Cleaning, lime mortar repair and new stone matched to the original, on some of the most important buildings in Britain.
Discuss your building
Stone and brick decay unevenly: the sunny side of a chapel suffers more from heating and cooling, hard cement repairs trap water, and pollution hides carved detail.
Our approach is to limit replacement to failing stones, repair with soft lime mortars, and where new stone is needed, find the right one. At Hampton Court's Base Court the restored outer wall surface now acts as a sacrificial jacket to the Tudor core.
What a programme covers
As carried out on the external stonework of St George's Chapel, Windsor.
Finding the right stone for a problem unresolved for over 150 years
No limestone quarried in the UK matches Caen stone's colour, texture and performance. Our team researched French limestones and visited a recently re-opened Caen mine at Cintheaux in Normandy.
Rigorous independent sample testing by the British Research Establishment confirmed it was the correct stone for the replacement and repair work.
