This article is devoted to the repair of panelled and molded woodwork, which was very popular in 17th-century Canada. There are instructions for removing and replacing the woodwork after insulation work and for replastering. Reproducing deteriorated moldings by means of a molding jig that highlights the profile is explained and ways of fixing new finishings are also described. A brief guide to the main types of wood moldings is illustrated with cross-sections drawings. -- AATA
