Picture framers make and supply frames for artwork, photographs, prints, certificates, textiles and other items. They typically offer a choice of frame styles, finishes and materials, then measure and cut components to fit the item. Services may include selecting mountboard, adding a window mount, fitting glass or acrylic glazing, and assembling a backing and hanging fixings. Some framers also provide ready-made frames, replacement glazing and advice on suitable display or storage. Picture restorers assess damaged or ageing pictures and carry out work intended to stabilise or improve their condition. Depending on the material and the extent of the damage, this may include cleaning, repairing tears or holes, retouching losses, treating mould, or repairing a canvas, stretcher or frame. Conservation framing can use methods and materials designed to reduce contact with the artwork and help protect it from dust, light and changes in humidity.
