Maintenance, Repair and Modification Prices


Due to high demand some if the listed prices have increased by around 20%. I have had no time to correct these yet. Please phone if there are any questions or enquiries about pricing.

Quality for kids exchange program

 At this moment we need donor trumpets for our Q4K project. If you happen to have a Conn, King, Geuzen, Bundy, Olds, Besson or other quality instrument that is no longer in use it might be possible to use the instrument as (part of) a payment for our hours. This means you could exchange your old trumpet to (partly?) pay for repairs on your current instrument. If you think we might be able to do this then please contact us to ask for possibilities. Best is to already email us some pictures of the instrument you have to exchange.

Because we are not a shop, but instrument builders / repair service we tend to calculate hours. Every repair is different. This is why it isn’t easy to make a price list with set prices. The prices below are estimates, including 21% VAT (BTW for dutch people). So prices may vary. If more services are combined we always try to plan these in such a way that the price stays as low as possible. Work on Q4K instruments are against 30% reduced prices.

Care products (oil, brushes, etc) can be ordered or purchased at the workshop.
