Wood conservation is the professional care and treatment of wooden objects, including furniture, carvings, panelling and architectural elements, with the aim of stabilising them and preserving as much original material and evidence as possible. It differs from restoration in placing the emphasis on minimal intervention rather than returning an object to an ideal or as-new appearance.
Conservators begin by examining and documenting the piece, identifying the timber, construction, finishes and any later alterations. Typical treatments include consolidating weakened or insect-damaged wood, re-adhering lifting veneers with reversible animal glues, stabilising joints, cleaning dirty surfaces without removing original finishes and filling losses only where necessary for structural or visual reasons. Environmental control is central, as fluctuations in humidity and temperature cause timber to shrink, swell and crack. Woodworm and other pests must be identified and treated without damaging the surface. Conservation principles favour reversible materials so that future specialists can undo work if needed. For collectors, an understanding of conservation helps in judging the honesty of a piece, as old surfaces, original patina and untouched construction are generally worth more than heavily refinished or rebuilt examples.
