Periodic maintenance is of utmost importance to the flute. Many flutist does not make adjustments because they think the instrument is in good condition and tuned. Actually this maintenance is to prevent major problems in the flute. Polishing cleaning, for example, is responsible for preventing oxidation which can even cause small holes in the metal, which even a new bath will not reverse. Lubrication prevents shafts and trestles from working dry, causing wear of the metal and causing gaps between them. Removing dents prevents the air column circulating in the instrument from being interrupted by these obstacles, leaving the instrument's sound more homogeneous. The cork of the headjoint is a very important piece for the flute, if it is dry or is not making the correct seal, the flutist will feel great difficulty when emitting notes, especially in the acute region, which requires more air pressure. And of course, there is nothing better than being able to pick up the instrument tuned, with the correct spring pressure, the correct opening of the keys, and to play without having to press your fingers to get the notes out.

A Overhaul, involves complete disassembly and replacement of worn parts of the entire instrument. Sometimes the flautist may find that his instrument is in good pads just because it's not torn, but in many cases the lack of projection and difficulty in sounding the notes is linked to the dryness or swelling of the pads. The process of chimney grinding and key alignment (used for Straubinger pads) is very important when we talk about overhaul, but most of the instruments do not come with factory rectified chimneys, which is a differential of our work. The period between reviews depends on many factors, including instrument time and status and the frequency of C.O.A. The approximate average would be three to five years, being in day. By doing C.O.A and Overhaul correctly on your flute, you will have a new instrument for a good long time.


The Finishing Plating is the process of covering the substrate by layers of noble metals in the case of nickel, silver, gold and rhodium, which serve to protect the surface and give beauty to the piece. The work we do is totally professional and of great responsibility, taking into account to maintain the aspects determined by the manufacturers. The silver plate follows the quality standards as they are applied in the own factory, the gold plate is made by electrolysis, and a layer of gold 23k (carats) is deposited on the plate, and finished with the color of the desired content by the client . The Plating does not have the ability to cover corrosion, but a proper pre-treatment and polishing that guarantees a significant improvement in your instrument!
