Is $30,000 to replace 26 windows (sash, custom, and full-construction) a fair price?

All 26 windows (mostly sash replacements, some custom and full-construction) have noticeable install issues—gaps, protruding wood inserts, and some sloppy mitered quarter round. I’m debating whether to call out the handful with bad quarter round or flag everything. They plan to just caulk it all once they have the rest of the windows installed. After reviewing several similar quotes, we chose them for being transparent, non-pushy, and thorough with options and design iterations. They seemed competent during planning and the work so far other than this, so am I overthinking this? I’m a detail-oriented homeowner who usually does the work myself, but this job was too big with a young family and full-time jobs. I just want the result to reflect the cost and care we put into choosing.
