes of deterioration and develop a conservation strategy that balances significance, risk, budget and access.

Trials, Specification
and Planning

Before full works proceed, we agree the right techniques and materials. This can include cleaning trials, sample mortar mixes with colour matching, and mock-ups of piece repairs. From this, we prepare detailed specifications and programmes so everyone understands the proposed approach.

Conservation Works
and Ongoing Care

Our NVQ-qualified site masons and conservation teams carry out the agreed works: cleaning, stone repairs, replacements, piece repairs, repointing and associated detailing. On completion, we advise on maintenance and inspection regimes.

Good conservation leaves no trace of itself — the building speaks for itself, cared for rather than altered.

Whether you are managing a listed property or a well-loved historic building, we bring the knowledge, care and skill to protect it for the long term.
