Conservation experts have successfully cleaned the medieval stonework on the entrance of a church in Wiltshire.

St Peter's Church on Marlborough High Street is a 15th century building that has been managed by a charitable Trust since 1978, and requires regular cleaning to prevent the build-up of organic matter and carbon deposits. 

The company Stonehealth, specialising in cleaning machines, offered its machines with high pressure steam to remove moss and algae, as well as a device to tackle carbon deposits, by combining low air pressure, water and a fine granulate to create a swirling vortex to delicately clean the stonework.

The Wiltshire Gazette and Herald: Brian Crowe of Stonehealth and Nicki Evans Trustee at St Peter's and Paul's Marlborough Trust

Nicki Evans, trustee and secretary at St Peter’s and Paul’s Marlborough Trust, said: “As custodians of this magnificent building we have a duty to protect its structural integrity for the benefit of future generations.”

The space also provides vital educational, musical, creative and social activities and a popular coffee shop for the community.

Brian Crowe, executive chairman and founder of Stonehealth, added: “We care deeply about the preservation of our nation’s heritage and it’s great to see this church continuing to be used as a focal point of the community in Marlborough.”
