StoneworkOld wallsWhat we doMuch of our work is restoring existing stonework. As well as making a building look unsightly and neglected, poorly maintained stonework can result in damp finding its way through to the inside.Why is restoration needed?Buildings made of natural materials eventually show signs of ageing, such as:• sandstone breaks up and wears away • the material holding stones together gradually disintegrates and falls out • patches of old mortar and render trap water in the wall and cause the stone behind them to erode. How we restore stoneworkIt’s important that restoration of stone walls is undertaken by a professional. Done properly, it can transform the appearance of a building and will last for many years. Without the correct tools and materials, DIY solutions can make matters worse.Restoration involves:• removing old mortar and render• cutting out and replacing badly eroded stones • repointing (filling in the gaps) with a specialist lime mortar mix. It’s vital to use the correct ‘recipe’ for the mortar, in order to:• complement the colour of the stones• blend in with the rest of the structure • make the stonework strong and durable • allow the wall to ‘breathe’, preventing damaging moisture from being trapped.
