Piano Castor Repair Service in South London
07958 575122
SW Pianos offer a piano castor repair service in South London.
I can also source replacement castors and wheels or offer alternative solutions. You will need to decide whether you require the piano restored to its original condition or to increase its mobility. You may only need to protect your floor.
When floor protection rather than mobility is the priority
Pack of 4 universal castor cupsIf you have old or seized metal piano castors that might damage your floor, I often recommend that the cheapest solution is to fit my gliding piano castor cups. These permit some limited movement while protecting the floor. However, they won't compensate for a completely collapsed castor.
When piano mobility is the priority
1) Identify the make and model of the piano. If the piano is old, that may not be possible. Take photos of the piano castor, or at least of an accessible castor to send to me.
2) It may be necessary to come and see the piano. If it is an upright piano, the visit will probably entail upending it to determine the problem, whether all 4 castors are the same, and how the underside of the piano is constructed.
There are dozens of possible designs specific to the size and weight of the piano and also to its intended use.
A piano intended for public spaces (schools and halls) might have large twin rubberised wheels. or even rear extensions or safety brackets to allow them to be wheeled safely around without the risk of toppling over.
The different undersides of upright pianos
Pianos built with a completely flat underside offer more options for replacing old castors with low-cost upgraded castors. The piano on the left has a centre keel. It needed some fettling to accommodate a 'rear toe kit'. The kit added stability, allowing it to be wheeled safely around a school hall. The piano on the right needed a low-cost castor solution which added mobility but did not reduce the risk of toppling backwards while being moved around a hall.
Some older UK piano models have irregular bases with the pedal linkages exposed, or with convex bases, or with recesses to house the castor plates.
An inspection visit may be needed to confirm the possible options.
Compact upright pianos
Not all upright pianos have wheels. In particular, pianos without support legs under the keyboard could be made unstable by the fitting of wheels. Some smaller pianos do have wheels, and their castors are often recessed into the underside of the piano to keep their centre of gravity low. They are often fitted with tiny wheels, which are impractical for moving the piano and can cause damage to floors.
If a piano castor repair is not appropriate, because you need to make your piano more mobile, you will need to fit a set of safety brackets.
