The value of an instrument always depends on its condition. The condition can only be assessed on site. That is why the value can only be ascertained by your local technician. Regional supply and demand needs to be considered too. The Grotrian factory is not in the position to suggest a value.
Yes, the Grotrian factory does this kind of work, but only complete restorations. This includes the full acoustical system and the case. We have to stress that in most cases the costs for a total restoration exceeds the market value of the piano. Complete restoration means many parts are replaced with new ones. This will help the re-fit and to improve the original sound and touch. Please consider: Despite refurbishment the piano is still an old instrument and the design of the instrument itself is not altered.
The optimal condition is humidity between 45 and 55% and a constant temperature between 19 and 21°C.
Although the models keep their name, a continuous facelift of the Grotrian instruments leads to a permanent improvement. In case of hesitation the newer model should be preferred to an older one. Our certification DIN ISO 9001:2008 has been created a quality circle which is responsible for permanent improvement.
Beyond the legal product liability of 2 years Grotrian grants an additional 3-year warranty. This leads to a five-year warranty from the date of purchase if the service conditions are confirmed by sending in the warranty postcard stamped by your Grotrian dealer. The basic condition for this warranty is the evidence of a regular service executed by a registered Grotrian dealer. Case surfaces are excluded from the extended warranty. The necessary service interval is named in our warranty conditions. In the event of a warrantee claim the first point of contact must always be with the Grotrian dealer from whom you purchased the piano. Please read the conditions carefully.
Safe delivery and a competent after-sales service can only be guaranteed by experienced and skilled local dealers. A properly serviced piano ensures joy for years. That is why Grotrian instruments can only be purchased via selected Grotrian dealers.
