John Tye Piano Tuner
Maintenance
 
This is what I would normally do as part of a tuning unless there is a time constraint.

It would typically be a little regulation of one or two notes, dealing with a warped hammer or key, locating a squeak or rattle or tightening a screw on the music rest.

The other issue is identifying possible problems. Please do not let your piano get to this state:
(and this photo was taken after I had already replaced 9 strings!). If I had been alerted after the first string broke I would have found that the treble was tuned a whole tone sharp, so would have been able to save the other strings.
 
Loose Screws
This photo shows a hammer flange with a loose centre pin that is working its way out. This will be causing a wobbly hammer, which feels and sounds wrong and will cause damage if left. A loose screw will be the culprit. Just pushing the pin back will damage the felt and still leave the hammer wobbly, so the pin needs replacing. This is called re-centring, and is crucial to the operation of the action. The maintenance is of course to tighten these screws and the other action screws, some of which cause clicking noises and misaligned hammers.

Split Bridge

I was alerted to look into the bottom of the piano by this sound from the top bass notes. I am classing this as maintenance because the cost of the full repair (to make and install a new bass bridge) would be well on the way to a new piano. So, this being a 100-year-old piano, the bridge was glued and supported by screws to prevent it getting worse.
Metal plates (agraffes) were used to support the affected notes, and the strings threaded in the opposite direction to offset the force from the lower strings. The agraffes are pinned right through the bridge to the soundboard, so they help to keep the bridge together. This, as you might expect, is the sound of the repaired notes.
Though certainly not perfect, I charged 100 on top of the tuning fee, and the client has a working piano.

Nameboard Felt

You do not have to put up with an ugly gap behind the keys or some tatty strips of dirty felt. It can easily and cheaply be replaced. Red is the usual colour for this felt, but with superb woodwork like this piano I prefer a more tasteful brown.
