Condition and Technical Reports

We provide Condition Reports prior to restoration and Technical Reports post-restoration. These are vital documents for archives, private collectors, auction houses, galleries, museums, art dealers and insurance companies.

The Condition Report allows ACI to identify the problems to resolve and to provide our clients with a budget and timeline.

It brings together historical research, scientific information on the origins of the work, its condition and previous restorations. It may also contain maintenance recommendations.

Easel Paint-Canvas and Wood

Whether the painting is on canvas or wood our interventions can range from tear mending, to varnish removal, consolidation, filling, lining, and correcting previous restorations. Retouching brings back to life the original work without ‘reinterpreting’ what the artist had in mind.

Our restoration strategy is underpinned by the same code of ethics used by the most prestigious art institutions in the world.

Whereas old restoration techniques were employed to make the work look ‘pristine’, the techniques employed at ACI are minimalist, reversible and using only appropriate materials. In addition, all our restoration work at ACI is carefully documented. All ACI’s restoration endeavors are driven by a profound respect for artists and their work. The collective experience of the restorers at ACI means we are familiar with all types of paints from tempera, to oil, acrylics and mixed paints.

Murals and Frescos

Murals and frescos pose unique problems due to differing levels of humidity, temperature, subsidence and salinity that arise from the structural condition of a building and the climatic conditions. ACI has worked on many large scale projects covering the renaissance, neo-classical and contemporary works in churches, stately homes, chateaux, palaces and other public spaces in France and abroad.

Wood Painted Sculptures

Paint applied on 3 dimensional surfaces is exposed and therefore more at risk of being damaged, chipped or worse. Equally the wood itself can be exposed to outside factors such as insects in the form of wood borers.


Restoration techniques whether applied to stucco, stone ,plaster or mouldings are broadly similar. The principle variant is the climatic environment. An indoor decorative sculpture is less exposed to the elements though subject to the structural realities of a building and internal environment. An exterior sculpture can be exposed to rain, high temperature variations, biodeterioration, and acts of vandalism. Our job at ACI is to analyse and understand each factor before elaborating a restoration strategy.

Outdoor Bronze Sculpture

Before any conservation work can be undertaken a thorough assessment of the work needs to be undertaken in situ. This includes an analysis of the local environment as what works in one location may be innapropriate in another. This touches on issues such as levels of acid rain, the local flora and fauna, ultraviolet light and proximity to the sea. Depending on the restoration objective ACI will clean and remove incrustation using the appropiate technique. For protective coating, materials are applied for their durability, adhesion, ease of maintenance and surface appearance.

These bronze statues sometimes contain important historical artefacts. We invite you to take a look at the discovery and recuperation of 4 boxes found in the statue of Henri IV on the Pont Neuf in Paris in our video section.
