Rebuild estimates/bridge pins

[David Love]

I'm not sure about a 25 year old piano.  That's fairly young.  I would
include the cost in the estimate, but a resurfacing of the bridge on a
piano of that age may not be necessary.  You'll have to make a judgment
when the strings are off and you can look at it.  What else are you
doing to it?  In cases like this I usually add an addendum to the
estimate indicating things that may need doing but can't be determined
until the piano is stripped down.  List the costs on those items and
have a built in range on the estimate, like 10 - 15%

Thanks David,

Wouldn't you think that a 25 yr. old university
practice room piano probably has notches in the bridge
pins from the strings?  I will just include this cost
since it is so likely.
