Developing an appropriate treatment strategy requires a holistic examination of the window, its setting and historic context. We recognise the significance of all historic material, and aim to conserve both glass and leadwork where possible. Our guiding principles focus on minimally invasive treatments, making reversible interventions where necessary and justifiable, and preventive systems to mitigate future harm. Where windows show evidence of ongoing deterioration through glass corrosion, paint loss or biological growth of moulds or algae, we recommend the installation of internally ventilated Environmental Protective Glazing (EPG, previously known as ‘isothermal’ glazing). Barley Studio also create custom-made light boxes to display stained glass independent of the architectural setting.

Barley Studio adheres to the Conservation Guidelines of the international Corpus Vitrearum Medii Aevi (CVMA) and the Church Buildings Council (CBC). All conservation work is undertaken in-house by our multi-skilled team, including restoration painting by our skilled artists and glasspainters. All projects are fully documented, from initial condition to records of work undertaken. We also provide recommendations for future maintenance to assist clients in planning for the long-term care of their windows.
