<HTML>Ron, I have a similar situation but this is in a large Catholic Cathedral here in Chicago. Marble floors, 3 story ceilings, an echo which never dies and a 6' Aeolian grand with steel reinforced hammers. My solution: ear plugs, late night tunings so that outside noises are at a min., also the custodian who just has to vacuum at the same time I am working is long gone, and I propose all sorts of expensive repairs for the piano each time.  (Looks like it is working, they are looking at a S&S D.) Oh yes, plenty of aspirin and frequent breaks, and I charge by the hour for every min. it takes. Andrew Remillard ANRPiano.com</HTML>
