Piano Repairs | Perth & Mandurah

A piano is as complex as your average motor car. Upright pianos have about 5000 moving parts and grand pianos have an average of 10,000 moving parts. If we service our car every 10,000km why do we neglect our piano? Musicians will say that music is an art and a passion. If you remember the old saying that a tradesman is only as good as his tools, think of the piano as the tools for that art and passion. It should be cared for and serviced to perform at its best, so you will perform at your best.

Regulation

The complex mechanism that causes the hammers to hit the string is called “The Piano Action”. It’s comprised mostly of wood, felt and leather. The action needs to be responsive to every level of the pianists touch, from fast and repetitive to hard and loud to light and soft. The only way to achieve this is by maintaining the action to its intended tolerances by a process called Regulation. The tolerance of the action parts declines with the age of the piano and regular use. The wood parts can dry and warp, felts compress and leather parts dry out. This all happens slowly over time and most pianists don’t even know because being a gradual change the pianist will also gradually adapt his or her playing and touch to compensate for the uneven touch and underperformance of the piano. This may cause the pianist to developed poor technique.

Voicing

Hammers have a lot to do with the overall tone of the pianos sound. When a pianists complains that the piano sounds tinny, metallic, bright or aggressive then its an indication that the hammers may need voicing. Hammers are made of compressed felt, and piano technicians are able to change the pianos tone by making the hammers a little softer in a process called voicing. Voicing is a matter of personal taste. Some people prefer a bright metallic piano and others prefer a well rounded, more mellow sound. The more the piano is played the harder and more compressed the hammers become and the result can sound very harsh and metallic. With time the hammers can become flat or grooved, and then a process of hammer filling can be used to try reshape the felt into a smaller end striking point. If this is not achievable then replacement of the hammer is advised.

Re-stringing

Piano strings hold a lot of tension and with age may start to corrode and start causing strange sounds. Strings will fatigue with age and are known to start breaking on tuning and seasonal change. It would then be advised to have your piano re-strung. This is a repair that is best performed in PianoTech’s workshop and not the customer’s home. When in the workshop, Pianotech will also replace the tuning pins, service the hammers and voice them as part of the re-string service.

Re-pinning

80% of old pianos have some loose tuning pins, It makes tuning hard and the length that the tuning will hold is diminished. In a lot of cases it is recommended that pianos should not be tuned with loose tuning pins, until repair work is carried out. Think of an Guitar with a faulty tuning peg, you try to wind the string up to pitch but once you remove your hand the peg unwinds, making tuning impossible. This is what happens with the tuning pins of your piano. The tuning pins are inserted into a wooden block called the tuning wrest plank. Over the years the wood drys and shrinks causing the friction fit of the tuning pin to become loose. Most times it is recommended to replace the tuning pins and the strings at the same time. Sometimes an upright piano has little value and a more economical repair is to only replace the tuning pins with over sized pins and save the existing strings if they are in reasonable condition. Loose tuning pins can sometimes be due to a larger problem such as a crack in the wooden tuning wrest plank. If this is the case for an upright piano, then we consider the piano to be beyond economical repair.

Perth Piano Restoration & Refurbishment

Pianos with sentimental or historic value may be a candidate for major restoration or just a refurbishment to get the piano looking and playing as close to the way it did when it was new.

This is a very involve process & requires a lot of skill, patience and labour. A total restoration can take over a year and a refurbishment could take over 6 months.

Total restoration would include refinishing the cabinet, replacement or repair of the soundboard and tuning plank, new strings and tuning pins, new hammers and action parts, new key tops and much more. Such a restoration can cost over $19,000 +. You need to evaluate the worth of your piano, be it sentimental or monetary. Be aware that after the restoration the piano may only be worth the market value & that could be a lot less that the money you have paid for its restoration.

A much preferred option is refurbishment of pianos. This is a process of going through the piano, finding the faults and correcting only what is needed. A “Spit N Polish” of your piano both inside and out and set to a budget in mind.  Such a refurbishment might include rejuvenation of Ivory key tops, polishing of the cabinet finish and brass work, re-shaping hammers, action regulation, replacing worn and missing felts and leathers, treating loose tuning pins or replacing all tuning pins so piano will hold tune.  Cost for such refurbishments can start from around $2500 +.
