However even pianos that look like they will never break need some fixing from time to time. Nothing can resist time, main things that break in a piano are keys, strings and after a long period of time the paint will start to come off. Constant care will slow the process, but if the piano is used all the time and moved around, then sooner or later something will give.
Today, some excellent old pianos are not being used because they have been worn out. Since it happens so slowly, this frequently goes unnoticed. In many cases the restoration of a really old piano is so costly and time consuming that it’s easier to just leave it in a corner and buy a new one than deal with it.
A few professionals have what it takes to rebuild such instruments to their old state. This type of work is called remaking, restoring, or reconditioning.
Reconditioning is the procedure of returning a piano to its old condition by restoring the paint, fixing, and replacing the parts that are only 100% needed to replace. This is most suitable for a piano with not much wear or pianos that don’t cost very much.
Reconditioning does not include changing important parts e.g. the bigger parts in the piano like for example soundboard. Reconditioning is not the same as rebuilding, it’s just making your working, but old piano play and look like back in the old days.
Remaking is the process where the old piano is rebuilt to its original form. It includes replacing any or all the parts that are damaged or old, redoing the paint job or getting all new original parts for the insides of the piano. There are two types of rebuild, a full rebuild that includes changing everything and a half rebuild that includes changing only inside or the outside of the piano.
This process can return an old piano to an even better state that before and is usually performed on antique pianos and the cost of such procedure is quite costly and time consuming.
