Even the best soundboards made from the best materials only produce optimal tone for a limited period of time (40 – 60 years) because of the huge stresses put onto the wood. When the sound board loses its elasticity, the tone quality is lowered and the piano cannot produce its full range of tone. Sluggish or unresponsive keys, loose tuning pins or brittle strings, however, are not the only reasons to have a piano restored. Pianos made by companies such as Mason & Hamlin or Steinway and Sons hold their values well. Complete remanufacturing, can restore an old vintage piano to an equivalent new piano. In addition to costing less, the woodworking, carving, re-veneering and refinishing polishing utilized on many high end pianos can also be used to repair or restore antique furniture.
