Older pipework can often be given a new life by revoicing. Age, the stress of tuning, and accumulation of dirt can cause pipes to not sound their best after many years. Cleaning and revoicing each pipe can return the original voice of the pipe, and the intended sound of the organ. This work can be done at two levels. The first is a simple tonal refinishing done in place. At the second level, all the pipes are removed and taken to the Wicks shop where every pipe is cleaned and revoiced and reed tongues are replaced. This kind of work is usually accompanied by an entire organ cleaning, which includes the cleaning of contacts and lubricating the chest action as needed.
