In the 28 years we have had our workshop in Hamburg-Altona, a multitude of clients have entrusted us with their instruments for revision, adjustment and repair.

Even if the instrument is not broken, all the components of your instrument and bow need to be checked and maintained on a regular basis to ensure optimal playability at all times. Well-maintained string instruments can enjoy an incredibly long life span!

We have invariably found our customers' demands and questions in this respect both demanding and inspiring.

Our business is designed to be a full service workshop; in other words, we provide you with all the services your string instrument requires through the years. 

To ensure a string instrument or bow remains optimally playable in the course of its long life, all of its components need to be checked, serviced, and overhauled on a regular basis. Such normal repairs include:

- cleaning and polishing the varnish

- glueing of open seams, fingerboards and necks

- new bridges and soundposts →sound adjustment

- fitting of new pegs or refitting of your existing pegs

- solid bushings and spiral bushings

- shooting and polishing fingerboards

- making and glueing of new fingerboards out of ebony or Corène©

- correction of fingerboard elevation or resetting the neck

- neck grafts ( if the neck is broken )

- cleaning and glueing of cracks

- fitting and glueing new bassbars

- fitting patches in tops and backs (such as sound post patches)

- retouching the varnish and other work on the varnish

- as well as →bow repairs.

Violins, violas, cellos, and their bows are primarily musicians' daily tools, and thus inevitably subject to a fair amount of wear and tear. But apart from this, master instruments are also works of art we need to safeguard for future generations.

They have to be kept in intact and optimal condition to ensure that their sound and their long-term value are maintained.

As violin makers, our task is to ensure the preservation of a master instrument’s structural strength, its aesthetics, and its personal timbre. Thus we treat your master instrument as a historical work of art.

Occasionally, when an instrument has suffered major accidents or has been poorly repaired after previous damage, it is in need of major restoration. We use the term “restoration” if not just one flaw requires attention, but an entire area of the instrument is affected.
In the course of a restoration, we can stabilize cracks, rebuild and reinforce sunken archings, or clean and refill certain areas where the varnish has worn away. While restoring the instrument’s structure and appearance, we apply the greatest care to preserve its original substance.

We can look back on over 25 years of experience in string instrument restoration. If your instrument is in need of a major workover, feel free to contact us.
