If it was not maintained by them, keeping the caulk good at the tub and
if cracks developed they did not maintain the life is short, so counter
sue them for filing a frivilous lawsuit. Did you dislose nothing because
there was nothing wrong to you, then dont worry. Go to your courthouse
check records to see if they have done this before. It seems to be a
common issue, but if their claim is without merit you may collect.
