Granite Le Pelley was asked by the Catholic Church of Guernsey to replace the 10 front elevation arch window tops at their Alderney Church, which had failed due to water ingress. This involved visiting Alderney to site measure each arch to see if it was possible to make all 10 arch’s the same and as single units, not as three units per arch as previously done, this would allow for a more cost effect solution on casting and installation, two mason spent 5 days removing the old arch units and replacing them with new single arch units, the replacement were cast to Granite Le Pelley's detailed drawing by Sterling Services in Shorncote /Ballidon with a medium acid etch finish.
