Conservation materials

Period properties were originally built from the inside out using breathable materials, so the whole structure was designed to be naturally permeable.

Many modern building materials are totally impermeable to water ingress but using these types of material and modern techniques during repair of a period property can lead to further problems in the long run. For example, re-pointing with a modern sand/cement mix may lead to long-term damage as the mortar is impermeable and will force water to evaporate from the masonry which can lead to a build-up of harmful soluble salts. At Dunne and Co we advocate the use of traditional conservation materials to prevent long-term damage and retain the historical integrity of the building.

Over the years we have developed strong relationships with our suppliers, so we’re able to closely match materials to the original. Bricks, roof tiles and oak are often reclaimed and we also retain our own stock of materials from demolitions.  Stone and flints are cleaned and re-used where possible. Locally sourced sand and aggregate help to match the existing, or surrounding buildings. Breathable materials such as hydrated  lime mixes, hydraulic lime mixes and lime putty are used as appropriate and we carefully match the colour and texture to the original property. Sheepswool  and eco-boards are our preferred insulation materials. There is also an excellent range of conservation breathable paints and lime washes available, so there is no need to compromise on aesthetics when it comes to decorations.
