RM Builders & Contractors provide expert material conservation in Devon, Cornwall and surrounding counties with a strong focus on protecting the original fabric of historic and listed buildings. Conserving traditional materials is essential to maintaining a building’s character, authenticity and long-term performance. For this reason, we prioritise repair over replacement wherever possible, so each structure continues to reflect its original craftsmanship.

Our approach to material conservation is based on a clear understanding of traditional materials such as stone, brick, lime mortar, timber and historic metals. These materials behave differently from modern alternatives, especially when exposed to moisture, temperature changes and movement. As a result, we can identify early signs of damage and apply suitable repair methods that work with the building rather than against it.

Material conservation work often includes careful cleaning, repair and protection of existing elements. For example, we repoint masonry using compatible lime mortars, repair timber sections and stabilise stonework. We also address corrosion in historic metal features. In addition, all work is carried out using materials that match the original construction, which helps prevent long-term damage.
