Yes, we do them too!(Though not in the festival season, July - August). Refrets, new nut or saddle, loose bracing? No problem. We've done them all, from finding that annoying, elusive rattle or buzz, to restoring concert harps or rebuilding a double bass from the collapsed parts someone found in a cellar!
We will quote a price for a job after examining the instrument and discussing what you want. We don't charge for quotes, and we'll try to help if we possibly can.
