We keep stocks of most mortars, plasters, lime putties, aggregates, stonedusts, laths and pozzolans on the shelf and they can normally be collected the same day. Occasionally we may need a few days to dry stonedusts. Special mixes normally have a lead time of around 5 days. All of our paints are hand crafted to order by our skilled colourmen and the lead time is normally 2-3 days. The lead time for analysis reporting is normally around 4 weeks from receipt of samples.

All of our colours are available in all of our paint types as sample pots. This allows paints to be trialled for aesthetic and functional performance of the specific paint type. A5 swatches of all colours are also available. To order visit the paint colours pages.

Traditional materials such as lime-based mortars, plasters, limewash, and distemper are vapour permeable and relatively flexible. They allow moisture to migrate through the fabric of a building, supporting natural drying cycles. By contrast, many modern cement-based mortars and synthetic paints are relatively impermeable, which can trap moisture and accelerate decay in solid-walled historic construction.

Historic buildings were typically constructed using permeable and porous materials designed to manage moisture through evaporation rather than exclusion. Maintaining permeability allows moisture to dissipate safely, reducing the risk of damp, salt crystallisation, frost damage, and timber decay. Introducing impermeable materials can disrupt this balance and lead to long-term deterioration.

For most buildings constructed before the early 20th century, lime or earth mortar was the original material. In these cases, repairs should generally be undertaken using compatible lime-based mortars to ensure appropriate permeability, flexibility, and long-term performance. Mortar analysis of existing mortar can inform what materials may be appropriate for use in repairs. For example early cavity wall construction, originally built using lime/cement mortars and metal wall ties may need careful consideration of the repair mortar.

Limewash is a traditional mineral coating composed of lime and natural pigments. It forms a permeable finish that bonds with the substrate and develops a characteristic soft, matt appearance with subtle variation. Modern paints typically form a surface film, often with lower permeability, which can alter both the appearance and performance of traditional walls.

Yes. We provide specialist mortar and paint matching services using laboratory analysis and practical expertise. This ensures that new materials replicate the composition, grading, colour, and performance characteristics of the original fabric.

Yes. We undertake site visits to assess condition, diagnose defects, and provide technically robust advice on materials and repair strategies. Our consultancy can be supported by analytical services and detailed specifications where required.

We deliver practical training in the use of traditional materials, including lime mortars, plasters, limewash, and distemper. Training can be provided at our premises or on-site, and is available on a one-to-one basis or for groups.

Yes. We manufacture and supply pre-mixed lime mortars, plasters, and paints, alongside bespoke mixes tailored to specific project requirements and performance criteria.

We regularly collaborate with architects, interior designers, and conservation professionals, providing specification advice, colour consultancy, and material guidance to support technically appropriate and visually coherent outcomes.

Yes. Our work is focused on historic and listed buildings. We provide evidence-based advice aligned with conservation best practice, supporting informed decision-making and, where necessary, listed building consent applications. The material we manufacture are appropriate for use on historic buildings.

Yes. Many of our services are tailored to individual projects. From mortar composition to colour schemes, we develop solutions based on detailed analysis, material understanding, and the specific requirements of each building.
