St Stephen's Church, Bristol (2015)

St Stephen’s Church is located just off the city centre in Bristol and is an important church both to the local community and within the historical context of Bristol.  The churchyard walls and exterior of the café had become heavily soiled with both carbon and biological deposits.  The PCC commissioned a sensitive cleaning programme to both these elements in order to lift the exterior of the church and make the church more welcoming to the local community.  The cleaning was carried out using both the ThermaTech steam system combined  with ammonium carbonate poultices.
